To all whom z't may concern.'

Be it ln/iown that I, JOHN C. FQGABTY, citizen of the United States, resldmg at Green Bay, in the county of Brown and,

State of Wisconsin, have invented a certain new and useful Improvement in Machines for Slitting, Perforating, and Rewinding Paper, of which the following is a full, clear, concise, and exact description.

My invention relates to improvements 1n machines for unwinding paper from a large, wide roll and slitting, perforating and rewinding the same on a plurality of smaller narrower rolls.

The object of my invention is to provide improved mechanism whereby these operations, which have heretofore been somewhat intermittent and have required hand labor to a greater or less extent, may be carried on continuously and substantially automaticall Ays contributory toward carrying out this general object, I have, as further objects of my invention: To provide a machine having a rotary frame on which the cores for the smaller rolls may be carried in different groups in such manner that while one group of rolls is winding, a completely wound group may be removed by an attendant and a third group of cores may be pasted as a preliminary to the winding operation. To provide a machine having means for moving the groups of cores into and out of operative relation to the rest of the machinewithout stopping the latter. To provide a machine having improved perforating means; and to provide amachine of increased and greater eiciency and reliability.

In the accompanying drawings I have illustrated a. machine which embodies my invention, which latter, however, may be embodied in other forms. Y

Figure 1 is a side elevation of a machine constituting the preferred embodiment of the invention; Fig. 2 isa front elevation thereof; Fig. 3 is a sectional elevation onythe line 3 3 of Fig. 2; Fig. 4 is an enlarged elevation of one of the rollers; Fig. 5 is a transverse section thereof showing the relation of the perforating and slitting knives thereto. Fig. 6 is an enlarged, sectional ele' vation of the pasting trough and paste-applying rolls; Fig. 7 is an enlarged side elevation of the knives for severing the paper and associated mechanism; Fig. 8 is an ensimplicity'` larged side elevation of the rotatable frame which carries the cores; and Fig. 9 is a central sectional elevation of -a frictionally driven socket member. Y l

The machine is provided with asuitable frame 1 which carries the various parts of the mechanism. A large roll ofpaper 2 is mounted preferably at the rear end thereof, said roll being supported on ashaft 3 mountedin suitable bearings in the frame and having an enlargement orcollar 4 at one end thereof. Aband brake 5 surrounds the said collar, the ends thereof being suitably adjusted by a screw-threadedrod 6 extending to the forward part of the machine,

whereby the operator may vary the friction developed while' the roll is unwinding to maintain nearly uniform tension on the web or sheet of paper. The paper is unwound in a thin,wide sheet 7 which is fedpast rollers 8, 9 and 10, passing underrollers 8 and 10 and over roller 9 as shown in Fig. 1, during which passage it is slitted into a plurality of narrow parallel bands and then rewound in a plurality of small rolls 11 aboutsuitable cardboard cores 12. As soon as the small rolls have attained the desired diameter the narrow bands of paper are cut by a suitable mechanism, hereinafter described, the ends of said bands being pasted to a new set of cores and the winding continued without interruption, while the completed rolls are being removed.

The machine derives its power preferably from a belt 13 which rotates a pulley 14, the latter being adapted, by means of asuitable clutch 15, to rotate ashaft 16, the latter being the shaft on which the roller 9 is mounted. Apulley 17 is mounted on the other end of said shaft and carries a belt 18 which drives anotherpulley 19 mounted on ashaft 20 arranged transversely at the forward part of the machine.l A-pulley 21, mounted on one end of said shaft, drives abelt 22 and hence asecond pulley 23, which latter rotates ashaft 24 on which thepasting rollers 25 are mounted. Theshaft 20 also carries a-nadditional pulley 26 which drives abelt 27, the latter passing over a pluralityof pulleys and serving to rotate the re-winding rolls as hereinafter described. The cores of said rolls are mounted onsuitable shafts 28` 29, 30, all of which are alike and are re. movably supported at opposite ends, in suitable sockets carried at the outer ends ofradial arms 31. The cores are round, whereas the shafts are perfectly square, said cores being sprung slightly to maintain a frictional hold on the shafts which rotate them. Theregare a plurality of arms at each side of the machine, preferably three, formed integrally to provide a rotating frame as shown in Fig. 8. Said frame may be rotated by hand to move a series or line of small rolls out of operative relation with the rest of the machine when the rolls have attained the desired diameter, thereby automatically bringing the next set of cores into line for the winding operation.

The preferred construction for the sockets and associated parts on the rotating frames is shown in Fig. 9. Ashaft socket 32 is received within an opening in each arm, which socket is adapted to receive non-rotatably the end of any one of theshafts 28, 29 or 30. This shaft` socket extends through asleeve 33, which latter carries agrooved pulley 34. A ring orwasher 35 offriction material, suchras leather for example, is interposed between said pulley and a washer 36, the latter having ahollow hub 37 containing aspring 38.' Apin 39 passes through elongated slots in saidhub 37 and serves to maintain the parts in frictional engagement. The spring is held in place by a suitable screw-threaded cap 40. When the pulley is rotating, it drives the socket shaft through the friction of the coperating parts, which friction may be varied by a sliding ring41 which exerts pressure against the hub of the grooved pulley, the pressure being varied by a knurled nut 42. This adjustment determines the degree of tightness with which the paper is wound.

