35 Claims. (Cl. 12-17) rThis invention relates to edge-binding machines and is particularconcerned withV machines adapted to apply a binding which is secured to the work by adhesivey the illustrated machine being utilized for the application of a decorative binding to the edge and adjacent margins of the insoles of shoes.

In certain types of shoes, notably those of the sandal variety, it is customary to apply ra decorative binding to `conceal the edge of the insole, as inthe open shank or between straps and at the open toe. Such decorative bindings-have commonly been applied by sewing machines which stitch through the insole and the binding and can only be wrapped around the edge with moderate tension. It is important, however, that the binding shall cling closely to the edge of the work, as this gives the contour which it is in-` tended that the shoe shall have and because, if the binding is not applied tightly, wrinkles are almost inherent and the appearance is inferior. By the use of an adhesive for the attachment of the binding, it is possible to cause the binding to t very tightly around the edge of the insole and to hold it in that position. The advantage over sewed bindings in this respect is most noticeable in the inwardly curved shank portions of the insole and, with sandal type shoes, the appearance of this area is particularly apparent.

In the application of an adhesive binding, the folding of the binding around the edge and adjacent margins of thework requires contact of the binding progressively across the margin so that wrinkles will not `be formed and so that the binding will be drawn tightly around the edge. The adhesive for holding the binding on the work may be applied to the binding previously and allowed to dry,` or it `may be applied freshly just before the binding is directed to the applying machine, or the adhesive may be supplied on a carrier strip. In the latter case, the carrier strip is coated on both faces so that it will adhere both to the binding and to the Work and is brought into registration withthe binding just as the latter is directed through the applying mechanism.

The general object of the invention is tol pro.- vide an improved edge-binding machine capable of producing a high quality of work and,.at the same time, doing it rapidly enoughA so that the output of the machine compares very favorably with previously known methods of binding insoles. Novel features of the invention are to be recognized in improved guiding and folding de- .vices to which the operator is `enabled to present to the applying mechanism.

an insole in a simple manner, without requiring theexercise of a-high degree of skill. The assurance of a tight application of the binding follows from a novel folding construction embodying an abutment having a curved periphery and other members to co-operate with `the marginal portions of the binding regardlessV of variations in the thickness of the work.

The control of the .width of the margin of the applied binding while maintaining the moving 10 work in close relation to the folder abutment is accomplished in accordance with-other features of the invention, by theprovision of a novel construction of work-supporting and gripping members, .one of which is exed with relation to the 15 guideway and folder and the other of which is yeldably mounted, both of said members being v constructed to urge the work inwardly toward the abutment.

The rapid presentation of pieces of work to the machine is greatly facilitated, in accordance with other features of the invention, by a novel arrangement for feeding said work while pressing the binding into contact with the faces of the insole and in an improved device for cutting off the binding which, as illustrated, may be operated whilethe work is being fed. This novel cuttingoilp device is associated with a detent-carrying slide operable to grasp the cut end of the binding and bring it forward, ready for application to the nextA piece oi work, such a construction rendering it very easy for the operator to nish the binding of one piece of work and immediately present the next piece of work to the machine.

Other features of the invention relate to an improved mechanism for supplying a composite These and other features of the invention will now be described in the following speciiication, reference being had to the accompanying drawings, in which p i Fig. 1 is a front elevation of the machine Awith parts broken away and in section;

The machine is of the bench type `and comprises a hollow base 20 having an overhanging arm 22, the left end of which is closed by a removable plate 24. VA hollow cover 26, also having a laterally extending arm 28 closed by an end cover Sil, is tiltably mounted on the base 2i) v by pivots 21.

