33 Claims.

This invention relates to a machine for assembling sheet material and has for one of its objects a mechanical formation and assembling lof several plies of material and attaching the same together to provide an article such as a pad used for permanent hair waving.

Another object of the invention is the utilizing of one web of paper fo forming a. plurality of the plies of material to be assembled by folding the l0 web of paper.

Another object of the invention is the provision of a device for mechanically assembling sheets of material by feeding the material continuously without interruption through the machine in order that the production-ofthe machine may be increased.

Another object of the invention is to continuously feed one of the webs of material through the machine and intermittently feed other webs of material into the desired relation with this web, and to cut off these other webs without interruption of the feed.

Another object of the invention is the proper positioning of the different plies of material prior to their attachment together.

Another object of the invention is the provision of a sewing attachment which will sew the plies of material into assembled relation while in continuous passage through the machine.

A further object of the invention is the printing of the finished assembly while continuously passing through the machine and without stopping the same.

With these and other objects-in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

Referring to the drawings, this machine may be used for the assembly of various materials and for illustrative purposes I am showing a permanent hair waving pad as one illustration of an article which this machine can produce.

This pad as illustrated in Figs. 15 and 16 shows a ply of tinfoil 20 with a web of paper folded as at 2| to provide a ply 22 and a ply 23 of paper 30 on either side thereof. There is inserted between these

plies

22 and 23 .at their free edges a ply of material 24 of flannel and the entire assembly is stitched together by a line of stitching 25 as will be clearly indicated in these views Figs. A15 and 16.

In order that the general scheme of procedure may be understood before the details of the machine are described, I will refer to Fig. 8 which illustrates a reel 26 of a web of paper 21 which is drawnv from the reel by feed rolls 28 and 29 through a folding device 30 which is assisted by a double taper roller 3| which also guides the paper at the start of its folding movement. As this web of paper is continuously fed by rolls 28 45 and 29 a web of tinfoil 32 is drawn from the reel 33 intermittently by roll 34 and its companion roll 35 and inserted between the folded web of paper after which it is severed by a cutterv 36 and pinched and fed forward by the companion 50 rolls 31 above and 38 beneath which intermittently grip and feed it forward. A web of flannel 39 is fed intermittently from a reel 40 by rolls 4I above and 42 beneath to position the end of the flannel just inside o f the free edges of the folded 55 paper after which the annel is cut oi! by a cutter knife 48 and then the flannel isgripped and fed forwardly by the intermittently acting feed rolls 44 above and 4l beneath to position the work under the needle 48, which performs the sewing operation, while the parts are travelling through the machine, being drawn continuously through all of the operations by the

cylindrical feed rolls

28 and 28.

At certain intervals, between the portions of tinfoil and feit inserted, the cutter knife 41 will operate to cut the web of material or paper after which it will be picked up by the roll of the printing press 48 and fed out of the machine at which time the printing will take place.

The operation of the mechanism which I have described will be more fully hereinafter explained. 'I'he bed of the machine, designated 88, see Fig. 2,

' is supported from the iioor by a suitable framework II 'having legs 52. There is bolted onto this framework II an angle iron 58 which extends several feet beyond the bed of the machine and is provided with a spindle 54 to suitably support the roll28 of the main web of paper. An angle iron Il is also supported by the framework and bed of the machine to extend at right angles to the angle iron 88 and provides a suitable support for shaft I8 upon which the rolls 88 and 48 for the tinfoil and flannel are mounted.

An electric motor 51, see Fig. 3, is mounted on a platform 59 supported from the bed 90 of the machine by hangers 58. This motor drives a pulley 88 through a friction clutch 8| operated by a bell crank lever 82 having an arm 88 and handle 94 urged in one direction by a spring 8l to disconnect the clutch from this pulley 88. Power is transmitted by the belt 88 to the pulley 81 on the shaft 68 of the machine, which directly drives the sewing mechanism of my machine. From this shaft 8l power is transmitted to the mainshaft 69 of my machine by suitable gearing housed within the compartment 18. Atone end of the shaft 89 there is provided a spiral gear 1| meshing with spiral gear 12 to transmit power to the cross shaft 18 of the machine which extends at right angles to the main shaft 89.

'Ihe main feed roll 28, see Figs. 1 and 4, is driven from the.cross shaft 18 through a train of gears 14, 11, 18, and 18. shaft 1l, and train of

gears

18, 89 and 8|, the latter being mounted upon the shaft 82 upon winch roll 28 is mounted. This gear 8| also drives the shaft 88 for the lower roll 29 by means of the gear 84 mounted on this shaft and meshing with gear 8|.

'Ihe upper roll 28 and its gear are mounted in a bracket 89 which tends to be moved upwardly out of mesh with the gearing by a spring 88 and is moved downwardly by a screw 81 operated by a knurled linger piece 88 acting through a suitable arm 89 on the framework 99 for the gearing shown.

