This invention relates to a machine for Vap.- plying reinforcing tapete sheets of material such as the uppers off shoes'and in some spects comprises an improvement upon the apparatus disclosed in the copending application of .l eroine P. Byron No; 216,702, filed August'l, 1927 and my copending application, Serial No. 267,714, 'filedgipril 5,' 1928. The above identified copending`r applications in general disclose mechanism-particularly adapted to apply'tape coated .with periiia.

nently plastic adhesive and to, permit such operation continuously to be elfected byy the movement'of the' tape and the sheet between d a pair ofrolls which ,are yieldablv urged Y. y x

:The present invention aii'ords 4mechanism for cutting,` the t'apeas a portion ofthesame is applied to each'sheet article, thisinechanism being` interconnected withthe control means which starts and stops Vthe'v feed or press rolls of the machine so that the cutting operation may vautomatically take placeeach time that tlieinacl'iinc is stopped. Provision Y of means of this character facilitates production since necessity for hand; cuttingl of the tape'V between successive sheet i articles j is avoided, and furthermore the waste of tape between successive vsheet, articles v'is also avoided. lnorderto permit .the cuttiii3`l` of the tape in thermostdesirabl'evmanner special means are afforded to operate. the cutter substaiitiallyinstantaneouslyk so that the cutting operation'inay take place while the tape is still moving; thus a. small end portion of the severed tapeV section*A mayifcontinue in movement and ,mayrpass between the rolls and applied .to the sheetinateri'al just as the machine is being` stopped. lny otlie'riwords,

the inertia of the feedrollskand parts. connected thereto permitstheir continued moi/'jefinent after the control'nieclianismqlias been operated sufficiently toeifectr tlfiecuttingi of the/tane at a point slightly before the bite; of the ro'J 4sothat tliissmall length oftapeina-y continue alcn'ig its' patliand be pressed into 'eu @agement with the edge of the sheet article b .i that is ieaving the rolls. Meaiisare `assoibboii into position hetiimfenV the rolls',

iated with the cutting mechanism to guide `and to hold the severed endy thereof in suoli amaiiner that it may bereadily advanced into frictional engagement with the iuXta-v posed portionsv of the rolls so that successive Asheet articles may have .tape applied thereto @and the tapemay be severed between the same vithout substantial loss of time. In other oFFicE wordssuccessive articles may be acted upon e by the machine substantially as'fast as they may be vff-idto the` same and the control mech anisiii be operatediiisynchronisinwith the feeding operation. y

i A further aspect ofthe invention relates to the arrangement of the tape roll and reated parts in suoli a manner that overfeedacter which isv preferably used'with the present machine is provided in rolls wherein concentricaturnsare adhesively secured to each other by a permanently plastic agglutinant.

As a result some of the agglutinant tends to stick tothe back or uiicoated surface of the tape.. While the amount of adhesive thusv occurringl upon the back of the-tape maybe negligible in so far as ak small section of the in order tov effect amore firm application of `the tape to the shoeupper. For example,

when thetape is quite yieldable and elastic vliave' found itvadvantageous to run the what greater peripheral speed than the upper roll; l/Vlien the lower roll becomes quite lstichwsucli a difference in s eeds tends to result in' the over-feeding of the tape.` Acpermit the'uiiiformcontiiiuous feedingof'the tape under a' wide variety of conditions. For this purpose l provide yieldable Vmeans ar- Vrangedtof take upv the slack in the tape and to-regulate the portion of the-same which is linel i the iresentinvention affords means to-,compensate for this edect and to Vlower"rollthat-engages the tape at a `soiiiein effective engagement with the feed roll,

thus kautomatically ensuring a constant sup-v ply of tape :to the bite of the rolls. Such means also is adapted to cooperate with the bitey of the rolls in holding the'tape suiiicient'-v ly taut readily to be acted upon by the cutter.

A machine which exemplifies the inven-y tion is illustrated in the accompanying drawingsfin which: f r' f i ffFig. lis a front elevational view of ther improved tapeapplying machine; Y

A machine of the type exemplified in the accompanying drawings preferably comprises a frame designated in general by the numeral l which may be mounted upon any suitable table or supportv 2. One end of the frame preferably supports a train of gears that are driven by aI belt plate 3 passing over a pulley 4 that is provided with a weightedV rim and which not only comprises a flywheelY but also'forms a hand wheel to permit accurate manual movement of the parts when necessary. Mounted above frame l is a transvaswell'as' any` suitable spring, not shown,Y .v may serve to press roll ldownwardly to-k ward the lower tape applying roll 20, which lis mounted upon theshaft 11 that extends through the frame l and is driven by the:v gear train atits opposite end. A depending,

boxelike projection 15 of support 12 may interfit with the upstanding projection 16 1 upon frame l to serve as a guide `Vfor the sup#l '.port.` lIt is to beunderstood that the loosef meshing ofthe gearsin the Igear train permits the support l2 to have a limited swing- ,ingmovement in relation to the frame l so llo that the rolls l0 and 2O may be slightly sep-V aratedto allow the interposition of the ,sheet material .and tape therebetween, as fully de- Y :scribed and explained in the'above-identified 'applications' n .Y j,

