Fig. 13 ma vertical section tmough the n uuow centers of a winding unit, showing; a core retained for Y 86 The machine illustrated herewith exempliiles an improved mode of textile strand manipulation characterized .by causing a winding strand package to travein a predetermined path inrelation to the machine while winding a strand -on the 8l package in overlapped layers which advance axially ofthe package. Typically this operation is performed simultaneously in' respect to a large number of winding packages; .a vp rocesslon'is thus' formed of 40 packages in all stages. oi' development from a freshly fed bare core to a completely wound packageready for doiilng. As illustrativ'epf the winding perfumed on any one of the traveling packages; the winding strand may be caused to traverse a portion of the package toform a layer .of short length, whereupon the rangeof traverse is automatically shifted axially of the package and another like layer wound. The illustratedl 4machine of the present invention provides for Il the automatic supply of empty cores to traveling core-holders at a predetermined part of their path about the machine-provides for automatically asfsociating supply strands with the serially replenished. core holders, provides for automatically Il Referring to Figs. 1 and 2, a suitable guideway for the various winding units of the machine may comprise upper and lower rails II and I2, each disposed in opposite straight and semi-circular runs, (Figi. 2) and supported by transverse frame sections I3, and longitudinal end frame sections I4 and I5, (Fig. 1).

Suitable means for conveying the several windy ing units of the machine along the rails I I and I2 may comprise an endless chain I4' (Figs. l and 2) running on opposite sprocket wheels I5 andl I6. Either of these sprocket wheels may be driven by any suitable connections, such for example asA those shown in my Patent No. 1,609,639; as illustrated hereinthe sprocket wheel I6 is driven by an electric motor 20, which is connected thereto by "leans of a belt 2|., pulley 22, (Fig.,2) a set of reduction gearing indicated at 23, and a pinion 24 meshing with internal gear teeth 25 on the sprocket wheel, as more fully explained inmy copending application, Serial No. 542,011, filed June 4, 1931. A suitable switch 21, having buttons 28 and 29 for starting and stopping respectively, is adapted to control the motor 20 and hence the progress of the windingunits about the machine. l y

Preferably-the several traveling winding units derive their power for winding from individual motors travelin:r therewith about the machine.

With this in View, the upper rail II of the machine frame preferably carries electric conductor rails 3|, 32, 33, herein shown as three in number, suitably insulated from the frame and adapted to supply current to the traveling units, as described in my copending application, Serial No. 508,868, led January 15, 1931, Patent No. 1,964,715.

Preferred general organization of a traveling winding unit An individual traveling winding unit preferably includes, like the machines of my above patent and copending applications, a main frame memberIIl (Fig. 4) adapted to bridge the distance between upper and lower guide rails II and I2, con- -iined to the lower rail by a pin 4I and roll 42, andcarrying at its top a head member 43. Upon this head member 43 are preferably provided horizontally`disposed spaced outer rol1sf45 and 46 (Fig. 3) and an inner roll 41 (Fig. 4) adapted respectively to run onV opposite faces of the upper rail II, and the whole unit is movably. supported on this rail by means of spaced vertically disposed rolls 48`and49 (-Fig'. 3) running on the top edge of the rail.

'An electric motor 52 is. preferably mounted upon two spaced horizontal inward extensions 53 and llniFig. 2) of the'head member 43. vCurrent for operating the motor 52 is preferably' conducted* thereto through brushes I3III2 and |33 (Figs.

4 and 5) carried by a rotatable shaft I3Ii on the carrier and adapted to press against the stationary conductor rails 3I, 32 and 33. From the brushes I3I, I32 and |33, suitable wires, not

shown, extend to the motor. The motor'52 is arlranged to rotate the winding package, a pre'- ferred driving connection to such package con-f sisting of a hollow center 55 (Figs. 5, 8 and 13) fast on the motor shaft and shaped to receive one end of a winding package core. Such core may be for example the typical filling or weft bobbin indicated at 51 in Fig. 4.

The other or outer end of the core is preferably heldin a revolving hollow center 60 mounted in ball bearings retained in a housing 6I. Means is preferably provided for moving the outer hollow center 60 toward and from the vinner center 55 to grasp and to release the cores successively handled by the unit. As shown in Fig. 4 the housing 6I for the outer center 60 is fastened by a bracket 62 to a rod 63 which is mounted for reciprocation in a sleeve 64 fast to the head portion of the carrier unit. A spring 61 acting on a pin 68 which projects down from the rod 63 through a slot (not shown) in sleeve 64 urges the rod B3 and outer housing to the left in Fig. 4, thus gripping the core 51 for winding. The inner end 63a of rod 63 preferably projects from the left of sleeve 64 in position to be engaged by actuating means (explained hereinafter) for controlling the position of rod E3 and center 60 so as to grasp and release the cores at predetermined positions of the carri-er yunit in`its path.

