Abstract
In an open-end spinning machine, a centralized main drive is provided to collectively drive spinning elements of a plurality of spinning stations installed next to each other. At each spinning station, a switch-over device is provided for switching each spinning station over to a stationary, centralized auxiliary drive. The main drive includes a main drive belt to collectively drive the plurality of spinning elements. An auxiliary drive belt driven at a second speed for selectively driving individual spinning units is powered by the stationary centralized auxiliary drive. Using its respective switch-over device, either the main drive belt or the auxiliary drive belt can be selected to drive a given spinning unit. Thread joining preferably takes place at a spinning unit (e.g. spinning rotor) speed relatively close to the production speed of the spinning unit so that strong thread joins and consistent thread results.
