ABSTRACT:
In an open-end spinning machine (1) with a plurality of open-end spinning devices (3), each having a spinning rotor (15) whose rotor shaft (26) is seated in the bearing wedge of an axial thrust-free support disk bearing (27) and is positioned by a magnetic bearing (29), and a service unit (10), which automatically services the spinning devices, a sensor device (41) is provided on the service unit (10), which is connected to the control device (18) of the service unit (10) and checks an identification marker (34) applied to each spinning rotor (15). The control device (18) actuates a yarn piecing operation by the service unit only upon detection of an identification marker (34) identifying the spinning rotor (15) to be compatible with the associated spinning device.
