Kile, Akron, Ohio; and Simon Kain, -Chicago} 111., assignors te -John Fast dz '00., *Ch-icago, Ill, a mor pbration :of :Illinois Application September 18, 1944;ISer'ial K035541506 The machine of the present .i-nvention-aconstitutessan improvement in :certain particuiars of the machine setforth and described in Letters Patent Nd-2,205,171, issued June .13, 1940., and
innits general character the present machine closely follows that of the patent referred to.
The machine illustrated makes provision for the winding of condensers Iromwebs of-metal 'foil andpaper which are tedin superposed re-lation fromspools soi-arranged as to deed to acommon lin iof advance, so "that a v laminated-composite strand-of foil and paper will be delivered to: a :mand-reL upon which the condenser will :be wound untilrit is built up to the desired dimensions, at which time the strips of -foil and paper will be automaticallyand successively severed so that the terminus of the toil wil-lilie withinthe .final paper-windings and be thoroughly protected thereby. The [strips of foil .may he slightlystagigered with respect to the paper strips-so that the edges. of the-respective -.foi1 strips will beoppositely protruded or exposed at the ends :of the condenser and-in position tohave the-heads of wire soldered thereto.
The present invention is directed more particularly to the means :providedior feeding forwardly .a hinder strip which is wound around the completed condenser to prevent'the unwinding ofithe same. In the patented construction, provision was made iorad-hering the terminus of'the outermostpaperwinding directly totheibody of the wound condenser, but experience has shown that the \stifiness. due/to theinumber and heavier .charaoter. of thepaper strips precluded th satisfactorn use of certain glues .or similar adherent materialsand that better results were. obtained 'by introducingthe leading end of a short section =0: paper strip into the terminal windings of the condenser so that its exposed end would extend more than onecfull turn beyond the end of the paper with the result that wheng'lue is applied, the paper strip will adhere to itself. 'The present invention makes provision for the feeding and adhering of such .a binder strip to a wound condenser or other wound-up roll ofstrip material. Further objects and details will appear-from the description of theinvention in conjunction with the accompanying drawin s, wherein:

The trams and-.mou'ntings for the ,Qpera'ting parts are substantially identical with those shown in the patent referred to, and-comprise a table 2i supported on suitable end standards '21 and carrying a vertically extending upperlframenor superstructure 2? which affords amounting for a series of .drums 23 carrying rolls of suitable insulating paperP; P P andP four'loeingishown in the present embodiment, although a greater or lesser number might he employed. "Themuper .fmmelalsoiserves as amountingiora pair of rolls of .a suitable foiTF, two of said .mus 'be'ingshown 'inthe present embodiment.
JAsflshown, the rolls of me't'a'lioil on eachside occupy an intermediate position with respect to the paper rolls, .so' that; in the ieedin i fol "(the composite i .strandirom which. the condenser is built up, there will ice .sizi layers or laminations, two paper layers occupying "the center position with. single layers o-f fioilion each s'ide thereof, and v with single layers of paper occupying the outermost positions. However, as the composite strand is wound uponitselfgthe single outerlayers of success'iveconvoldtions vwill overlie oneanother, so "that .in the completed condenser each strip of -.'oi1 will heaseparated by two strips of papers The edges of the respective strips of .foil may 'be offset s'lightly oppositely with respect to the adjacent edges of the-paper strips, so" that the .foil in the completed condenser will be exposed" at each end .ialthough thearespective foil strips throughout all portions of. the condenser are separated from one another.
' .The paper and foil strips lare fedidownward-ly over guide rolls 24120 be united into a strand which is wound upon adivided-mandrel 25.of-the character described in the patent aforesaid, .and "it is not here deemedinecessary to describe ,in'detall the construction .ofJlthe mandrel. The .foil strips are "fed from mnsi'r' whichrareroarriedeby spools 26 of the chara'ctershown ini'he patent,
and are restrained from overrunning by friction bands 21, which likewise need not be described in detail.
Provision is made for puncturing the foil strips by the passage of electric sparks discharged from needle points 28 and associated mechanism of the character shown in the patent referred to, the currentbeing'ch'arged into condensers 29 in the manner shown in said patent. Provision is also made for the discharge of the sparks which perforate the foil in advance of the severing of the paper strips by a knife blade 30, so that the paper strips will overlie and enclose the foil, but these features are fully set forth in the patent referred to, the cam 30a corresponding to the cam I92 of the patent for actuating connections of the character therein shown to time the knife stroke.
