Abstract

A spinning point of a spinning machine includes a spinning unit, a drawing-off device for the yarn downstream of the spinning unit and a yarn storage downstream of the drawing-off device for the intermediate storage of a section of yarn. The yarn storage has a sensor system for monitoring the filling level of the yarn storage (7). The spinning point includes a winding device for the yarn downstream of the yarn storage, along with a return unit, with the assistance of which an end of the yarn found within the yarn storage after a yarn break is returned into the area of the spinning point. The winding device (9) is stopped in the case of a yarn break in such a manner that, after the stop, an end section of the yarn remains within the yarn storage (7). Subsequent to this, a part of the yarn is separated with the assistance of a yarn separation unit internal to the spinning point, and that the end of the yarn that newly arises in this manner is returned with the assistance of the return unit internal to the spinning point into the area of the spinning point, and that a piecing process is then carried out.
