Open-end spinning machine with a plurality of spinning units having a movable maintenance device

摘要

An open-end friction spinning machine is provided having a plurality of adjacently arranged spinning units and a movable start-spinning device capable of attachment to a spinning unit requiring service. The broken yarn end for the start-spinning process is returned into the spinning unit against the normal yarn withdrawal direction. In order to safely accomplish the return of the yarn into the area of the friction spinning region which is preferably formed by two adjacently arranged rollers forming a wedge-shaped gap therebetween, a compressed air jet is provided which returns the yarn end through the friction spinning zone.