The binder strip B, shown in Figs. 8 and 9, is fed from a spool 3| (Fig. 2) mounted below the table 20 and carried upwardly through an aperture 32 and around an elbow-shaped guide member 33 provided on its rounded outer surface with a channel 34 for the reception of the strip, the forward end of which is entered within a channel 35 in an upper guide block 36 which cooperates with a lower guide block 31 in providing a closed passageway for the strip, so that the leading end thereof will be projected outwardly toward the mandrel and at a proper angle of elevation above the mandrel to bring the leading end of the strip into contact with the terminal portion of the advancing strand, with the result that the leading end of the binding strip will be caught within the bite of the terminal convolutions being applied to the condenser and wound up therewith to carry the binding strip around the completed condenser, as shown in Fig. 9.
The leading section of the binder strip is out free from the remainder of the strip through the action of a spring cutter 38, the downturned free end 39 of which terminates in a serrated cutting edge 40 (Fig. '7), which moves within a slot 4| in the upper guide block 36 and in register with a cross slot 42 in the lower guide block 31 across which the binder strip is carried. The opposite end 43 of the spring cutter is downturned and bolted to the upper guide block, the arrangement being such as to permit the free cutting end of the spring cutter to be forceddownwardly to sever the binder strip at the proper time. The severing of the binder strip is effected by the forward advance of the knife blade 35, which is positioned to strike through the composite strand of paper and foil at a point slightly behind the line of contact of the leading end of the binder strip, so that the terminus ofthe strand will be drawn down and folded around the end of the binder strip and both be Wound up together.
' In order to actuate the cutter 38 by the forward advance of the knife, the knife is provided with a rounded boss 44 which is positioned to engage a rounded hump 45 at the bend of the spring cutter, so that, as the knife advances, the cutter will be depressed at the proper instant to ermit the binder strip to be caught within the last convolution of the strand and drawn forward. As the binder strip is being wound up, it will be contacted by the upward thrust of a glue swab 45a which applies a spot of glue to the binder strip 1 before it is completely wound, so that the outermost turn of the strip will be sealed by a gluing device identical with that disclosed in the patent aforesaid actuated by cam 451) corresponding to cam 2 l 5 and connections therein shown.
The means provided for operating and timing the knife, and for lifting, rotating, timing and actuating the mandrel, and for removing the completed condenser therefrom, are all set forth in detail in the patent referred to. I
The binder strip is drawn upwardly from the spool 3| through the contact of a beveled friction roller 46, which presses the strip upwardly against an overhanging lip 4l-rearwardly extending from the upper guide block 36 and serves to shove forward the confined leading section of the strip. The roller 46 is mounted upon the end of a shaft 48, which extends through the wall of the upper frame 22 and is suitably journaled therein.
The shaft 48 has pinned thereon a rabbeted drum 49 provided with ratchet teeth 5|], which are adapted to be engaged by a spring pressed dog 5| carried by the flanged end 52 of a drum 53 freely mounted upon the shaft 48. The opposite face of the ratchet drum 49 bears against a friction ring 54 which is interposed between the ratchet drum and a plate 55, which is slidably mounted upon supporting rods 55 or the like outwardly extending from the upper frame. The end 51 of the shaft 48 is threaded to receive a thumb nut 58, which bears against the interposed spring 59, which applies pressure to the plate 55 to hold the friction disk in compressive relation against the outer face of the drum 49.
The drum 53 has wound thereon the upper terminus of an operating cable 60, and also has reversely wound thereon the upper terminus of a restoring cable 6| connected with a spring 62. The operating cable (Fig. 2) is carried downwardly around a pulley 63 carried by a lever 64 pivoted at its opposite end on a pivot rod 65 and carrying at an intermediate point a contact roller 66 which engages the edge of a cam 61 mounted upon a cam shaft 88 which corresponds to the cam shaft 15 of the patent referred to, which cam shaft carries the cams for operating the mandrel and knife, as described in detail in the aforesaid patent.
