SUMMARY OF THE INVENTION

This invention relates to various embodiments of a composite web of pressure sensitive labels. The composite web is comprised of a web of supporting material and a web of label material having pressure sensitive adhesive releasably adhered to the supporting material web. The label material web is separated into labels by butt cuts that extend transversely across the web. The supporting material web is provided with a series of longitudinally spaced apart cuts. Each cut forms at least one flap or flap portion that extends initially in the plane of the supporting material web. In accordance with certain embodiments of the invention one flap or flap portion is formed as for example when the supporting material web is provided with a triangular-shaped cut, or two flaps or flap portions for example are formed .[.with.]. .Iadd.when .Iaddend.an I or T shaped cut is made. The cuts extend completely through the supporting material web and also preferably partly and most preferably entirely through the label material web. The cuts in the labels render the labels more difficult to remove when applied to merchandise. As the cuts in the label material are aligned with the cuts in the supporting material, the composite web can be loaded into a label dispensing apparatus having a toothed driver such as a feed wheel, and the teeth of the driver can poke through the supporting material and the label material at the localized zones of weakening provided by the series of cuts. This obviates the need to strip labels from the end portion of the supporting material web when loading the apparatus. In certain of the embodiments the cuts provide respective trailing flaps or flap portions which are located in the label supply roll such that the flaps extend away from the leading free end of the web and toward the end of the web adjacent, typically, the label core. The provision of trailing flap affords the distinct advantage over a leading flap in that the trailing flap does not fold out of the plane of the web as the supporting material web passes about the delaminator, and consequently tearing of the supporting material web is obviated. The invention is also directed to method of making such composite webs and method of dispensing such composite webs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the embodiment of FIGS. 1 through 8, and in particular to FIGS. 2, 3 and 4, there is shown acomposite web 30 oflabel material 31 releasably adhered to and carried by supporting orbacking material 32. Thelabel material 31 is cut transversely bytransverse cuts 33 extending all the way across the web .[.331.]. .Iadd.31 .Iaddend.of label material to the side edges 34 and 35 of thecomposite web 30, as best shown in FIGS. 2 and 4. Thecuts 33 known as "butt cuts" separate theweb 31 of label material into a series of end-to-end labels 36. The side edges of the label material as well as the supporting material are straight and the label material is coextensive with the supporting material.

The underside of theweb 31 of label material has a coating of pressure sensitive adhesive 37 which adheres strongly to theweb 31 of label material. The adhesive is shown to extend across the entire underside of the label material even to the side edges 34 and 35 of theweb 30. Theweb 32 of supporting material carries a thin film or coating (not shown) which allows the labels to be peeled from theweb 32 of supporting material.

Groups 38 of cuts are provided at equally spaced apart intervals along the length of thecomposite web 30. Eachgroup 38 of cuts is shown to extend through the supporting material as well as through the label material. Eachgroup 38 of cuts is shown to be made in a generally I-shaped configuration comprised of a straight longitudinal or vertical bar cut 39S in the supporting material and an aligned straight longitudinal or vertical bar cut 39L in the label material. Spaced from the one ends of thevertical bar cuts 39S and 39L are straight transverse or horizontal bar cuts 40S in the supporting material and 40L in the label material. Spaced from the other ends of thevertical bar cuts 39S and 39L are aligned straight transverse or horizontal bar cuts 41S in the supporting material and straight transverse or horizontal bar cuts 41L in the label material. The part of theweb 32 between the one end of the cut 39S and the cut 40S provides a frangible portion 43S and the part of theweb 32 between the other end of the cut 39S and the cut 41S provides a frangible portion 42S. In like manner, the part of the label material between the end of the cut .[.32L.]. .Iadd.39L .Iaddend.and thecut 40L provides afrangible portion 43L and the part between the other end of thecut 39L and the cut 41L provides afrangible portion 42L. As a variation of the illustratedgroups 38 of cuts, thecuts 40L and 40S can be omitted in which event the cut 39S will be extended by tearing as thetooth 48 engages theweb 32 at the cut 39S; this would result in groups of cuts each having a generally T-shaped configuratiion as shown in FIG. 25.

With reference .[.noew.]. .Iadd.now .Iaddend.to FIG. 1, thecomposite web 30 is shown to be in the form of a roll which can be wound on acore 44, as desired. The core 44 can receive a shaft 45 about which the roll is free to rotate in the direction ofarrow 46. The roll is wound in such a manner that the label material is one the outside in overlying relationship with respect to theweb 32 of supporting material.

A toothed driver generally indicated at 47 is shown to be in the form of a drivensprocket having teeth 48 disposed in a plane at equally spaced apart angular positions around the circumference of thedriver 47. Thedriver 47 is used to advance the composite web first to a printing zone at which a printer 48' and aplaten 49 are disposed. A relativelysharp peel edge 50 is diagrammatically illustrated as being disposed at the terminal end of the platen. The web of supportingmaterial 32 is drawn around thepeel edge 50 by thetoothed driver 47. Theedge 50 causes the supportingmaterial 32 to make an abrupt change in direction, thereby effecting delamination or peeling of the supportingmaterial 32 from onelabel 36 at a time as the web of supporting material is concomitantly advanced by thetoothed driver 47. An applicator 51 is positioned beyond thepeel edge 50 and on the same side of the label as the printer 48'. The applicator 51 is shown to take the form of a conventional applicator roll, however, other types of applicators such as a plunger, a presser foot, or the like can be used, if desired. Thecomposite web 30 approaches the printing and applying zones generally in the direction of anarrow 52, and after passing around thepeel edge 50 theweb 32 of supporting material advances generally in the direction ofarrow 53 and passes partially around a guide roller orshaft 54. From theguide roller 54, theweb 32 passes partially around thetoothed driver 47. From there theweb 32 passes partially around a guide roller orshaft 55 and from there theweb 32 is guided by means of guides in the direction of thearrow 56. Thetoothed driver 47 is driven stepwise by a pawl and ratchet mechanism so that upon operation of this mechanism thecomposite web 30 is advanced through the appropriate distance so that the labels can be printed at one or more stages and so that a label is brought to the applying zone at which the applicator 51 is effective to apply the dispensed label to merchandise M. Theweb 32 passes between the outer surface of thetoothed driver 47 and a guide or hold downplate 57 as shown in FIGS. 1, 6, 7 and 8. As thedriver 47 rotates, successive teeth engage successive groups of cuts in theweb 32. As a tooth engages theweb 32 at a longitudinal cut 39S frangible portions 42S and 43S are severed as by tearing to provide afeed hole 58. Thefeed hole 58 thus formed receives thetooth 48 and deflectsflaps 59 and 59'.

As best seen in FIG. 7, theguide 57 has aconcave section 60 with agroove 61 in the same plane as theteeth 48. The transversely extendingflaps 59 and 59' are shown to enter thegroove 61 when thetooth 48 is in thefeed hole 58. As best shown in FIGS. 6 and 7, eachtooth 48 terminates at a sharp pointed end 62 which serves to facilitate .[.serving.]. .Iadd.severing .Iaddend.of the frangible portions 42S and 43S. Theguide 57 hasflanges 63 and 64 which are in guiding engagement withedges 65 and 66 of theweb 32.

The spacing of theteeth 48 around the periphery of thedriver 47 is the same as the spacing of thegroups 38 of cuts lengthwise of thecomposite web 30. Theteeth 48 are identical and only one is shown in detail in side elevation in FIG. 8. In FIG. 8, thetooth 48 is shown to have involute contoured faces 67 and 68 which enable it to readily make afeed hole 58 in theweb 32 which has passed partially around guide .[.roller.]. .Iadd.rollers .Iaddend.54 and to move out of the feed hole easily just before theweb 32 passes partially around theroller 55. As shown in FIG. 8 theface 67 of thetooth 48 is shown to be in driving engagement with the leadingedge 69 of thefeed hole 58. The face 68 of thetooth 48 is shown to be slightly spaced from trailingedge 70 of the feed hole.

The groups ofcuts 38 do not substantially affect the integrity of theweb 32 until feed holes are made by the teeth of thedriver 47 or the like. There are no flaps or lids as in the prior art which result in weakening of theweb 32 at the delaminating zone where the strength of the web is particularly important. Also there are no flaps to result in possible interference with the feeding of the web. In addition, the types of cuts forming thegroup 38 make it feasible for thecomposite web 30 to be fed in either direction with equal efficacy. With the prior art U.S. pat. to E. C. Marshall No. 3,501,365 the composite web can be fed in only one direction using the cut edge. The invention is not limited to providing agroup 38 of cuts across the marginal ends of each label; while this is the preferred arrangement, thegroup 38 of cuts can extend across the marginal end of every other label, or thegroups 38 of cuts can be disposed within the periphery of each label or of every other label, if desired.

