JONES, OI PROVIDENCE, RHODE ISLAND, ASSIGNOR TO UNIVERSAL WIND- ING"GOMPANY, OF BOSTON, MASSACHUSETTS, A CQRIORATION OF MASSACHUSETTS "WINDING momma Application filed August 9', 1928. Serial no. 298,518.

This invention relates to improvements in winding machines for winding silk, rayon and other delicate strand materials to produce splicer bobbins for use in knitting machines. The improvements. are directed particularly to that type of machine in which the strand material is wound on a tapered or inclined chase to build a bobbin of generally cylindrical form having a conical or pointed nose from which the material delivers.

One object of the'invention is to provide a winding machine having means for rotating the cop or bobbin and means for traversing the strand material on the tapered chase thereof, with the traversing-means or guiding-means adapted to follow the inclined surface'on which the winding is performed without contact therewith.

Another object of the invention'is toprovide means for holding the guiding-means or t hread-guide'in close proximity to the surface on which the winding is performed, to, insure an accurate disposition of the coils of winding, while avoiding contact of the guide therewith to prevent abrasion or chafing of the delicate strand material.

' Another object of the invention is to provide a controlling-device for oscillating the thread-guide which is operated automatically from the reciprocating movement of the guide Without the use of intervening means such as cranks, eccentrics or the like.

Another object of the invention is to provide a controlling-device for the traversingmeans or thread-guide which may be applied to winding machines of standard types without material change in the construction or arrangement of the parts thereof.

Another object of the invention is to provide a controlling-device for the travers1ng-= means which is adjustable to properly regulate the action of the thread-guide in windingv cops and bobbins of different sizes and shapes.

Another object of the invention is-to provide a device of the type specified which is simple in construction, eflicient in act-ion and of order. I

-Further objects of the improvement are set forth in the following specification which proof against derangement and getting out machine showin of the thread-guide controlling-device;

- Fig. ,6 is a fragmentary perspective view showing a modified form of the track or rail as provided with adjustable means for regulating its oscillating movement; and

Fig. 7 is a perspective viewof the element which acts torock the track to oscillate the thread-guide. I p In the present drawings the invention is illustrated aslapplied to use on a winding machine of well-known type comprising the main elements of a rotating winding-spindle, 0

a reciprocable thread-guide, and means for reciprocating the thread-guide to adapt it to traverse the strand material on the cop or bobbin. In other cases, however, the machine may tomprise means for longitudinally reoiprocating the winding-spindle instead of the thread-guide, and still other forms of construction of the essential elements of the winding-mechanism may be employed which would fall within the spirit and scope of the present invention. In the present type of machine the thread-guide is adapted to oscillate on its axis of reciprocation, 'whereby it is caused to follow the tapered surface of the winding, and means are provided for feeding the guide longitudinally of the bobbin to rogressively advance the layers of winding rom base to tip of the bobbin. In other types of machines, however, the advance or ste ping forward of the layers of winding may e accomplished by moving the winding-spindle in an aixial direction with respect to the threadgui e.

In Figs. 1 and 2 of the present drawings, 2 designates a box-like frame on which the various elements of the winding-mechanism are mounted, and 3 is the rotatable windingspindle shown as journalled in suitable bearings 4 at the top of the frame. A cam-shaft 6, arranged below in parallel relation to the winding-spindle 3, is journalled in bearings 5 on the sides of the frame 2, and carried thereon to be driven thereby is a helical traversecam 7. The winding-spindle 3 and cam-shaft 6 may be connected to be rotated, one from the other, through the use of pulleys, gears or the like, not herein shown, the machine bein driven from a suitable source of power suc as a motor or counter-shaft, not shown.

The winding-s )indle 3 extends be 0nd its hearing at the si e of the frame 2 an is revided with a suitable mandrel or cop-ho der for sup orting the bobbin-receiver or tube C on whlcli the winding is to be performed. As herein shown the winding-mandrel or copholder 8 is of generally cylindrical form, being provided at its inner end with an enlar ed frusto-conical boss 9 for receiving the 1101 ow tapered butt 0 of the paper bobbin-receiver or tube C. Any suitable means may be-employed for holding the bobbin-receiver or tube C on the mandrel 8, this device not being herein shown or described as it forms no part of the present invention.

