METHOD OF PREPARING WOUND PACKAGES FROM SKEINS.

Application filed June 26, 1922. SerialNo. 570,918.

To all whom it may concern;

Be it known that I, WILLIAM G. HANNAH, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Methods of Preparing Wound Packages from Skeins, of which the following is a specification.

According to this invention, having a skeinv which has been wound so that the component convolutions lie one after another side by side in the regular way but each convolution crosses and recrosses each of its next adjoining neighbors an odd number of times, so that the skein has an odd number of what may be termed sheds and crosses alternating therewith, I first place in the several sheds attenuated flexible inserts, as cords, and then fit the skein on a suitable distending support, as a swift, with the in serts' still therein, and then unwind the skein convolution after convolution in the forming of a cop or other wound package which is to be made up from the yarn. Important feature of my invention are the introduction of the inserts in the sheds of such a skein as I have indicated and finally the leaving of the inserts in the sheds during the unwinding of the skein. For my invention contemplates the handling of certain yarns which it is particularly diflicult to control, like artificial silk, or also like crepe or other yarns having a high twist in only one direction and consequently having considerable life, or a tendency to untwist, so that on a swiftthe convolutions thereof tend to. work about and so overlap or intertwist with each other. In the preferred performance ofmy invention, in addition to introducing the inserts and leaving them in the sheds during unwinding of the skeins, I place the latter on the mentioned support, as a swift, so that its crosses register with the cross-arms of suchsupport; this prevents any possibility of the portions of the yarn between the crosses being accidently over-lapped in fitting the skein to such su port. I also fasten each insert to one si e of the support, whereby it can be pulled from time to time in rearranging the convolutions without disturbing those at the side of the skein adjoining the point of fastening the insert.

Inthe drawing, fi gig.v 1 shows a skein wound as above speci- Fig. 2 is a fragmentary view of the skein on a larger scale, with the inserts therein;

Fig, 3 is a fragmentary view of the skein on a swift (shown partly in section), with the inserts therein; and

Fig; 4 is aside elevation of'what appears in Fig, 3.

The yarn is first wound to form a skein as shown in Fig. 1. For this purpose let a and I) represent set of pegs or other supports arranged substantially concentrically, there being an odd number of' pegs in each set and those in one set substantially in radial registry with those in the other. The yarn A is so wound as to pass outward of a peg in the set I) and then inward of the nextpe in that set, and so on alternately con vo ution after convolution, resting on the pegs b which it outwardly passes and on the pegs a where it inwardly passes pegs b'. The result of this will be that there will be formed in the skein sheds c with alternating crosses d. This arrangement, if maintained, obviously keeps the var'iousconvolutions distinct to the end that supposing the yarn to be a high-twisted yarn which cannot undergo dyeing without a tendency to snarl badly, if cords or other inserts be passed through the sheds the skein can thereupon be rearranged or recorded by simply distending it, said inserts acting to maintain the crosses. In the average size skein it is best to provide about nine crosses.

*When the skein has been thus formed I thereupon introduce through its sheds, as shown in Fig. 2, cords or other inserts e; each of these is passed through one shed and then back through the next adjoining shed and may thereupon have its ends tied together to form an endless band to retain it in position. Theskein is then dyedor otherwise treated, but in any case so long as the inserts remain in place the crosses will, remain and so when the skein is distended and properly laid out so that all the inserts are straightened the several convolutions must of necessity take the same relative positions which they assumed in the forming of the skein.