PA bracket extendsoutwardly from frame l'. and supports. a suitable axle 3l jupon which a tape roll 32 may be located.Y

'Preferably Ythis roll maybe formed of tape engagementv with stop 661 that is coated with a permanently .plastic adhesive which may be pressed into firm i engagementV with ay sheet at ordinary rooml temperature. vRoll 32v preferably is suryroundedby, a-suitable guard 35, a portion of which may 'be removable to permit replacement of the tape roll. Another portion of this guard is' fixed to bracket 30 and preferably"` carries a roller 36vv about which the tape run may be trained,; and which is Vpreferably located in substantially the same horizontal plane as the axis of the lower feed'roll' 2OV (Fig.r2), and the tape run ex tends therefroml about the lower portion of,

that roll so that it has a firm frictional engagement with a'considerable peripheral :portion of the same..V

. Y Mounted on a bracketv40 secured to the end of frame lisa pivot element 4l about which an arm 42 is adapted to swing. This arm carries a vpin or roller 44 that has its axis parallel to vthe axis of roll 20. One end of a spring 46 is secured vto anintermediate portion ofthe Aarm 42 and has itsopposite vend connected. to al threaded'pin 48 that is adjustably secured to the lower end of bracket by a hand nut 49 (Fig. 2), so that adjustment of the hand nut yvaries the tension of the spring 46. The tape run ex! `tends from the lower portion .of roll 20 to the element 44 as' shown andjfrom the latter is betweenV the rollv20 and the endof frame l ./(Figs. 4 and 5);

The end of this arm adjoining'the front of the machine is connected to the upper extremity of a Vcontrol rod 6l, the lower end of whichis connected Vto the rear of a control pedal 62. The rear end ofarm 'carries a dog 65 pivotally mounted thereon. A spring 67 secured to the arm-60 engages a pin 67 L upon the lower end `of the dog yieldably to holdthe-same in A fixed bracket 70 is mounted between arm 60and the roll 20 and carries voutstanding lugs'71 which have aligned openings through which knife holder'72 may. slide, the 'latter beingV held in a normally retracted position by a spring 77. The endrofthe knife carrier is providedY rwith a strikerelement 73 which may con-J veniently comprise 4the head of a screw held inV adj usted` relation to the carrier` by the nut 74.l Striker'73 is so lpositioned inV relation f to the upperend ofdog 65 that itis engaged Yby the same when the dog moves upwardly in response to the downward movement of Vthe control rod'f61, Fig. Vshowing the parts l'il just as'the cutter is being actuated. Figs. 3 and 6 illustrate the preferred form of knife 75y and carrier arrangement, the former being provided with atoothed or serrated edge 76 and having` 4one projection 64yengaged in the slotted, end of the carrier'72. as well as another projection juxtaposed to the rimvv oi? roll 2O to act as a guide. A stop l5() on the carrier determines the retracted positionv ot the knife and Vprevents. its engagement with the` periphery 'of roll 20. The` bracket is provided with lugs 7 8 that support the projecting edge oi the knife, the lower lug 78 normally being positioned to prevent accidental engagement ot the tapes-nd cuttingedge of the knife'. when the latter is in itsretracted position.'A The outer end of 'arm 60 carries a transverse pin or tape engaging element 80 that adaptedto receive the tape run as it leaves the pin lli and to hold the same out of engagement with the front portion of the n roll 20. A pin 82 is mounted upon the arm G0 adj oining` pin l80. ,A catch 84: is pivotallyY 1 mounted upon pin KV82 having its toothed edge pressed yieldably toward pin 8O by a spring 85 that engages an outstanding portion of the arm 60 -so that the Atape is nor'- mally gripped between its serratedV edge and the pin 80, the edge being suitably bei'vfeledy to permit the movement of the tape toward the bite of the rolls while catching in the* surface ot the same vto prevent its backward movement. .A sheet metal guide element also is preferably -pvotally mounted upon the pin 82 and is curved upwardly so that its inner end is juxtaposed. to the bite'olE the rolls when the arm 60 is in itsnormal operative position. rlhis inner end of the inember 90 has a transverse slot 9iV oi suitable dimensions to receive and guidet-he tape as it passes to the rolls and is pressed thereby n .into .adhesive engagement with a. sheet article A. Preferably a suitable tongue 92 may be stuck out of. memberV 90 and may serve to hold the tape up in a positionclose tothe same, thus retaining the severedV end ojl' the tape in place andy cooperating` with the catch Sain preventing the backward movement ofthe same as wellas preventing the formationoiI a slack portioniof the tape below the guide 90.`v v

