ABSTRACT:
In the case of a device for open-end friction spinning having two friction rollers that are arranged next to one another to form a wedge-shaped gap and are drivable in the same rotational direction, an arrangement is provided for the feeding and opening of a sliver which contains an opening roller from which a fiber feeding duct leads to the wedge-shaped gap. A compressed air duct that is led past the opening roller is connected to the fiber feeding duct for supporting the fiber transport. A dirt discharge opening assigned to the circumference of the opening roller is arranged at a distance to the compressed air duct in such a way that the effect of the excess pressure does not reach back into the area of the dirt discharge opening.
