My invention has to do with a new method of and apparatus for the winding and subsequent treatment of filaments, especially artificial silk laments.

Methods are known whereby the thread is accumulated in narrow spirals to form a ring shaped package. However, the filaments in such a package are wound so loosely that the same becomes very difficult to handle. Moreover, the filaments are likely to become damaged during the unwinding process, as the spirals tend to become tangled and knotted. v

One object of my present invention is to wind the filaments in such a way that they may not 15 become entangled in subsequent treatments.

` Another object of my invention is to so wind the filaments that the same do not become damaged because of shrinkage.

A still further object is to provide an apparatus wherein the package of yarn so formed may be treated.

These and other objects will become more apparent from a study of the following specification, and of the attached drawing in which:

Figure 1 is a plan view of the base of the package;

Figure 2 is a cross sectional View of the spinning arrangement for the manufacture of the package to be wound according to Figure l; and

Figure 3 is a cross sectional view of the package inserted in the treating tank.

Referring now to the drawing, I have shown in Figure 1, the manner in which the filaments are wound into a package according to my present invention. It should be noted that the diameter of the loops of the filaments or threads 1) is larger than the radius of the packages. By such winding the shrinkage .which results from subsequent after treatments is taken care of and the filaments or threads in the interior of the yarn body are flexibly wound although there remains considerable coherence of the filaments in a radial direction. Such result is obtained by winding the thread in the loop form as shown.

5 yarn body is built up axially by means of a cone shaped base upon which the thread is placed in a plurality of layers.

`In Figure 2. I have shown a sectional view of the spinning arrangement in which the threads or filaments are formed into a package in the e manner set forth above. Thel freshly spun threadl or filament 2) is led vertically downward into the funnel shaped upper mouth (3) of the gu'de pipe (4). Treating liquid is also introduced into the funnel portion of the guide and assists in moving the thread downwardly through the guide to the container.

The thread guide funnel 3 is supported by the shaft 6 through the medium of a bracket 14- which is secured to the shaft 6 and rotates with it. The bracket 14 has arms 15 bored to receive the shaft 16 of the funnel 3. Through the rotation of the shaft 6 the gear 5a rolls around the gear 5 in a planetary motion thereby causing the stem 4 of the funnel 3 to carry out a cycloldic 75 motion.

The shaft 6 extends through a hollow shaft 6a. which is supported by a bearing 1'7 thereby supporting the planetary gear arrangement along with the funnel 3. 50

In the arrangement shown the hollow shaft 6a and gear 5 are stationary and it will be readily apparent how the cycloid movement takes place.

It will also be obvious that it would be possible to rotate thehollow shaft 6a in the opposite di- 85 rectionl to the shaft 6 and thereby gain a closer w'nding of the threads.

When it is necessary to lift the yarn package for wet-treatment according to Figure 3 this can readily be done by lifting the funnel and gears asY a unit any suitable release coupling for the shafts 6 and 6a being used. It is advisable to move the upper end of the guide pipe in a small path so that` the thread will be maintained in the same direction-at all times. The thread (2) emerging from the lower end of the guide pipe is thus placed in a plurality of loops (see Figure 1) into a collecting container (7). The container (7) is annularly formed and the bottom surface m0 thereof-is cone shaped merging into a hollow perforated core (9). The casing (7') constitutlng the side walls of the container is removably secured to the conical bottom. Because of the conical shape of the bottom portion of the container the thread will be placed in cone shaped layers thus obtaining a yarn body which is more securely packed in the axial direction thereof so that the thread can be unwound more easily without knotting or entangling the thread.

The package thus formed does not require a special support.

Because of the peculiar formation of the wound package the necessary and usual treatments may be performed to greater advantage. To avoid entanglement of the thread layers, the wound package is left in the container ('7), the removable casing portion (7') thereof is removed, and the conical portion and core with the yarn body is then placed in the treating container (l0). As will be noted this treating container is provided on its bottom with a flanged portion or ring (11) so shaped as to receive the curved bottom portion of the container (7). To hold the top layers of the yarn body in position, I have provided a ring shaped rubber disc (12) which ts snugly against the top conical edge of the yarn package. A plug (16) is then inserted in the aperture (15) in order that the treating liquids may be drawn through the Walls of the yarn body. Any desired means of Washing or treating the yarn body may be used. I have sh-own in this instance the use of a suitable vacuum system to suck the treating liquidcontained inthe tank from the outside to the inside of the yarn body and thence through the perforations formed in the core. liquids will be sucked through the yarn body at The liquids will necessarily take this path in their passage through the yarn body due both to the shape ofthe conical portion of the container and the rubber disc` and also because of the fact that the layers of thread of the yarn body have been wound in a conical manner. It is to be understood, however, that other methods of treatment may be used. For eXample,-the liquid may be forced through the pipe (12), instead of being sucked therethrough as described above, through the perforations in the core, and thence from the inside to the outside of the yarn body.

From the above description it will be appreciated that I have provided a new method of winding artificial silk and a newarrangement for accomplishing the method. By forming a yarn body having the layers arranged as indicated in Figure 1, I have avoided the knotting and entangling of the thread during the washing and/or treating steps. Moreover the finished yarn package may be unwound more easily and at the same time the layers will not become entangled while in the package form.

Although I have described one preferred form of my invention, it is obvious that many changes may be made in the mechanical construction of the spinning device without departing from the spirit or scope of the invention. I wish it, therefore, to be understood that my invention is not to be limited except by the scope of the appended claims.