Therotatin frames 31 are supported on asuitable sha t 43 journaled in the forward part of the frame. Said shaft supports also an arm or lever-44 which carries agrooved pulley 45, the position of the latter vbeing adjustable through a small arc by means of thelever 44, which latter may be locked in any one of a number of angular positions by means of thelatch mechanism 46, 47 and notched section 48. Thebelt 27 previously described is driven by thepulley 26 and passes over thepulley 45 and also over one of thepulleys 34. It passes also over a spring actuated belt-tightening pulley 49. When the parts' are in the position shown in Fig. 8, it will be seen that only the upperleft hand pulley 34 is rotated by thebelt 27, the other two pulleys being idle. Accordingly the paper is rewound on the cores carr-ied on the uppermost shaft farthest to the rear. When the small rolls have attained the desired diameter theshaft 43 is given a third of a turn by an attendant who operates the hand-wheel 50 shown in Fig. 2, the

pulley' 45, during this turning movement,

remaining in the position shown in Fig. 8.

The rotation of theshaft 43movesthe shaft 28 forwardly, during which movement the narrow bands of paper are severed as hereinafter described, the lowerlnost shaft 29r being simultaneously swung up to the winding position. The cores on said shaft have had the necessary paste applied thereto by the pasting rolls 25, which rotate in the paste contained in thetrough 51, and accordingly the advancing bands of paper tend to adhere to the cores and do adhere and begin to wind thereon as soon as the paper is severed. As a result the winding proceeds continuously, the operator smoothing down the free ends of the paper on the fully wound rolls, which ends have picked up a small amount of paste prior to being severed, whereby said ends adhere immediately to the rolls and no loose ends are left. To aid in this smoothing down operation, the operator may move thehandle 44 downwardly about as shown in dotted lines in' Fig. 8, whereby thebelt 27 may be brought in contact with the right hand groovedpulley 34, thereby frictionally driving the latter and continuing the rotation of the full rolls for a short interval. Although the operation of the machine is not interrupted during the above described operations, it is desirable to slacken the speed thereof if run# ning at high speed, either by manual operation or automatically. As soon as the finished rolls have been smoothed down, the' operator removes the shaft on which thev are supported from the rotating frame, and after removing said rolls from said shaft, slips a new series ofcardboard cores 12 thereon.

The saw-tooth cutting knives 52 are carried onarms 53 pivotally supported onbrackets 54, the latter being rotatably mounted on ashaft 55. A weight 56 (or its equivalent, a spring) is used in coperation with adrum 57 to counterbalance the weight of the knives and supporting arms therefor,

whereby said knives may be moved up and down readily to cut the paper, which operation may be either manual or automatic. Thearm 53 carries aroller 58 which serves to hold down the free ends of the narrow bands of paper against the pasted core to insure the beginning of the winding operation. springs 59 which press the paper' against said cores. Thearm 53 is normally held in the position shown, against a suitable stop, by means of aspring 60, the pivotal connection between thearms 53 and 54, however, permitting the knives to move forwardly at the time they cut the traveling bands of paper, thereby avoiding tearing the paper. Said knives are also permitted, by this arrangement, to press against the cores. The perforatingknives 61 are of the customary form, and are rotated in timed relation to This action is also aided by the the roll 9, whereby they are made to drop intosuitable recesses 62 in the roll 9. As the paper advances, it is slitted by suitable slittingknives 63 which are preferably spaced apart equal distances along a shaft G4, the latter being journaled in a frame or cap 65 which is pivoted at 66, whereby said knives and other parts hereinbefore described may be lifted when it is desired to thread the paper through as in starting up the machine or inserting a new roll of paper to be unwound. Movement is imparted to the frame 65 bv a suitable cam-lever 67, the operation of which is indicated by dotted lines in Fig. 3. The slitting knives rotate ingrooves 68 in the roller 9, as shown in Fig. 4 to insure their passing through the paper while at the same time providing a suitable clearance.

In prior machines with which I am familiar, it has been necessary to stop the machine when the small rolls were completed, remove the supporting shaft and substitute a new one with cores in place. The end of the paper was then pasted down by the use of a brush, smoothed down by hand on the core and the machine again started. During the time of making this change, the machines are idle and a great deal ofthe attendants time is wasted. By the employment of the mechanism described herein, practically all of the operations are automatic and continuous as a result of which the output can be more than double as compared with results formerly obtained.

W'hile I have described the preferred embodiment of my invention, I do not desire to limit myself to the details thereof, as various other forms may be devised which fall within the scope of the appended claims.
