Patented May 27, 1952 UNITED STATES PATENT OFFME MATERIAL Charles E. Marks, Lee, Mass, assignor to General Electric Company, a corporation of New York Application September 1, 1948, Serial No. 47,246 7 Claims. (01. 154-115) The present invention relates to a method and apparatus for attaching a plurality of strips of material, at spaced and equal intervals, to another strip of material. More particularly, my invention relates to an improvement over the method and apparatus for transversely afiixing a plurality of conducting tap straps to a wider strip of insulating mounting material disclosed in the copending applications of Raney, Serial No. 41,804, filed July 31, 1948, Serial No. 116,346, filed September 17, 1949, and the copending application of Hogue & Hamilton, Serial No. 46,206, filed August 26, 1948, now Patent No. 2,597,863, each assigned to the same assignee as the instant application. The broad aspects of any features disclosed in these copending applications and common to the instant application are to be regarded as prior art with respect to this present application which is directed to a particular and distinguishing combination of elements not disclosed in these prior art applications. The claims of the present application are specifically directed to the apparatus of the present invention while claims to the method have been presented in my copending, divisional application, Serial Number 116,316, filed September 17, 1949, and assigned to the same assignee as the present application, now Patent No. 2,597,885.

It was indicated in aforementioned application Serial N 0. 46,206 that in order to employ the combination of a plurality of conducting tap straps afiixed to a longitudinal strip ofv insulating mounting material in the manner disclosed in copending application Serial No. 18,104, filed March 31, 1948, now Patent No. 2,547,644, the longitudinal strip of insulating paper must have the conducting tap straps afiixed thereto not only at spaced and equal intervals but a portion of each tap strap must extend a predetermined distance, laterally beyond a longitudinal edge of the mounting strip, approximately equal to the distance it is desired to have the tap strap project out of the finished condenser roll. The desirability and reasons for having the projecting portion of each tap strap free of any contamination, such as adhesive material employed to adhere the strap to the mounting strip, was also pointed out.

I In addition to the fulfillment of these requirements, however, it is also desirable to carry out the operation of afiixing tap straps and completing a great number of finished rolls in a minimum of time. Reduction in the time required to assemble a finished roll obviously would be realized if the necessity of momentarily stopping the movement of the mounting strip could be eliminated while each tap strap is being affixed thereto. However, aside from the problem involved in the realization of this objective, an additional problem is presented in that it would be difiicult, practically, if not impossible, to apply adhesive material to a mounting strip while in motion.

It is, therefore, an object of my invention to provide an improved method for affixing, at spaced and equal intervals, a plurality of conducting tap straps to a mounting strip of insulating material.

It is also an object of my invention to provide a method for afl'ixing such tap straps While the mounting strip is in motion.

It is a further object of my invention to provide a method of afiixing conducting tap straps to a mounting strip whereby adhesive material is applied to only such surfaces of the tap strap or mounting strip as will be in engagement after afiixing to each other.

It is still a further object of my invention to provide a new and improved apparatus for automatically carrying out the method described.

My invention will be better understood from the following description when taken in connection with the accompanying drawings and the scope of my invention will be pointed out in the appended claims.

In the drawings, Fig. 1 is a perspective and diagrammatic representation of an apparatus embodying my invention; Fig. 1a is an enlarged edge view of an adhesive applicator element incorporated in the Fig. 1 apparatus; Fig. 2 is a perspective and diagrammatic illustration of a similar apparatus incorporating a modification of my invention and Fig. 2a is an enlarged edge view of the adhesive applicator element incorporated in the Fig. 2 apparatus.