` In order to support the binding-applying mechanism, `the machine is provided with a substantially vertical frame plate 32 which is held in a recess 33 (Fig. 9) on the arm 22 by screws 34 (Fig. 1). Extending horizontally along the front face of this frame plate 32 is a groove 3S (Fig. 9) which receives a slide 38 along the face of which there is provided a guideway for a binding strip dil. The slide is retained in the groove by an overhanging upper flange 31 and an upstanding bottom flange 39` and is normally stationary, it being moved only, as will be later described, first backward land then ahead when the strip is to be severed and the end of the unused portion pushed ahead (to the left as shown in Fig. 1) into workreceiving relation to the applying mechanism. Duringthe operation of the machine in applying the binding to the edge yof a piece of work, such as an insole, the binding is held against retrograde movementl by a detent t2 pivotally mounted pn a stud 44 fastened to ltheslide. This stud, instead of being at right langles to the face of the slide, is positioned so that it extends inwardly and ahead, with respect to the movement of the binding, at an acute angle to the face of the slide. The lower operative portion of the detent is bent so that in its work-engaging position, it lies substantially parallel to the face of the sli-de and on its inner face is provided with spurs 46 (Fig. 9) lwhich grip the binding against the face of the slide. This bent end of the pivotally mounted detent 42 `moves upwardly and outwardly from the slide during forward movement of the binding strip 4D so as to provide an easily controllable amount of friction against the binding strip. At the same time, being urged downwardly by a spring 48, the detent grips the binding quickly upon attempted retrograde movement thereof.

The tension of this spring 48 may be adjusted by a nut 5l) held in place by a lock nut 52. The width of the guideway provided in the front face of the slide 38 is varied for different widths of binding by a block 54 having a horizontal sur@ face 56 to contact with the upper edge of the binding and a vertical surface 58 to hold the binding in -against the slide. The block 54 is vertically adjustable on the slide and is held in adjusted position by a screw 60 passing through a vertical slot in the block. The slide is also provided at the bottom with a thin plate B2 which has a horizontal ange abutting the bottom ange 39 of the groove 36, the upper surface 64 of said flange determining the lower limit of the binding guideway on the slide. At the left, this plate has a laterally extending finger 66 which serves, as will be later` explained, to guide an incoming end of the binding strip as it is pushed ahead to the applying mechanism.

The binding-.applying mechanism comprises a folder 10 (Fig. 9) formed -at the left end of the frame plate 32 by `a U-shaped notch defined by an upper finger 12, a lower finger 14 and an abutment 16 which, in order to reduce friction, may be in the form of a roll. This roll, against which the mid-portion of the binding is pressed as the edge of the work is pushed into the notch of the folder '10 is freely rotatable on a removable pin 11 and the roll may be of resilient material but preferably is constructed of metal in order to make it more durable. It has a grooved periphery diverging outwardly to form a rib at its lower end thereby better to coact with those portions of the insole, such as the shank portion, in which the edge is not normal to the face of the sole. The pressure of the work against the binding strip as supported by this abutment, causes the mid-portion, but frequently not the exact middle of the strip, to adhere to the edge of the work. At the same time, the upper and lower margins of the strip are folded around the marginsof the work by the action of the folder as the strip passes through the U-shaped groove provided .by the upper and lower fingers 12, 14. A guard plate 18 keeps the strip out of contact with the abutment roller 13 until it is pressed against the left face thereof by the work and this guard plate 13 has a laterally extending portion 8() which lies at the top of the roll and is beveled so as to form substantially a continuation of the curvature of the roll, i. e., laterally and upwardly. It will be noted that the vertical front faces of the ngers 12 and 14 are inclined to the left and forwardly, considering the direction of movement of the Work, away from the operator. As a result, the application of the binding to the margins of the insole is progressive across said margins, the binding touching the outer portions .of the insole margins before it touches the inner portions. This is valuable in the prevention of wrinkles. If the work is of a thickness such that it practically iills the U shaped notch, the lower edge of the upper finger 12 Iand the upper edge of the lower finger 14 will both be effective in this vway. If it is of less thickness than the groove, the action of the lower finger 14 will remain the Vsame `and the bending of the upper margin around the upper face of the work will be carried out by members to be later described. It should also be noted that bulges 82 and 84 are provided in the folder in order thereby to provide a backing for a natural fullness of the binding strip as it pa'sses from a condition where it is substantially fiat to one where it is bent toward if',

the upper and lower margins of the interposed work.

