摘要

The apparatus on a spinning preparation machine, for example, distance, card, a combing machine or the like, in particular double head section, with at least two driven the case of drafting units for the distortion of in each case at least one fiber sliver with a stretching rollers pairs in the form of the drawing-frame rollers, with force transmission means for driving the drawing-frame rollers and at least one drive motor, wherein between a drive motor and a drive shaft, an electrically actuatable coupling is present, characterized in that the respective drive trains (b, c, d, e), in each case via a controllable coupling (8, 9; 12, 13, 53, 54) with the motor (2, 3, 52) are connected and the motor (2, 3, 52) for the a - or disengagement process is in its rotational speed (v) can be lowered.