Referring now to Fig.1 of the drawings, It represents a supply roll of insulating mounting material rotatably mounted on spindle or shaft II which in turn is supported by a stationary frame work not illustrated in the interest of simplicity. As supply roll 10 is unwound, by drive means to be described hereinafter, the longitudinal strip of mounting material 12 therefrom is directed toward the left in the direction of the arrow and during this leftward passage passes over and is temporarily supported on supportv fed from a supply roll or reel, not shown, in the direction of the arrow toward and transversely over the platform l3 and the longitudinal supply strip of mounting material I2. To feed the conducting strip l4 transversely toward the mounting strip I employ feed means comprising a pair of cooperating feed rolls I5 and I6 fixedly mounted on shafts l1 and I8 respectively which are positively interconnected by spur gears I9 and respectively. Shaft I1 is driven clockwise, as viewed, by bevel gear set 2 I, shaft 22, bevel gear set 23 and shaft 24 from a pulley or chain sprocket mounted thereon but not shown which in turn may be driven by a belt or chain from a motor neither of which are illustrated. Notches I5 and I6 have been respectively cut across the con- Q tacting periphery of rolls I5 and I6 which are so mounted on their respective shafts that during each revolution thereof notches I5 and It are bisected by a line interconnecting the centers of the rolls or are adjacently disposed on opposite sides of the conducting strip I4 therebetween. Since the periphery of the rolls are out of engagement with the strip at thistime the feed thereof is obviously terminated for a momentary period during each revolution of the feed rolls. A pair of cooperating

rotatable discs

25 and 26 between which conducting strip I4 is directed while being fed by the feed rolls toward platform I3 is positioned between feed rolls I5 and I6 and the platform.

Discs

25 and 26 are fixedly mounted on and positively driven by shafts 21 and 28 respectively through spur gears 29 and 30 by idler gear 3| which meshes with gear I9 fixed to feed roll shaft I1. These discs are 'so positioned on their respective shafts with respect to each other and strip I4 is so directed therebetween that the longitudinal axis thereof is aligned with the central plane of rotation of each disc. Although disc 25 is a complete circular disc, disc 26 comprises substantially the sector of a circle with I portion of disc 26 engages the under surface of conducting strip I4 so that for a short period each revolution of the discs, disc 26 is completely out of engagement with the conducting strip It as it is fed between the discs. It should be observed at this point that disc sector 26, as better illustrated in Fig. 1a, has a thickness less than the width of conducting strip I4 and the circular periphery portion thereof rotates in a bath of adhesive material 32 in supply reservoir 33 which is provided with any suitable heating means to maintain the adhesive material therein in a liquid state.

Between feed rolls I5 and I3 and

discs

25 and 26 at a predetermined distance from platform l3 and the adjacentlongitudinal edge of mounting strip [2 is supported a conducting strip severing means or knife substantially the same as the severing means disclosed in the above mentioned copending application of Hogue and Hamilton, Serial No. 46,206. This severing means comprises a die and strip support 34 rigidly fixed to the apparatus frame work and punch or knife housing 35 slidably mounted for vertical movement at the rear, but not shown, on the frame work. The forward lower end 35 of housing 35 is'formed or machined to aknife edge, the purpose of which will be apparent as the description proceeds. Conducting strip holding element 36 is mounted'for vertical movement'within housing 35, biased downward by a'spri n'g therein and aligned for engagement with die slot 31 which has a width and is so aligned as to slidably accommodate conducting strip I4 as it is fed toward mounting strip I2. The downward travel of holding element 36 under its spring bias is limited by the engagement of a pin 38 affixed thereto with the lower edge of a slot39 in the side wall of knife housing 35. Normally, holding element 33 is biased out of engagement with die slot 31 by springs 40 interposed between top plate 4!,

