ABSTRACT:
An open end rotor spinning machine with plural workstations each having a yarn spinning device, a yarn take-off mechanism loaded by a reversibly driven single drive and a winding device for producing a cross-wound bobbin. The spinning device has a spinning rotor, a fiber band opening roller and a single motor-driven fiber band feed cylinder. Each workstation (2) has a mechanism (10) for cutting to length a yarn (30) retrieved from the bobbin (22), a yarn storage mechanism (37) and a drive mechanism (7) for lifting the bobbin (22) from its drive roller (23). During the piecing process, a manually activatable control mechanism (9) activates the drive (19) of the yarn take-off mechanism (18), the drive (15) of the fiber band draw-in cylinder (14) and the drive mechanism (7) to lift the bobbin (22) according to a predetermined piecing program.
