ABSTRACT:
When an open-end rotor spinning device is stopped, a short yarn end is produced. For this, and in synchronization with the interruption of fiber feeding to the opener device (116), the fibers which continue to be combed out of the leading end of the fiber sliver (2), as well as the fibers still present in the clothing of the opener device (116), are prevented from continuing to accumulate on the fiber collection surface (136) of the spinning rotor (13). To carry out this process, the device (115) for the stoppage of the fiber feeding device (110) is connected to a control device (3) by means of which a device (134, 135, 172, 173) for the shortening of the yarn end can be switched on temporarily as the spinning device (11) is stopped.