fixed to housing 35, and the slotted flange 42 of a substantially channel shaped backing member 33 fixedly mounted on the frame work. Upward thrust of springs Ml is resisted by engagement of a bolt 44, passing through plate 4| into housing 35, with the rounded end of an adjustment screw 25 threadably mounted in a beam or lever 45 rotatively pivoted on pivot pin 41 fixedly mounted on the apparatus frame work. Cam wheel 38 is rotatively mounted at one end of lever 55 and is "biased into engagement with cam 39 mounted on an extension of drive shaft 24 by spring interposed between lever 46,-at the other end thereof opposite the pivot pin 41, and flange 5i of channel shaped backing member 43. An extension 52 is provided at this end of lever it to which one arm 53 of a toggle is pivotally mounted at pivot pins 54. A toggle tamper 55 having a length approximately equal to the width of the mounting strip -I2and a rounded tamping surface is pivotally mounted transversely with respect to the mounting strip to the lower end of arm 53 by means of pivot pin 55. This combination comprising atoggle is biased in a counterclockwise direction by'spring 51, attached to arm 53 and a downwardly projerting portion of lever extension 52. However, stop 53, part of the downwardly projecting portion, normally prevents counterclockwise movement of the toggle tamper beyond the position indicated which is such'that the longitudinal center line of the tamping surface on tamper 55 is aligned with the longitudinal axis of the conducting strip I4 fed over the mounting strip l2. Moreover, arm 53 is so mounted with respect to platform I3 and mounting strip I 2 that its movement about pivot 54 is in a plane normal to the platform surface and coincident with a horizontal center line thereof and the longitudinal axis of the mounting strip.

So as to prevent back-lash of conducting strip it, a pairof friction blocks 59 are provided between which thestrip is pulled by feed rolls I5 and It. The lower friction block is supported on the stationary frame work while the upper block is movable but biased downwardly by spring 60 interposed therebetween and a part of the frame work 6!.

A friction drive roll 62 is fixedly mounted on shaft 63 which is positively connected by spur gear 64 fixed thereto and spur gear 55 to drive shaft 2%. 65 represents a partially wound reel of mounting material with tap straps affixed thereto in substantial rolling engagement withv friction roll 62 and wound on a split mandrel mounted on reel up shaft 6? which is supported on a radius arm, not shown, which in turn is pivotally mounted on the apparatus frame work, as illustrated in the above mentioned copendingapplication of Hogue and Hamilton. It is by means of friction roll 62 that the mounting strip I2 is unwound from supply roll I0 and directed over platform It by idler guide'rolls 58 and 69 around friction roll 62 and'eventually rewound into-a-reel-s-uchas 65. Them'ountingbfshaft 51 on a pivoted radius arm results in constant rolling engagement of the reel being rewound with friction drive roll 62 regardless of the amount of mounting material that has been rewound into a finished reel. 10 represents an ironer roll rotatably and also slidably mounted for vertical movement on the apparatus frame work but biased downwardly toward the upper surface of platform I3 forrolling engagement with moving mounting strip'I'z.

To operate -.the apparatus hereinbefore described, an end of mounting strip I 2 is first manually pulled over support platform I3, directed around

guide rolls

68 and 69 and friction drive roll 62 as shown and attached to the split mandrel on shaft 61 and an end of conducting strip,

I4 is manually directed between friction blocks 59 into frictional engagement with the circular peripheries of feed rolls I5 and I6. Then the drive motor, not shown, which turns drive shaft 24, gear 65 and cam 49 in a clockwise direction is started. Thereafter all the steps of my invention are executed automatically. Drive feed'roll 62 unwinds the longitudinal mounting strip I2 from supply roll I continuously across support platform I3 around the guide rolls and rewinds it intothe reel 66. Feed rolls I and I6 feed the conducting supply strip through the die slot 31 toward and transversely over continuously moving mounting strip I2 for a lineal distance equal to the circumferential dimension of the contacting periphery of a feed roll.

Simultaneously during the feed, the circular periphery portion of disc 26 which has previously rotated in the liquid adhesive material 32 engages the bottom surface of conducting strip I4 to apply a strip of adhesive thereto having a lineal dimension equal to the circumferential dimension of the engaging periphery of the disc. Because of the location of disc 26 with respect to the adjacent longitudinal edge of moving mounting strip I2, the angle subtending the circular periphery of disc 26 and the synchronization thereof With'the feed rolls, this strip of adhesive is applied only to that portion of strip I4 which is adjacent to and fed over mounting strip I2. Moreover, since disc 26 has a thickness less than the width of strip I4 and because the longitudinal axis thereof is aligned with the central plane of rotation of disc 26, the adhesive material which is applied is confined to a very narrow strip about the longitudinal center line of the bottom surface of the conducting strip.