The embodiment of thecomposite web 30A shown in FIG. 9 is identical to the embodiment of thecomposite web 30 and is used in the same manner, except thecomposite web 30A has at least one short straight transverse cut 80 in each marginal edge of eachlabel 36a. There are, however, no cuts in the marginal edge ofweb 32a of supporting material. Thecuts 80 serve further to prevent switching of thelabels 36a once they have been applied to merchandise.

The embodiment of the composite web 30B shown in FIG. 10 is identical to the embodiment of thecomposite web 30A, except that the individual cuts of each group of longitudinally spaced apartgroups 38b of cuts intersect. Specifically, the composite web 30B has a web 31b of label material an aweb 32b of supporting material. Theweb 32b of supporting material has longitudinal or vertical bar cuts 90S which extend to transverse orhorizontal bar cuts 91S and 92S. Thecuts 90S, 91S and 92S define transversely extending flaps or .[.lipds.]. .Iadd.lips .Iaddend.93 and 94. The composite web 30B can be delaminated and advanced by the same apparatus as shown in FIGS. 1 and 6 through 8. Thecuts 91S and 92S provide feed holes that theteeth 48 of the toothed driver can enter as thedriver 47 rotates.

A longitudinal or vertical bar cut 90L is made in the label material simultaneously with the making of the cut 90S, and therefore these two cuts are in alignment. Cuts 91L and 92L are made in the label material simultaneously with the making of thecuts 91S and 92S, and therefore the cuts 91L and 92L are in alignment withrespective cuts 91S and 92S. Thecuts 90L, 91L and 92L in the label material provide a generally T-shaped cut in each marginal end of each label 36B and hence tend to prevent switching of the labels once they have been applied to merchandise.

Referring to the embodiment of FIGS. 11 through 14, there is shown acomposite web 30C comprised of a web of label material 31c. Transverse equally spaced apart cuts extend entirely across the web 31c of label material at equally spaced intervals to .[.proide.]. .Iadd.provide .Iaddend.labels 36c. Space apart short transverse cut 100S are formed in both marginal side edges of theweb 32c. Short straighttransverse cuts 100L are disposed in each marginal side edge of the label material 31c in alignment with respective cuts 100S in theweb 32c of supporting material. Each cut 100S in the supporting material and the associated cut 100L in the label material are preferably made simultaneously with the same cutting blade. With reference to FIG 14 a toothed driver 47c is shown to be rotating and in driving engagement with theweb 32c of supporting material to effect advance of the composite web 30c. Asteeth 48c engage theweb 32c they effect deflection offlaps 101 facilitated by a pair of adjacent cuts 100S, one cut 100S of each pair of cuts provides adrive face 102 at the place where the leading edge of therespective tooth 48c engages it.

Referring to the .[.embdiment.]. .Iadd.embodiment .Iaddend.of FIGS. 15, 16 and 17,composite web 30D is identical to thecomposite web 30C in the embodiment of FIGS. 11 through 14 except that both the label material 31d and theweb 32d of supporting material are provided with a group of at least three spaced apart cuts rather than a pair of spaced apart cuts. Specifically, transverse equally spaced apart groups ofcuts 110S are made in theweb 32d of supporting material. Shorttransverse cuts 110L are disposed in each marginal side edge of the web 31d of label material in alignment with .[.respect.]. .Iadd.respective .Iaddend.cuts 110S in the supporting material. Each cut 110S in the supporting material and the associated cut 110L in the label material are preferably made simultaneously with the same cutting blade. With reference to FIG. 17 atoothed driver 47d is shown to have a substantially smaller diameter than the toothed driver 47c (FIG. 14). Thecomposite web 30D is preferably made with at least three cuts in that thetoothed driver 47d has a small diameter and in that it is easier for the flaps 111 formed by thecuts 110S to be deflected as theweb 32d passes around thetoothed driver 47d. Adjacent flaps 111 of a group of flaps extend outwardly and make an acute angle with respect to each other. The labels are indicated at .[.36j.]. .Iadd.36d.Iaddend..

Referring now to FIG. 18, there is shown acomposite web 30E' having a web of label material 31e' and a web 32e' of supporting material. The web 32e' is engaged by atoothed driver 47e' having triangularly shapedteeth 48e'. Transverse equally spaced apart cuts 33e' extend entirely across the web 31e' of label material at equally spaced apart intervals to providelabels 36e'. Spaced apart short transverse cuts 120S are formed in both marginal side edges of the web 32e'. Shorttransverse cuts 120L are formed in each marginal side edge of the label material 31e' in alignment with respective cuts 120S in the web 32e'. Each cut 120S in the supporting material and the associated cut 120L in the label material is preferably made simultaneously with the same cutting blade. Thetoothed driver 47e' is shown to be rotating in driving engagement with the web 32e' of supporting material to effect advance of thecomposite web 30E'. Theteeth 48e' effect deflection of flaps 112 and engage drive faces 113 at one side of each cut 120S.

Referring to FIGS. 19 and 20 there is shown a wide composite web 30AW, for example, for making thecomposite web 30A. The web 30AW is shown being advanced in the direction of arrow A. The composite web 30AW is comprised of thelabel material 31a adhesively secured to aweb 32a of supporting material passing betweencutter roll 130 having a plurality ofknives 131 and a cooperatingbackup roll 132. Theknives 131 travel at the same linear speed as the speed of the web 30AW and serve to cut through theweb 31a of label material across its entire width to make thecuts 33. Acutter roll 133 and abackup roll 134 are disposed beyond thecutter roll 130 and thebackup roll 132. As the composite web 30AW passes between thecutter roll 133 and thebackup roll 134, knife blades orknives 135, 136 and 137 maketransverse cuts 80 in only theweb 31a of label material. Thereafter two lines of printing P are printed on theweb 31a byprint drum 138 and a cooperatingplaten roll 139. From there the composite web 30AW passes between acutter roll 140 and a cooperatingplaten roll 141. Thecutter roll 140 has spaced apartgroups 38K of cutter blades or knives. Eachgroup 38K of cutter knives comprises a longitudinal or vertical bar cutknife 39K, transverse or horizontal bar cutknife 40K and transverse or horizontal bar cut knife 41K. Eachgroup 38K of knives makes one group ofcuts 38a in thecomposite web 30A. As best shown in FIG. 20, theknives 39K, 40K and 41K cooperate with theplaten roll 141 with zero clearance. Accordingly, each of theknives 39K, 40K and 41K cut entirely through theweb 31a and theweb 32a, whereasknives 131 and 135, 136 and 137 of the respective cutter rolls 130 and 133 cut entirely through thelabel material 31a but not into theweb 32a.

After passing between thecutter roll 140 and theplaten 141 the composite web 30AW is slit into a plurality ofcomposite webs 30A by cooperatingslitter elements 142 and 143. Eachcomposite web 30A can now be formed into rolls.

Referring now to FIGS. 21 and 22, there is shown a composite web 30DW traveling in the direction of arrow A1. The web 30DW passes betweencutter roll 150 andplaten roll 151. The cutter roll has spaced apart cutter blades orknives 152 for makingcuts 33d at equally spaced apart intervals along the length of the web 30DW. Spaced beyond thecutter roll 150 and theplaten 151 are cutter rolls 153 and a cooperatingplaten roll 154. Thecutter roll 153 has groups ofknives 110K for makingcuts 110L in the label material and for simultaneously makingcuts 110S in the supporting material. Spaced beyond thecutter roll 153 and theplaten roll 154 are cooperatingslitter elements 155 and 156 which slit the web 30DW into a plurality ofcomposite webs 30D, and thesecomposite webs 30D can be formed into rolls. As evident from FIG. 22, acutter blade 152 cuts only through the label material 31d and not into theweb 32d of supporting material. However, the cutter blades orknives 110K are set to zero clearance with respect to theplaten roll 154 so that each cut 110S and its associatedcut 110L are made simultaneously by therespective knife 110K.