The cable 60, after passing around the pulley 63, is carried upward around a pulley 69, and thence downwardly to an eye 10 at the outer or free end of the lever 64, so that, as the lever is depressed by the high point on the cam, the upper end of the cable 60 will be drawn downwardly, thereby unwinding the cable convolutions on the drum 53, which acts through the dog 5| and ratchet to impart rotation to the shaft 48 and roller 46. At the same time the oppositely wound restoring cable will be wound up under spring tension, so that, when the lever roller 66 is released from the high point on the cam, the restoring cable will act to draw back the spring dog 5| around the ratchet drum, without, however, imparting reverse rotation thereto. This serves to feed forward the desired length of wrapper strip for severance as the knife 39 advances to out off the leading section in preparation for the next succeeding feeding movement of the roller 46.
In view of the fact that it is necessary to provide for the adjustment of the guide blocks 36--3'| in order 'to feed the binding strip to condensers of varying diameter, the guide blocks are mounted within a bifurcated yoke H, the prongs of which embrace the upper and lower guide blocks, as shown in Fig. 5. The yoke is carried by a stub shaft 12 entered through a bearing 13 and provided' on its end with a finger 14 which is split at its lower end '15 to embrace the end of the shaft 12 upon which it is clamped by the tightening of a screw 16. The upper end of the finger is engaged by acoil s ring W andas provided with an adjusting screw le-bearing A tan abutmerit 1 3-, whiehpermits --the shaft 1 2- to be rocked slightly to arrow necessary an'gular adiustment to "the feeding blocks to direct the-st1 iptthe desired position to-engage the terminal p'o'rti'on of the downwardly traveling 'strand of material.
"In "order to cause a rupture of "the strips or foil after the same have been pierced "by the electrio sparks rrom the needles 28, provisionis made for "applying braking pressure to the spools-which carry thefoil; through the medium of 'a cable -81], the action-0f which iscontrolled by -'a--p hotoelectric cell 8| which coacts with asource o'f-iii-umin'atiori 82; so that, as the line *of perforations in the foilpass through fihe liflej'df light transmission from the source to the ce ll, abe'am will be transmitted to thebell which controls the setting of the brakes on the spools, thereby rupturing the "foil in the manner "described in' the fiatllt previously referred to.
Provision isalso made f or raising and lowering the mandrel and associated mechanisms, but all of 7 these featuresare identical with the disclosures of said "patent.
Operation The'rolls of paper and foil are mounted upon the respective spools, andthe paper spools are adjusted "to stagger the-paper strips with respect to the foil strips; so that one edge of one of the 'fdilstrips "will protrude from one side of'the paper While the opposite edgelies Within the opposits margins of the paper, the companion 'foil strip being -similarly arranged to protrude beyond the opposite edges of the paper strips.
After accurate adjustment has been "made to feed the-paper and foil strips in proper relation, the mandrel will he lifted to engage the leading end of the composite strand, after which power is applied to begin the winding'operation.
At a timed period in the feeding operationthe sparks emitted from the" needle point '28 will puncture through the foil-strips to provide aweakened line of severence, and thereafter the application of a braking pressure on thefoil spools will prevent additional feeding and cause therupturing of the foil strips prior to the advance of the knife "3'0, which severs the paper and "completesthe cutting free of the composite "strand.
Prio to the advance of the knife, however, the leading end of the binder strip will be thrust inwardly by the action of the feed roller M; so that the binder strip will be caught within the convolutions of the strand and a proper length thereof out off and wound around the terminus of ithe paper strand to the extent necessary to cause the strip to be sealed upon itself by the ap plication of 'a glue spot, so that unwinding and disintegration ofthe completed condenser will be prevented; after which" the completed and sealed condenser will be discharged from the mandrel.
The throw of the lever 64, which is regulated by the cam Bl, will determine the extent of the feeding thrust imparted to the strip by the roll 46 so that a p oper length of the binder strip will be advanced and severed in preparation for the final sealing of the strip around the condenser.
The device is one which assure speed and accuracy in the performanoeof the operation required in sealing the wound up condenser and enables the employment of a sealing strip of the character best fitted for the purpose, irrespective scribed one whieh is particularly adapted to the winding and sealing bf rolled-up-'condensers,
it is not the intention mama the employment of the stri sealin features to maohines employed exclusively in the winding-of 'con'densers,since the sealing features maybe employed in the binding' andsealing of a roll of strip material i rrespecti-ve "of the-nature 'of the strips or the use for which-the roll is -in tended.