Supported from the cam-shaft 6 of the machine is a traverse-frame 10, on which is slidably mounted the traversing threaduide 25 to adapt it to be recipro'cated longitudinally of the winding-spindle 3. The'travelse-frame 10 is constructed with a horizontal cross-bar or member 11 having opposite depending arms 12 and 13 formed with hubs 14 and 15. The hubs 14 and 15 are bored to receive bushings 16, held fixedl in the bearings 5 on the frame 2, and in w ich the cam-shaft 6 is {ournalled to rotate.

A longitudinal y-extending groove 17 in the cross-member 11 of the traverse-frame 10 provides a horizontal trackway for a slidable bar or rod 18. One end of the rod 18 is connected to a cross-head or slide 19 which carries a stud or roller 20 engaging in the helical groove 21 of the cam 7. It will be noted by reference to Fig. 2 that the cam 7 is secured fast on the camshaft 6 by means of a key 22 and the rotation of the shaft turns the cam to reciprocate the slide 19 and rod 18.

The opposite or forward end of the rod 18 carries an upright arm 23 connected to a parallel sliding rod 24, see Figs. 2 and 3, which constitutes the traverse-bar for .reci rocatingthe thread-guide 25. As shown in the present drawings, the traverse-bar 24 is mounted to slide in bearings 26 and 27 formed on a supplemental frame 28 attached to an overhangin portion 29 of the main traverseframe 10. li teferring particularly to Figs. 2 and 3, the supplemental frame 28 is constructed with a rail or bar 30 clamped to an upstanding flange 31 on the overhanging portion 29 of the traverse-frame 10 by means of screws 32. The lower edge of the rail 30 overhangs the groove 17 in the cross-bar 11 and portion 29 of the traverse-frame l0 and is formed with an arcuate bearing face abutting the side of the rod 18 to hold the latter in lace in the groove, see Fig. 3.

he traverse-frame 10, as before stated, is swiveled to swing on the axis of the camshaft 6, being thus mounted to adapt it for adjustment to set the traverse-bar 24: in proper s aced relation with respe'ct to the axis of t e winding-spindle 3, this adjustment bein altered for winding bobbins of different dlameter as hereinafter more fully explained. The traverse-frame 10 is normally held in fixed position by means of a detent lock shown in detail in Fig. 3. Referring to Fig. 2, a horizontal rod 33 extends through the side of the forward arm 12 of the traverse-frame 10, being further supported in a lug 34 at the end of the traverseframe extension 29 and also in a lug 35 at the outer end of the supplementary frame 28. The rod 33 is rockable in its bearings and carries a weighted detent-arm 36 secured in place thereon b means of a set-screw 37, see Fig. 3. The etent-arm 36 is formed on its inner side with a detent-lug or latch 38 which is engageable with a shoulder 39 on a fixed locking-member 40. The lo'ckin -member 10 is of arcuate form and provide with a slot t1 for receiving a bolt 42 by means of which the lock is fixedl clamped to the side of the frame 2. The ocking-member 40 may be adjusted in position by loosening its bolt 42 whereby to properly locate the detent-shoulder 39 to hold the traverse-frame in fixed position with the traverse-bar 241 in predetermined relation to the winding-spindle 3.

The lug or latch 38 on the detent-arm 36 may be released from the detent-shoulder 39 by rockin the arm 36 u wardly through the means 0 the rod 33; t is release of the detents being'efie'cted automatically when thewinding of a bobbin is completed whereby to permit the traverse-frame 10 to swing away from the winding-spindle so that the bobbin may be more readily dotfed therefrom. For thispurpose the rod 33 carries Elli an upright lever 43', see Fig. 2, which has an inclined upper end 44 adapted to be engaged by the thread-guide 25 when the ide has been fed out to the end of the bob in. The lever 43 may be adjusted ldngitudinallyof the rod 33 to cause it tobe engaged by the thread-guide 25 when the latter has been fed outwardly along the traverse-bar 24 to a predetermined extent in winding a bobbin of the required length. J

As before stated, the traverse-bar 24 is reciprocated on the supplemental frame 28 and, as shown in Fig. 2, the bar slides in bushings 47 driven into the bearings 26 and 27 on the frame. At the outer end of the frame 28 the bearing 26 is extended'to pro.- vide a guard for the end of the bar as it slides to its extreme of traverse. v

