' more particularly to means for adapting a machine of this type embodying a rotary traverseroll for winding packages of different lengths or for simultaneously winding a plurality of packages of less length than the'full traverse of the roll.

cated having means for reversing the direction of traverse .of the yarn intermediate the ends 0 I the traverse-roll.

Another object of the. invention is to provide a winding machine of the type indicated in which a single traverse-roll is adapted to simultaneously'traverse multiple yarns to wind a plurality of packages.

Another object of the invention is to provide a winding machine of the type indicated having adjustable means for reversing the direction of traverse of the yarn in either direction at any of the plurality of crossings of the oppositely extending helical yarn paths on the traverse-roll by which the yarn is guided.

Still another object of the invention is to provide in a winding machine adjustable means for reversing the direction of traverse of the yarn which iswsimple in structure and arrangement, efllcient and positive in performing its intended function, and. adapted to be applied to standard types of winding machlnes without alteration in the structure thereof.

Further objects of the invention are set forth in the following specification which describes a preferred form of construction of the device, by way'of example, as illustrated by the accompanying drawings.

In the. drawings:

Fig.3 is a vi and the ends of the traverseew similar to Fig. 2 showing a modified arrangement of ,.the device with plural ges from a single traverse-roll;

traverse-roll.

, Fig. 4 is a view similar to Figs. 2 and 3 showing another modified arrangement of the traverse-reversing means for simultaneously winding three separate packages.

Winding machines of the described in the Reece patent,'referred to above, have gone into extensive use because of the .increased speed at which the yarn can be wound and the facility with which the machine may be operated. In machines of this type a rotary roll having continuous or interrupted grooves, ribs or other like helical guiding means on its periphery continuously traverses the yarn back and forth on the package in oppositely directed helical paths with the direction of traverse reversed at either end of the roll. Each roll is thus adapted to wind a single package of predetermined length.

The present invention relates generally to a stop or abutment mounted opposite the traverseroll, and preferably adjustable longitudinally with respect thereto, to adapt it to cooperate with the helical guiding means of the roll to control the extent of traverse of the yarn thereby. The yarn engages the stop to reverse its direction of traverse intermediate the ends of the Either one stop may be employed to wind a single package of predetermined length less than that of the traverse-roll; or a plurality of stops may be provided for winding several packages from a plurality of supplies. The stops are preferably so constructed and arranged as to permit them to he slid along their fixed support to an operative position and fastened in the double gang type comprising a plurality of d winding units arranged in series along the opposite sides of a horizontal frame or bed 2 supported at its opposite ends by suitable legs, not herein shown. Spaced along the top of the bed I are a series of uprights l which mount bearings 5 for the driving shafts and other parts of the winding mechanism, two opposite units being located between each pair of brackets. but only one unit being herein shown. 1 1

The winding mechanism of eachunit com prises two principal elementa namely, the windingvmandrel or spindle 9 on which the yarn- 1 receiver or cop-tube C is rotatably supported; and .the' roll H for rotating the yarn-receiver and in which is embodied the means for traversing the yarn back and forth axially of the packtype illustrated and be understood, however, that the present inventlon is adapted for use with other forms of traversing rolls incorporating a similar principal of operation and having either interrupted grooves or projecting ribs which direct the yarn in its helical path; or with machines wherein the package is driven by contact with a drive-roll and the yarn traversed by a separate traverseroll; or with machines having any other suitable arrangement of the winding elements.

The term traverse-roll" as hereinafter used in the specification and claims is thus intended to include any type of roll or drum for traversing the yarn back and forth on the package, whether employed as a separate element or constituting the drive-roll as herein illustrated.

In the form of construction shown'in the present drawings the roll H is carried on and rotated by a horizontal shaft ll journaled in the bearings 5 onthe uprights 4; the shaft it being extended throughout the whole: length of the gang machine to carry a plurality of rolls for any desired number of winding units. It wili be understood that in the preferred form or" the machine a second parallel shaft, not herein shown, is journaled in bearings in the uprights 4 at the opposite side of the machine and carries another series of rolls.