Above4 the cross shaft 18 there is mounted a short shaft 9|, see Figs. 2 and 3, which is driven from the cross shaft 18 through gear 92 mounted on the cross shaft 18 and gear 98 mounted on the shaft 9|. Upon this shaft 9|, there is mounted a spiral gear 94 for driving the upper feed roll 84 which moves the tinfoil into position, the lower roll 85 being a cylindrical rubber roll and not driven. The rolls 84 are suitably supported on shafts 88 and 91 mounted in suitable bearings. 'I'here is also a similar feed mechanism for the nannel consisting of a spiral gear 98 on the shaft 8| which drives a spiral gear 99 on shaft |88 for driving the feed roll 4I while the lower roll 42 is cylindrical and of resilient material such as rubber. 'Ihis shaft |88, and the similar shaft I8| for the cylindrical roll are suitably supported in bearings provided above the bedof the machin e. Y A cutter 88 for the oil, see Figs. 1 and 2, is mounted upon an arm I 2 which is secured to the shaft |88 mounted in bearing |84 for rotation about its axis by arm |88 locked thereto by a pin. 'I'his cutter is moved towards the fixed cutting edge with which it cooperates by spring |88. 'l'here is also similarly arranged for the flannel web a cutter 48 which is mounted on arm |81 secured to shaft |88 extending through bearing |88 and having an arm III locked `thereto by a pin. This cutter 48 is moved towards itsy fixed cooperating edge by a spring I. Each of these arms |99 and ||8 is provided with extensions ||2 and I|8 to be respectively engaged by cams |I4 and IIB mounted on cross shaft 18 for swinging these arms to operate the cutters 88 and 43. These arms are raised to raise the cutters by springs |I8 and II1 which act to maintain the lateral portions ||2 and ||8 in the path of movement of these cams.

' `A folder for guiding the web of material21 is mounted upon an extension arm |28, seeFig. 9, suitably secured to the bed of the machine or the framework thereof.y This extension arm ,|25

' supports post |28 which carries an arm |21 for suitably supporting the folder 88. 'Ihis folder consists preferably of a sheet of metal |28 doubled upon itself as at |28 in substantially a u-form with flaring edges |88 while the inside of the folder consists of another strip of sheet metal |8|` doubled upon itself as at |82 with flaring edges |88 bent over and secured to the flaring edges |80 as at |84, the arrangement being such as to leave a space |88 or U-shaped passage between these inner and outer parts. The inner part designated generally |8I is of greater extent than the outer part |28 as will be illustrated by the dotted lines in Fig. 8, the extent being such that the end |88 of this inner part will be adjacent the cutter 88 which severs the tinfoil so that as the paper 21 is fed through the folder and emerges therefrom, the edges will be spaced apart by reason ofthe guide |88 and the upper edge will engage the cutter 88. as iliustrated at |81, in Fig. 12, to hold this upper part outwardly so that the web of tinfoil 82 will be assured of entry between the folded plies of the web 21, such as illustrated in Fig. 12.

'Ihis web of tinfoil is fed forwardly by the rolls 84 and 85 'which are rubber rolls shaped as illustrated in Fig. 14. The feeding surface |40 of the upper roll is of a length which it is desired that the tinfoil shall be fed forwardly and the vremainder of the surface |4I is cut away,v while the lower roll is cylindrical as shown. 'I'he upper roll rotates continuously while the lower roll only rotates when the tinly a distance equal to the surface |48 of these rolls. The tinfoil is drawn from'its reel and fed in and out about the vtension bars |42 and |48 and beneath the cutter 88, and the tinfoil is fed into the open edge of the web of paper 21, as illustrated in Fig. l2, while this paper is foil is gripped intermittently and fedl forward in motion. As soon as the feed of the tinfoil is completed the cutter quickly acts longitudinally of the ,travel of the web of paper 21 to cut oif this foil as it is travelling with the web 21. As the foil reaches the inside fold of the web 21, it is gripped by the auxiliary feed rolls 31 and 38 which areshaped as illustrated in Figs. and 6 with both of their engaging surfaces such as |40 so arranged as to grip the fold with the tinfoil therein after it has completed its feed and Will thus bind the tinfoil during the cutting action of the cutter 36 as well as assist it to be fed forwardly with the web of folded paper 21.

As the web of folded paper 21 with the tinfoil assembled therein approaches the line of feed of the flannel web 39, the paper web is spread apart by a guide member |45, illustrated most,

clearly in Fig. 13. 'I'his guide member |45 is a strip of sheet material having a bottom layer |46 bent as at |41 to provide doubled over portions I 48 having upwardly turned projections |49. This guide is positioned between two plies of the material 21 and so located as to be above the tinfoil which has been inserted in position. The guide member will open the two folds of the doubled paper 21 for the reception of the flannel 39 which is to be inserted therein.