' Referring to Fig. 3, the arm 23 which connects the traverse-bar 24 with the lower rod 18 has an offset or bent portion 48 fixedly held in a slot in the rod. At its upper end the arm 23 is bent around at 54 to encompass the traversebar 24 and is clamped thereto by means of a screw 49. The screw 49 serves a" further purpose in providing means for attaching an element'of the guide controlling device to the arm'23, as will be later explained. 5

Referring to Fig. 4, the traverse-bar is of usual construction, being provided with v screw-threads 50 cut into its side in eccen tric relation to its :axis. The screw-threads are adapted to engagev corresponding" threads on the interior of a cylindrical nut or sleeve 51 which is rotated to advance or feed the threadrguide 25 longitudinally of the traverse-bar 24. The sleeve or nut 51 extends between and is straddled by the legs 52 and 53 of a bifurcated thread-guide holder 55, the ends of the legs being provided with bearings 56 and 57 swiveled on the bar 24 to adapt the holder to" oscillate about the axis thereof. The thread-guide proper may be constituted by a grooved, porcelain roll 58 secured to the outer end of the holder by means of a screw or stud 59.

On the sleeve or nut 51 is a flanged disk 60. to the side of which is attached a; contact- 'wheel 61; The contact-wheel 61 has a flanged peripheral rim adapted to make contact with the surface of the winding on the bobbin whereby to turn the nut 51 on the bar. 24. The periphery of the contact-wheel 61 makes contact with the base of the conical chase of the winding at each rearward stroke be moved laterally to disengage'its threads from the threads onthe bar whenfit is re-'- quired to release the nut to adjust the thread guide 25 to first position at the st artof the winding. The nut 51 is normally held in eccentric relation with respect to the axis of the bar 24, to maintain engagement between the threads on the bar and nut, by

means of a spring 62. The spring 62 has a coiled portion 63 with an arm 64 reaching outwardly therefrom and bearing against the rim of the disk on the nut 51. The construction and arrangement of the parts last described is substantially the same as generally employed on bobbins and cop-winding achines in 'which the thread-guide is advanced longitudinally of. the winding-spindle to deposit the yarn in forwardly-stepped courses laid on an inclined or conical chase.

As the thread-guide 25 is reciprocated longitudinally of the winding-spindle 3- the thread-guide holder or arm 55 is oscillated about the axis of the traverse-bar 24 to adapt the strand-feeding or delivering portion of the guide to follow up and down the inclined chase of the bobbin being wound. In previously used bobbin-windin machines of the present type thethread-gui e is designed to bear against the surface of the windingto direct its course up'and down theinclined chase of the bobbin. It has been found, however, that in Winding certain materials, such as silk, rayon and other delicate arns, the contact of the guide, with the sur ace of the bobbin-causes a chafing and abrasive action which has a deleterious effect on the material. That is to say the rubbing action of the guide on the bobbin chafes and roughens the material and spoils the finish of the yarn. It is therefore a prime object of the present improvement to eliminate this hafing or abrasive action of the guide on the material, an to this end means are provided for controllin the movement of the thread-guideto cause 1t to follow the chase of the bobbin Without contact thereon. In the present form of construction of the invention the means for controlling the movement of the guide consists of a device for oscillating the thread-guide holder 55 on the traverse-bar 24 during the reciprocatory motion of the guide in a certain predetermined path. The

guide-controlling device is operated from the traversing-means synchronouslytherewith. and a referred'form of construction of the mechanism employed for this purpose will next be described. 7

Referring to Figs. 1,2 and 3, the thread guide controlling meanscomprise a rockable guiding-track 67, preferably constructed in Y the form of a sheet-metal yoke orbifurcated frame as illustrated in perspectiveview in Fig. 5. The frame 65 is constituted by a longitudinal bar 66, preferably of angle-iron shape in cross section to provide an overhang- "ear s 69 provided with holes 70 whereby the frame 65 may be 'rockably mounted on the ing rail ortrack 67. Laterally-extending armsGS-at the ends of the rail 66terminate ly bent forward end 78, through which the tion 74 is formed with a cam-slot ends of the bushings 47, before referred to as held in the bearings 26 and 27 on the supplemental traverse-frame 28.

