Abstract
A method for controlling a ring spinning frame that has a drafting unit, a spindle, and a ring rail is provided. The method involves providing a clamping device for yarn in a position below a cop on the spindle. The method further involves the driving of the drafting unit, the spindle, and the ring rail in coordinated operation. Also included is changing the twisting of the yarn in order to obtain a matched strength during formation of the reverse winding at the end of the winding cop before reaching the cop bottom port within the last phase of the downward movement of the ring rail. Additionally, the yarn is brought into a section of the clamping device, and the spinning frame is slowed to a standstill. A spinning frame is also provided.
