Abstract
The start-stop program for the open-end spinning machine causes the external suction means to be rendered ineffective during the stopping process before the rotor falls below a speed necessary to maintain tension in the fiber ring in the fiber collecting groove of the rotor. Also, the program causes the external suction means to be effective on the rotor during a start-up only after the rotor has reached a speed sufficient to maintain the fiber ring tensioned in the collecting groove.
