This invention relates to a yarn winding device I and more particularly to a novel yarn guide for use on a yarn cone packaging machine.

In devices that draw yarn from a source o1' supply and, with or without inserting twist therein, wind the yarn into a cone there is usually provided a guide for directing the yarn onto the cone. This guide reciprocates back and forth across the package and also bears against the windings on the package, it being adapted to be mechanism are not shown as the present invention is operable with all conventional types of cone'winding machines. Operating in timed recarried on a pivoted arm so that when the package reaches a predetermined size the arm actu invention had a tendency to scuff up the yarn on the package and also to'create such friction that extremely hard packages were formed which were difcult to unwind on knitting and like machines.

It is accordingly an object of this invention to construct a guide for cone winding machines that reduces to a minimum the tension'eXerted on the yarn and the pressure applied to the package during winding by the guide.

Another object of this invention is the provision of a yarn guide in which Wear at the contact points is substantially reduced.

A further object of this invention is the provision of a yarn guide in which yarn breakage is substantially eliminated and which enables softer packages to be produced, due to the reduction in guide wear and yarn tension.

Other objects of this invention, together with certain details of construction and combinations of lparts will appear from the following detailed description and claims.

In accordance with my invention I construct, for use in cone winding machines and like winding devices, an anti-friction type of guide comprising a roller guide and roller bail mounted on the pivoted guide arm normally employed on such winding devices.

'In the drawing wherein one embodiment of my invention is shown,

Fig. 1 is an end elevational view of my novel yarn guide structure showing it in relation to the cone of yarn being wound, and

Fig. 2 is a top plan view of the same.

ALike reference numerals indicate like parts throughout both views of the drawing.

Referring to the drawing the reference numeral I indicates the cone of yarn which is beingbuilt into a cone on a core 2 of cardboard or other suitable material. This core 2 is adapted to t on a spindle of a. cone winding machine and to be rotatedthereby, which spindle and its driving lation to the rotation of the yarn package is a guide generally indicated by the reference nu meral 3. The guide 3 comprises a carriage 4 provided with a tongue 5 forming a V-shape groove therewith, which groove is adapted to receive a polished edge or track 6 of a pivoted guide arm I.`

The carriage 4 is caused to reciprocate on the track 6 by means of a rod 8 attached to a projection 9' on the side of the carriage. IThe rod 8 in the standardmachines is operably connected to a cam (not shown) that is 'driven in timed relation to the rotation of the package I.

A roller guide II having each end rounded, as at I2, in order to prevent damage to the yarn of the package is carried by the carriage 4. Roller guide I I, which is recessed at` each end to accommodate a ball bearing I3,'is mounted on a stationary spindle I4 supported by a U-shaped holder I5. A'forked wire guide I6 is attached to the guide holder I5 or, as shown, to the carriage 4 immediately behind the roller guide II for the purpose of preventing the yarn A from leaving 'a V-groove I1 that is formed in the roller guide II. The roller guide II is preferably formed of polished tool steel and `may be of any desired size. For the purpose of building cones from yarn of less than one thousand denier the roller guide should be approximately l/2 inch long s of an inch in diameter with the V-groove Il being about 11s of an inch Wide and of the same depth. As stated, the roller guide may vary in size, and may also be madeof any suitable material. Oper- Y ating in conjunction with the roller guide II is a `and passing through the tensioning device or devices normally employed' on conepackaging machines, is carried over the free running rollerbail I8 through the forked wire guide I6, into the groove I'I of the roller guide I I and on to the takeup package I. The roller bail I8 is frictionally rotated by the yarn A while the roller guide- II is driven by the surface of the rotating package I, with which it is normally in contact, and at approximately the same linear speed. By employing this invention, there is obtained a reduction in the tension on the yarn and the pressure applied to the package during winding, thus packages which are lower in density are produced. Moreover, fewer ends of yarn are broken and a more freely unwinding package is produced by the present device than by devices employed prior 1. A guide for winding yarn onto packages comprising a. roller guide having a guide groove therein for receiving and guiding the yarn being wound onto the package being formed, a forked Wire guide for maintaining the yarn in the groove and a carriage supporting said roller guide and forked wire guide.

2. A guide for Winding yarn onto packages comprising a roller guide having a guide groove therein for receiving and guiding the yarn being wound onto the package being formed, a track, a carriage mounted on said track supporting said roller guide and a roller bail attached -to Said track.

3. A guide for winding yarn onto packages comprising a roller guide having a guide groove therein for receiving and guiding the yarn being wound onto the package being formed, a. forked wire guide for 'maintaining the yarn in the said groove, a carriage for supporting said roller guide and said forked wire guide and a track upon which said carriage is adapted to slide.-
