ABSTRACT:
An open-end friction spinning machine having a plurality of spinning units, each having two rollers that are arranged next to one another and form a wedge-shaped yarn-forming gap is provided with a yarn guard for sensing yarn breakage in each spinning unit. In response to yarn breakage sensed by an individual yarn guard of a spinning unit, a wind-up spool is lifted off its driving roller and the rollers are stopped. Preferably, a control element is provided for lifting-off of the wind-up spool, and at the same time triggering the stoppage of the rollers and/or switching-off of a suction device arranged adjacent the wedge-shaped yarn-forming gap.