Referring to the embodiment of FIG. 23 and FIG. 24, there is shown acomposite web 30E which is identical to thecomposite web 30A (FIG. 9), except that thecomposite web 30E has agroup 38e of cuts illustrated as being arranged in a generally T-shaped configuration. Thegroup 38e of cuts is shown to be comprised of a straight longitudinal or vertical bar cut 160S in supportingmaterial 161 and an aligned straight longitudinal or vertical bar cut 160L inlabel material 162. Spaced from the one ends of thelongitudinal cuts 160S and 160L are horizontal or transverse bar cuts 163S in supportingmaterial 161 and 163L inlabel material 162. The part of the supportingmaterial 161 between the one end of the cut 160S and the cut 163S provides a frangible portion 164S and the part of thelabel material 162 between one end of thecut 160L and thecut 163L provides a frangible portion 164L. Thelabel material 162 is provided withtransverse cuts 33e extending all the way across theweb 162 of label material as shown in FIG. 23. Thecuts 33e separate thelabel material 162 intolabels 36e. Thecomposite web 30E differs from the embodiment of FIG. 9 in that it is shown to have a pair of short straighttransverse cuts 165 in each marginal edge of thelabels 36e. There are, however, .[.not.]. .Iadd.no .Iaddend.cuts in the marginal edge of the supportingmaterial 161. Thecuts 165 serve to prevent switching of thelabels 36e when applied to merchandise.

FIG. 24 shows a fragmentary portion of atoothed driver 47e having atooth 166 of a generally triangular shape but having adrive face 167 curved like thedrive face 67 of ofdriver 47. As atooth 166 initially engages the supportingmaterial 161, it will cause rupture of the frangible portion 164S and thetooth 166 will cause triangular-shaped flaps 168S to be formed as best shown in FIG. 24. Onetooth 166 is shown to be in driving engagement with the web of supportingmaterial 161 and theother tooth 166 is shown to be out of engagement with the supportingmaterial 161.

The embodiment of FIG. 25 is like the embodiment of FIG. 23 in providing generally T-shaped groups 38f of cuts, except that with thecomposite web 30F, longitudinal or vertical bar cuts 169S in supportingmaterial 170 meet transverse or horizontal bar cuts 171S. There are aligned longitudinal orvertical bar cuts 169L and transverse or horizontal bar cuts 171L in thelabel material 173. Transverse cuts 33f separate thelabel material 173 into labels 36f.Composite web 30F has short straighttransverse cuts 174 in each marginal side edge of the labels 36f. There are, however, no cuts in the marginal side edges of the supportingmaterial 170. Thecomposite web 30F can be fed by thetoothed driver 47e shown in FIG. 24.

Although the arrangement of cuts disclosed in FIGS. 10 and 25 diminishes the integrity of the web of supporting material, this construction is substantially entirely free of the deficiency of folding a flap or chad out of the plane of the web during delamination as in U.S. Pat. No. 3,501,365. Such folding out of a flap causes some adhesive, or gum as it is known in the art, adhering to the edges of the flap or chad to be pulled away from the label material during delamination. In addition, such a folded out flap or chad will transfer the adhesive to guiding and feeding surfaces of the apparatus and flap can cause interference to feeding when pulling on the web of supporting material by means of a toothed driver.

Referring to the embodiment of FIG. 26, there is shown acomposite web 30G. Eachgroup 38g of cuts, is shown in a U-shaped arrangement, and is comprised of transversely spaced apart longitudinal cuts 175S and a transverse cut 176S in the web of supportingmaterial 177. The cuts 175S are spaced from and in alignment with the ends of the cut 176S. The part of the supportingmaterial 177 between the ends of the cuts 175S and the cut 176S provide frangible portions 178S.Label material 179 has transversely spaced apart cuts 175L and a transverse cut 176L. The horizontal cuts 175L are spaced from the ends of the transverse cut 176L to providefrangible portions 178L. Thelabel material 179 is provided with transverse cuts 33g to provide the labels 36g. Thecomposite web 30G has short, straighttransverse cuts 180 in each marginal side edge of the labels 36g. There are, however, no cuts in the marginal side edges of the supportingmaterial 177. It is preferred to use thecomposite web 30G with thedriver 47 with itsteeth 48 which are shaped in the manner best shown in FIGS. 7 and 8 rather thanteeth 166 of a triangular shape as shown in FIG. 24.

In the embodiment of FIG. 28, there is shown acomposite web30H having groups 38h of cuts at regularly spaced apart intervals. Eachgroup 38h of cuts has a short transverse cut 181S and a pair of converging cuts 182S in the web of supportingmaterial 183. The leading ends of the cuts 182S are in transverse alignment with the transverse cut 181S. The one cut 182S is spaced from the one end of the cut 181S to provide a fold line 183S. The other cut 182S is spaced apart from the other end of the transverse cut 181S to provide a fold line 184S. The other ends of the cuts 182S are spaced apart to provide a frangible portion 185S.Cuts 181L and 182L are provided in web oflabel material 186 in alignment with respective cuts 181S and 182S in the supportingmaterial 183. Thecuts 181L, 182L, and short straighttransverse cuts 187 serve to prevent switching of the labels when applied to merchandise. In the embodiment of FIG. 28 it is preferred that eachgroup 38h of cuts be disposed between the end edges oflabels 36h defined bytransverse cuts 33h. As shown in FIG. 29,toothed driver 47e shows atooth 166, which has ruptured the frangible portion 185S in supportingmaterial 183, in driving engagement with the supportingmaterial 183. It is evident that flap 188S folds along each cuts 181S and the respective fold lines 183S and 184S. To insure rupturing of the frangible portion 185S, the length of the frangible portion 185S is about one-half as long as the fold line 183S and one-half as long as the fold line 184S. The lengths of the fold lines 183S and 184S and the cut 181S are equal.

Referring to the embodiment of FIG. 30, there is provided acomposite web30K having groups 38k of cuts. Eachgroup 38k of cuts includes curvilinear cuts 197S in a web of supportingmaterial 198. The one ends of the cuts 197S are spaced apart by a relatively substantial distance transversely of thecomposite web 30K. The other ends of the cuts 197S are spaced apart only a relatively small distance by a frangible portion 198S. Thegroup 38k of cuts also includescurvilinear cuts 197L in web oflabel material 199. Thecuts 197L are in alignment with the cuts 197S in the supportingmaterial 198.Transverse cuts 33k in thelabel material 199 define the ends of thelabels 36k. Thecuts 197L andcuts 200 in thelabel material 199 serve to prevent switching of the labels once they have been applied to merchandise.

With reference to FIG. 31, thetoothed driver 47e is shown to be in driving engagement with the web of supportingmaterial 198. One of theteeth 166 is shown to have ruptured the frangible portion 198S and to be in driving engagement with the supportingmaterial 198.

FIG. 32 shows an embodiment of a composite web 30L which is identical to the embodiment of FIG. 9, except that a composite web 30L is shown to have anadditional group 381 of cuts between the marginal end edges oflabels 361 formed bytransverse cuts 331. In addition, eachlabel 361 is shown to have two shorttransverse cuts 201 at each marginal side edge.

FIG. 33 shows acomposite web 30M of labels which is identical to the composite web shown in FIG. 23, except that anadditional group 38m of cuts is provided between the end edges of the labels formed bytransverse cuts 33m.

FIG. 34 shows another embodiment of thecomposite web 30N which is identical to the composite web 30 (FIG. 2), except that thegroups 38n of cuts penetrate, that is extend only partially through thelabel material 202 as best shown in FIG. 35. It is also apparent from FIG. 35 that thegroup 38n of cuts extends entirely through the supportingmaterial 203. While the construction shown in FIGS. 34 and 35 does substantially weaken the label material so as to render thelabels 36n more difficult to switch once they have been applied to merchandise, they are less effective in this connection than would be the case as in the embodiment of FIG. 9, for example. FIG. 36 is a view similar to FIG. 35 but showing where the longitudinal cut is made partially through thelabel material 204 by perforating instead of completely cutting through the label material as in the embodiments of FIGS. 1 through 9 or as opposed to the partial cutting through thelabel material 202 as disclosed in FIGS. 34 and 35. Thus, in the embodiment of FIG. 36,composite web 30P has thegroup 38p of cuts entirely through supportingmaterial 205 and through thelabel material 204 at spaced apart locations leaving tangs or lands 206 or the like between through-cuts 207.

It is within the scope of the invention to make thecuts 33, 39L, 39S, 40L, 40S, 41L, 41S, 90L, 90S, 91L, 91S, 92L, 92S, 33c, 100L, 100S, 110L, 110S, 33e', 120L, 120S, 33e, 160L, 160S, 163L, 163S, 33f, 169L, 169S, 171L, 171S, 33g, 175L, 175S, 176L, 176S, 33h, 181L, 181S, 182L, 182S, 33k, 197L, 197S, and 331, by means of scoring, perforating or the like instead of by completely cutting through the respective label or supporting material. It is, however, preferred to make each of those cuts which is to define a feed edge a through cut rather than a score or perforation cut.

