ABSTRACT:
In the case of an apparatus on a spinning preparation machine, e.g. a draw frame, flat card, combing machine or the like, in particular a double-head draw frame, with at least two driven drafting systems having force-transmitting means for driving drafting rollers of the drafting systems and at least one drive motor, a coupling is present between a drive motor and a drive shaft. To allow the effectiveness and efficiency to be substantially increased in a structurally simple and cost-effective manner, the respective drive chains are connected via a respective controllable coupling to the motor and the rotational speed of the motor can be reduced for the engagement and disengagement process.
