of another package in the conventional manner to accomplish continuous transfer from the first package to the next and so on indefinitely.

It is an object of the present invention to provide a tail winding arrangement of such character that the yarn during winding into the tail passes about a guiding surface having the minimum possible difference in angle from that of the yarn when it is being wound into the main package. A further object is to avoid irregularity in the tension exerted on the yarn during the tail-winding by providing a tail-winding system in which the yarn is not under the influence of the traverse guide during tail-winding but is automatically caught by the traverse guide after release by the tail-winding guide. In this manner, the tension to which the yarn is subjected is not substantially different during winding of the tail than during winding of the package, and there is little opportunity for the fabrics made from such packages to show differences at the regions ,formed of the tails, in appearance, handle, dyeing characteristics, and the like, when artificial yarns such as rayon, vinyl resins, nylon and the like, which are peculiarly sensitive to variations in tension, are used for producing the fabric.

Another object is to provide a tail-winding system which is simple to lace or thread up, and which requires no special skill to operate.

Other objects and advantages will be apparent from the drawing and the description thereof hereinafter.

In the drawing, illustrative of preferred embodiments of the invention- Figure 1 is a side elevation of one embodiment of the invention;

Figure 2 is a perspective view from above of the embodiment of Figure 1; and

Figure 3 is a side elevation of a modification.

As shown in Figures 1 and 2, the tail-winding arrangement of the present invention is applied to a cone winding machine having a winding head of conventional form for supporting the winding core 2 for rotation in response to the driven spindle 3, a suitable clutch and hand lever (not shown) being provided to start 'or stop this rotation. A supporting frame 4 is provided 10 Claims. (Cl. 242-18) to carry the traverse guide 5 and the bracket 6 for maintaining the guideway I for the traverse guide 5 in definite relationship to the frame t. The frame 4 carrying the traverse guide is pivotally mounted on an axis at 8, so that it may be manually swung toward or awayfrom thewinding core 2. The frame is counter-weighted as at 9, so that it normally is held with the guide 5 bearing with a light pressure against the core 2 or the winding thereon. As the package builds up, the frame 4 is swung outwardly in response thereto. vided to reciprocate the guide 5 back and forth longitudinally of the winding head the entire length of the package, and this mechanism may be ofthe conventional type such as is shown in the U. S. Letters Patent No. 2,193,117, March 12, 1940, and is controlled by the same hand lever referred to above which starts and stops rotation of the spindle 3, as is the conventional practice. 1 The thread guide 5 has its thread-guiding notch 10 opening into the lower edge of the guide and" the adjacent notch defining surfaces II are smoothly curved back from the face of the guide opposite to the winding core 2 into gently sweeping wings or projections I 2. V

The thread or yarn proceeds from its source (not shown) through any suitable tension-controlling device l3 and past a suitable fixed guide l4 and then to the winding core through a path lying between the traverse guide 5 and the pivotal axis 8 of the frame 4. During winding of the package, the guide 5 takes the dotted line position against the core 2 and the thread or yarn is controlled by the guiding notch I 0 through which it passes, during such winding.

A tail-winding guide I5 is mounted by a I threaded connection to the frame 4 and a lock nut l6 permits adjustment of the guide to any suitable angle and extent ofprotrusion from the frame 4 so that the tail may be wound at any predetermined distance from the cone base.

' As shown inFlgures 1 and 2, the guide I 5 may simply be a bent wire having a thread-guiding projection approximately parallel to the-plane of the tail winding and extending in suchga man--v ner that the thread entrance of the tail/guide faces that of the traverse guide 5. However; it should be noted that the guide l5 lies {beyond the traverse strokes of the guide 5. This paras-1; lelism is not essential since the extreme tipoi' the guide l5 may extend either inwardly or out; wardly a substantial distance from suchapa e containing the bend in the tail guide, as be Suitable traverse mechanism is proapparent from the description of the tail winding operation.

When starting the winding of a new package, the operator swings the frame 4 to any position. such as that shown in Figures 1 and 2, away from the winding core, unless it is already in such a position, in which case this step may be omitted. He then laces the thread through the tension device l3 over the guide I4, back of the tail guide l5, and secures it to the winding core.

The leading end of the thread may be secured to a notch in the edge of the winding core, or a short length of its leading end may be pinched between the winding head and winding core by placing the end of the thread over the winding head before the core is placed thereon. Then the rotation of the winding head is started, preferably slowly, and when suflicient tail is wound the frame l is swung toward the winding core 2. During this swinging motion, the tip of the tail guide passes through a point It at which the yarn is released therefrom and gradually winds outwardly on the core 2. During all this time, the guide 5 has been traversing, and after the yarn is released, the guide soon comes into contact with it on its inside projection l2, regard-- less of which direction the guide 5 may be traveling at the given instant of contact. Quickly after such contact has been made, the yarn is forced over the shoulder l I and into the notch l0. Winding of the package then proceeds in regular fashion with the guide 5 in contact with the winding. Y

As shown in Figure 3, the tail guide l5 may be adjusted to give a modified relative position of the parts at the time of its release of the yarn at R. This may simply be accomplished by loosening the lock nut l5 and swinging guide I5 to another angular relationship before again tightening the nut. Also, the guide l5 may be replaced by another having a longer thread-guiding arm projecting into closer proximity to the traverse line of the open end of the notch l0, thereby delaying release until the guide 5 is much closer to the winding core 2.

By reference to the drawing and the description thereof it will be seen that irregularity in the tension of the yarn during winding of the tail is avoided entirely since the yarn is not under the influence of the motion of the traverse guide 5 during suchwinding. In addition, there is little or no difference in the tensions exerted on the yarns during the winding of the tail and of the package, since the angle which the yarn takes about the guide is approximately the same as that which it takes as it passes through the guiding notch ID of the guide 5, regardless of the position of the guide 5 in its stroke. The lacing up of the winding machine is extremely simple and relatively inexpensive parts are all that are needed to provide the tail winding arrangement.

It is to be understood that changes and variations may be made fromthe description here n without departing from the spirit and scope of the invention as defined by the appended claims.
