摘要： A process for piecing a broken yarn on an open-end spinning device in which the fiber feed to the fiber collection surface, and which has been interrupted during stoppage of the open-end spinning device. The fiber feed is switched back on and is immediately brought to full production speed. In this process the combed-out state of the fiber tuft at the point in time of when fiber feed is switched back on is ascertained. The point in time when yarn draw off is switched back on and the speed of it are adapted to when the feeding of fibers to the fiber collection surface becoming effective. The yarn is subjected to a multi-phase acceleration. The first phase of the draw-off acceleration is adapted to the incorporation of fibers into the back-fed yarn end. At least one additional phase of the draw-off acceleration serves to reach and/or to maintain the desired fiber mass. The control device to carry out the piecing process is connected to a device for the ascertainment of the combed-out state of the fiber tuft at the moment of piecing and the control device controls the yarn draw-off as a function of this ascertained combed-out state of the fiber tuft. At least two yarn accelerating devices are provided which can be selected by the control device.

摘要： For piecing a thread in an open-end spinning apparatus having a fibre collection surface, a sliver is supplied to the clothing of an opening cylinder and opened thereby into fibres and is supplied in this form to the fibre collection surface. There, the fibres are incorporated into the end of a returned thread which is then drawn off continuously. During this, the leading end of the sliver, forming a tuft, is supplied for piecing to the opening cylinder, at a penetration depth which is greater than the penetration depth after piecing, whereas piecing is carried out in a manner conventional per se, matched to a reduction in the penetration depth. This reduction in the penetration depth is carried out suddenly in order to counter thick points in the joint. To carry out the process, a penetration depth alteration apparatus is provided which is in controlled connection with a control apparatus.