Thereafter, notches I5 and I6 of feed rolls l5 and I6 respectively become adjacently disposed at which time the feed of strip I4 is momentarily stopped. The various elements of the apparatus are interconnected as hereinbefore described and so synchronized that during this momentary period the detented or depressed portion 1| in thecontacting surface of rotating cam 49 begins to roll into engagement with cam wheel 48 permitting biasing spring 50 to turn lever or beam 46 clockwise about its fulcrum or pivot 41 thereby depressing housing 35 downwardly, against the biasing action of springs 48, and the lower end of holding element 36 into engagement with conducting strip I4 in die slot 31.

Additional rotation of cam 49 results in further downward and slidable motion of housing 35 this time relative to holding element 39, which having engaged stationary die slot 31 and strip I4 remains stationary, whereupon the knife edge 35' of housing 35 passes through and severs conducting strip I4. As pointed out in the above indicated 'copending application, by virtue of the resulting compression of the spring within the housing, this additional downward movement of housing 35 imposes considerable holding pressure on strip I4 during the actual severing thereof. This clockwise motion of the beam 46 also and simultaneously lowers toggle tamper 55 into rolling and pressure engagement with that portion of the conducting strip which has previously been fed over the mounting strip I2 whereby the adhesive coated undersurface of the conducting strip now severed is pressed into engagement with the mounting strip. The severed conducting strip thus adhesively affixed to the continuously moving mounting strip will promptly move therewith to the left and because of the friction between the conducting tap strap and the curved lower surface of; the tamper 55 and the pivoted mounting thereof the toggle tamper elements will move a short distance therewith clockwise about pivot pins 56 and 54 against the biasing action of spring 51 after which disengagement of the detentecl portion H of rotating cam 49 will result in counterclockwise movement of beam 46 about pivot 41 to raise tamper 55 for free counterclockwise movement of arm 53 about pivot 54 under the biasing action of spring 51 into engagement with stop 58. This movement of lever 46 simultaneously permits upward vertical movement of punch or knife 36 under the biasing action of springs 46. Spring biased roller 10 serves to apply pressure'for an additional short period to the afifixed conducting tap strap as it passes therebetween and the surface of support platform I3.

Thus, a new and improved method and means has been provided whereby a conducting tap strap 12 having a predetermined portion projecting beyond or exterior a longitudinal edge of a strip of mounting material is automatically affixed thereto at spaced and equal intervals while the mounting strip is in continuous motion. Moreover, in accordance with this new method and means both surfaces of the projecting portion of each tap strap are entirely free of any insulating material such as the adhesive em ployed to bond the tap to the mounting strip. 7

In Fig. 2, I have illustrated an apparatus somewhat similar to the Fig. 1 apparatus except that a modification of my invention is embodied therein and other features have been incorporated which render this machine more flexible than the apparatus illustrated in the Fig. 1 embodiment. As in the embodiment of Fig. l, a' supply roll of insulating mounting material is rotatably mounted on a spindle or shaft 8]. A longitudinal strip of material 82 is unwound therefrom and pulled under idler rolls 83 and 84 across stationary platform 85 and rewound into a finished roll 86, after tap straps have been aflixed thereto, by friction roll 81. Friction roll 81 is fixedly mounted on shaft 88 which is con-f tinuously rotated clockwise through bevel gear set 89, shaft 90, bevel gear set 9|, drive shaft 92, and drive pulley 93 keyed thereto by a motor through a belt, neither one of which are shown;

A supply strip of conducting material 94 is fed from a supply reel 95 through a guide slot 96' toward and transversely over the mounting strip 82 and the platform 85 by a pair of cooperative. feed rolls 91 and 98. Feed rolls 91 and 98 are keyed respectively to rotatable shafts 99 and I60 which are positively interconnected by spur gears I8I and I82 respectively. driven by a bevel gear I03 keyed to feed roll shaft 99, bevel gear I04 meshing therewith and The feed rolls are,

