ABSTRACT:
A process for cleaning an open-end spinning rotor which has a fiber collection channel and an open edge, which is covered by a rotor cover. A first compressed-air stream is directed towards the fiber collection channel in a first cleaning phase. Then, in a second cleaning phase, the spacing between the open edge of the spinning rotor and the rotor cover is increased. In addition, a suction air flow leaving the spinning rotor over its open edge is produced. To carry out this process, there is associated with the rotor cover an opening apparatus which is connected, together with at least one blower channel to a common control apparatus. Associated with the rotor cover and with the blower channel, are in each case two working positions, of which the respectively first working position is adopted during the normal spinning operation and in which a compressed-air stream which can be switched on to clean the spinning rotor and which leaves at least one blower channel directed towards the inner surface of the spinning rotor. The respective second working position is set so that the compressed-air stream leaving at least one blower channel either produces an air flow directed from the fiber collection channel towards the open edge of the spinning rotor or is guided away over the open edge of the spinning rotor.
