ABSTRACT:
An arrangement for open-end friction spinning having rollers that are rotatably arranged next to one another in fixed relation is provided wherein the fiber feeding duct assigned to the wedge-shaped gap is also mounted stationarily. As a result, inaccuracies are avoided in adjustment of the mouth of the fiber feeding duct with respect to the wedge-shaped gap. For cleaning of the fiber feeding duct and the wedge-shaped gap, it is provided that the fiber feeding duct is connected to a compressed-air supplying pipe so that a jet of compressed air is blown through the fiber feeding duct into the wedge-shaped gap.
