To all whom it may concern:

Be it known that I, RICHARD A. Wnissn,

a citizen of Germany, residing atBrooklyn, countyof Kings, and State of New York,

have invented a new and Improved Machine for Folding and Cutting Textile and Paper Strips, of which the following is a specificajtion. This invention relates to a machine of novel construction for folding textile and paper strips and for cutting them up into pocket book gussets, index tabs or similar articles. 1 Briefly stated the machine comprises a pair of folders of which the first folder is adapted to turn over the two longitudinal edges of the strip to form a pair-of flanges, while the second folder is adapted to double the flanged strip upon itself. The strip-is drawn through the folders by means of a pair of feed rolls placed in advance thereof, while acutter placed, in turn, in front of the feed rolls, cuts up the folded strip into the lengths desired. The feed rolls and cutter are operated fromthe power shaft by means of a transmission, which actuat'es the same alternately, so that the strip will be at rest while being out. I

In the accompanying drawing:'Figure 1 is a plan of a folding and cutting machine embodying my invention; Fig. 2 a side elevation thereof; Fig. 3 a face View of the strip-edge folder; Fig. 1 a'longitudinal-section on line 4l1, Fig. 3; Fig; 5. a face View of the strip-doubling folder; Fig. 6 a longitudinal section on line 66,' Fig. 5; Fig. 7 a cross section on line 77, ,Fig."3;'*Fig. 8 a cross sect-ion on line 8-8, Fig. 5; Fig. 9 a perspective view ofa gusset formed by the machine, and Fig. 10 a perspective view of a similarly formed index tab. 7

From the base plate 10 of the. machine frame extends an upright spindle 11, upon which is'free to turn a spider 12' that supports the roll 13 of a paper or textile strip ortape 14. This strip is carried around a pair of "guide pins 15, 16 extending up- From pin 16, strip 141s carried through a substantially horizontal position.

the first folder A, and thence throughthe "second folder B, by means ofapair of feed rolls 22, 23 placed" in advance of folder B, andwhich will be referred tomorefiilly later on. Y J

The first folder A is composed of a-plate 24 placed edgewise and provided, at its outer side with an eye or hub 25, which loose1y encompasses a spindle 26 that extends u wardly from an arm 27 bolted to plate 10 at 28. The top and bottom edges of plate 24 are turned over more-and more from the receiving or rear end toward the 'delivery or front end of the folder, so that there are formed a pair of graduallywidenin'g vertically disposedlongitudinal flanges 29 while the body of the (plate is correspondingly ta peredor reduce At the receiving endfof the folder, there is furthermore secured to "plate 21 a cross bar 30,to form a Hat eye through which the strip 141 is threaded;- A

- further provided at. those'points where-the flanges 29 take a f 'ironounced turn, while an additional pair 0 inwardly extending guide lugs 32 is provided at the forward end of These lugs 32ers made integral with a flat resilient bar 33 attached to plate 24 stat, softhat there'is provided a certain la between plate and lugs. From the E y of cross bar 30, there is stamped out a-hook 35 that engages the slitte'd heel 36 of a flat tongue 37. This tongue faces the operative or flanged inner side of plate 24 toward which it is held by lugs 31, 32, and thus presses'strip 14 tightly a ainst such plate. The free end of tongue 3 is straddled: by the flanges 29 and is longitudinally slotted as at 38 to increase its flexibility. As the strip 14 is' drawn through the folder, its longitudinal edges will be gradually upset by the taper of plate 2 1 and flan es. 29 against the exposed side'of tongue 3 so as to form the desired edge flanges 39 upon the fabric strip, in which condition the latter is delivered to the second folder B.

The second folder is composed of a plate 40 having at its inner side an eye orhub 41 which is free to turn loosely on a spindle 4 ;2 that extends upwardly from an arm 43 bolt 'ed to plate 10-at 44:. Plate, 40, isgradually. bent or doubled upon itself from its rear toward its front end to form a pair of jaws 4-5, which conver e from the rear toward the front, at'whicll latter point they assume pair-of inwardly extending guide liigs31 are plate 24; directly in front of flanges 29.