The present machine is shown as adapted for winding packages oi cylindrical form with the yarn built up on a suitable axial core or receiver, a paper or fiber cop-tube C for this purpose being illustrated in the drawings as mounted to rotate on the winding-spindle or mandrel 8. In other instances, however, the package may take the form of a truncated cone and in such case the traverse-roll may be correspondingly shaped. A suitable cop-holder i0, herein shown as comprising a cylindrical sleeve, is rotatably mounted on the spindle 9, being provided with any usual means for gripping the cop-tube C thereto. In other instances the holder may be of tapered form to adapt it to receive conical tubes.

The winding-spindle 9 is swiveled at the forward end of a weighted arm l6 which is pivotally supported at its rearward end on a horizontal rod IT to adapt the surface of the yarn-receiver C, and the periphery of the package P, to be held in contact with the periphery oi the roll As the yarn is built up on the cop-tube C it forces the latter upwardly with the arm swinging on its pivot I! in the manner common to machines of the present type. Although not herein shown in detail, a suitable stepping mechanism is employed with each unit of the machine to automatically arrest the winding operation by raising the package away from the roll The stopping mechanism is controlled by a pivoted wire lever l8 held in inoperative position by the yarn being wound.

A tension-device I3 mounted on a bracket 20 is located intermediate the ends of the traverseroll II and positioned at a distance outwardly and downwardly therefrom. The tension-device I9 is preferably of the self-threading type comprising a pair of rotatable tension-disks 2|. Wire threading balls 22 and 23 are so shaped that a yarn drawn thereacross will be automatically 1 guided into an eye 24 in the ball 22 and between the tension-disks 2|.

In accordance with the embodiment of the invention illustrated in Figs. 1 and 2 of the drawings, a single stop or abutment is adjustably mounted closely adjacent the traverse-roll II to adapt it to engage the traversing yarn to reverse its direction of traverse at any one of the plurality of crossings of the helical paths through which the strand is guided. The stop 30 may take any suitable form or shape, being herein illustrated as a cylindrical post or pin with a smooth rounded surface for engaging the yarn. The stop 30 may be mounted on any suitable support which may constitute a standard part of the machine or be applied thereto as an attachment. As herein illustrated, the stop 30 is mounted on a horizontally-extending support 3| which is in the form of a rod having its opposite ends held in sheet-metal clamps 33 fastened to the uprights 4 by screws 34. The clamps 33 are bent around to embrace the ends of the rod 3| which are clamped therein by means of bolts 35. The stop 30 has a transverse bore 36 through which the supporting rod 3| extends to mount the stop for adjustment longitudinally oi the traverse-roll II. An axial, threaded bore 3lis also provided in the stop 3|) for receiving a setscrew 38 which is set up against the rod 3| to- 'clamp the stop in adjusted position thereon. By

loosening the set-screw 38 the stop 80 may be moved along the supporting rod 3| to any desired operative position intermediate the ends of the roll ii or to an inoperative position outwardly beyond the ends thereof. One form of the in vention having now been described in detail, its mode of operation will be next explained.

The strand of yarn y is drawn off from a bobbin or other source of supply, not herein shown,

laid across the threading bail 22, the rod 8| and roll II, and its end secured to the cop-tube C. If a package of standard length is to be wound a cop-tube C of a length substantially equal to that of the roll II is applied to the holder H! on the winding-spindle 9 at the end oi. the arm IS. The arm I6 is then lowered into position to place the surface of the cop-tube C against the roll ii. The roll H is rotated continuously and the cop-tube C rotated therefrom to wind the yarn onto its periphery. As the yarn y is drawn across the threading ball 22 it is caused to automatically enter the eye 24 and between the tension-disks 2| to both guide and tension the strand as it leads to the roll As the yarn draws across the rod 3| it is picked up by the groove I! or l3, or such other means as provided on the periphery of the roll H, to traverse it back and forth along the tube C to commence the winding of the package.

To adapt the machine to wind packages of a length shorter than that for which the standard roll is designed, a spindle and cop-tube holder or appropriate length are substituted for the standard spindle and holder. The stop 30 is then adjusted on the supporting rod- 3| to a position slightly in advance of a particular intersection a: or the oppositely directed helical yarn paths on the roll Ii, being spaced from the terminus of the grooves in the roll a distance corresponding to the length of the package to be wound. To accomplish this adjustment the setscrew 38 is loosened to permit the stop 30 to clamp the stop fixedly in place. Preferably, the

angular position of the stop II should be such that the stop will extend outwardly from the rod 3| at right-angles to the direction of feed of the yarn.

