Patented Nov. 11, 1952 Ernest J. Griset, Jr., Asheville, N. 0., assignor to American Enka Corporation, Enka,-N. 0., a corporation of Delaware Application'March 3, ssa'seriai No. 274,532

after all of the loops are in position, rotation of the-reel is initiated to cause it to wind on itself a plurality of skeins. Solong as the yarns or threads which are to be prepared in skein form are drawn from a static source such as a 'j:

package or cake, the threading-in arrangement described above is quite satisfactory. On the other-hand, when the threads are being continuously delivered in runningjform as by a continuous spinning machine, the threading-in 'of a skein winder of the type which winds a plurality of skeins'on a single reel presents difficulties. Theproblems arise out of the necessity for taking care of the'thread running to theloops'already-tied-on the reel while the remainder arev being tied.

.: It is -.-thereforeian objector this invention .to

provide fortheconvenient and easy threadingein o'fa skein winding reelwith a plurality of runningi ends while minimizing waste of yarn and operatortime:

Other objects and advantages-of this invention will be apparent upon consideration of the fol-' lowing detailed description of .an embodiment thereof inconjunction with the .annexed draw-- ings whereim.

Figure 1 is a-view in elevation of a skein wind- -ing reel incorporating the improvements of. the

present. invention;

Figure 2 is a view in the line 2-2 of Figure 1; and

Figure 3 is a view similar to Figure 2 but showing the reel in a difiicult angular position to illustrate a different stage in the threading-in operation.

Referring now in greater detail to the drawcross section taken on stood upon concurrent reference first to Figures ings, the numeral l0 designates a skein winding f reel of the type constructed to accommodate and wind six skeins simultaneously. The reel I0 is comprised of six spiders ll, l2, l3, l4, l5 and; I6, axially equally spaced along a shaft ll. The.

shaft I1 is iournaled in bearings l8 and i9 and is connected to be rotated by conventional mechanism, not shown.

Each spider is provided with six spokes radiating from a hub and, since the spider I3 is"'- 2 4 typical of all of them both as to configuration and angular position on the shaft Il, only that spider is shown in end view.

The outer ends of the spokes of the spiders I l to l6, inclusive, are connected to rods 20, 2|, 22, 23, 24 and 25, which define with the spiders a cage-like structure. Each spider has associated with it a thread guide to lead the thread from a source, not shown, to the approximate plane of the approximate spiden, These thread guides are identified in Figure 1 by numerals Ilatolfia, inclusive.

It will be understood that the skein winder thus far described isentirely conventional. As a part of the present invention each spider .is

providedwith a stud l l b to 5b, inclusive, projecting from its side parallel to the shaft H, and m a line between the tip of a spoke and the center line of the reel. V

Associated with two of the spokes and the appropriate guide for each spider, there is a suction device which is capable of taking up a running yarn by exerting a pull thereon of constant.

magnitude sufficient to prevent slack but not enough to cause thread breakage. These devices. which are indicated by reference numerals 26 to 3|, inclusive, themselves form no, part of the; present invention being disclosed and described- 1 and 2 and then to Figures 1 and 3. The run ning yarns or threads issuing from sources not shown are led immediately to the appropriate suction device and are then dropped in the appropriate guide. Thus an initialthread path is established between the thread guide and each spider and the suction device for that spider. When all of the threads are running to the appropriate suction device, the operator draws a loop between the thread guide and the suction device and drops the running thread behind the projecting stud. See the broken line path of the thread in Figure 2. When all of the threads are running in accordance with the pattern de picted in broken lines in Figure l, the reel is caused to rotate in a counter-clockwise direction as it is viewed in Figures 2 and 3. The effect of this rotation is apparent in Figure 3 and as soon as suflicient overlapping has occurred to insure anchorage of one end of the thread on the reel, the thread or yarn is cut immediately adjacent the appropriate suction device as indicated at in Figure 3.

From the above description it will be noted that an advantage of this invention resides in the fact that it is entirely unnecessary to wind any sort of loop about the skein-winding reel before the rotation of that reel is initiated. In other words, in threading-in, a condition is established which may be described as a condition precedent to :the automatic formation of a loop, that condition precedent being depleted in broken lines in Figure 2. The condition is a stable one and affords ample time for the operator to get all of the threads so running before initiating rotation of the reel, and once rotation of 'the reel is commenced, all of the loops are wound at once and cutting of the threads-running'to thmsuetion device can be quickly and easily accom- .plish'ed.
