Abstract
A spinning or twisting device in which a yarn is to be back-fed into the bore of a pipe-shaped element subjected to negative pressure in order to repair a yarn break. This pipe-shaped element is made in form of a yarn draw-off pipe of an open-end spinning device or as part of a pneumatic twisting device. A presenting device is moved over and beyond the pipe-shaped element into a yarn inserting position. The end of the pipe-shaped element towards the moving path of the presenting device is provided with a nozzle which is provided, in relation to the bore, on its side towards the yarn inserting position of the presenting device with a yarn support, and on its side away from the yarn inserting position with a yarn insertion groove, oriented in the direction of movement of the presenting device. The bottom of the yarn insertion groove is at a greater distance from the moving path of the presenting device than the yarn support.
