PROBLEM TO BE SOLVED: To provide an apparatus, which is of simple construction and inexpensive, and permits the effectiveness and efficiency to be considerably increased.;SOLUTION: The apparatus on a spinning machine, for example, a draw frame, flat card, a combing machine, or the like, in particular a double-head draw frame, has at least two driven drafting systems for drafting at least one fiber sliver with a pair of drafting rollers, and has a force-transmitting means for driving the drafting rollers, and at least one drive motor, wherein an electrically operable coupling is present between driving 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.;COPYRIGHT: (C)2009,JPO&INPIT
