ABSTRACT:
A process and device for piecing in an open-end spinning device includes switching on a fiber feeding device for a predetermined period of time so that fibers which are undesired for piecing are combed out of the leading end of the fiber sliver which is presented to an opener device. The combed out fibers are deflected from the fiber collection surface. The fiber feeding device is switched off after the predetermined period of time once the undesired fibers have been combed out and is maintained in an off condition for a short period of time so that the fibers remaining in the leading end of the fiber silver are only minimally damaged by the opener device. The fiber feeding device is switched back on and the fiber stream is deflected from the fiber collection surface as the stream increases to full strength. The fiber stream is subsequently deflected to the fiber collection surface for piecing in coordination with backfeeding of a yarn end to the fiber collection surface.