At the inner end of the frame the rail 67 is extended downwardl in an arcuatelyshaped triangular portion 74, see Fi s. 3 and 4, disposed in concentric relation wit res ect to the axis of the traverse-rod 24 on w ich the frame is swiveled. The dependin por- 5 inclined downwardly from the horizontal and adapted to receive a sliding stud or pin 76 pro ecting forwardly from an elbow-shaped arm 77 carried by the traverse-bar 24; As herein shown the arm 77, illustrated in detail in Fig. 7, is provided with a downwardpin 76 is riveted; and its rearward end is bent over to adapt it to overlie the top. and side of the traverse-arm 23 which, as before explained, is clamped around the traverse-rod 24. The depen ing rearward portion 79 of the arm 77 is formed at its lower end with a right-angled lip 80 projecting forwardly toward the traverse-arm 23 and slotted at 81 to adapt it to straddle the sides thereof. In the portion 79 of the arm 77 is a hole 82 for receiving the screw 49 which clamps the bent end 54 of the arm 23 to the rod 24. Lugs 73 roject forwardly from the rearward. ortion 79 of the arm 77 to bear against the ack of the arm 23 and when the screw 49 is screwed into place its head will bind against this part of the arm 77 to clamp it securely to the arm 23, the slotted lip 80 preventing the arm 77 from turning or skewing out of position.

It will now be apparent that when the traverse-bar 24 is reci rocated in the guideway of the frame 10 with the arm 77 moving therewith, the in 7 6 will be carried back and forth longitu many of the cam-slot 75 in the frame 65. As the slot 75 is inclined from the path of travel of the pin 76 the sliding movement of the latterin the slot will have the effect to rock the frame 65 on the axis of the traverse-bar 24. The alternate rising and falling motion of the rail 67 on the frame 65 is caused to oscillate the thread-guide 25 to carry its delivery point toward and awa from the axis of the winding-s indle 3. This action is accomplished throng the means of a sliding connection between the guide-holder or arm 55 of the guide 25 and the rail or track 67 of the frame 65. For this pur ose the guide-holder 55 is provided with a nger 83 rojecting rearwardly from its leg 53, see igs. 2, 3 and 4, and bent around to form a shoe 84which is adapted to hook around and straddle the rail 67 on the frame 65.

It will be understood that in the form of construction of the frame 65 as shown in 5 the cam-slot 75 is inclined to the horizontal path of the pin 76 at a predetermined angle to cause it to impart to the frame 65 the proper extent of rocking motion to carry the thread-guide 25 from a osition adjacent the outer circumference of the bobbin being wound, as illustrated in full lines in Fi 3, to a position contiguous to the surface 0 the cylindrical barrel 0 of the bobbin-carrier, as indicated by the dottedv lines in this view. To adapt the winding machine for winding bobbins of different proportions, however, it is desirable that the controlling-device be provided with ad'ustable means for altering the extent of osciilation of the thread-guide, and for this purpose a modified form of the frame ma be employed as illustrated in Fig. 6 of the rawings. As here, shown the camslot or trackway 85 for the pin 76 is formed in a separate member or arm 86 which is pivotally connected to the end of the rockable frame 87 by suitable means such as the screw 88. At its 0 posite end the slotted member 86 is rovide with an arcuate slot 89 through whic extends a screw 90 screwed into an ear 91 defiendingvfrom the rail 92 of the frame 87. y loosening the screw 90 the outer end of the member 86 may be swung u or down on its pivot to adjust the inclination of the cam-slot 85 to regulate the extent of throw of the thread-guide 25 in accordance with requirements in winding bobbins of varying sizes or proportions. The frame 87 may be substituted for the frame 65 without other alteration in the construction of the machine and its method of functioning to control the oscillatory movement of the thread-guide is the same as previously explained.

The method of operation of the complete machine is as follows: The paper tube or other form of bobbin-receiver C is placed on the mandrel 8 of the winding-spindle 3 and the end of the yarn or other strand 3/ leading from the source of supply, not herein shown, is attached to the tube in any suitable manner. The strand y may lead from a supply arranged below or, as shown in the present drawings, it may draw downwardly from a swift, spool or the like placed above the machine in any convenient location. The strand 11 is carried around the porcelain roll 58 as it draws to the carrier C on the winding mandrel whereby it will feed from the guide di rectly to the surface is to be performed.

Before starting the machine the traverseframe 10 is set in the osition illustrated in Figs. 1 and 3 and 100(6d in place with the detent-lug 38 on the latch 36 engaged with the shoulder 39 on the member 40. The thread-guide 25 is then adjusted to'starting position by sliding it back onthe traversebar 24 until the center of its roll 58 alines substantially with the rearward end of the base 0 of the bobbin-carrier C, the adjustment of the guide to this position being accomplished by releasing the nut 51 from the threads 50 'on the bar 24 in the manner as previously explained. The adjustment of the threadon which the winding 7 guide 25 to starting position brings the contact-wheel 61 opposite the base of the conical portion 0 of the bobbin-receiver C to adapt it to contact with the first layers of yarn deposited thereon whereby, during the winding, the rotation of the contact-wheel will act to progressively advance the layers of winding outwardly along the bobbin.