The positioning of the work with respect to this folder 'It' is effected by upper and lower work-supporting and gripping members 86 and 88, (Fig. 10) the outer corners of which are beveled at 9|? to facilitate the feeding of work such as molded insoles or those thickened at one end by shank reinforcements. The lower member 88 is fastened on. the frame plate 32 by dowel pins and a screw 92 so that its upper worksupporting face is substantially at the level of the upper face of the lower finger 'I4 of the folder.

rIhis relation and the fixed relation thereto of the surface 64 at the bottom of the guideway produces a uniform margin of binding on the bottom of the insole and if there are variations in the thicknesses of the different portions of the insole the margin on the upper surface thereof is allowed to vary because it will be covered by a slipsole as the shoe is assembled. This making of a uniform margin of binding upon the-lower surface of an insole is especially desirable in shoes in which the outsole is to be attached by means of cement because there are some binding materials to which the sole-attachingcement does not adhere. Accordingly, the uniform margin is made just wide enough so that the binding will be held, while at the same time Va large portion of the area to which a soleattaching cement isnormally applied is left uncovered. by the binding. The far side of this work-supporting member 83 is separated from the face of the lower finger 'I4 to provide a groove 94 (Fig. 9) into which the lower margin of the binding strip passes just before it is folded up against the lower face of the work, by its entrance into the U-shaped notch of the folder 10. Thegripper members are also made effective to urge the work laterally to press the binding against the abutment roll 'I6 by providing each of them with a sharp rib and these ribs 95 and S'I (Figs. 4 and 10), located one above the other near the left-end faces of the gripper members 86 and 18, are positioned at a slight angle to the path of feeding movement (see the arrow in Fig. ll) so that their tendency is to urge the work inwardly toward the abutment roll. These ribs extend forwardly and inwardly toward the path of feedingmovement. One position of an insole S is shown in dot and dash lines in Fig. 1l and the direction of feed is substantially normal to the length of the arm 22, as indicated by the arrow.

The upper gripping member 86 is mounted at the end of the lower arm of a bell-crank lever 35, received in a groove 98 along the upper face of the frame plate 32, and pivotally mounted therein on a stud |60. It is desired to be able to lift this upper work support and gripper B -for the introduction of a piece of work. To this end, the bell crank 96 has a laterally extending pin |02 over which there engages the hookshaped 'end |64 (Fig. 6) of a rod |06 slidable in the end plate 30 (Fig. 1) and traversing a passageway |68 formed in the arm 23 of the cover ycrank |22 pivotally mounted in the cover 26 and engageable at its laterally bent upper end by two nuts `|22 on the rod |06. The action of the treadle rod is effected against the resistance of a spring-pressed pin |24 and clockwise movement of the bell crank H6, as viewed in Fig. 1, is limited by a Stop pin |26. The limit of downward movement of the arm of the bell crank 96 which carries the work gripper 86 is determined by an adjustable stop screw |23 (Fig. 6) contacting the frame plate 32. Carried also on this bell crank 96 is a deflector plate |39 having a curved lower end |32 adapted to rest against the partially infolded upper margin of the binding (Fig. thereby to insure the deflection of this upper margin toward the Work in ,the case of unusually thin pieces of work, where the work is enough thinner than the space between the folder fingers so that the upper finger 'I2 is not fully effective in tilting this margin toward the work.