Referring now to a label printing and applying apparatus generally indicated at 210 in the embodiment of FIGS. 37 through 62, and initially to FIG. 37, there is shown to be a housing or main frame generally indicated at 211. The housing orframe 211 is specifically shown to include a pair offrame sections 212 and 213. Disposed within thehousing 211 is a subframe generally indicated at 214 which comprises a pair ofsubframe sections 215 and 216. Theframe sections 212 and 213 mount aplaten 217 which includes apeel edge 218. A print head generally indicated at 219 is mounted by thesubframe 214. More specifically, theprint head 219 includes a plurality of selectablesettable printing members 220 in the form of endless printing bands mounted by aprint head frame 221. Extending from theframe 221 are a pair offlanges 222 and 223. Gear sections or specifically racks 224 and 225 are provided at the ends of therespective flanges 222 and 223.Opposed tracks 226 and 227 are formed on therespective flanges 222 and 223 to receivestraight ball bearings 228 and 229. Thesubframe sections 215 and 216 haverespective trcks 230 and 231. Theball bearing 228 is received in thetrack 226 of theflange 222 and in thetrack 230, and theball bearing 229 is received in thetrack 227 in theflange 223 and in thetrack 231. Theball bearings 228 and 229 have respective balls 228' and 229' rotatably held by respective tangs orholders 228" and 229". In this manner, theprint head 219 is mounted for movement, particularly reciprocating movement, toward and away from theplaten 217.

Thehousing 211 has a handle generally indicated at 232 and particularly each housing orframe section 212 and 213 has arespective handle portion 233 and 234. An operator generally indicated at 235 is shown to comprise a pivotally operatedlever 236 pivotally mounted by apost 237 at the lower end of thehandle 232. Thelever 236 is normally urged in a counterclockwise direction (FIG. 37) by atorsion spring 238 received about thepost 237. The pivotal movement of thelever 236 is limited by an adjustable stop block 239 received by thehandle 232 between thehandle portions 233 and 234. The upper end of the operatinglever 235 carries a pair of spaced-apartgear sections 240 and 241. Thegear sections 240 and 241 are shown to be in the form of spur gear segments.Gear sections 240 and 241 are in meshing engagement with respective spur gears 242 and 243. The spur gears 242 and 243 are in meshing engagement withrespective gear sections 224 and 225 carried by theprint head 219.

A roll of pressure sensitive labels, in the form for example of thecomposite web 30 shown in FIG. 2, is mounted by itscore 44 by thesub-frame 214. As will be described in greater detail hereinafter, thecomposite web 30 is drawn off the roll into overlying relationship with respect to theplaten 217 and the supportingmaterial 32 is engaged by atoothed driver 244. Thegear 243 carries anintegral pawl 245 cooperable with aratchet wheel 246 which is coupled to thedriver 244 by a detent mechanism generally indicated at 247. An input or drivemember 248 of thedetent mechanism 247 is shown in FIG. 37. Thetoothed driver 244 has a plurality of equally spaced apart driveteeth 249 arranged about its outer periphery. Thepawl 245 is integrally joined at but one end to thegear 243. Thepawl 245 is flexible and resilient and can ride on theratchet wheel 246 and deflect into engagement with atooth 265 of theratchet wheel 246.

The housing offrame section 213 has anaccess opening 250. Acover 251 is removably connected to theframe section 213 at theaccess opening 250. Thecover 251 mounts aninking mechanism 252 cooperable with theprinting members 220 of theprint head 219. Thehousing sections 212 and 213 mount anapplicator 253 disposed downstream of thepeel edge 218.

Referring to FIG. 38, the interrelationship of the components of theapparatus 210 is shown in detail. Thecomposite web 30 is paid out of the roll and passes through a passage provided bysubframe sections 215 and 216 and specifically by groove 254 (FIG. 44) in thesubframe section 215 and a cooperating groove 255 (FIGS. 37, 38 and 42) in thesubframe section 216. From there thecomposite web 30 passes partly around aroll 256 and into overlying relationship with theplaten 217. Delamination is effected at thepeel edge 218 formed at the end of theplaten 217. The supportingmaterial 32 is drawn around thepeel edge 218 beneath theplaten 217 and passes partly around aroll 257, below theguide 258 and between thetoothed driver 244 and themating die wheel 259. As atooth 249 moves into mating cooperation with thedie wheel 259, thetooth 249 engages the supportingmaterial 32 at the longitudinal cut 39S and effects rupturing or bursting of the frangible portions 42S and 43S, whereupon thetooth 249 which is in mating cooperation with the die wheel 259 (FIG. 53) is considered to have formed a feed hole in the supportingmaterial 32. It is preferred that there be threeteeth 249 in driving engagement with the supportingmaterial 32 at all times. Thesubframe sections 215 and 216 have respective alignedstrippers 260 and 261 which facilitate disengagement of theteeth 249 with the supportingmaterial 232 as thedriver 244 rotates.Opposed guide grooves 262 and 263 formed in thesubframe sections 215 and 216 guide the supportingmaterial 32 to anexit opening 264. Excess supporting material which dangles from theapparatus 210 can be readily torn off at theexit opening 264.

With reference to FIG. 38, theprint head 219 is shown by solid lines in the initial or home position and by phantom lines 219' in the printing zone in printing cooperation with thelabel 36 and theplaten 217. Theoperator 235 is shown by solid lines in its initial or home position and in phantom lines 235' in the fully actuated position. In the fully actuated position, theprint head 219 has been moved into printing cooperation with thelabels 36 and theplaten 217, and theoperator 235 is in abutment with thestop block 239. In this position of theoperator 235, the flexible resilient pawl 245 (FIG. 50), joined integrally at one end to thegear 243, has moved to the position shown by phantom lines 245' in driving cooperation with atooth 265 of theratchet wheel 246. When the user releases theoperator 235, the spring 238 (FIG. 38) returns theoperator 235 against stop 239' to the solid line position shown in FIG. 38. While theoperator 235 is returning to the solid line position from the fully actuated position indicated by phantom lines 235', thegear sections 240 and 241 (FIGS. 38 and 39) rotategears 242 and 243 clockwise (FIG. 38) to return theprint head 219 to the solid line position from the position shown by phantom lines 219', and to drive thepawl 245 from the position shown by phantom lines 245' to the position shown in solid lines in FIG. 50. Thus, thepawl 245, which is in engagement with atooth 265, drives theratchet wheel 246 counterclockwise (FIG. 50). This counterclockwise rotation of the ratchet wheel 246 (FIG. 50) causes thedriver 244 to advance the supportingmaterial 32 to effect substantially complete delamination of a label at thepeel edge 218. Counter-clockwise rotation of theratchet wheel 246 continues until a pawl 266 (FIGS. 37, 42 and 50) in the form of a flexible resilient appendage of thesubframe section 216, moves into engagement with atooth 265 of the ratchet wheel. This prevents the web of supportingmaterial 32 from being accidentally moved in the return direction.

As best shown in FIG. 39, thedriver 244 has anannular rim 267 joined to ahub 268 by aradial web 269. Thehub 268 has a hub section 268' extending in one direction and anotherhub section 268" extending in the opposite direction. The hub section 268' terminates at aknob 270, and the hub section .[.269".]. .Iadd.268" .Iaddend.terminates at a knob 270'. Thegear 242 is rotatably journaled on and with respect to the hub section 268'. Thegear 242 has a hub orflange 271 which is rotatably journaled in opening 272 in theframe section 212. The hub section 268' extends through anenlarged opening 273 in thesubframe section 215. Thehub section 268" provides a stepped pair of bearing surfaces 274. Theratchet wheel 246 is formed integrally with thedrive member 248 of thedetent mechanism 247. Theratchet wheel 246 and thedrive member 248 have ahub 276 with a steppedbore 275 into which thehub section 268" extends. Ahub 276 rotatably receives and mounts thegear 243. Thegear 243 has ahub 277 rotatably received in abearing 278 formed integrally with thehousing section 213. As seen in FIG. 39, thegears 242 and 243 are in driving engagement withrespective gear sections 224 and 225 carried by theprint head 219; the relative position of thedrive pawl 245 to theratchet wheel 246 is also shown.

