Abstract
The present invention relates to a process to piece a yarn (2) to an open-end spinning device (1), in which a plurality of handling devices (4) on a service unit (3) traveling alongside a plurality of identical open-end spinning devices (1) execute different work motions and in which a yarn end is taken over by a presentation device (31) and is conveyed to the open-end spinning device (1), and is then returned into same for piecing. In this process all the handling devices (4) go through a joint motion phase and if necessary through an individual motion phase. To carry out this process the handling devices (4) are mounted on a common bearing device (5) which can be moved back and forth between at least two work positions (I, II) by means of a drive arrangement (50) controlled by the control device (6).