The traverse mechanism, such as will now 'be described, is preferably arranged to perform its strand distributing operation without imparting any substantial twist to the strand. Preferably this traverse mechanism derives its power from a pinion 10 on the motor s'haft, said pinion meshing with an internal gear 1I on the end face.` of a traverse cam 12. The casing of motor 52 may be extended, as shown, to enclose the cam 12. To provide a rapid traverse with a cam of small size, this cam is preferably of the crossed groove type, having a groove 13 in the form of reversed spirals crossing at 13a. A rod 16, carrying a traverse assembly 11 and mounted to slide in guides 18 and 19, has mounted at its left end a cam follower BI) adapted to run in the groove 13 of the traverse cam; operation of these elements imparts to the traverse assembly 11 a reciprocating movement along the axis' of the rotating core 51 within a range equal to the throw of the cam 12. In the form of the d evice illustrated herein, the traverse assembly moves from one end of its relatively rapid -reciprocating stroke to the other during the time required for twenty revolutions of the core 51.

Means is preferably provided for automatically shifting the range of movement of the traverse assembly to make the wound package consist of overlapped axially advancing layers, such means preferably acting in response 'to growth of the winding package. A preferred form. of such means'willnow be described by reference to the construction of the illustrated traverse assembly 11. Referring to Figs. '1, 7 and 8, the traverse assembly 11 shown therein includes a central rotatable tubular part 9| having internal threads 32 adapted to engage corresponding half-threads 93 on the reciprocating rod 1G. At opposite vends of tubular part 3| are two non-rotatable elements 95, 96 each cutaway to engage a. key 98 on the reciprocating. rod 16. These two non-rotatable Y yokes and |0I. 'I he vcentral rotatable tubular part 3| ofthe traverse assembly is provided with an enlargement in the form of a wheel I adapted to engage the surface of the last-wound layer of strand on the winding package when the tra-' verse assembly attains the inner or rear vpoint in its stroke. Contact of the wheel ||5 and the, rotating package in this way rotates the wheel I |5, causing its associated inner rotatable member 3| to turn a small amount on the threaded rod 10, thus ,advancing the whole traverse assembly slightly. This manner of advance of the traverse assembly is repeated each time suflicient strand is wound on a given layer. A wound bobbin is thus built with a very uniform diameter; the build" or advance of range of the traverse guide is automatically regulated by the growth of the package regardless of the count of yarn and speed of winding. i

The traverse yarn guide is herein shown .as comprising a porcelain knob |05, which is disposed over the Winding core 51 in position to receive a supply strand Y from beneath the' core, conduct the strand above the core and to deliver it downwardly to the forming winding on the core.

The porcelain knob |05 is preferably held on the outer end of an arm |01 vwhich is pivotally mounted at |03 on the upper yoke |00. AAn enlargement on arm |01 is normally acted on by a spring to hold the arm and'porcela'in |05in the full line positions of Fig. '1. The porcelain guide |05 is capable of vertical movementsuch that it can ride upon the surface ofthe winding package and is held there by its own weight and -by the pull of the strand passing over it.

The supply of strand for winding on a core is preferably carried on the individualtraveling carrier unit in the form of a wound package |20 retained on a suitable peg, spindle or other holder |2| carried on a bracket |22 extending .outward from the lower part of the carrier frame member I0 as shown in Fig. 4. From the supply, the strand passes upward through a suitable tension device |23 to the traverse guide |05.

Automatic stoppayes of winding Y (a) Upon completion of full package-The rof 'able abutment |42 positioned thereon so that may v be engaged by the traverse assembly 11 when the latter nearly reaches the rightend of` its@ travel which occurs when the winding operation is lsubstantially completed. Movement of the abutment |42 to the right by the traverseassembly 11 moves therod |I|-against ,the action of a spring |43,

(Fig. 4), disengaging the rod III from latch member |l3.. a`nd permitting rotatable rod |35. to remove the brushesy |3|, |32 and |33 from the rails 3|, 32 and33, thus stopping the motor 52. Thus during the travel `of, the carrier unit about the machine the vwinding operation is'-automatica1iy ystopped when the winding package attains av pre-A determined size.