As the binding is thus applied to the work, a feeding movement is imparted to the bound insole by a mechanism similar to that utilized in folding machines and particularly to a mechanism such as is shown in Letters Patent of the United States No. 1302,598, granted February 19, 1929, on the application of P. R. Glass. There, as herein, the feeding of the work is accomplished by coacting members which grip the margin of the work and carry it forward. These members are termed a hammer |40 (Fig. '7) and an anvil |42, the latter being detachably mounted on an anvil arm |44 which is clamped to the outer end of a hollow shaft |46 journaled (Fig. l) in the arm 22 of the frame. A hammer arm |48 is pivoted to the anvil arm at |50 and its lower end is connected to a rod |52 passing through the hollow shaft |46 and adapted to be oscillated axially to move the hammer toward and away from the anvil. Movement of the hammer in gripping the work is effective to complete the application of the upper margin of the t binding and ismademore so by reason of the fact that the hammer is provided with a tiltable face-plate |54 (Figs. 'l and 8) which has an upstanding semi-circular flange IE6 slidable in a correspondingly shaped groove in the under side of the hammer head. The parts are kept in this relation by the transverse pin |58 which passes through a curved slot |60 in this upstanding flange |56. The hammer face-plate |54 presses the binding smoothly against the stock becausejt is biased to always contact with the marginal portion of the binding iirst at the corner of the insole S (Fig. 7) and then to bring the binding progressively into contact with the upper surface of the insole inwardly of the margin thereof (Fig. 8). To this end, the hammer is provided with a wire spring |62, the outer end of which enters a recess in the face-plate |54 and the other end of which enters a passage |64 in the hammer arm |48. The upper side of the hammer head is provided with a groove IE6 to receive this wire spring and keep it from twisting. The shape of the work-engaging face of the anvil is well sho-wn in Figs. 6 and 9 and from these it will be seen that the anvil is provided with an inwardly andrearwardly directed edge |10. It is desirable that the vertical face at this edge I'ID be brought as close as possible to the folder 'It and to this end, the lower arm I4 is cut back, as shown at |'I2 in Fig. 6.

The face-plate |54 of the hammer has a shape complemental to the shape of the work-engaging face of the anvil. As a result,` the upper finger 'I2 of the folder is cut back to permit the hammer to be brought into close relation thereto. The hammer is made somewhat wider than the anvil so that when the work is very thin the hammer will still overlie the whole of the margin of the work and will not be carried outwardly by reason of the pivotal mounting of the hammer arm |48 to a point to the right, as seen in Fig. 8, such that the left edge of the hammer plate |54 might not cover the work. By reason of this construction the rear edge of the anvil and the corresponding edge of the hammer extend diagonally of the margin of the work inwardly and forwardly of the work so that the bite of these members corresponds as nearly as possible to the natural fold of the binding as it is brought gradually into contact with the upper face of the work, thus avoiding any tendency to plait the binding around sharply curved portions, such as at the toe end of the sole S. It will be understood that the bias cut of the binding permits it to stretch to the amount which may be needed so that the binding can be applied smoothly around either convex or concave curves of the work.

In many insoles, the edges at the shank portion are not normal to the face of the sole, but are undercut, when, as usual, they are presented right side up and additional assistance in pressing the binding firmly against such undercut edge portions is given by a spring-wire folder |14 having an inclined portion |16 terminating in a vertical end |10. This folder wire |'l4 is coiled at |80 to cause the Vertical end |18 to rub` on the vertical face at the back side of the lower nger 'I4 of the folder. As a consequence, when the anvil arm |44 oscillates toward and away from the lower finger 'I4 of the folder, the inclined portion |16 of the folder wire is given an oscillation transversely of the margin of the work and wipes the binding into rm Contact with such undercut edge portions.

Oscillation of the hammer arm |43 to bring the hammer against the work, by oscillation of the rod |52 axially of itself, is effected by a cam |82 (Fig. 1) on a driven shaft |84 journaled in the base 20 of the machine. This cam imparts a vibratory movement to a forked lever |86, which movement is transmitted through a link |88 and two arms |93, |92 to the rod |52. The arms |90, |92 are journaled on a common pivot rod |94 and are held yieldably in the relation shown by a spring-pressed plunger |96 within a casing |98 carried by the arm |90 and by a stop screw |99 carried by the other arm |92. By this arrangement, the blow of the hammer is softened. At the same time, in order to compensate for variations in the thickness of the stock, a lighter spring 200 surrounds the rod |52 between the arm |92 and a nut on the end of the rod.