BMRSBA shaft :II15 through .avariable speed drive ;com-

endrthereof is; hollow to-slidablyreceive; shaft I105 which'isrotationallydriven by shaft I09 through thexngaeement ;of.;a-p in fixed on-gshaft I with longitudinal :sl t in the hollow nortion of shaft I09. The upper endofshaftlflq is mounted for rotationxwithinan adjustment device I I0 havin a thread d portion II I engageable with the threads ,Of agnut I12 welded or otherwise fixed tothe;,stat ionarj framework I I3 of theapparatus. Since Shafts I and ID!) are axially movable with .respectto each other disc H18 may therefore be moved radially toward or away from the peripheryorcenter :of drive disc I Iitjby turning threaded portion I I Iwithin nut I I2 whereby the rotational speed of: feed rolls 9! and 98. may be varied. The

purpose of such --a variable speed drive is to change the tap strap length when employing different :widths of paper. Driving disc I06, keyed to, shaft- I 01, is rotated constantly by drive shaft 92'throu gh spur gears H4 and H5 keyed respectively to-shafts 92 and I61. A conducting strip severing means comprising a shear blade H6, positioned between thefeed rolls and platform-85 and vertically movable within stationary bladeguides II'Isuitably fixed to the apparatus framework, is provided to carry out the'conducting-strip'severing function as in the main embodiment.

A tamper H8 pivotally mounted at [I9 on block I for counterclockwise movement against the biasingaction of spring I2I is also provided. Block I20 is removably mounted on a projection I22 integral with or otherwise suitably fixed to shear blade II6. By means of wing nut I23, block I20, and the tamper may be quicklyremoved and reversibly remounted on projection I22 so that tamper II8 may swing clockwise vagainst its spring bias, the purpose of which will be explained hereinafter.

The cutting edge of shear blade H6 is normally biasedawayfrom conducting strip-94 and to gle -I I8 is biased away from platform '85 by springs vI'24interposed between stationary blade guides III vand-a'yoke orextension I25 fixed-to shearblade H6. .Springs I24 also bias a cam roller I26 mounted on crosshead I21, which is in turnflxed to yoke I25, into constant rolling engagement with. cam I28 mounted on shaft I41.

In contrast to'the Fig. .lembodiment feed rolls 91 and v98 .are completely circular and-oneend ofshaft I00, to which feed roll 88 is keyed,is rotatably mounted one pair 'of radiusarms I29 .fixedoto shaft I353 which in turn is pivotally mounted on..t-h e apparatus frame work. Spring I3 I, interposed between one of theradius arms and Ya portion of the-stationary framework I32 normally biasesfeed roll 98 toward the conductins strip 94and into cooperation with feedaroll 91. However, afeed r011 pushrod I33 ismounted ationeend'to yoke IZE andthe opposite or lower end is engageable with one of the radius arms I29 sothatwhen shear blade I I6 is moved downwardly'by cam I28, feed roll 98 is moved out of engagement with strip 94 and away from feed roll 91 against the bias of spring I3I. Although feed ,;roll 98 is positively and constantly driven, this movement is, nevertheless, permittedby the pin and slot coupling I34 and universal joint I -35 in Shaft II I10.

