Abstract

For the piecing of a yarn of a spinning unit of an open-end friction spinning machine, it is provided that a yarn an brought into the wedge-shaped gap is pieced, while forming a yarn piecing, which, before a renewed winding-up of the yarn, is cut out and is replaced by a yarn connection connecting the new yarn with the yarn leading to the spool. The formation of the yarn piecing takes place at a production speed that is reduced as compared to the normal spinning operational speed, said production speed being brought to the operational value only after the making of the yarn connection. It is also provided that the yarn spun during the formation of the yarn connection is taken up by a yarn storage device, which is emptied more rapidly because of the fact that the wind-up speed as compared to the withdrawal speed has a larger speed difference than the operational wind-up speed has with respect to the operational withdrawal speed.