(b) Upon breakage br exhaustion of the supply I strand..-The reciprocable rod |l|,'which acts to release rotatable rod |35 for stoppage ortho motor, has uvam; thereon at lso (Fig. 4) a rod Reciprocable rod Y series ofV cams |53 (Figs. 1, 2 andx4) disposed'rat 'intervals along the upper guide rail As indifcated in Fig. 2, eachof these spaced. cams |53 in- Y creases in'width in the direction of travel of the carrier units; the eil'ect of a cam |53 is to force outwardly the rod |5| of any of the carrier units engaged thereby, thus moving the reciprocable rod |4| to the right, releasing the rotatable rod |35 and-stoppingthe motor 52 in the same man.

ner as .in stopping winding of a full package. The'rod |5| is normally held clear of the cams |53 by a crank |50 (Figs. 3 and 4) forming part of a pivoted detector Wire |59 which rests on the strand runningfrom the tension'device |23 to the traverse guide |05. Upon. breakage or exhaustion of the strand, detector wire |59 drops to' the dotted position in Fig. 4, allowing rod |5| to drop into position for its end to be engaged `by the next adjacent cam |53, whereupon stoppage of the motor 52 occurs as just explained.

(c) At the end of a predetermined winding interval.-As is more fully explained below, winding 0n each of the traveling carrier units commences as soon as the individual unthas passed around the right-hand end of the machine.

end of a predetermined interval, which in the case of the present machine is the time required for the individual unit to pass around the machine and return again to the right-hand or replenishing end. By the provision'of suchfmeans winding ceases at this point,- even though the otlier stop devices described above have not as yetoperated.

In the illustrated machine winding may be stopped at the end ofv a-predetermined interval by an arrangement of the current conductors 3|, 32 and 3,3, such as l shown in Fig. 1, wherein these conductors end near'the right-hand end of the machine; upon reaching the end of these conducting rails, the motor 52 of the traveling carrier unit is deenergized and remains inactive until the carrier unit again reaches the start of these saine rails at a point indicated at 3| (Fig. 2)' just betfore a starting cam.21| described below. .If dej sired, the rails 3|, 32, 33, may merely be provided with deenergized sections extending around the' |5| of a length sui'ilcient to eng-age anyone of a.

Means is provided for automatically stopping winding onv any of the the traveling vunits severally at the right-hand end ofthe machine to vthis point 3|n ina manner similar to that disclosed in my copending application Serial No. 508,868, led I' January 15, 1931.

Automatic holding 'and releasing of winding package vcore and collection of full packages YIt has" beendescribedabove how, lduring its travel along the' guide rails, eachunit holdsv a winding package core'51 between-a live center 55 and an outer dead `center 50, which later is carried by bracket 62 on a reciprocable rodf63. Means is provided for. automaticallycausing the carrier unit to release its core'51 ata predetermined point in its travel. As' indicated in Figs.

l, 2 and 4,a xed vertical post |10, coaxial with the sprocket I6, may carry a cam H 'of such shape and position as to engage the inwardly extending end 63' of thereciprocable rod 03 of each carrier. Upon contacting with this cam |1| the-reciprocable ro'd 63 of thecar'rier is forced outwardly, (to

the right in Fig. 4) carrying the bracket 02 and .outer center 3,0 with it, thus releaslng'the winding package core' `51. This operation will take place v whenever the carrier unit passes slightly beyond the position of the single unit'shown in Fig. 2.1

AIt will be observed that uponrelease of the core 51'(usual1y carrying a full wound package) the strand extending from the supply |20 is still unbroken. Means is preferably provided for detaining the released core and package on the traveling 1, 2 and 4) disposed to close the outer lower ends of the troughs until the carriers reach a point somewhat beyond the extreme semi-circular end of the machine. Upon reaching the end of this guard plate |13, a full package or partially wound core in the trough |14 of the carrier is free' to slide out the end of the trough and into a receptacle |16 suitably positioned. 'I'hus the machine provides for delivering all of the released wound packages at a predetermined part of the travel of .the several units.

