摘要

In the case of a device to 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 roller and at least one drive motor, is arranged between a drive motor and a drive shaft, an electrically actuatable coupling available.In order in a constructively simple and cost-effective manner, a considerable increase in the effectiveness or of the nutzeffektes, the respective drive trains, in each case via a controllable clutch is connected to the motor and the motor for a - and can be lowered in its rotational speed and uncoupling operations.
