In the Ntherl ds August 19, 1931 during spinning.

In the artificial silk industry, when use is made of pot spinning frames, there is agreat consumption of power; moreover there is danger of the thread being injured during the further treatment; when use is made of bobbin spinning frames, the inconvenience is that the thread must be twisted afterwards.

My invention has for its object to obviate those drawbacks by simple and economical means.

With this object in view my invention essentially consists in the special arrangements and combinations of parts hereinafter fully described and pointed out in the appended claims.

In the annexed drawing:

Fig. 1 is a side view of a winding, member,"

' illustrating the principle on which my invention is based;

Figs. 2 to 4 are vertical sectional views, showing three modified embodiments of the invention for the spinning of threads of anykind whatever;

Fig. 5 is a view similar to Figs. 2 to 4, illustrating a. further modification adapted to be used more especially for the spinning of artificial silk.

As is well known, in cap and ring spinning frames, the thread forms a so-called balloon produced by the action of centrifugal force on the thread being spun, and this balloon tends todisplace-itself, if not kept in place, towards the guide eye through which the thread normally passes. a

The new-system of spinning has been based on these two considerations. The problem consists in devising means whereby the thread can be wound under a certain tension, at the same time enabling a displacement along the spool in an axial direction of the yarn being wound (traverse motion).

Referring to Fig. 1, which shows by reference I a winding member for the yarn, by reference 2 a. guide eye, and, in dotted lines, by reference 3 the thread forming a so-called balloon l, the problem has been solved by pressing down the balloon to form what I have termed herein a tail 4 by means of a member 5, for instance a cylinder, cone or other body of an appropriate shape having an inside diameter smaller thanthe maximum diameter of the balloon.

When spinning, the friction of the yarn against 5 the cylinder causes it to be wound on the spool, traverse motion being obtained by moving said cylinder or other member up and down, the tail 4' of the balloon (part going from spool to the largest diameter of pressed down balloon) folf lowing this-movement. The necessary tension is derived from the centrifugal force acting on the tail.

In the example shown in Fig. 2, 6 is a rotating bobbin on which a thread for instance of artificial silk is to be wound. I is a cap which sur-' rounds the thread presented to the bobbin and also the portion of the bobbin on which the yarn is to be wound.

Under the action of the rotation of the bobbin and of the resulting centrifugal force, the thread takes the shape of a balloon and is thrown against the inner wall of the cap I, which exerts a braking action on the yarn. The feed proceeding in a continuous manner, the yarn is adapted to be wound on the bobbin, the necessary tension to this end being produced by the centrifugal action consequent to the rotation of the bobbin.

The cap I and the bobbin 6 are mounted so as to be adapted to be displaced relatively to each other in an aixal direction so as to cause the thread to be wound in regular layers, and to render'pcssible the removal of the filled bobbins from their working position and to substitute empty bobbins.

In the form of embodiment shown in Figure 3, the cap I is replacedby a cylindrical member 8 also exerting a braking action on the yarn and guiding it by its lower edge.

The yarn adducted to the cylinder 8 is guided 40 by means ofanordinary thread guide or lappet 9 fixed to the frame of the machine, and the form of the balloon is adapted to be controlled by varying the distance between the said guide 5 and the bobbin or winding element 6.

Preferably, the thread guide is arranged however at a short distance above the said bobbin.

The cylindrical member can also be provided In Fig. 5, l3 designatesa thread guiding member, used more especially for the spinning of artificial silk.

Obviously, my invention is not restricted to the specific construction as described but it must be understood that this construction can be modified in various ways without departing from the principlesot the invention.
