PROBLEM TO BE SOLVED: To use a relatively small number of drive components and to improve efficiency. SOLUTION: In a device on a spinning preparation machine, having a drafting system for drawing at least one fibre silver with drafting system rollers, forming drafting roller pairs, having power transmission means for driving the drafting system rollers and having a drive motor, the drive of the drafting system rollers is effected from different sides. In order to reduce the number of drive elements and to effect a substantial improvement in efficiency, the drive motor has two rotating drive elements, the drive of at least one roller pair being effected from one side by the first drive element and the drive of at least one other roller pair being effected from the other side by the second drive element.