Oscillation of the anvil arm |44 to feed the work after the hammer and anvil have been brought into gripping relation with the work is effected by another cam 202 ron the driven shaft |84 and by this latter cam movement is imparted to a forked lever 204, the lower end of which is pivoted to an arm on a rockshaft 206. Similarly secured to another arm on the rockshaft is a link 208, the upper end of which is connected to an arm 2|0 clamped on the hollow shaft |46. By this arrangement, the oscillations imparted by the cam 202 are transmitted to the hollow shaft |46 on which the anvil arm is clamped an-d the extent of these oscillations is controlled, as in the patented machine, by a ngerl piece 2|2 extending outwardly through a slot inthe casing. The

position of this finger piece is determined by a pin 2|4, which may be positioned in any one of a series of holes (not shown). On the cam shaft |84 is a driven pulley 220 which may be connected to the shaft at the will of the operator by a clutch mechanism 222 having a trip member 224 pulled to starting position by a treadle rod 226, as more fully shown and described in Letters Patent of the United States No. 2,044,501, granted June 16, 1936, upon the application of P. R. Glass.

After the binding has been applied to nearly all of such portions of the periphery of the Work as is desired, the binding may be severed by a knife 230 carried at the outer end of an arm 232.

This knife has a diagonal cutting end inclined on a long bevel to minimize any crushing or wrinkling of the binding as the knife becomes dull. The arm 232 is clamped to one end of the transverse stud |00 while integral with the other end of this stud is a depending arm 234 (Fig, 6). The lower end of this arm 234 is slotted to receive a pin 236 passing through a slot 238 in the frame plate 32 and attached to the slide 38. As a consequence, the slide and the knife move simultaneously, the slide 38 (Fig. 9) moving to the right as the knife 230 descends to sever the binding. As the slide moves to the right, it forms a recess 240 (Fig. 4) transversely of the guideway to receive the knife blade. This recess has an extension 242. The recess 240 is formed between a curved edge 244 formed in the frame plate 32 and a complementally curved edge 246 on the slide. The blade-carrier arm has a depending portion 248 against which the blade is clamped by a reinforcing plate 250 (Fig. 9) held on the end of the arm 232 by a screw 252. The far side of the depending portion 248 and the point of the blade 230 pass very close to a ledge 254 at the back of the recess 240 and thus pass behind the binding strip, which is held against crumpling or outward deection toward the operator by a finger 256 attached to the bell crank 96 carrying the upper gripper 86 and is also held by the overhanging surface 58 (Fig. 9)

at the inner side of the block 54. An inclined vif() one side of the knife it is attached to the work still being gripped by the members 86, 88 and at the other side is smoothed out frictionally by the rubbing action of the detent 42, which moves along the surface of the binding as the cut is being made. severed and a piece of work completed, which is removed from the machine, reverse movement is imparted to the slide 38 as the knife is returned to its upward position, shown in Figs. 1, 6 and 9, and during this return movement of the slide, the studs 46 on the Idetent grip the binding against the slide and cause the cut end to be moved ahead to the left into position where it can be pressed against the abutment '|6 by the next piece of work presented to the machine. During this movement, the upper edge of the binding is held against the slide by the surface 58 of theV block 54 and the end is pushed into the groove 94 between the folder and the work-supporting member 88 (Fig. 11) by the laterally extending finger 66 carriedvon the slide.

