ABSTRACT:
In the case of an arrangement for disposing and driving a spinning rotor of an open-end spinning unit which, by means of a rotor shaft, is disposed in wedge-shaped gaps formed by two pairs of supporting disks and is driven by a belt looping around it, it is provided that the belt is looped around a driving pulley of an electric motor which, with respect to the supporting disks, is arranged in the area opposite the rotor shaft and which, for the tightening of the belt, is movably held in a guide in a plane extending at least approximately through the wedge-shaped gap. A belt holding device is provided for holding the belt in a relaxed position so that the spinning rotor shaft can be readily axially withdrawn and exchanged without requiring any disassembly of the belt drive.
