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 () has a mechanism () for cutting to length a yarn () retrieved from the bobbin (), a yarn storage mechanism () and a drive mechanism () for lifting the bobbin () from its drive roller (). During the piecing process, a manually activatable control mechanism () activates the drive () of the yarn take-off mechanism (), the drive () of the fiber band draw-in cylinder () and the drive mechanism () to lift the bobbin () according to a predetermined piecing program.