Automatic supply of winding package core The means provided in the present machine for holding and supplying fresh winding cores to the carrier units is shownv as comprising a magazine |80v (Fig. l) which may conveniently be mounted in part at least upon a bracket |'8I carried by a vertical support |82, the magazine being positioned approximately in prolongation' of the longitudinal axis of the machine. The exact construction of the magazine will of course vary with the particular kind of winding core to be employed bythe machine; for the type of core illustrated the mag-azine preferably utilizes inclined rods |84, |85, spaced at a suitable distance to hold the cores by their larger head ends with their smaller ends depending as indicated in Fig. 1.l The cores slide down thetwo rods' |84 and |85 until they are engaged by spaced arcuate plates |36 and |81 on both sides and their tip ends rest upon a curved portion |68 of the bracket I8|. The arcuate plates |86 and |81 vare fastened together by a U -shaped strap member |89 connected at its-twoends to the bracket I8 The closed end of this U-shaped strap member |89 is connected at `|9Il to an arcuate plate |9| which in turn is carried by a bracket |92.

The lower portion of the magazine includes an arcuate plate |95 hinged at |96 to the plate |9I, and a U-shaped member |99 integral with the arcuate plate |95, (Figs. 9 and 10). Fastened 'on both sides of this swinging member |99 are downwardly extending spring fingers. 202, 2023, each approximately in prolongation of the plates |86 just above them. The magazine includes also another U-shaped member |99 pivotally mounted at 200 on the bracket |6| sc as toswing about the same inclined axis as the U-shaped member |99. Spring fingers 203, 203a fastened on member |99a extend generally in downward prolongation of the upper plates |01. ' Ihe spring ngers 202, 202a and 203, 203a preferably have their lower -ends slightly inturned as shown in Fig. 10, yieldingly to hold the lowermost core of a stack in the magazine, as shownin Figs. l1 and 9: The position of the magazine is such `that the lowermost coreof the stack thus held is in position te be cleared both by the live center' 55 and the outer dead center 60,'when this outer center hasA been forcedto its outermost position by the gagement of acore 51.

action oi' the cam |1|; furthermore, the lowermost core 51`of the magazine is held at ,the 'appropriate levil to be engaged between these two centers and 60qof a passing unit 'when the outer dead center is forced inwardly toward the live center 55.

For causing the lowermost coregof the magazine thus to be engaged by the core-holding centers on va winding unit, the cam |1| which has previously held the dead center out, abruptly ends at 205 (Fig. 11) allowing .the spring 61 to force the center inwardor to the left, thus grasping the core 51 rmly between the two centers. Further movement of the traveling carrier beyond this point causes the lower hinged portions |99,

|99a and the spring lingers 202, 202a and 203, 203,

to swing about the pivots |96 and 200 until the core 51 is withdrawn from these spring lingers; v

the spring fingers retain all the remaining cores -in the magazine and the hinged lower portions of the'magazine swing downward into position to supply a core to the next traveling winding unit.

The pivotal mountingsof the lower parts of the magazine are` of advantage in allowing the relative motion of the core-holding centers 55 and 60 with relation to the magazine to withdraw a core from the magazine. In addition, such pivotal mountings allow the spring fingers 202, 202B, 2,03 and |13a to swing to permit the reciprocable rod 16 ofthe traveling unit to pass thereunder Without interference. although mounted to swing on a common axis, preferably have freedom for independent motion about pivots |96an'd 200 because of the fact that the outertip end of a core moves on a greater radius than the inner end of the core -at the curved end of the machine; the pivoted sections of the magazine which retain the two ends of the cores will therefore not move exactly together.

Automatic cessation of travel of the units-upon exhaustion or stoppage of the magazine unit will travel farther than usual to the left when the end (i3a of rod 63 is released by the end 205 of the cam |1|. A push pin 2| (Fig. 11) operating a piano wire 2|2 in a flexible conduit 2| 3 is disposed immediately beyond the end 205 of the cam |1I. This push pin 2|I is normally cleared by the end |53a of the rod 63 when rnove-r ment of the rod 63 has -been checked by `the en- Movement of the rod 63 to a greater distance to the left when the unit fails to engage a core forces thispush pin 2|| and the piano wire 2|2 inward. Ihe opposite end of the piano vwire carries. a pin 2M (Fig. 1) disposed in position to strike and operate the stop button 29 of the push button switch 21. This mechanism thus detects the failure of the magazine to supply a fresh core to a traveling unit, and upon the detection of such failure deenergizes thev motor 20 and thereby stops the traveling motion of the vari-:ous carrier units. In addition, to ypreventing idle movement of the machine i'n the absence of an available supply of fresh cores this mechanism also serves to prevent any carrier unitfrom traveling far `enough to discharge its wound package until a fresh core has been placed in Winding .position in the unit.

