ABSTRACT:
In the case of an open-end friction spinning machine having a plurality of spinning units that are arranged next to one another and having a movable servicing apparatus carrying out a piecing process, it is provided that approximately in the extension of the yarn formation zone facing away from the withdrawal device, a twist blocking device is provided for receiving a yarn end that is returned beyond the feeding point. The device for the yarn withdrawal is switched on when the yarn end is in the yarn formation zone of the friction elements so that the yarn end is opened up into a fiberbeard that is suitable for piecing while being held by the twist blocking device.
