Abstract (en)
[origin: US4644742A] When a thread is joined in an open-end spinning device, the thread is fed back into the open-end spinning device as a result of reverse rotation of a bobbin and a pair of auxiliary rollers. After the feedback has ended, the thread is released by the pair of auxiliary rollers and, until normal spinning draw-off is started, the thread is subjected to an auxiliary draw-off at a greater distance from the open-end spinning device than the normal spinning draw-off. This auxiliary draw-off can be carried out exclusively by means of the bobbin or also independently of it. An auxiliary draw-off device serves for generating this drawing force and is located at a greater distance from the open-end spinning device than the pair of draw-off rollers.