With the parts of the machine set in the position as above described the roll 58 of the thread-guide 25 will assume a position just clear of the outer circumference of the inclined portion 0' of the bobbin-carrier C as indicated by full lines in Fig. 3. The machine is started to operate through the shifting of a clutch or other instrumentalities, not herein shown, which are controlled through the manipulation of a starting-lever or handle 95 illustrated in Figs. 1 and 2 of the drawings. 'As power is applied to the machine in this manner the winding-spindle 3 is driven to rotate the bobbin-receiver C, and the cam 7 is rotated therefrom to reciprocate the rod 18 in the guideway 17 of the traverseframe 10. The rod 18 imparts reciprocation to the traverse-bar 24 through the medium of the arm 23 connecting these-parts. As the traverse-bar 24 is reciprocated the threadguide 25 carried thereby is traversed back and forth lon itudinally of the windingspindle 3 with an extent of traverse defined by the throw of the cam 7 which is in proportion to the length of the chase to be wound on the tapered butt 0 of the bobbin-carrier C. Initially the thread-guide 25 will be traversed between the base end of the conical butt 0 and the point where its smaller end joins the cylindrical barrel 0. The guide 25 is thus caused to lay the yarn y in helical coils deposited upon the conical surface of the butt 0' of the carrier in the usual manner as practiced in winding bobbins of the present type.

As before stated it is desirable that the delivering point of the guide, that is the point from which the strand feeds to the bobbin, be maintained in close relation with respect to the surface on which the winding is being performed to insure the proper disposition of the coils thereon. In previously'used machines of the present type it has been the practice to allow the guide to contact with the surface of the winding to direct its course u and down the inclined chase of the bobbin, means being usually provided for holding the guide against the bobbin under tension. In the present invention a prime object of the improvement is to prevent the contact of the thread-guide with the surface of the winding while adapting it to follow the incline of the tapered chase on which the winding is being performed.

To provide for this control or regulation of the oscillating movement of the threadguide toward and away from the axis of the winding-spindle the present improved controlling-device functions as follows: With the thread-guide 25 at the rearward end of its throw or traverse the pin 76 on the arm 77 will be positioned at the right-hand end of the cam-slot 75 in the frame 65 as illustrated in Fig. 2 of the drawings. Now, as the traverse-bar 24 is reciprocated from the cam 7 through the medium of the sliding rod 18 it will carry the thread-guide 25 outwardly or to the left as viewed in Fig. 2. As the guide 25 is moved in this direction the pin 76 on the arm 77 which, as before explained, is fixedly attached to the arm 23 extending between the rods 18 and 24, will he slid to the outer end of the cam-slot 75. It will be understood that the in 76 is held by the arm 77 to move in a orizontal course parallel with the axis of the traverse-rod 24. Consequently, as the pin 76 rides along the cam groove 75 it will act to rock the frame 65 upwardly to correspondingly lift the. guiderail 67. This raising of the guide-rail or track 67 of the frame 65 acts through the finger 83 on the thread-guide holder 55 to rock the latter on the axis of the rod 24 whereby to carry the guide-roll 58 inwardly from the position shown by full lines in Fig. 3 to the position indicated by dotted lines in this view. In other words, the rocking of the frame 65 will oscillate the thread-guide 25 to cause the guide-roll 5.8 to follow down the inclined surface of the winding, but the relation between the parts are such as to prevent the roll from contacting with the'winding. As the guide 25 is carried back in the opposite direction the pin 76 slides towards the inner end of the cam-slot 75 to rock the frame 65 downwardly again into first position. During this returnthrow of the guide 25 the frame 65 is caused to oscillate the guide-holder. 55 to move the roll 58 up the incline of the chase while directing its course to prevent it from contacting with the surfaceof the winding. In this manner the oscillating or to and fro motion of the thread-guide is effected synchronously with its longitudinal traversing motion.