If, at the beginning of the work or when a new piece of binding is to be threaded through the machine, it is desired to lift the detent 42 When, now, the binding has been so that it will be out of the way, the slide 33 .maybe moved' still farther to the right thanthe position shown in lig.` 4 until the detent'contacts with a cam finger 262 (Figs. 1 and 2) which is on a block 262, attached to theV right end of the frame plate 32 by a screw 264. The knife 230 will then enter the recess extension 242. In order that the slide may not always move far enough to the right to lift the detent, a stop 286 (Fig. 2) is provided which extends downwardly into the groove 36' provided for the slide. When the operator wants to make this cam finger 265i) effective, he has only to lift the stop 2F66 by turning the laterally extending upper end 228 thereof to contact with a curved surface 2li) (Fig. 9) formed on the upper edge of the frame plate 32, thereby camming this stop pin 25S upwardly against the tension of a spring plate 272' held in position by the same screw 264 and having its other end 259 (Fig. ll) forked to engage in a grove around said pin.

.actuation of the slide and knifein the abovedescribed manner may be effected by the operator at any desired time, even while the machine vis feeding the work, by pulling down on a treadle rod Z'llv (Fig. 1) to swing a bell-crank lever 2151; 218y pivcted on transverse studs 28D in the base of the machine. The treadle rod is attached to the short end 216 which extends to the right fromy the far end of a yoke portion '219 (Fig. 3)" supporting the upstanding end 218. This end 218 carries a pin 282 received in a grooved blockZlll-fastened: on a rod 28:` which is slidable in the arm 23 of the cover. This rod 236 is urged to the left (Fig. 1) by a spring 282 received in av recess of the cover arm 28 and acting on a block 290 on saidy rod within the recess of the arm. A depending pin 2.9!, received in a slot in the lower side of the arm 23, prevents rotation of the rod 285. The arm 21B of the treadle-operated lever is also urged counterclockwise by a spring 292 to contact with a stop pin 224 so` that it will always be in position for engagement in the notch of the'block 284 when the cover is lifted and returned to position. The outer end of the rod 286, threaded in the block 222, is bent downwardly and then horizontally and is notched; as shown at 296' (Fig. 6), to receive the pin 23S on the slide. 'Ihis notched end 29S along withthe notched end |04 of the rod 526 permitsV the cover to be lifted around its pivots 2l when it is desired to obtain access to the inside of the machine for lubrication or adiustment. It should be noted, furthermore, that endwise movement of the rod 282 to the right is limited by a. stop block( 293` threaded in the cover and heldin adjusted position by a lock nut. The rod 235 will not ordinarilycontact with the stop 258 `because of the limitation of the slide movement by the stop pin .265i (Fig. 2). If, however, this stop pin. has been lifted, the right of the rod 226 `can only move as far as permitted by the stopblock 298; thus permitting the operator to depress the treadleY (not shown) attached to the rod Z'Hlfirmly without feario damage-to the slide 38 orthe knife- 23E?.

The binding, which is to be attached to the work by adhesive, may be freshly coated with a rubber or a thermoplastic adhesive or it may be coated with a thermoplastic adhesive which is activated, as by heat, just as the bindingis introduced into the applying machine. Still another arrangement has been proposed inwhich the adhesive for the attachment of thebindingis furnishedby a separate carrier strip 300 (Fig. 12),-

which strip is coated on both its faces so that it adheres to the binding itself and to the work and thus serves for the attachment of the binding to the work, One of the numerous reasons why an arrangement of this sort is advantageous lies in the fact that many different kinds, colors and widths of binding material are employed in shoemaking. If these are purchased with adhesive coatings, there is a possibility of deterioration of the coatings thereon before the binding is all. used. On the other hand, if the bindings vstrips are uncoated, the manufacturer is require-d only to provide himself with a sufcient quantity of the adhesive carrier strip 32S to take care of the current production of shoe parts and does not have to maintainv a quantity of coated binding which may or may not be completely usedI during a particular seasons run.