With reference to FIG. 50, thedrive member 248 includes a plurality of spring fingers ordetent pawls 278. Thepawls 278 are of equal length, are flexible and resilient, and are continuously urged againstteeth 279 formed on the inside of theannular rim 267. In the illustrated embodiment there are one hundred and seventy-seventeeth 279 at equally spaced-apart intervals. There are twelvepawls 278 integrally connected to thehub 276 at equally spaced-apart intervals. Theteeth 279 comprise respective tooth faces 280 and a recess between adjacent tooth faces 280 in which the end of apawl 278 can be received. Thepawls 278 drive thefeed wheel 244 in a driving direction (counterclockwise in FIG. 50) but can move in a non-driving direction (clockwise in FIG. 50) relative to thefeed wheel 244 by manually operating thedetent mechanism 247. Accordingly, everyfifth pawl 278 is engaged with theface 280 of atooth 279. Thepawls 278 between every fifth set of pawls are out of engagement with their respective tooth faces 280 by different increments as best illustrated in FIG. 51. Normally, thepawls 278 hold theratchet wheel 246 and the feed wheel ordriver 244 in fixed relationship with respect to each other. With reference to FIG. 50, as thedrive pawl 245 moves counterclockwise theratchet wheel 246 is driven counterclockwise and the threepawls 278 which are in driving engagement with their respective tooth faces 280 will drive thefeed wheel 244 counterclockwise. Accordingly, there is .[.not.]. .Iadd.no .Iaddend.relative rotation between theratchet wheel 246 and thefeed wheel 244. Should it be desired to change the position to which the labels are advanced by thefeed wheel 244 upon actuation of theoperator 235, the user will grasp theknobs 270 and 270' and will rotate the knob 270' counterclockwise (FIG. 37) relative to theknob 270. This will cause theinput member 248 to rotate (counterclockwise in FIG. 37, clockwise in FIG. 50) relative to thefeed wheel 244 so that the next three successive teeth move into engagement with the next three respective tooth faces 280. For example, if it is considered that first, fifth andninth pawls 278 were initially in engagement withrespective teeth 279, only a very slight rotation will cause second, sixth and tenth pawls to move into engagement with their respective tooth faces 280, and so on. Although any desired number ofpawls 278 andteeth 280 can be used, the illustrated embodiment provides very minute adjustment of the fedwheel 244 relative to theplaten 217 and thepeel edge 218 and the arrangement ofteeth 280 and cooperatingpawls 278 causes the entire input or drivemember 248 to be centered within theannular rim 267. With respect to the printing function, adjustment of thedetent mechanism 247 changes the position relative to the printing zone between theprint head 219 and theplaten 217 to which a label .[.26.]. .Iadd.36 .Iaddend.is advanced. With respect to the delaminating function, operation of thedetent mechanism 247 also changes the position to which thelabel 36 is advanced. Accordingly, it is apparent that thedetent mechanism 247 is useful both in establishing the position to which a label is advanced relative to the printing zone and to the delaminating zone. It is important that just the correct amount of trailing marginal end edge of the label remain adhered to the peel edge so that thelabel 36 is held in that position until it is ready to be applied to merchandise by theapplicator 253.

As best shown in FIGS. 50, 52, and 53, the supportingmaterial 32 is initially brought into engagement with thefeed wheel 244 as it passes around thedie wheel 259. Thedie wheel 259 is comprised of anannular plastic roll 281 journaled bysubframe sections 215 and 216. Theroll 281 has frictional members in the form of rubber O-rings 282 received at spaced-apart locations about the periphery of theroll 281. The O-rings straddle theteeth 249 and are just spaced apart far enough to act as a die wheel withmating teeth 249. As atooth 249 begins to engage the web of supportingmaterial 32 at the cut 39S (FIG. 2), thedie wheel 259 cooperates with thetooth 249 to hold the supportingmaterial 32 on each side of thegroup 38 of cuts in intimate contact with the outer surface of thefeed wheel 244 as best shown in FIG. 53. This insures that thetooth 249 properly bursts or forms a hole, facilitated by thegroup 38 of cuts, in the supportingmaterial 32 and that the drive face of thetooth 249 is in driving engagement with the leading cut 41S. When thefirst tooth 249 registers with thegroup 38 of cuts in the supportingmaterial 32 thecomposite web 30 is properly registered with the printing zone and the delaminating zone. Once such registration is accomplished as the result of thetooth 249 cooperating with thedie roll 259, correct registration continues.

Theplaten 217 and the peel edge 218 (FIGS. 37 and 38) are formed from an inversely-bent plate having a pair of side-by-side plate portions 283 and 284 joined by an inversely-bent portion 285. The inversely-bent portion 285 has a small radius and defines thepeel edge 218. Theplaten portions 283 and 284 are co-extensive and are secured to each other byweldments 286. The plate which forms theplaten 217 and thepeel edge 218, received in recesses 286' insubframe sections 215 and 216, is preferably constructed of highly polished stainless steel. The sides of the plate that forms theplaten 217 and thepeel edge 218 are received in opposed recesses 286' in thesubframe sections 215 and 216. A label stopper is provided by a pair of alignedplates 218' formed integrally with thesubframe sections 215 and 216. Theplates 218' are disposed beneath but are spaced from theplate 217. Should alabel 36 attempt to fall onto the supportingmaterial 32 after being delaminated at thepeel edge 218, thelabels 36 will be caught by theplates 218'. This will prevent anylabel 36 from continuing along the path through which the supportingmaterial 32 passes after passing thepeel edge 218.

With reference to FIG. 38, thestop block 239 is shown to be slidable on astop surface 287. Thestop block 239 has a threadedbore 288 which threadably receives an adjustedscrew 289. One half of thescrew 289 is rotatably received in asemi-circular groove 290 and one-half of thehead 291 of thescrew 289 is captive in a semi-circular recess 292 in aseat 293. Thehandle portion 233 of theframe section 212 provides another stop surface (not shown) for thestop block 239 in alignment with thestop surface 287, another semi-circular groove (not shown) opposite thegroove 290 for receiving the other one-half of thescrew 289, and another semi-circular recess (not shown) opposite the recess 292 for receiving the other one-half of thehead 291. Ahole 294, one-half of which is formed by eachhandle portion 233 and 234, enables entry of a tool (not shown) by which thehead 291 of thescrew 289 can be engaged to rotate thescrew 289. Rotation of the screw in one direction will cause the stop block 239 to move upwardly (FIG. 38) and rotation of thescrew 289 in the opposite direction will cause the stop block 239 to move downwardly (FIG. 38). It is apparent that adjustment of the position of the stop block 239 will adjust the limit of the travel of theoperator 235.

With reference to FIG. 48, theinking mechanism 252 is shown to comprise a one-piece inker body 295 having an aligned pair ofsockets 296 having convergingopenings 297. Thesockets 296 extend for more than 180° so that theink roll 298 can be snapped into thesockets 296. Theinker body 295 has a pair of alignedprojections 299 which are capable of being snapped into sockets 300 (FIG. 37) in thecover 251. Thesockets 300 are shaped like thesockets 296. Theinker body 295 has an integrally formed leaf spring orspring finger 301 which is shown in FIG. 49 to be urged against thecover 251. Thespring finger 301 normally urges theinking mechanism 252 into the solid line position shown in FIG. 49. Theink roller 298 is shown in FIG. 49 to be in the path of but slightly spaced from theprint head 219 because in that position theinker body 295 contacts theframe 221 of theprint head 219. When theprint head 219 is moved from the solid line position to the phantom line position, theink roll 298 applies ink to the printingbands 220 and theentire inking mechanism 252 pivots aboutprojections 299 to the position shown in phantom lines. When theprint head 219 returns to the solid line position shown in FIG. 49, thespring finger 301 returns theinking mechanism 252 to the solid line position.

With reference to FIG. 48, theink roller 298 is shown to comprise a pair ofhub section 302 and 303. Thehub section 302 has an elongatedprojection 304 at one end and astub end 305 at its opposite end. Thehub section 302 has anannular flange 306 between thestub end 305 and a reducedportion 307. The reducedportion 307 is disposed between theflange 306 and theprojection 304. Theother hub portion 303 has anannular flange 308 disposed between a reducedportion 309 and astub end 310. The reducedportion 309 has a bore 304' into which theprojection 304 is adapted to be press-fitted. Theprojection 304 has straight flutes which serve to lock thehub portions 302 and 303 together. An ink-receptive tubularporous roll 311, composed for example of rubber or the like, is received on the reducedportions 307 and 309 ofrespective hub sections 302 and 303. Theflanges 306 and 308 abut the ends of theroll 311 and prevent theroll 311 from shifting.

