Abstract (en)

[origin: EP2500452A1] The workstation (1) has an open-end spinning device (2) for producing a thread, and a winding device for producing a cross coil. A suction nozzle (4) is pivotably mounted and motor-driven for pneumatic reception of thread ends accumulated on the cross coil. A locking device (30) locks the suction nozzle in a predetermined rest position (29). The locking device is arranged in a region of a pivot axis of the suction nozzle. The locking device is formed as a mechanical operating device, which reliably fixes the suction nozzle when a stepper motor (28) is switched off.