With the roll ll rotating in'a counterclockwise direction, as viewed in Fig. 1, the groove II causes the yarn y to be traversed from the righthand end of the roll toward theleft ,until it engages the stop SI as indicated by the dotand-dash lines in "Fig. 2. As a result of this engagement the yarny is restrained from further traverse to the left and the length of yarn extending between the stop and roll II is deflected to the right as it reaches the crossing a: of the grooves l2 and I3, thereby causing it to be diverted into the return groove l2. The yarn y is then traversed toward the right-hand end of the traverse-roll to the position indicated by dash lines in Fig. .2 where its direction is again reversed as it again enters the groove It. The yarn y is thus traversed back and forth throughout a portion. only of the length of the roll I I to build a package P of a length less than that of the roll. Fig. 2 illustrates the machine as adapted for building a package P of approximately two-thirds the length of the roll II; but

it will be understood that packages of several other lengths may be wound with: the type of roll here shownby adjusting the stop 30 to a position slightly in advance of any one ofthe five crossings of the. oppositely directed helical paths formed by the grooves l2 and I3.

If the yarn y breaks or becomes exhausted during the winding of a package, and when a full package P has been completed, the stopping mechanism acts to lift the arm It to move the package away from the roll. the yarn y may then be repaired, or the completed package dofled and the machine prepared for a subsequent winding operation. The stop- 30 is preferably made of such length that when the arm i6 is lifted to its uppermost position the yarn y will still be in engagement with the stop as indicated by dash lines in Fig. 1.

In the embodiment of the invention illustrated in Fig. 3 of the drawings, a pair of stops 30 are mounted on the supporting rod '3! to adapt them to function for reversing the direction of traverse of a plurality of yarn strands y and y intermediate the ends of the roll II to simultaneously wind two packages P' and 1. As herein shown the stops it are positioned at thelongitudinal centerof the roll and inabutting relationship. Two yarn strands 1/ and 3 are fed from independent-sources to lead across the rod II on opposite sides of the pair of stops 30 with their ends attached either to .a single cop-tube or a pair of tubes C, injthe usual manner. As the roll II is rotated the septratestrands 1 and 14* feed through the traversing grooves and i3 at-the opposite ends. of the roll, as indicated by dash lines in Fig. 3, and are caused to be traversed toward'the center of the roll until they engage the stops 30.. As explained with respect to the first form of construction illustrated in Figs. 1 and 2,-the lengths of yarn between the stops II and the roll; H are deflected as'they approach the center crossing z of the oppositely understood that with the last described arrange- The break in ment the stops 30 may be adjusted to a position in conjunction with any of the other crossings in Fig. 4 of the drawings, two pairs of stops 0 are mounted on the supporting rod II to adapt the machine to wind three separate packages in spaced relationship on the spindle 0; one package being wound at the center of the roll H between the pairs of stops and the other two at the opposite ends of the roll. In this form of construction the grooves l2 and I3 on the roll II have a greater number of crossings and the stops 30 of one pair are adjusted to a PO? sition opposite the crossings :c" and 2: toward the left-hand end of the roll while those of the opposite pair are positioned opposite the crossings x and :1." toward the right-hand end of the roll. sources, arefed across the rod 3|. through the grooves l2 and I! at the opposite ends of the roll u, and a third strand 11 1s fed between the 25 inner stops of the opposite pairs. Rotation of the roll ll causes the yarn strandsy'. and 11' to be traversed from the outer ends of the roll ll toward its center until they engage the outermost steps 30 of each pair and their direction of traverse is then reversed as explained with respect to Fig. 3. The yarn strand 1! is traversed in the groove it from the cross ng 23 toward the .crossing- :1: until it engages t e inner stop 30 of the right-hand pair which causes it to be diverted into the groove ll to reverse its direction of traverse. The yarn 1/ is then traversed by the groove II in the\ opposite direction, or toward the left, until it engages the inner stop 30 of the left-hand pairt whichgin turn causes it to be diverted to the pposite groove 12. It

.will also be'understood hat packages of still dlflerent dimensions may be wound on the machine by adjusting the stops to other positions.

It will be observed from the i'oregoing'that the present invention provides a novel and simple arrangement of means'ior reversing the direction of traverse of the yarn intermediate. the ends Yarn strands 1! and 11" from independent of a rotary traverse-roll to adapt the machine ingfrom the spirit or scope of, the invention.