With reference to FIGS. 42, 43 and 44, thesubframe sections 215 and 216 are shown to have respectiveintegral leaf springs 312 and 313. The leaf springs 312 and 313 are provided with integralannular brake members 314 and 315 having respective annular brake surfaces 316 and 317.Brake members 314 and 315 are formed integrally with projections orhubs 318 and 319,surfaces 318' and 319' of which are received in andmount label core 44. The brake surfaces 316 and 317 cooperate to exert braking forces on thelabel core 44. Neither thehubs 318 and 319 nor thebrake members 314 and 315 contact thecomposite web 30 which is wound on thelabel core 44. In this manner, any gum or adhesive that may .[.exit.]. .Iadd.exist .Iaddend.at the marginal side edges of thecomposite web 30 will not be transferred to the brake surfaces 316 and 317. FIG. 45 illustrates, in exaggerated form, by phantom lines, the initial positions of theleaf springs 312 and 313, thebrake members 314 and 315 and thehubs 318 and 319. The initial canted position of theleaf springs 313, thebrake members 315 and thehub 319 relative to the remainder of thesubframe section 216 is also shown in FIG. 43. Insertion of thelabel core 44 onto thehubs 318 and 319 will cause theleaf springs 312 and 313 to flex outwardly and the brake surfaces 316 and 317 will exert a predetermined braking force on the ends of thecore 44. The braking force applied to the core 44 will insure that there is tension in theweb 32 of supporting material from the label roll to the printing zone, to thepeel edge 218, and to thetoothed driver 244. As the pawl 266 (FIG. 50) prevents the reverse rotation of thedriver 244, it is seen that the apparatus maintains a slight but desirable amount of tension on the web of supportingmaterial 32 at all times.

Theframe 211 comprises an essentially closed shell but the rear part provides an access opening 211' through which a roll of labels can be inserted and a spentcore 44 can be removed without even partial disassembly of theapparatus 210.

With reference to FIGS. 55 through 58, there is shown theapplicator 253 mounted by theframe 211. Theapplicator 253 comprises ahub 320 shown to have four annular generally V-shapedgrooves 321 in whichrespective wheels 322 are rotatably mounted. Thehub 320 also has a pair ofannular flanges 323 disposed between the set of threewheels 322 and the remainingwheel 322. Thewheels 322 have greater diameters than theflanges 323. The ends of thehub 320 beyond thegrooves 321 are stub ends 324.Undercuts 325 inboard of the stub ends 324 enable the hub to be retained in cooperatingyieldable sockets 326 and 327 inframe sections 212 and 213. Thesockets 326 and 327 are comprised of a plurality of separate socket sections or flexibleresilient fingers 328 and 329 to enable the stub ends 324 to be snapped into place. Thesockets 326 and 327 and the cooperating stub ends 324 provide opposed snap-fit connections.

Thewheels 322 are identical so only one is described in detail. Eachwheel 322 is comprised of anannular rim 330 having anannular groove 331 in its outer periphery. A rubber O-ring 332 is received in thegroove 331. A plurality of equally spaced-apart arms 333 formed integrally with therim 330 have generally V-shapedbearing sections 334 received in therespective groove 321. The bearingsections 334 of thearms 333 exert forces against thehub 320, but enable thewheel 322 to rotate relative to thehub 320 and enable the .[.wheels.]. .Iadd.wheel .Iaddend.322 to yield as alabel 36 is being applied to the merchandise.

As the rubber O-rings 332 have a high coefficient of friction, rotation of thewheels 322 during label application is facilitated. The spacing of thewheels 322 allows theapplicator 253 to press thelabel 36 onto the .[.mechandise.]. .Iadd.merchandise .Iaddend.without contacting the printing which was applied to thelabels 36 by theprint head 219. As the label is pressed onto the merchandise, thearms 333 allow the wheels to yield. This yielding action is particularly useful when applying labels to merchandise having irregular surfaces in that thewheels 322 are mounted for both independent rotational and independent yielding movements with respect to each other. Theflanges 323 prevent theadjacent wheels 322 from deflecting more than a small amount away from the perpendicular with respect to thehub 320.

Referring to FIG. 59, there is shown an exploded view of theprint head 219. Theprint head frame 221 is shown to comprise aside plate 335 to which theflanges 222 and 223 are joined. A mountingblock 336 is molded integrally with theside plate 335. Theblock 336 has a platen orpressure member 337 and arcuate mounting surfaces 338. The mountingblock 336 also has asocket 339 for receiving aprojection 340 of theother side plate 341. Apost 342 is formed integrally with theside plate 335 in axial alignment with ahole 343 in theside plate 341. A pair ofposts 344 formed integrally with theside plate 335 havehooks 345 which engageshoulders 346 of theside plate 341. Theside plate 341 hasprojections 347 which are adapted to fit underprojections 348 on theblock 336. When theprojections 347 are positioned underneath theprojections 348, that is, between theprojections 348 and theside plate 335, theprojection 340 is received in thesocket 339, and when thehooks 345 are in engagement withshoulders 346, then theframe 221 is securely but releasably locked together.

The printingbands 220 are mounted in theframe 221 as best shown in FIG. 60. The printingbands 220 are urged against the support orpressure member 337 and are detented becauseteeth 349 formed on the underside of each of the printingbands 220 are in engagement withnotches 350 formed on the side of thesupport 337. In this position, theprojection 340 is shown received in thesocket 339, the printing bands are trained partially around driven members in the form ofwheels 351, the printingbands 220 are under slight tension, and the wheels are cradled in and rotatable on the mounting surfaces 338. Thewheels 351 havenotches 352 in which theteeth 349 are received.

Eachprinting band 220 has a plurality of printing blocks 353. The different printing blocks 353 of eachprinting band 220 can print different data, as in conventional. The printing blocks 353 are contained in aprinting section 354 of theprinting band 220. Theprinting band 220 also contains a non-printing humanreadable section 355. The humanreadable section 355 contains human readable indicia. The user knows what data the printing block 353 at thepressure member 337 will print by peering through awindow 356.

It .[.if.]. .Iadd.is .Iaddend.often desirable to change the data which theprint head 219 is to print. This is generally accomplished by advancing theprinting band 220 to the printing position in which the selected data will be printed on the label. A selector, generally indicated at 357, has aknob 358 and a shaft ortubular portion 359 received by thepost 342. Theselector 357 is freely rotated about thepost 342 and is movable axially so that its driving members or lugs 360 can be shifted into driving cooperation with any one of the drivenmembers 351. Each drivenmember 351 has acentral hole 361 which is provided with a plurality ofnotches 362 for receivingrespective lugs 360. Each drivenmember 351 is also chamfered at thecentral hole 361 as best indicated at 363. In addition to the driving lugs 360, theselector 357 is shown to have a pair of opposed pawls orspring detent fingers 364, the ends of which engage the recesses provided by thechamfering 363. The detent fingers .[.346.]. .Iadd.364 .Iaddend. serve to hold theselector 357 in the axial position to which it is manually shifted, but enable theselector 357 to be shifted to any desired position so that its drivingmembers 360 will be in driving engagement with the selected drivenmember 351. Accordingly, by shifting theselector 357, any one or all of the drivenmembers 351 can be rotated, one at a time, which results in the respective printing band or .[.hands.]. .Iadd.bands .Iaddend.220 being selectively moved to the selected position to print the selected data on the labels.

The driving lugs 360 are spaced slighted from the ends of the recesses ornotches 362. Should the user attempt to turn theknob 358 so as to apply excessive torque to theselector 357, the driving lugs 360 will deflect and move out of the set ofnotches 362 in which they are positioned in the drivenmember 351 and will move into the next set ofnotches 362 in the same drivenmember 351. Accordingly, there will be relative rotation between theselector 357 and the drivenmember 351 in which thelugs 360 are received.

There is a spacer .[.356.]. .Iadd.365 .Iaddend.between each of the drivenmembers 351 andbands 220. Each of thespacers 365 has a pair of lugs 365' which engage around theends 366 at the ends of the mountingsurface 338.

Theselector 357 is provided with anannular groove 367 adjacent theknob 358. An indicator, generally indicated at 368, has asplit collar 369 with aprojection 370 received in thegroove 367. Theindicator 368 has arectangular section 371 which defines thewindow 356. Theposts 344 have tongues or guides 344' which are in engagement ingrooves 372 in therectangular section 371. A pair ofpointers 373 disposed on the inner surface of therectangular section 371 are in alignment with thelugs 360 on theselector 357. Accordingly, thepointers 373 indicate the position of thelugs 360 so that if theselector 357 is not in position to drive the desired drivenmember 351 and its associatedprinting band 220, theselector 357 can be shifted to a position in which thelugs 360 are in driving engagement with the desired drivenmember 351 to advance the associatedprinting band 220 to the selected position.

As shown in FIG. 59, theside plate 341 has a projection or lug 374 by which theprinting head 219 is guided by theframe sections 212 and 213 byrespective guides 375 and 376 (see FIGS. 37, 38, 49).

The housing orframe sections 212 and 213 are connected by identical snap-fit connections including generally snap-shaped flexibleresilient members 377 arranged along the periphery of thehousing section 212 and engaged in undercutrecesses 378 in thehousing section 213. One of these snap-fit connections is shown in detail in FIG. 40.

