., assignors to Celanese Corporation a corporation of Delaware Application March 17, 1945, Serial No. 583,222 13 Claims. (01. 57-75) This invention relates apparatus for twisting and winding yarns to form yarn packages, and relates more particularly to twisting and winding apparatus for the production of yarn packages having a magazine wrap or transfer tail.

A magazine wrap or transfer tail, as commonly understood in the art, is a portion of the inner end of the first yarn wound on the yarn support and so disposed as to be positively secured during the winding of the remainder of the yarn package yet readily available for tying directly to the outer end of the The purpose of providing a magazine wrap or transfer tail on a yarn package is to enable an uninterrupted flow of yarn to be maintained from a depleted yarn package to a full yarn package adjacent thereto, as in a creel or other yarn package holder upon which the yarn packages are supported.

An object of this invention is to provide an improved apparatus for Winding yarn on to a yarn is provided.

Another object of this invention is the provision of relatively simple and efflcient means wrap or transfer tail yarn package.

Other objects of this invention will appear from the following detailed description and the accompanying drawing;

In the accompanying drawing, wherein a preferred embodiment of our invention is shown, the figure is a side elevation view, partly in section, of our novel apparatus for the application of a magazine wrap or transfer tall at the base of a bobbin.

Referring now to the drawing, a yarn 2 passing through a yarn guide 3 and coming from any suitable source of supply such as a metier or spinning cabinet (not shown) passes downward and is threaded through a traveler 4 mounted on to twisting and winding yarn on another yarn package.

' a spinning ring 5 set in a ring holder 6, the latter yarn support is rowith a pair by beam l5 which is being mounted on a plate 1. Plate 1 is integral of dependent, triangularly-shaped bracing members 8, onlyone of which is shown in the figure,.which bracing members are attached, for added rigidity, to a fiat bracing section 9 lying between said bracing members ,3. Plate 1 extends beyond members 8 to form a lip III, the latterbeing provided with suitable holes at H adapted to receive a pair of'symmetrically disposed guide rods or shafts l2, only one being shown in the drawing for the sake of clarity. Shaft I 2 is attached, as by bolts 13 and M, to a vertically reciprocating beam l5 forming part of and extending across the twisting andwinding' ber 8, bracing section 9 and member l8 dependingtherefrom is caused to be reciprocated as a unit vertically reciprocated by suitable means (not shown). Plate 1, and particularly lip l0 thereof, though physically unattached to beam i5, is maintained in contact therewith through the medium of a tensioned. spring l9. One end of spring l9 passes around a stud ,20 set in bushing l1 and the other end is attached to a bracket 2| fixed to the lower surface of beam IS-as by a screw 22. The force exerted by tensionedspring I!) is sufiiclent to maintain lip l0 and beam It in a constant spring? loaded surface contact and to prevent any play therebetween.

The bobbin upon which the yarn is wound to form the desired yarn package, which bobbin is indicated by reference numeral 23, is supported on a spindle 24 rotated at high speed by suitable driving means (not shown) in the normal manner well-understood in the art. The desired type of wind on the bobbin 23 is produced bined reciprocating vertical traverse, or chaser motion, of beam l 5 with that of spindle 24, which is provided with a reciprocating vertical, or builder movement in timed relation to that of beam I5 I The builder motion of spindle 24 is .achieved through the action of a pinion 25 keyed to a shaft 26 and meshing with a rack 21 mounted on the bolster 28 of the spindle assembly. Shaft 26 is provided with driving means (not shown) adapted to be reversed in timed'relation to the by the comtraverse of beam i5, producing a yarn package of wind possesses particularly valuable characteristics. The entire spindle assembly is supported -on a heavy, braced, cross-piece 29. A more detailed description of the manner in which the builder motion is superimposed upon the chaser motion to produce the unusually advantageous cover wind on the bobbin, is given in U. 5. Patent No. 2,357,406.

To provide the desired magazine wrap or transfer tail during application of the cover wind, the operator halts the spindle by depressing brake handle 30 bringing brake shoe 3| in contact with the spindle base 32, dotls the full package, replaces it with an empty bobbin in the usual manner and then throws on the yarn to start the wind. As soon as the yarn 2 begins to wind on to bobbin 2} and the traverse of the beam I5 is on the downward motion, platev I, is depressed by hand against the tension of spring .19 so that bushings I6 and I! slide in a downward direction along shaft l2. Plate 1 is forced downward until it comes in contact with adjustable stop 33 thus moving lip Ill out of contact with beam IS. The downward movement of plate I carries the ring and traveler to a position just below the normal traverse of the yarn 2 as provided by the combined reciprocating vertical builder motion of the spindle 24 and the chaser motion of the traversing beam i5. This movement of plate I places the latter in position indicated by reference numeral 1' and brings the ring 5 to position indicated by reference numeral 5'. With ring 5 in position 5' the yarn 2 winds onand forms a magazine wrap or transfer tail 3 at the base of bobbin 23. As soon as the desired magazine wrap or transfer tail 3 is formed, the operator releases plate I and the action of spring I! draws plate 1 upward from position 1' so that lip i0 is again in contact with the lower surface of beam is. In

this position yarn 2 then commences to wind on to bobbin 23 in the normaimanner and the combined builder and chaser motion of the spindle 24' and beam II causes the yarn to build up in the form of the desired yarn package.

The magazine wrap or transfer tall 34 thus placed on the yarn support is well separated from the main body of the yarn and is readily available as a transfer tail.

While our invention has been more particularly described in connection with a twisting and winding apparatus in which both the ring rail and spindle are provided with a reciprocating vertical movement or traverse so as to produce a cover wind in the yarn package formed, it is to be understood that our novel apparatus is equally applicable to a twisting and winding device in which only the ring rail reciprocates to build up the yarn package.

It is to be understood that the foregoing detailed description is given merely by way of iilustration and that many variations may be made therein without departing from the spirit of our invention.