was the: case .in .theTFig. 1 embodiment, an

adhesive reservoir I36 containingv liquid adhesive therein is positioned between "the :shearing means .and platform .65. An adhesive :applica'tor disc I3! is also provided and mountedqfor rotation of at least a portion thereof :in :the liquidadhesive as better illustrated in Fig. :2a. Unlike the Fig. :1 embodiment, however, disc I 31 is completely circularand is keyed 'to ashaft I39 which is rotatably mountedcon .arpair .ofrardius arms I4i! fixed to a shaft -I4I :pivotally mountedontthe apparatus framework. Amam roller I142 is;mounted on the :upper endzofga push rod I43,-the opposite or lower'end. of'which is fixedly connected to one of-the radius .sarms I49. A coil spring I44 -mounted'around push rod I43 .andinterposed betweenicam roller :I42 and push rod guide I45, fixed .to :the stationary framework, biases adhesive applicator disc .13! into engagement with conducting. strip 94 r and roller I42 into engagement with a cam r146 keyed to shaft I531. To allow for, a. slight.movement of adhesive applicator disc on arms I40 away from conducting strip 94, shaft I39 is driven through a flexible shaft I41 which'is in turn driventhrough gears I48, vI49, and I50 by gear W2 keyed to shaft I00.

As to theoperation of the apparatus hereinbefore described, energization of ,the ;motor which drives shaft 92 will initiatemovement of mounting strip 82 in the direction of the 'arrow across platform 85 andfeed of an end of conducting strip 94 toward and transversely over the mounting strip as in the main embodiment. Adhesive applicator disc I3L-during a portion of-this feed willbe in engagement with the underside of the conducting-stripwhereby a narrow strip of adhesive material willbe applied thereto. While conducting strip 94 is still in motion, cam I46 will become effective to depress push rod I43 downwardly against the bias of spring I44 and disc I31 cut of engagement with the conducting strip. The portion :of the conducting strip thereafter fed toward the mounting strip represents that portion of the eventual tap strap which will project beyond the edge thereof. Shortly thereafter, cam I28 will become effective to start downward movement of shear blade H6 and yoke I25, whereupon further feed of conducting strip 94 will be momentarily stopped since push-rod I33 connected to the yoke will thereby depress radius arms I29 and feed roll 98 mounted thereon out of engagement with conducting strip 94. Upon further downwardmovement of shear blade IIS, the cutting edge thereof will pass through,"there by severing conducting strip 94. Simultaneously, tamperl I8 will be lowered into rolling and pressure engagement with the severed portion, whereupon the tamper will travel a short distance therewith counterclockwise about its pivot [I9 as was the case in the main embodiment. Then cam I28 will become effective to permit rise of shear'blade II6 under the biasing action of springs I24 and simultaneous rise of tamper H3 out of engagement with the moving tap strap, now firmly anixed to the mounting strip, whereupon the tamper is free to swing clockwise under the bias of spring I2I to its initial the .moving. mounting strip. .As the shear .blade and yoke I25 approach the uppermostposition of their travel, the raising of push rod I33 will allow spring [3| to move rotating feed roll 98 into pressure engagement-with conducting strip 94, whereupon the previously severed. end thereof will be moved into engagementwith the applicator disc I3! and then. over the moving mounting strip.

This apparatus, thus embodying a modification of my invention, is somewhat more flexible than the apparatus shown in the Fig. 1 embod ment in that both rolls for use on the righthand side as well as rolls for use on the lefthand side of the tap strap inserter machine disclosed'i'n the above mentioned copending application, Serial No. 18,104 may be made on the same machine. The operation hereinbefore described involved the assembly of a left-hand roll. To assemble tap straps on a right-hand roll, a supply roll or reel corresponding to supply roll 80 is mounted on spindle I60 corresponding to spindle 8| after which the mounting strip is pulled to the left instead of to the right across the platform 85 around friction roll Nil, corresponding to friction roll 81 for re-winding into a finished roll on radius arm I62 corresponding to radius arm I53. Before starting the actual assembly of such a right-hand roll, tamper support block I20 is removed from support arm I22 and reversibly mounted thereon so that the tamper will be free to move clockwise with and in the direction of movement of the mounting strip against the biasing action of spring I 2|.

While I have, in accordance with the patent statutes, shown and described a particular embodiment of my invention and a modification thereof including methods of operation together with apparatus for automatically carrying them out, other changes will be obvious to those skilled in the art; and I, therefore, aim in the appended claims to cover all such changes as fall within the true spirit and scope of my invention.