A spring` 104; normally'holdsthenut 105 upon the upper end orod in engagement with the outstanding portion oit-member Gti. Thus, the end ofthe rod isyieldably held in engagement with the swinginglarnnwhile its lower end i connectedto the or hee portion of the pedal @32,l the intermediate part "f of whichvis pivotally mounted upon suitable support 110. A link is pivot-ally connected.` to the front or toe portion of pedal 62,1and its upperend isconnected to the swinging crank member i12.'v This member has, a depending arm lll that is roll.V 'lt is Vvevident that a machine oi:-

adapted to press the clutch elements 116 and 117 into engagement with each other in order to impart motion' to belt 3 and the machine.' Another yextension of crankjll is adapted to engage a ygroove in the pulley 116 in order to comprisea brake, thus mem` ber ll2 maybe swung from a position whereV in it `holds thefclutch elements in engagement witliea'ch other to permit the machine to be driven through belt 3 when the pulley il? is rotated to aposition wherein the clutchis released and a brake is applied to the pulley .116( The position ofthe control member 112 dependsupon the position of pedal 62, the iront portion of which when pressed down- `.vardly,y will cause trie engagement of the clutch and operation ofthe machine', while the movement of tne pedal in the opposite direction,.i. e., lto a position wherein the heel portion thereof is depressed, will cause the link 6iv to-move the arm 60 downwardly as in vdi'czuted in Fig.' 5. thus swinging the dog 65 `up te a position whereit engages striker element 73,l projecting the kniifel' to a cutting position and seve ing the ribbon; continued downward ,movement of arm 60 causing the dog to pass by the corner lof striker 73 and Vpermitting the knife and knife carrier again to be retracted under the influence oit springin' other words, the knifejis tripped almost instantaneously as the link 6l appreaches theend of its downward movement. it the instant of cutting7 the tape is gripped between the juxtaposed rolls, and the guide 90 and. member '841- cooperate with the rolls in holding` the tape m such a position thatv it i is readily isevered by the knife edge. Due to member 4:2 is ell'ective in maintaining substantially uniform feeding conditions so that the length of'ribbon that engaged with the peripheral portion of roll 2O may be automatically 'regulated to insure constant feeding oftlie'ribbon at the desired speed. Thus, evenv although rollv20 may be driven at a somewhat'. greater peripheral Vspeed than roll l0 in order to assure'satisfactory-laying of a more orless elastic tape, any tendency of the ,roll Ato"over-feed the tape is automatically avori ded, Vveven*l after: considerable agglutinant maybe depositedupon the srirface 'of this: +L' Y j milf; character may be utilized to apply adhesive tape such nforcing tape, to sheetartiwe y latter to' pass out frombetween the rolls.

The starting of the machine willcause the member 90, with the projecting severed end of the tape run, tobe lifted into a position where it may be'engaged'bythe rolls when the initial edge of the succeeding Vsheet arti 'cle is fed therebetween. `The spring 104 perinits the ribbon to be yieldably urged toward a position wherein it may pass between the rolls; thusundue strain upon the ribbon is avoided. A collar 125 is adjustably clamped to rod 61 ,and supports the lower end'of spring 104 so that the compression of the latter may be varied, if desired.

During these successive operations of starting and stopping the machine, as well as all other times, the member 42 is effective in permitting` uniform feeding of the tape and in avoiding' the occurrence of unnecessary slack in the same or foldingthereof adjoining roll 20. Itis thus evident that a machine of this character permits the exceedingly rapid yand convenient application of the separate sections of adhesiveitape to separate sheet articles.' i

. f Figs 7 and 8 illustrate an optional form of ribbon guide 190, wliichmay be substituted Yfor the guide 90 described above, being pario ticularly suitable foruse when heel seams are to be reinforced by adhesive tape.V Guide 190 has an intermediate rportion provided with a central groove 193 designed to engage the seam and to guide the same Vaccurately between the feed rolls. This type of ribbon guide inav be provided4 with a tongue 192 welded or otherwise secured thereto,and functioning similarly to the tongue 92 describedY above. Itis thus evident that a machine of this character may not only b'e generally-used for the application of adbesively lcoated reinforcing tape to sheet material, but alsoinay be arranged for specialized purposes, such as the reinforcing of heel'seams.
