Abstract: A device and method for spreading a fibre bundle spread, the fibre bundle being from a fibre bundle supply to a fibre take-up by way of a resistance device, having a first impulse drive that interacts with the resistance device, the fibre take-up being disposed downstream of the resistance device. The fibre bundle by means of the impulse drive during spreading is superimposed in an alternating manner in predefined sequences with an additional speed component in the conveying direction of the fibre bundle and/or with an additional speed component counter to the conveying direction.

Abstract: Described are a device and a method for spreading a fibre bundle. In the case of the device, the fibre bundle is fed from a fibre bundle supply to a fibre consumer 5 by way of a resistance 3, having a first impulse drive 4.1 that interacts with said resistance 3, said fibre consumer 5 being disposed downstream of said resistance 3. The fibre bundle 1 by means of the impulse drive 4.1 during spreading is impingeable in an alternating manner in predefinable sequences with an additional speed component in the conveying direction of said fibre bundle and/or with an additional speed component counter to the conveying direction.

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.
