Furthermore, due to the segnentweieo or interrupted arrangement of the carriers in which the machine is also operated at high working speed p, u a? lfaohteil la structure of the same. Accordingly, the maximum working speed and the production capacity of the door direction or machine are limited

The aim of the invention is therefore an improved Wendelassrchine and an improved method in which the bobbins with the thread material have only been rotated about their own axes "so that the machine can be operated at a much higher operating speed for longer periods of time than machines" as previously used for this purpose suggested and used. The result is a significantly higher yield and production capacity as well as at the same time

Rotation is the thread material F through the respective

fixed mandrels 5 unwound from the respective bobbins and wrapped around the mandrels, forming a series of

Turns of thread material on the thorns, like. in Fig. 7

it is understandable that the distance from the respective ™

respective mandrels 5 »as shown in Fig. 7, during a

Part of one revolution is greater than during the other Part of the turn, since the mandrels 5 in a point auceer-

As a result, the thread material undergoes F around the mandrels

The coiled threads C then run along the respective mandrels 5 and from the end of the same into the respective openings and cavities of the Fownrades 6 and under the flexible band 2o. The coiled threads C are guided next to one another by the RcS 6, preferably at 360 °, to a point directly under the thorns 5, where they are loosened or removed from the tubes by a device 27 and by a device 28 preferably attached there brought into engagement with each other εο that they are connected to each other «

From the foregoing explanations it is clear that the circumference of the forjar wheel 6 is heated and that the coiled threads C, while being passed around it, are "heated to soften them" auozuliärtQE. and to solidify, so that any tension in the thread material is absorbed.