Exhaustion of the supply of winding-cores thereamonio the carriers' to continue Atuen wound packages after an exhaustion or stoppage ofV supply of fresh cores.

Automatic association'of the supply strand with i the fresh winding core The machine in its preferred forms is capable of automatically associatingl the .supply strand whichV travels with the given carrierI with thev fresh core without the necessity for any prewinding on the newly suppliedcore or for any tying of knots.'

It will be ,observedY that the location of the porcelain guide eye |05.is such that when the bobbin is released from its centers and dropped into the trough |10, this porcelain eye |05 retains'the `run of yarn extending from the tension device |23 to the wound bobbin; itis preferably Vthis portion of yarn extending from the porcelain -guide eye v|05 to thecompleted released bobbin which is associated with the newly supplied core; thus the traverse guide eye |05, tension device,

-and any other instrumentalities acting on the imparting a winding rotation to such a strand presented thereto so that this portion of the strand, placed in engagement with the hollow center 55, will be caused to wind up upon a core newly placed in the center 55. As shown in Figs.

5 and 8, the center 55 is preferably provided around its rim with toothed serrations 220 forming notches acrosswhich the'- yarn Y 'may be laid as shown in Fig. 8.- A strand thus laid across the serrations in the hollow center 55 will be so posi- 4 tioned as automatically to be gripped between the center 55 and a new core 51when the core 51 is forced endwise against the-center 55' by the outer center 50. In this way the strand leading from the supply |20 can be automatically associated with the new core. I

It will be understood that traverse assembly 11 of the unit progresses relatively slowly towardV cally to carry the strand extending from the porcelain guide'l05 over into engagement with the serrations 220 of the hollow center 55. As previl-v ously described the traverseassembly includes an arm |01 pivoted at |00` and normally held in the full line position of Fig. 7 by. a spring This I cam 23|, (Figs. 1 and 2) for moving the traverseA arm |01, which serves to hold the porcelain guide |00; preferably includes an upturned portion 230 (Figs. 5, 6 and 7) adapted to cooperate with a stop asembly to the left. This cam 23| whlchmay conveniently be carriedby arms 223 and 230 extending from the vertical post |10 is so positioned'as to engage the upstanding extension 230 on the arm |01 soon after `the full package has been released bythe center 00. Further move.

ment of the carrier around the end of the maarm |01.

chine turns the arm |01 to its dotted'position in Fig. 'l and moves the entire traverse assembly 11 to its' extreme left-hand position on the rod 15 by this engagement of the; extension 230 with the cam 23|. In order to release the traverse assembly from the threads 93 on the rod 15 during this movementl to theleft the pivoted arm |01 preferably carries a shoulder' |01 (Fig. 1) adapted to strike a rim ||5a of the wheel ||5. When ,the extension' 230 is struck by the cam 23|, and the arm |01 -thus swung to the dotted line position of Fig. 7, the portion ||l1a of this arm striking the rim ||5EL forces the wheel I I5 to the right in Fig. 7 transversely of the rod 15, and disengagesthe threads 92 on the tubular part 9| from the corresponding threads 93 on the rod 15. The traverse assembly isthus free to slide along the rod 16 under the influence of the cam 23|. Upon arrival at the left-hand end of the rod 1G the arm |01 and its attachments still occupy the relative position shown in dotted lines in Fig. 7; in this way,` the porcelain4 eye |05 and the upturned extension 230 are moved past the serrated hollow center 55 and clear the magazine |00 and its retained bobbins.`

This movement of the traverse assembly to the left is preferably utilized to'assooiate the strand Y extending down from the porcelain eye |05 with the serrated hollow center 55.' For this purpose the traverse assembly preferably carries a wire 240 having a horizontally disposed arcuate portion 20| (Fig. 8) below the level ofthe hollow center 55, and a Vertical portion 242 pivotally mounted to turn about a vertical axis in a loop 243 carried by the traverse assembly. At its upper end the wire 200 is provided with a crank arm 244 which is slidably engaged in a slot 245 in the The relations of `these parts are such that-when the porcelain eye |05 occupies its full line position in Fig. 7, the Wire 240 is clear of thc path through which a full package drops in being released` by the centers 55 and 60. When the arm |01.is swung to its dotted line position in Fig. 7 by the action of the cam 23|, the Wire 240 swings vthrough an arc of about 120, as shown by the dotted position of this arm. (Fig. 7). During this movement the hook-shaped outer portion 24| of the wire engages the strand which now extends downward fromthe porcelain eye |05 to the released package. Movement of the traverse assembly to the left along the rod 16 (Fig. 4) causes the arm-200 to carry the yarn Y to the left: the porcelain eye |05 and-the wire 240 engaging the yarn above and ybelow the serrated hollow center 55, respectively, place the yarn across this center as shown in Fig. 8.