By the construction described, plate 40 is made substantially of trough-shape, the ngress end of the trough being provided with an upright guide bar 46 forming an eye for strip14, while the egress end the trough is provided with a horizontal guide eye 47 encompassing the ends of aws 45. In order to hold strip 14 tightly against the outer concave operative side of the trough, bar 46 carries a tongue 48 which cooperates with a air of doubled spring fingers 49, between w 'ch the ti of the tongue projects. It will be seen t at as the stri received from folder Ais drawn through older B, it will be doubled upon itself along its longitudinal axis, as at 50, Fi .9 to assume the gusset shape desired. I the first folder A be removed from its spindle and the second folder B only be used, then the strip will .not be provided with end flanges, but only with the central fold as indicated at 50 Fig. 10. Thus it will be seen that the machine is adapted to fold the strips either thrice or once only, the former adjustment, being used for making say pocket book gussets, while the latter adjustment is used for making say reinforcin finger pieces or index tabs for blank boo s, etc. It may here be added that by pivotally mounting the folders upon the mac ine bed, they will be automatically swung into a true position by means of the pull exercised upon the strip 14 by the feed rollers, so that their proper alinement is at all times assured. So also by the peculiar construction of the folders, those doubled portions of the strip which occur from time to time, wherever the end of one strip unit is pasted over the correspondin end of the succeeding strip unit, will pass reely underneath the root of the tongues and the yielding lugs 32, so that they will not interfere in any wise with the free operation of the machine.

As has been stated, the feed rolls 22, '23

are located directly in advance of the second.

folder B. The stud 51 of lower roll 23 is mounted in an arm 52 which is pivoted .at 5.3 to a standard 54 and has an extension 55 enga ed by a set'screw 56. Between arm 52 and ase plate 10, is interposed a coiled spring57, the tension of which is thus regulable by the set screw, and which serves to press roll 23 against the driven upper roll 22. The means for impartingintermittent movement to roll 22, comprise a power shaft 58 journaled in a standard 59 and adapted to be coupled to a pinion 60 by means of a clutch 61, said clutch being operated by a hand lever 62 adapted to be locked by latch 63. Pinion 60 meshes into a large gear wheel 64, to the outer face of which the rear end of a driving rod 65 is connected by wrist pin 66 and slide 67, so that in this way the stroke of the rod is regulable. The-forward end of rod 65 engages an oscillativearm 68 loosely turning on a shaft 69 and provided with a pair of pawls 70. These pawls engage a ratchet disk 71 fast on one face of a toothed wheel 72 that is intergeared with a pinion 73 turning on the stud 74 of roll 22, said pinion being rigid with said roll. This pinion is connected to a toothed wheel. 75 of said roll which is intergeared with a corresponding wheel 76 of lower, roll 23. Itwill be seen that by the construction described, the forward stroke of rod 65 will by pawls 7 O and ratchet disk 71 impart the desired feed movement to rolls 22, 23, while during the back stroke of the rod, the pawls will ride idly over said disk, so that in this way the movement of the rolls is rendered intermittent in the manner desired.

In advance of the feed rolls, there is provided a guide'or eye 77 for strip 14, while in advance of this guide, there is provided acutter for dividing the strip into. the lengths desired. This cutter may be either straight or it maybe differently shaped to accord with the shape to be given to the severed strip-lengths, a curved cutter being for example used for cutting the lengths shown in Fig. 10. The upper movable cutting blade 78vis fitted to a head 79 rocking on a shaft 80, which is journaled in a block 81, said block constituting likewise a support for the guide 77 as Well as for the fixed cutting blade 82 that cocperates with the movable blade 78. Head 79 is normally swung'up by means of a coiled spring 83 fitted upon 7 shaft 80 and engaging with one end a disk 84 fast on the shaft and with its other end a hub 85 integral with head '7 9. From this hub, there extends a tappet 86 engaging the forward arm 87v of a two arm lever which lever is fulcrumed at 88. The rear arm 89 of this lever is adapted to be engaged by a pin 90 projecting from the inner face of wheel .64,-some distance back of wrist pin 66. Thus it will be seen that when rod 65 performs its back stroke and rolls 22, 28 are consequently at rest, the rear lever'arm 89 will by pin 90 be depressed to. correspondingly tilt cutter-head 79 downward by the engagement of front lever arm- 87 with tap pet 86. In this way, the knife 78 is swung down against the action of spring 83 to sever the desired section off strip 14, after which the knife is immediately swung up by spring 83, which comes into action as soon as the pin 90 has cleared the lever.

It will be seen that the machine constructed as described will fold and cut the strips into gussets, tabs orsimilar articles, in a quick, accurate and workmanlike manner.