The coating employed on this carrier strip 3D0 is commonly of the pressure-sensitive type, an example of which is found in the so-called surgeons tape which is in widespreadv household use. With a carrier strip of this kind, it is essential that a separator strip 302 shall also be employed, which is interleaved between the coils (on a roll 33D) 'of the carrier strip to prevent them from sticking together. Such a separator strip is frequently made of crinoline, similar to coarse cheesecloth, which adheres only lightly to the carrier strip but must be separated therefrom and disposed of before the carrier strip 302 is united with the'binding lli). The binding strip 4! and the carrier strip 329 are brought together in alinement with each other before they enter the guidevvay` 56, 54 on the slide 38. This alining of the two strips is accomplished by 'bringing them together within the flanges of a guide roll tile freely rotatable about a stud 322' (Fig. 1) which is fastened to an arm 308 bolted at 322 (Figs. 6 and 11) to the anvil arm IM of the feed mechanism. The purpose of this mounting will be later described. The arm 323 may be adjusted to bring the roll 324 into alinement vertically with the-guideway` 56, Bil. This guide roll 324 has a bottom flange 3i 2 while on the stud 326 thereis threaded for adjustment with respect to the flange a normally stationary, inverted, cup-shaped member 3M which with the flange provides an adjustable guide channel adapted to receive bindings of varied widths. The peripheral surface of the cup-shaped member 3M is corrugated and the member is held in adjusted position by a friction detent in the form of a flat plate 365 having a vertical rib en tering the corrugations and attached to theend of the 328 by a screw M8. This same screw also serves to hold in position a dellector plate the binding-contacting portion of which lies obliquely inclined with respect to the plane of the approaching strip .tim at such an angle, as shown in Fig. 1, as to tilt the lower edge of the carrier strip tim upwardly (Fig. 11) as it appreaches the fla-nge 312 of the guide roll so that the strip will move into engagement with the roll 3M without 'contacting with the edge of the flange 322. ,A supply roll 322 (Fig. 12) of the binding strip di), wound` on a exible core 324, may be supported in any desired manner and is herein shown. as freely rotatable about a stud 325i as it rests on a smooth horizontal table 328.

The binding stripY itl is directed about a small stud 22d (Figs. 1 and 11) attached to the arm 323 and passes thence to the guide roll 324. By causing the binding .lieto enter the space between the nanges of the. guide roll at a point separated from the entering point of the carrier strip 366, a proper registration of the two strips is insured before they are brought into actual contact with each other. The binding is kept from slipping off this stud 364 by a guard 388 secured to the stud by a screw 386 and forming a loop through which the binding must pass, the lower end of the guard being attached to the arm.

The supply roll 336 of the combined separator strip 362 and carrier strip 360 is positioned on a freely rotatable table 332 having a hub 334 supported by ball bearings 336 on a post 338 attached to a pedestal 346. This combined roll 330 is mounted on a core 342 which is centered by a conical portion 335 (Fig. 14) of the hub and is held against the table by an eccentrically mounted locking disk 344 positioned on a stud bolt 346 by which the table 332 is attached to the hub 334.

The crinoline strip 362 is disposed of automatically by being wound about a pick-up reel 356 (Fig. 12), having a slot 352 therein into which an end of the strip 362 is inserted. The pick-up reel 353 is pivoted at the end of an arm 354i, itself swingably mounted on a bolt 362 at one end of an arm 356, the other end of which is clamped by a bolt 358 to the post 338. The arm 354 is urged in a counterclockwise direction, as viewed l in Fig. 12, by a spring 366 coiled about the bolt 362 and having its ends engaging the respective arms. This spring holds the periphery of the coils of crinoline on the pick-up reel 356 against the coils of the roll 330 regardless of the variations in diameter thereof.

The coils of crinoline on the pick-up reel 35|! are also held against the coils of the roll 330 by the pull of the carrier strip, acting to assist the spring 366, and the pressure between these rolls can be Varied by changing the angular position of the arm 356. For example, clockwise movement of this arm, as viewed in Fig. 12, will cause an increase in pressure between the rolls. It will be understood that the force which winds up the crinoline strip is applied at the point of contact between the two rolls, thus preventing any slack between the point of separation 386 between the strips and the point of contact between the rolls.

