ABSTRACT:
In an open-end friction spinning machine having a plurality of spinning units, each containing two friction rollers that are arranged next to one another, form a wedge-shaped gap and are drivable in the same rotational direction by means of a belt drive, a common belt drive is employed. Each spinning unit is equipped with an automatic disengaging device for disengaging the belt drive of that unit. This disengaging device contains at least one spring-loaded tension pulley holding the belt drive in the driving position. The operational position of the tension pulley is secured by means of a locking device, and the tension pulley is automatically disengaged from the drive belt when the locking device is opened.
