The open-end rotor spinning machine (1) has several work stations (2), each having a spinning rotor. A drive unit performs variable-speed drive of the spinning rotor. A measuring unit detects the thread breaks, and an evaluation unit detects the yarn breakage rate. A control unit sets the speed of spinning rotors automatically in dependence on the respectively determined yarn breakage rate, and regulates the yarn breakage rate, so that the yarn breakage rate is below a predetermined target range maximum fiber breakage. |