Thesubframe sections 215 and 216 of thesubframe 214 are connected to each other and theframe sections 212 and 213 of theframe 211 are connected to thesubframe 214 by means of three sets of identical snap-fit connections generally indicated at 379, one of which is shown in detail in FIG. 54. With reference to FIG. 54, theframe sections 212 and 213 haverespective sockets 380 and 381 comprised of a plurality of respective flexibleresilient fingers 382 and 383. Thesubframe section 215 has aprojection 384 snap-fitted into thesocket 380. Theprojection 384 has a plurality of flexibleresilient spring fingers 385. Thesubframe section 216 has aprojection 386 comprised of a plurality of flexibleresilient fingers 387 snap-fitted into thesocket 381. Thesubframe section 215 has aprojection 388 comprised of a plurality of flexibleresilient spring fingers 389 received in asocket 390. Thesocket 390 is comprised of flexibleresilient spring fingers 391. Aprojection 392 formed integrally with theframe section 212 extends through thesocket 380, through theprojection 384, and to about the end of theprojection 388 in thesocket 390. Thespring fingers 383 of thesocket 381 are made thinner and consequently more flexible than thespring fingers 382 of thesocket 380. An attempt to open up theframe 211 by separating theframe sections 212 and 213 will cause theframe section 213 to be separated from thesub-frame section 216. Theframe section 212 will remain connected to thesubframe 214. As theframe section 213 is being separated from thesubframe 214, theprojection 392 prevents thesubframe sections 215 and 216 from separating because thespring fingers 389 cannot deflect inwardly because of the interference provided by theprojection 392. Once theframe section 213 has been removed, the inside of theapparatus 210 is exposed. It is apparent that accidental unsnapping of thesubframe 214 or theframe section 212 from thesubframe 214 is obviated by this construction. Further disassembly can be accomplished by deliberately unsnapping thesubframe 214 from theframe section 212. This is accomplished by moving theprojection 384 out of thesocket 380. When this has been accomplished, theprojection 392 has moved out of the space between thespring fingers 389 of theprojection 388 and consequently thesubframe sections 215 and 216 can be separated.

With reference to FIGS. 42 through 44 for example, thesubframe section 216 is shown to have fourprojections 393 which are adapted to be snugly received inrecesses 394 at the end of theguide 262. Theprojections 393 received in theholes 394 assist in removably holding thesubframe sections 215 and 216 together.

With reference to FIGS. 37 and 49 thecover 251 is shown to have an L-shapedflange 395 at one end and aprojection 396 at its other end. To attach theinking mechanism 252 to the apparatus, theprojection 395 is pushed under ashoulder 397 of theframe section 213 and thereafter thecover 251 is snapped into position by causing theprojection 396 to snap under a lip 398 of theframe section 213. In this manner, the inking mechanism orinker 252 is removably mounted to the apparatus. To remove the inking mechanism, the user can engage his fingernail beneath anextension 399 of thecover 251, thereby causing theprojection 396 to snap around the lip 398.

With reference to FIG. 41, theoperator 235 is shown to pivot on thepin 237. It is preferred to pivot theoperator 235 at the lower end of thehandle 232 in that the user's strongest fingers, namely his index, middle and ring fingers engage theoperator 235 at substantial distances from thepivot pin 237, while the user's relatively weak little finger is close to thepivot pin 237. The ends of thepin 237 are undercut as indicated respectively at 403 and 404. The ends 401 and 402 are received insockets 405 and 406 inrespective frame sections 212 and 213. Thesockets 405 and 406 are comprised of respective flexibleresilient fingers 407 and 408. Theoperator 235, as best shown in FIGS. 38 and 39, is shown to be generally U-shaped in section.Legs 409 and 410 are shown to be rotatably received about thepin 237. The spiral ortorsion spring 238 is shown to be received onpin 237 between thelegs 409 and 410. If it is desired to remove theframe section 213, theframe section 213 is moved relatively away from theframe section 212 causing thesocket 406 to move out of snap-fit engagement with theend 402. Only when theoperator 235 is moved away from theframe section 212 can theend 401 move out of thesocket 405 because of interference caused byleg 409. This construction obviates accidental disconnection of thepin 237 from theframe sections 212.

With reference to FIG. 63, there is shown an alternative construction by which aselector 357a having a plurality of drivinglugs 360a like thelugs 360 and also having a pair of opposed pawls 364a, selectively controls the setting of a selected driven member or wheel 351a. The embodiment of FIG. 63 differs from the embodiment of theprint head 219 shown for example in FIGS. 59 through 62 in that each of the driven members 351a is provided with an internalannular groove 411 and the chamfering 363 (FIG. 62) is omitted. Accordingly, instead of having thepawl 364a engage between adjacent drivenmembers 351 as shown in FIGS. 61 and 62 for example, thepawls 364a engage in thegroove 411 of one of the driven members 351a, and as is preferred in thegroove 411 of the same wheel with which thelugs 360a are in driving engagement. By this construction, the driving function as well as the detenting function are accomplished by theselector 357a in cooperation with a single driven member 351a.

FIG. 62 is actually an alternative embodiment which shows the detenting of one of thepawls 364 in recesses or grooves provided by beveling orchamfering 363. FIG. 62 shows one of thewheels 351 as wider than theadjacent wheel 351 to show that theselector 357 in accordance with the invention can work equally well withwheels 351 of different sizes without affecting detenting. With such a construction some of the printingbands 220 can be wider than others as is highly desirable in some applications.

With reference to FIGS. 64 and 65, there is shown another embodiment of a selector generally indicated at 357b. Theselector 357b is the same as theselector 357 in that it has four drive lugs 360b, and a pair ofopposed pawls 364b. Theselector 357b differs from theselector 357 only in that theselector 357 is of one-piece construction and theselector 357b is of two-piece construction. Theselector 357b comprisesbody sections 412 and 413 snap-fitted together. Thebody section 412 has a non-circular hole, and in particular a square hole 414, and thebody section 413 has a correspondingsquare portion 415 received in the hole 414. By this construction, thebody sections 412 and 413 are incapable of rotating relative to each other. Thebody section 413 has four flexibleresilient fingers 416 terminating atprojections 417 shown in FIG. 64 to be received over abead 418. In this position, anannular flange 419 is in abutment with ashoulder 420 on thebody section 412. Theselector 357b is used in the same manner as theselector 357. If desired, theselector 357a (FIG. 63) can be made in two parts as illustrated in FIGS. 64 and 65.

Referring to the embodiment of FIG. 66, there is shown a print head generally indicated at 219c having two spaced-apart sets of printing members .[.220a.]. .Iadd.220c.Iaddend.. Theprint head 219c has two sets of mountingblocks 366c, two sets of driven members 351c andposts 344c, all formed integrally withside plate 335c.Flanges 222c and 223c andgear sections 224c and 225c are spaced apart wider than theflanges 222 and 223 andgear sections 224 and 225. Accordingly, the pair of gears (not shown) which would mesh withgear sections 224c and 225c would have to be spaced apart by a greater distance than thegears 242 and 243. It is also apparent that ball tracks (not shown) which would correspond to the ball tracks 230 and 231 would have to be spaced wider apart, as would be readily apparent to one skilled in the art.Side plate 341c carries aguide member 374c. Theside plate 341c rotatably mounts a pair ofselectors 357c for the respective set of driven members 351c. Theposts 344c mount respectiverectangular sections 371c which provide respective windows 356c. It is readily apparent that with slight modifications theprint head 219c can be operated by a mechanism the same in principle and construction as the mechanism which operates theprint head 219.

Referring to the embodiment of FIGS. 67, 68 and 69, there is provided aselector 357d which is identical to theselector 357. Printing members take the form ofprint wheels 220d. Eachprint wheel 220d is shown to be identical and comprises printingelements 421 carried by anannular hub 422. A mounting anddetenting wheel 423 is shown to be formed integrally with each side of thehub 422. Thewheels 423 have generally annularouter surfaces 424 received insockets 425 of adjacent mountingmembers 426. Thesockets 425 comprise anannular portion 427 and a pair of flexibleresilient arms 428 formed integrally therewith. Accordingly, theprint wheels 220d can be inserted either axially into thesockets 425 or they can be inserted into or removed from therespective sockets 425 by spreadingarms 428. Mountingmembers 426 are provided withrecesses 429 in which offset integrally formed detent pawls orspring fingers 430 and 431 are disposed. Thepawl 430 of one mountingmember 426 is cooperable with notches 430' to effect detenting of anadjacent print wheel 220d on one side of the mountingmember 426, and the other is cooperable with notches 431' to effect detenting of theadjacent print wheel 220d on the other side of the mountingmember 426.