' Having prepared skein in this way it is subjected to unwinding in the following way: In Figs. 3 and 4 I show an ordinary swift f on whose skein-supports g, arranged as usual substantially parallel with and around the axis of the swift, the skein is placed and by which it is held distended under a certain amount of tension. When this is done there should be certainty that all the convolutions lie side by side in their regular order becausethe yarn bein hightwisted and dyed it is exceedingly lively and its convolutions have a tendency in placing the skein on the swift to overlap and in tertwist, the presence of which conditions will lead to breakage and necessitate frequent stopping of the unwinding operation that is to ensue. And so the attendant upon laying the convolutions as flat as possible on the supports 9 then loops each band 6 over one of the spokes f in each pair, having first preferably formed a hitch e in the band so as to embrace the other spoke, the band being held taut by the two spokes. In consequence, each yarn convolution is compelled to take its proper position, of course with some assistance on the part of the attendant by working the skein, which the swift holds fairly taut, with his hands.

The several bands are now severed at a point remote from their hitches 6 so that theunwinding can proceed. During the unwinding, which is effected in the usual way, the swift rotating in suitable bearings under the pull of the yarn as it is wound up into a cop or other wound package, the various inserts are left extending through the sheds, their severed free ends hanging down and free so that as the yarn leaves the skein-supports 9 it wipes them out of the way. If there is any tendency for the convolutions during the unwinding to work over or twist around each other the attendant can always rearrange them by pulling on the free ends of the inserts which, being fastened to the swift at the opposite side, do not at that side of the skein disarrange the convolutions.

I may remark that whereas the inserts are sufficiently flexible so as not to interfere with the unwinding of the fine yarn they are considerably coarser than the yarn, which quality in large measure prevents the convolutions working laterally one way or the other.

In performing my invention, I prefer to arrange the crosses (1 so that they will register with the skein-supports 9, rather than so that they will lie between them. If they lie between the skein-supports it is possible for the attendant in fitting the skein to the swift to leave some of the convolutions overlapping each other and so held by pressure against the skein-supports, which would cause breakage when the unwinding as to those convolutions took place. For this purpose the swift should be so constructed that its skein-supports are spaced from each other distances equal tothe spaces between the crosses d of the skein.

l leretofore it has been regarded as impossible to manufacture fabrics from already dyed crepe or other high-twisted silk yarns having a high twist in only one direction, because such yarns are so completely intractable, due to their life, and consequently tend to roll or work around each other and if they do not become intertwisted at least become overlapped on the swift. By establishing the crosses in the skein when forming it and then maintaining such crosses during the unwinding of the skein I have in practice entirely overcome this difficulty, so that by my invention it is now possible to produce woven fabrics formed of such yarns already dyed, and this of course makes it possible to weave fabrics of such yarns dyed in different colors, which was heretofore unknown.

By my invention it is also possible to overcome the greater part of the difliculty and annoyance which attends the handling of artificial silk in the process of unwinding it from the skein due to its inherent inertness and tendency to lie heavy when in mass and for the strands thereof to catch on or adhere to each other, so that if my method is followed an attendant can serve many more winding units (unwinding from swifts and winding into cops, etc.) than heretofore.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. The hereindescribed method of preparing a wound package of yarn which consists in first forming a skein of the yarn in which each convolution thereof crosses and recrosses the adjoining neighboring convolutions a given odd number plurality of times, then introducing through the corresponding sheds formed between the crosses flexible attenuated inserts, then placing the skein on a swift adapted to hold the skein distended and attaching each insert to the swiftat one side of the skein and then drawing the inserts taut so as to position the convolutions side by side from end to end of the yarn, and then. with the skein distended and the inserts still positioned in the skein sheds, forming the wound package while leaving the swift free to rotate. 7

2. The hereindescribed method of preparing a wound package of yarn which consists in first forming a skein of the yarn in which each convolution thereof crosses and recrosses the adjoining neighboring convolutions a given odd number plurality of times, then introducing through the corresponding sheds formed between the crosses flexible atthe yarn, and then, with the skein distended tenuated inserts, then placing the skein on a and the inserts still positioned in the skein swift having spaced skein supports adapted sheds, forming the wound package while 10 to hold the skein distended and so that the leaving the swift free to rotate.

5 crosses register with said supports and In testimony whereof I aflix my signature.
