ABSTRACT:
For the stopping and starting of an open-end friction spinning unit or of a spinning machine consisting of a plurality of such open-end friction spinning units, it is provided that the switching-off of the drives takes place in such a controlled manner that the yarn end forming by means of the switching-off of the fiber supply remains in the sphere of action of an auxiliary suction device. As a result, the restarting and the connected piecing are facilitated since the yarn end, in a controlled manner, remains inside the spinning unit and does not have to be returned by additional means. The yarn end is sucked into an auxiliary suction device and is preferably clamped in at least during the stoppage of the spinning unit or of the machine.
