ABSTRACT:
A process and apparatus for piecing a yarn at a spinning unit of an open-end friction spinning machine is disclosed. Before the return of the yarn end, the wedge-shaped yarn forming gap is exposed by moving away a lid-type component containing at least one part of the fiber feeding channel, after which the yarn end is introduced into the mouth of the fiber feeding channel of this lid-type component, and subsequently, the lid-type component is returned to its position covering the wedge-shaped gap. Subsequently, the actual yarn piecing process is carried out by switching on the yarn withdrawal device and the yarn feeding device as well as by the transfer of the end of the yarn end to the wedge-shaped gap.
