Abstract
In a device for the piecing of a yarn on an open-end spinning device, a yarn mover by means of which a yarn end is fed to a yarn draw-off pipe is provided. A first stop to determine the cutting position and a second stop to determine the yarn insertion position are assigned to the yarn mover. The first stop can be put out of action. In addition, a yarn length adjusting device is provided to determine the length of yarn to be fed back into the open-end spinning element. The cutting position and the yarn insertion position of the yarn mover are set for the smallest size fiber collection surface of the open-end spinning element that can be used. When larger fiber collection surfaces are used, the additional required length of yarn is readied by rotating the winding device backward.
