My invention relates toa paper article simulating for example, a handkerchief or a towel or thelike, and a process of producing the same. This application is in part a con- '5 tinuation of my previous application No.

' Paper handkerchiefs for example, have been produced heretofore but they are relatively harsh and scratchy and have neither the appearance nor the softness of a used fabric handkerchief. One of my ob jects is to produce a only closely simulates the appearance, but
in particular has the soft feel, of a linen or cotton handkerchief which has been used and laundered several times.
I A further. object of the invention is to provide a high degree of absorbency in the article by usingfor the individual layers cellulose tissue of such light and flimsy construction that moisture is readily absorbed through the interstices of the fibre construction and also through adhesion between the layers. It is also possible by my process closely to simulate other fabric articles such as napkins, towels, tablecloths and rolls of cloth for toilet use.
I am aware that my invention may be embodied in various forms, but for the purpose of illustration merely I have herein shown and described the production of a paper handkerchiefas one embodiment of the invention.
In the drawings- Fig. 1 represents a view of oneof my handkerchiefs;
Fig. 2 an enlarged corner. I
Fig. 3 a still further enlarged section on the line 3-3 of Fig. 2; and
Fig. 4 is a diagrammatic representation of a machine which may be utilized to carrv out my process.
- Mv handkerchief consists essentially of a plurality of superposed sheets of soft absorbent cellulose tissue, such for example, as
facial tissue used extensively for the application to and removal from the skin of various cosmetics such as cold cream, rouge and the like. It is of course fibrous and soft, but in the single sheet has neither the strength,
' trated in the drawings, I have shown three handkerchief which not appearance, absorbent qualities nor feel of a used fabric handkerchief. Of course there may be as many superposedsheets as desired. In the embodimentillussuch sheets 1, 2 and 3.
They are fastened together by pressure exerted over a narrow strip at each margin as indicated at 4 and 11, the pressure being sufficient to somewhat interlace the fibres. They may be relatively dry when pressed, or may be dampened if desired.' No adhesive need be used, as the pressure alone will cause the sheets to adhere sufiiciently. This simulates the appearance and feel of the hem of a handkerchief.
In order more closely to simulate the appearance of a cloth'handkerchief and to obtain a further mechanical advantage I prefer to form lines of indentations along the inner margins of each of the pressed areas, as indlcated at 5, 8, 12 and 10. These indentations preferably perforate the sheets as indicated at 6 in Fig. 3. They not only simu-- late lines of stitching but also serve addi-' tionally to fasten the sheets together as the material of one sheet is carried through the o her sheets.
- The portions of the sheets within the pressed areas or the lines of indentations are not fastened together but are left so that they may move slightly one .upon the other to give the soft feel of'a well-used fabric handkerchief. I prefer to emboss the sheets substantially throughout at least the entire area bounded by the compressed portions, such as by slightly creping the material as indicated by the wavy lines in Fig. 3 of the twoouter sheets 1, 2. This is particularly an advantage because it increases the stretchability and heightens the soft feeling, for when pressed between the fingers the layers yield somewhat with relation to each other. Of course instead of creping, other forms of embossing may be used such for example as embossing to simulate the appearance of a woven fabric or of damask linen. It is alsoeasy to simulate an embroidered initial, or monogram by suitably embossing only one of the outer sheets if desider. In fact the appearance of the article The sheets should be movable upon-one another to a slight extent. In some cases it is desirable to have the twoouter sheets 1, 2,
creped and the inner one or ones substantially plain-faced as indicated at 3 in Fig. 3.
Of course the different sheets forming the handkerchief may be cut out in the size of'the finished handkerchief and suitably pressed and indented, all in one operation. It is however desirable to manufacture them by a continuous process in which they are produced first in the form of a continuous endless strip which then may be'severedor broken into the individual articles. This is particularly desirable if one wishes to obtain the same softness, absorbent qualities and appearance of fabric in a continuous strip of imitation towelling for example.
Fig. 4 represents diagrammatically a machine which may be used to carry out my process. 1*, 2 and 3 indicate three rolls ofpaper strips 1, 2 and 3 of the character above specified, l and 2 being creped (although not so shown in this figure) transversely of the strip, while 3 represents a substantially fiatfaced sheet, as indicated in Fig. 3, of substantially moisture-proof paper. These strips may be superposed by passing them over aroller 13. The edges are then heavily pressed in any suitable way, such for example, as by passing them between a pair ofrollers 14, 15 at each side, theroller 14 preferably being covered with soft rubber. The three sheets will therefore be fastened together at their edges by the pressure.
The strip is then at the desired intervals pressed transversely across in any suitable way such as by asegmental roller 16 which presses the strip between it and theroller 17 so as to form a transverse compressed area as indicated at 18. In case square handkerchiefs are to be formed this transverse pressed area would be twice the width of the hem 7 of Fig. 1. The lines ofindentations 5, 12 along the inner margins of the compressed areas 4, 11 at the sides of the sheet may be formed by suitable indenting wheels such as indicated at 19, 20. The transverse lines ofindentations 8, 10 may be formed by 21.segmental roller 21 provided with a double row ofpins 22, 23. 24, 25 represent rotary trimmin g knives.
The strip is thus formed into a series of handkerchief-like portions which are still integrally joined. If it is desired to separate them into individual handkerchiefs, the strip may be cut across each transverse compressed portion, as for example, on the line indicated by mm, by means of a suitable knife.
If, however, it is desired to use the strip in the manner toilet paper is used, or for towelifrvness ing at wa shstands, it may be made up into a roll from which each individual square or section maybe torn off at the desire of the user. The transverse pressure or indentations of course form, or may be made to form, lines of weakness by which one section or handkerchief portion may be easily torn off from the next one.
I am aware that my invention may be embodied in various forms and may be produced by mechanism which differs widely from that of the embodiment shown in Fig. 4. I therefore do not intend to limit myself to the particular article or mechanism or steps of the process herein disclosed, as these are merely illustrative examples of my invention.
What I claim is:
1. A plurality of superposed sheets of soft cellulose tissue compressed together in a. narrow strip entirely around the edges so as to cause the sheets to adhere at those portions but elsewhere to be movable one on the other.
2. A- plurality of superposed sheets of soft cellulose tissue compressed together in a narrow strip entirely around the edges so as to cause the sheets to adhere at those portions but elsewhere to be movable-one on the other, together with lines of indentations along the inner margins of the pressed areas.
3. A plurality of superposed sheets of soft cellulose tissue of soft and flimsy construc: tion such as facial tissue compressed together in a narrow strip entirely around the edges so as to cause. the sheets to adhere at those portions but elsewhere to be movable one on the other, at least one exterior sheet being embossed substantially throughout the area bounded by the portions so compressed.
4. A plurality of superposed sheets of soft cellulose tissue compressed together in a narrow strip entirely around the edges so as to cause the sheets to adhere at those por tions but elsewhere to be movable one on the other,-the exterior sheets being creped substantially throughout the area bounded by the portions so compressed.
5. A continuous strip of paper comprising a plurality of superposed strips of soft tissue paper pressed together along their edges but movable on each other within the areas bounded by the portions so pressed, and having a weakened line across the strip at intervals which also fastens the sheets together along that line.
6. A process which comprises superposing continuous strips of soft tissue paper and pressing them along their edges and also' transversely across the strips at intervals, causing the strips to adhere along the pressed portions but allowing the same elsewhere to move on each other.
7. A process which comprises superposing continuous strips of soft tissue paper and pressing them along their edges and also transversely across the strips at-inter'vals,