Eachwheel 220d has acentral hole 432, the ends of which are chamfered as indicated at 433. As best shown in FIG. 69,pawls 364d are received in the chamfering betweenadjacent wheels 220d and drivelugs 360d are in driving engagement with theadjacent print wheel 220d. If desired, detenting can be effected in the manner illustrated in the embodiment of FIG. 63.

It is preferred to mold the driver orfeed wheel 244 of a material which incorporates a lubricant to diminish the amount of gum or adhesive that is transferred to thefeed wheel 244 during use to prevent improper feeding. By incorporating the lubricant in thefeed wheel 244 the surface of thefeed wheel 244 has a low coefficient of friction. However, theteeth 249 are adequate to grip and drive theweb 32. One specific material to be used to mold the feed wheel is an acetal resin combined with polytetrafluoroethylene lubricants. One such material is sold commercially under the name Thermocomp, Number KL-4030 by Liquid Nitrogen Processing Corporation, Malvern, Pennsylvania, U.S.A. The remainder of the apparatus in FIGS. 37 through 69 except for theplaten 217, O-rings 282 and 332, theball bearings 228 and 229, thespring 238, thewashers 365, andrubber printing bands 220, are composed of suitable lightweight moldable plastic materials, for example, acetal, acrylonitrile-butadiene-styrene, or the like, but theink roll 311 is preferably constructed of porous vinyl. Accordingly, the apparatus is very light in weight, and easy and convenient to use with a minimum of fatigue.

Other embodiments and modifications of this invention will suggest themselves to those skilled in the art, and all such of these as come within the spirit of this invention are included within its scope as best defined by the appended claims.

In the embodiment of FIG. 70, there is shown acomposite label web30P having groups 38p of cuts at regularly spaced apart intervals. Eachgroup 38p of cuts has a short generally transverse throughcut 500S and a pair of converging throughcuts 501S in the web of supportingmaterial 502. Thecuts 501S are preferably equal in length. The leading ends 503S of thecuts 501S are shown to be in transverse alignment with thetransverse cut 500S. Trailing ends of thecuts 501S are joined at a point orvertex 504S. Thecut 500S and leadingends 503S ofcuts 501S are disposed along a fold line for the respective flap orflap portion 505S. Thecut 505S is shorter than the width of a tooth of the toothed driver, such as thetoothed driver 47e. There arelands 506S at opposite ends of thecut 500S inboard of leading ends 503S.Cuts 500L and 501L are provided through the web oflabel material 507 in alignment withrespective cuts 500S and 501S in the supportingmaterial 502. The cuts 501L are preferably equal in length. Thecuts 500L and 501L in thelabel material web 507 serve to prevent switching oflabels 508 when applied to merchandise. In the embodiment of FIG. 70, it is preferred that eachgroup 38p of cuts be disposed between end edges of thelabels 508 defined bytransverse butt cuts 33p. As in the embodiment of FIGS. 28 and 29, atooth 166 of atoothed driver 47e will engage the supportingmaterial web 502 at the flaps orflap portions 505S and deflect theflap portions 505S out of the plane of theweb 502. Thetooth 166 will engage arespective flap portion 505S at its triangular face and at the fold line between thecut 500S and the leading ends 503S. Thetooth 166 also engages the feed edge provided by thecut 500S. As in the embodiment of FIGS. 28 and 29, thecomposite web 30P is wound into the form of a roll in a direction that the leading ends 503S ofcuts 501S and therespective cut 500S of agroup 38p are at a leading position andrespective flap portion 505S extends away from the leading free end of the roll and toward the trailing end of the roll which typically is adjacent the label core. As theweb 30P is paid out of the roll, theflap portions 505S trail across the delaminator such as 218. As shown in FIGS. 1 and 38 for example, theweb 502 would be engaged by the toothed driver, such as thedriver 47e downstream of the delaminator. An advantage of feeding theweb 30P in this direction is that theflap portions 505S will not deflect out of the plane of the web until theteeth 166 fold theflap portions 505S out of the plane of theweb 502. This advantage of having a trailing flap portion is also inherent in the embodiment of FIGS. 28 and 29. Having flap portions which extend in the leading direction as in the prior art is conductive to the flap portion deflecting out of the plane of the web at the delaminator which results in tearing of the supporting material web. Thecomposite web 30P preferably is made with thecuts 500S and 501S and alignedcuts 500L and 501L extending completely through the supportingmaterial web 502 and thelabel material web 507. This is the same as with the composite webs shown in FIGS. 1 through 33. By this preferred arrangement there is inherently the advantage that the composite web of any of these embodiments including the embodiments of FIGS. 70, 71 and 72, the composite web can be threaded through theapparatus 210 without removing labels from the supporting material web. The tooth of the toothed driver can poke through both the supporting material and the label material web because of the localized weakening provided by the series of flap forming cuts. This poking through of the teeth of the toothed driver can also be achieved when the cuts are only partially through the label material as in the embodiment of FIGS. 34 through 36 but with added resistance from the label material.

The embodiments of FIGS. 71 and 72 offer the advantage of a trailing flap portion as in the embodiments of FIGS. 28 and 29 and of FIG. 70 but the embodiment of FIG. 72 has the advantage that the composite web has greater integrity or strength because of the frangible portions.

In the embodiment of FIG. 71, there is shown acomposite web30Q having groups 38q of cuts at regularly spaced apart intervals. Eachgroup 38q of cuts has a short generallytransverse cut 510S, a pair oflongitudinal cuts 511S and atransverse cut 512S in the web of supportingmaterial 513. The leading ends 514S of thecuts 511S are shown to be in transverse alignment with thetransverse cut 510S. Trailing ends 515S of thecuts 511S are joined in opposite ends of thecut 512S. Thecut 510S and the respective leading ends 514S ofrespective cuts 511S are disposed along a fold line for the flap orflap portion 516S. Thecut 510S is shorter than thecut 512S. There is supporting material on both sides of each cut 510S inboard of the leading ends 514S of thecuts 511S to providelands 517S. Thelands 517S are shown to be equal in width and thecuts 511S are shown to be of equal length.Cuts 510L, 511L and 512L are provided through the web oflabel material 518 in alignment withrespective cuts 510S, 511S and 512S in the supportingmaterial web 513. Thecuts 510L, 511L and 512L in thelabel material web 518 serve to prevent switching oflabels 519 when applied to merchandise. In the embodiment of FIG. 71, it is preferred that eachgroup 38q of cuts be disposed between end edges of thelabels 519 defined by transverse butt cuts 33q. As in the embodiment of FIGS. 28 and 29, and FIG. 70, atooth 166 of atoothed driver 47e will engage the supportingmaterial web 513 at the flaps orflap portions 516S and deflect theflap portions 516S out of the plane of theweb 513. Thetooth 166 will engage arespective flap portion 516S at its rectangular face and at the fold line between thecut 510S and the leading ends 514S of thecuts 511S. Thetooth 166 also engages the feed edge provided by thecut 510S. As in the embodiment of FIGS. 28 and 29, thecomposite web 30Q is wound into the form of a roll in a direction that the leading ends 514S ofcuts 511S and therespective cut 510S of agroup 38q are at a leading position in the web and therespective flap portion 516S extends away from the leading free end of the roll and toward the trailing end of the roll which typically is adjacent the label core. As theweb 30P is paid out of the roll, theflap portions 516S trail across thedelaminator 218. Theweb 513 would be engaged by the toothed driver such as thedriver 47e downstream of the delaminator.

The embodiment of FIG. 72 is identical in construction and use to the embodiment of FIG. 71 except thatcomposite web 30R has groups .[.38.]. .Iadd.38r .Iaddend.of cuts withfrangible portions 520S and 520L. Theweb 30R has throughcuts 521S, 522S, 523S and 524S in the supportingmaterial 525 and aligned throughcuts 521L, 522L.[...]..Iadd., .Iaddend.523L and 524L in thelabel material 526. Thecuts 521L, 522L, 523L and 524L can be made only partially through thelabel material web 526 if desired as in the embodiment of FIGS. 34 through 36. Theland 520S is much shorter thanrespective lands 527S so that theland 520S will always be severed by thetooth 166 and so that thelands 527S will not be severed. Theweb 30R is wound the same way as the webs of the embodiments of FIGS. 28 and 29, 70 and 71 so that flaps orflap portions 528S trail across thedelaminator 218 and so that both the feed edge formed by thecut 521S and by the respective fold line are engaged by thetooth 166. If desired,butt cuts 33r can be made betweengroups 38r as shown. Because of thefrangible portions 520L thebutt cuts 33r can be made transversely across thelabel material web 526 throughcuts 522L betweencuts 521L andcuts 523L and 524L.

Other embodiments and modifications of this invention will suggest themselves to those skilled in the art, and all such of these as come within the spirit of this invention are included within its scope as best defined by the appended claims.
