Abstract
In an open-end spinning apparatus provided with a spinning rotor rotatably disposed in a rotor housing and a combing roller rotatably disposed in a frame body, a spinning chamber being formed when the frame body is combined with the rotor housing when the normal spinning operation is carried out, when it is required to remove impurities from the inside wall of the spinning rotor, firstly the frame body is displaced away from the rotor housing and simultaneously a receiving plane is created at a position adjacent to the opened rotor housing, where suction force is being applied, and secondly, the impurities are removed from the spinning rotor and accumulated on the receiving plane so that the received impurities are carried outside of the spinning apparatus by the suction force.
