Abstract
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.
Claims22
An apparatus on a drafting system of a spinning preparation machine with drafting system rollers forming drafting roller pairs, the apparatus comprising:
- a drive motor and transmission devices for driving the drafting system rollers, wherein the drive motor has first and second rotating drive elements, and of wherein at least a first drafting roller pair is driven from one side by the first rotating drive element and of at least one further drafting roller pair is driven from an opposite side by the second drive element.
An apparatus on a drafting system of a spinning preparation machine with drafting system rollers forming drafting roller pairs, comprising:
- a drive motor and transmission devices;
- a first drive arrangement including a first rotating drive element at one side of the drive motor;
- a second drive arrangement including a second rotating drive element at the other side of the drive motor;
- and
- wherein the first drive arrangement is arranged to drive at least a first roller pair and the second drive arrangement is arranged to drive at least one further roller pair.