As the strand material is deposited on the butt 0 on the bobbin-carrier C it will build up in layers of crossing turns or coils, and eventually the contact-wheel 61 will be engaged by the winding at the inner end of the stroke of the guide 25. During this brief engagement the contact-wheel 61 is rotated to a slightextent to turn the nut 51 which, through its engagement with the screw threads 50 on the rod 24, is caused to feed the thread-guide outwardly on the bar. This action takes place at the end of each rearward stroke of the thread-guide 25 so that the overlying courses of winding are advanced progressively along the receiver C to build the bobbin in the usual manner whereby it is formed with a cylindrical body and of the machine.

a tapered or conical nose-end as indicated by t e dot-and-dash lines in Fig. 2. It will be understood that as the threaduide 25 feeds outwardly on the traverse-r0 24 the bent portion or shoe 84 on the finger 83 slides along the track or rail 67 to maintain the connection between the rockable frame and the thread-guide 25.

After the thread-guide 25 has been fed outwardly on the traverse-bar 24 to a sufficient extent to comfilete the bobbin to the required length, fina y, at the outward traverse of the guide, the leg 52 of the guideholder 55 makes contact with the inclined end of the arm or lever .43 to rock the rod 33. The rockin of the rod 83 releases the detent-latch 36 from the locking member 40 and thus the traverse-frame 10 is unlocked to allow it to swing back under the action of gravity to remove the contact-wheel 61 from further contact with the winding. At this juncture suitable instrumentalities, not herein shown, are brought into action to disconnect the drive of the machine to arrest the winding operation, whereupon the comileted bobbin may bedofi'ed from the man rel 8 and a new tube or receiver placed thereon.

I am aware that it has before been pro osed.

to oscillate the thread-guide of a bo binwinding machine-to direct its course in parallel relation with respect to the inclined chase of the bobbin while holding it from contactin with the surface of the windin .Such a fbrm of construction is shown and described in the pending a plication of J. A. Anderson, Serial No. 281,5 1, filed May 29, 1928, now Patent No. 1,819,695 Aug. 18 1931, but in the machine of this application the oscillation of the thread-guide is effected through the use of a crank or eccentric rotatedfrom a going part In the present invention the use of such a crank-motion or eccentric for oscillating the thread-guide is dispensed with, whereby to simplify the construction of the controlling-device and further to render it more positive anddirect in o ration. In the present invention thelongitudinal traversing movement of the thread-guide is employed to effect and control the actuation of the frame which oscillates the threadaids and through this arrangement a num er of elements are eliminated, the mechanism simplified and rendered more compact, and other advantages secured which will be readily apparent to those skilled inthe art.

In accordance with one form of construction of the invention as herein shown and described the oscillating device for the threadguide is made adjustable to regulate the extent of movement of the thread-guide and to control its range of action for bobbins of different proportions or sizes. This adjusts ing-means is extremely simple in structure, convenient to set and proof against derangement and getting out of order. The

of, a winding-spindle,

mechanism of the whole device, in fact, is reduced to the utmost simplicity while being im roved in efiiciency of operation.

t is further to be observed that the camtrack on the rockable frame and its follower actuated from the reciprocating motion of the thread-guide are susceptible of a change in their re ation or, in other words, a reversal of the parts without affecting their method of operation for the purpose explained.

While I have herein described and illustrated the improvement as applied to use with a certain type of winding machine, and as embodied in a referred form of construction, it is to be un erstood that various modifications may, be made to ada t the device to other forms of winding mac ines, and also in the structure and arrangement of its parts, without departin from the spirit or sco e of the invention. herefore, without limiting myself in this respect, I claim:

1. In a windin machine for winding a bobbin having t e yarn laid ininclined chases, the combination of means for rotating the bobbin, guiding-means for traversin strand material to deposit it on the inclineil chase of the bobbin, means for advancing the guiding-means a ong the axis of the bobbin, and an oscillating-member actuated from the relative movement between the bobbin and the guiding-means to rock the guiding-means to maintain the latter in ad acent relation to the inclined surface on which the winding is performed without contact therewith.

In a winding machine, the combination of a winding-spindle, a thread-guide for guiding strand material to wind a bobbin on the s indle, means for effecting a relative 1ongitu inal traverse between thewindingspindle and threadide, means for causing a relative advance 0 the thread-guide longirogressively tudinally of the winding-spindle, and an oscillating-member actuated from the traversing m otipn to rock the threaduide to maintam it in proximity with t e surface on which the winding is performed while preventing it from contacting therewith.
