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.

Abstract: The ring spinning method drafts a sliver in a multi-stage drafting system where the sliver acquires a total draft in a range of from 60 to 150-fold. Following outlet from the last nip of the drafting system, the drafted sliver is conveyed without drafting over a guide path in which the fiber band is condensed to form a compact fiber strand of not more than 2.5 millimeters width and preferably less than 1 millimeter in width. At the end of the guide path, the fiber strand passes through a twist inhibiting nip between two rollers and is then passed by twist distribution to a ring spinning device. The yarn produced possesses a quality with respect to hairiness and neps.

At the end of the guide path, the fiber strand passes through a twist inhibiting nip between two rollers and is then passed by twist distribution to a ring spinning device. The yarn produced possesses a high quality with respect to hairiness and neps.

Abstract: The cap of a cap spinning device comprises a thread introduction attachment in the top or upper region of the cap. In this thread introduction attachment there is arranged an inlet passage which is upwardly directed at an inclination and provided for the thread coming from the drafting arrangement via a thread eye, so that a balloon is formed between the thread eye and the top or upper side of the cap.
