ABSTRACT:
An open-end spinning device includes a spinning rotor having an axis of rotation, a bottom face and a lateral sliding face conically widening toward the bottom face and intended for receiving fibers which have been fed into the spinning rotor. A fiber collecting groove is located between the bottom face and the sliding face. A blast air opening having an axis is disposed on a stationary part of the spinning device adjacent to an inner chamber of the spinning rotor for feeding air to blow fibers and foreign bodies from the fiber collecting groove. A shallow, concave curve defines an inwardly curved portion of the bottom surface of the spinning rotor between its axis of rotation and the fiber collecting groove. The axis of the blast air opening is directed toward the inwardly curved surface of said bottom.
