Abstract
In an apparatus at a spinning preparation machine, especially at a carding machine, cleaner, draw frame, combing machine or the like, having at least one electric motor-driven roller, which is rotatably mounted about its longitudinal axis, the roller is caused to rotate by means of forces of an electromagnetic field that act on at least one roller end-face. In order to achieve a substantially increased drive output and braking output and a high torque in a simple manner, an electromotive drive means is present having a rotor and a stator which are integrated into the roller and into an immobile machine element associated with the roller.