The even winding of the crinoline strip on the reel 353 and proper support therefor when of increased diameter are insured by a supporting arm 364 (Fig. 13) held by a set screw 366 on the post 338 and having a horizontal portion 368 which is at the left of the table 332. Another arm 31D overlies the two rolls and forces the crinoline strip to wind properly. This arm is pivotally mounted on a pin 312 traversing the upper end 314 of the stud 338 thus permitting new rolls 33|) to be passed over the arm. A proper horizontal position of the arm above the rolls for any particular width of binding and hence width of carrier and-crinoline strips is assured by a stop screw 316 passing through it and resting on a iiange 318 above the hub 334.

Inasmuch as there is a tendency for the carrier strip 366 to adhere lightly to the crinoline separator strip 362 at their point of separation 336 and since it is desired that the combined binding and carrier strip be delivered to the applying machine without any undue tension which, if present, tends to draw the binding away from the work at concave edges, provision has been made for intermittently drawing small portions of these strips from the supply rolls mechanically in direct proportion to the amount of binding which is being used. It will be understood 'that the arm 363 oscillates away from and toward the operator with each feeding and retrograde movement respectively of the anvil |32. When, as viewed in Figs. 11 and 12, the arm 366 is oscillated forwardly, with respect to the direction of feed of the work, or toward the rolls, the binding strip and the carrier strip pass freely around the roll 304 and the stud 384, because at that time the strips are being drawn forward through the guideway 56, 64 by the grip of the hammer and anvil on the work. There will, therefore, be no slackness in the combined strip. On the other hand, during the retrograde movement of the anvil |42 and arm 338 when the work is stationary, owing to the position of the roll 364 with respect to the guideway 56, 64 and the supply rolls 322 and 336, the length of binding material and of the carrier strip between the guide and supply rolls is increased by substantially the extent of the feeding movement of the anvil thereby causing an additional length of combined binding and carrier strip just sufficient for the succeeding feeding movement of the machine to be drawn from the respective rolls. It will be recalled that the work is held at that time against retrograde movement by the pressure applied by the upper supporting and gripping member 86, this pressing action being derived through the rod |66, the connected bell cranks and the spring-pressed stud |24 (Fig. 1).

In the operation of the machine, assuming that supply rolls 322 and 33u have been provided and the strips have been threaded into the machine, the upper work gripper 86 having been raised by raising the treadle rod |16, a piece of work, such as an insole S held right-side up, will be pressed against the adhesive binding strip opposite the abutment roll 16 in the folder. Power will then be supplied to the cam shaft |84 by depressing the treadle rod 226, whereupon the hammer |46 will descend to grip the work against the anvil |42 and will draw the work and the binding through the machine during the first half of one cycle of its operation. During this operation, the lengths of binding and carrier strips drawn from their respective rolls during the preceding retrograde movement of the anvil are united in passingthe roll 334, and the combined binding and strip after passing under the detent 42 'and through the guideway 56, 64 will be attached at a mid portion of the strip to the edge of the insole as the latter is pressed against the binding supported by the abutment roll 16. At the same time, the binding, being drawn between the fingers 12 and 14 of the folder, will be turned over and under the margins of the work and finally will be forced into rm contact with those margins by the action of the hammer and anvil. i l 'W During the retrograde movement of the hammer and anvil, the work will be held by the cooperating grippers 66 and 88 and by reason of the action of the retrograde movement oi' the guide roll 304 in increasing the total distance between the point of attachment of the combined strip to the then stationary work and the rolls, lengths of carrier strip and of binding strip will be drawn from the respective rolls, these lengths being substantially equal to the length of `feeding movement imparted to the work by the machine. It will be recalled that the oscillating spring wire |16 is effective to vcause the binding to adhere to undercut portions, such as at the shank portion of an insole, and that the deflector plate |30, |32 (Fig. 6) is eifective to cause the binding to overlie the upper margin of the sole in the case of relatively thin worlrzlv Aswthebinding of the-insole Vis* completeddit being Y,understood-fthatl some insoles are bound along-portions of-their periph-- er-y while other insolesare bound: completely,