After this sequence of operations the traveling unit reaches the magazine |80, at which point a fresh bobbin 51 is grasped between the centers 55 and`50 as described above, the head end of'd the bobbin securing and clamping the strand against the live center 55.

Automatic severing of the supply strand from the wound package 'rol extreme inner or left-hand position. Upper blade- 250 is preferably pivoted tc the lower blade at 252 and carries integral therewith an inwardly extending crank arm .252.- IIl'he head portion of the carrier is pwvided with a depending pin 254 disposed in position to engage this arm 252 in passing and to turn the upper blade 252 so as to sever the yarn. A suitable spring 255 then returns the scissors to their open position ready to operate upon the yarn of thenext traveling carrier unit.

Resettinp of traverse mechanism in position to wind AfterY clamping the strand between the new core and the-hollow center 55 and severing the completed package' from this strand, the-traverse guide |55 is automatically carried over to the yarn receiving portion of the core in position for winding to commence. For this purpose there is preferably provided a cam 255 (Fig. 2), conveniently mounted integral with one oithe supports 224 of the cam 23|.,-this cam' 255 projecting into the path traversed by the upper projection 22| of the traverse assembly. Uponcontacting with this cam 255, the projection 235, the arm |01 and yarn or the completion of a full package) soasto porcelain guide eye are returned to positions such as are shown inV vfull lines in Fig. 7. `'111e cam 25| is so positioned with respect yto the position o! a new core 51 as to leave the'porcelain eye |55 at approximately the head end o'f the core in position to starta layer of winding at this end. Meanwhile the end of the yarn Y which extends over the porcelain eye'i55 remains anvchoredbetween the end of the core 51 and the hollow center 55 so that when the hollow center 55 begins to tum-the yarn is drawn onto the rotating core.

When the arm |51 and eye |55 are -returned to their full line positions in Fig. 7 to start winding, a .projection |51h on arm- |51 contacts with an inner surface of the rim H5* onthe wheelY H5 and urges the associated threadedbarrel 5| into engagement with theA machine from that shown in Fig. 1, a resetting A mechanism acts to restorebrushes |2|,`|22, |52 into position sutrlas shown 1n Fig; 4, 1n with these rails. AIt will be understood l.that in the case of most 'of the carrier units', the-rod |25 will previously have been rotatedl (either as' a consequence of breakage vor exhaustion of the remove thebrushes from contact with their To restore the brushes into-contact withthe rails the crank arm 21| is ,provided on the lower end of rotatable rod |25lin position to engage a cam 21| located at the beginning of the conductor rails 2i, 22 and 22 on the far side ofthe machine.

When thev crank arm 215 encounters this' camit is rotated thereby in a direction opposite'vto that induced by the spring |25. This rotates the vertical rod |25 and the brushes into position to contact with the conductorv rails. The latch' member Hf'which has occupied a'position behind the rod ill, (when these parts are viewed 4, Bland v6) BOW forces this rod lll slightly to the right by acamming action and its end' allowing `this rod to snap in position equivalents which fall v as to be moved therewith as the rod 15 reciprocates under A'3.Ina

By the time the 4crank arm 215 4leaves the cam.v

surface 21| the motor 52 will have started, the

strand'will be winding upon the.fresh core 51.

and the portion of the strand engaged by the detector a'rm |55 will'be under tension so that the brushes |2|l |32 and |23 will not again lbeldisengaged until some condition of breakage oi` exhaustion of the strand occurs or a iull package is completed. The last stop-motion.

cam |53 on the side -of the machine shown in Fig. l is preferably extended around the curved end of the machine'to .a point |53b just beyond the starting cam 21| ln the form of a ledge |52!IL ontop of which the stop-motion` rod Ill canl ride. This rod Ill is thus supported during the time in which thereis no winding tension on the supplystrand.

- Since the various operations incident to the automatic control of winding and to the automatic replenishment andinitiation 'of windingl havebeen described ,for one of the several traveling carrier units, n o further description of the operation of the machine as a whole is deemed 1t should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modications and vwithin the scope of the appended claims. y