'Ihis flannel is drawn from its reel 40 over tension bars |50 by the rolls 4| and 42 which are shaped similarly to the diagrammatic layout in Fig. 14providing an. engaging surface |40 to feed the felt the desired amount forwardly so that its end enters beneath the marginal edges of the folded strip of web 21 and is limited in its movement in this direction by the fold |41 of the guide member |45. As soon as this forward movement of the felt or annel is cornpleted the cutter 43 descends to sever a piece of felt which will be designated |5| from itsweb and at the time of severing and at the end of the forward feed of this flannel web the same is gripped by the continuously rotating altho intermittently gripping feed rolls 44 and 45 which are shaped similarly to the layout in Fig. 6, to feed this flannel forwardly'and beneath the needle |52 of the sewing machine, which needle is mounted irl-a reciprocating bar |53, it being understood that the rolls 44 and 45 feed the flannel at substantially the same rate as the web of folded paper is fed forwardly by the main feed rolls 28 and 29.

At the upper end of the needle bar a strap |62 is fixed thereto and embraces a standard |63 which is oset at its upper end as at |64 so as to permit lateral movement of the spindle after the same is lowered from the position shown in Fig. 17. A lower guide consisting of a block |65 is supported in position by a strap |66 secured to the frame by rivets |61 which permits the block |65 to move towards and from the frame |6| and which is forced outwardly by a spring |68 located in a recess |69 in the frame. Thus as the needle bar |53 descends in a vertical path it enters the travelling web and is moved by the travelling web vforwardly so that the block |65 will compress the spring |68 and after the spindle withdraws the needle from the work this spring will force the block |68 back against the end of the strap |66 and the guide |62 will move the upper end of the needle bar so as to vertically align the same for the next downward stroke of the needle in passing through the work.

Looper is of more or less standard construction and will engage the thread at the end of the needle and cause it to form a loop which will be locked upon the next stroke of the needle as is usual in a single thread chain stitch arrangement of this character.

After a predetermined lengh of continuous sewing of the different plies of fabric has been accomplished, the work is severed by the cutter 41, which cooperates with the l'ower fixed jaw or edge for completing the shearing action at the desired point. This cutter 41 is secured to an arm |16 mounted upon shaft |11 which has a' lever |18 secured thereto and provided with a roller |19 extending laterally therefrom and setting in a recess |80 of the slide |8I, which is suitably guided between a pair of rolls |82 and is moved forwardly by a spring |83 to open or raise the cutter. This slide is provided with aslot |84 throughwhich the shaft 69 extends and is also provided with a laterally-extending pin |85 to be engaged by a cam |86 secured to a shaft 69 so that as this cam rotates it will move the slide rearwardly to swing the arm |18 and move the cutter downwardly to sever the work after which the spring |83 raises the cutter as above set forth. This action is accomplished very quickly with comparison to the feed of the web and such portion of the web as is fed during the passage of the cutter below the plane of the feed of the web accumulates by arcing upwardly in back of the cutter 41. The amount of arcing is such that when the cutter rises again and the web is free to move forwardly it quickly straightens out in its path of travel forwardly.

As the work is cut off by the cutter 41, it is picked up by the printing press and discharged from the machine. This printing press, as illustrated more particularly in Figs. 1 and 2, consists of a. mutilated cylinder or drum |90 mounted upon shaft |9|, the extent of the engaging surface of this mutilated cylinder being the length of the printing which will be imparted upon each piece of work. This cylinder feeds against a rubber roll |92 which is mounted upon shaft |93 so that as the work is printed it will have a support and will also be fed forwardly out of the machine and down the inclined discharge chute |94.

In order that the mutilated printing roll |90 may be properly inked, I have provided an ink reservoir 204 which has a roll 205 to transfer the ink from this reservoir to roll 206 thence to roll 201, roll 208, roll 209 and to roll 2 I0 which in turn contacts with the printing surface of the drum |90. The roll 208 is driven from shaft |93 by a sprocket chain 2| engaging gear 2 |3 on shaft |93 and engaging gear 2|2 on shaft 220 for roll 208,

which Vbeing in frictlonal contact with the other rolls causes their rotation.

Roll 2" is out of normal contact with the directly contacting inking roll 2N and is moved into engagement therewith by an arm 2M which is osclllated by a cam 203 so that each time the printing drum rotates the supports for the inking rolls will rock about shaft 220 to cause contact between the rolls 209 and 2i! so that the ink will be supplied to the roll 2 I il and in turn be delivered to the printing roll or Vdrum |90. Suitable adjustment may be provided for the deposit of ink onto the roll 206 by a thumb screw 2li opening the gate which controls the amount supplied. 'Ihe desired tension may be maintained on the sprocket chain by an arm 2 I6 and an idler 2 i1.

It is also desirable that a traverse motion be imparted to the inking mechanism and I mount cams 2i! and 2I9 on shaft 220 which has the gear 2i2 mounted thereon. 'I'hese cams engage the roller abutments 22| and 222 and cause a small traverse movement which is permitted by the length of the sprocket chain, for the better distribution of the ink.

Suitable counting .mechanismmay be provided to operate upon the rotation of the printing mechanism or some other part as. each shaft turns one revolution for each pad formed.

'I'he foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being dened and limited only by the terms of the appended claims.

n 1s apparent that the mechanism, as de# in partly or wholly superimposed vcondition for making hair waving pads.
