Abstract
A servicing device is provided for cleaning spinning rotors and spinning rotor housings of an open-end spinning machine. The servicing device includes a combined suction and blower device which alternately applies compressed air and suction forces to loosen and to withdraw fiber residues and the like from the spinning rotor and the housing. The servicing device is a mobile unit movable along a plurality of spinning units and includes a mechanism for opening the covers to the individual housings so as to expose the open sides of the spinning rotors to the combined suction and blowing device which is movable into position to perform cleaning operations. In order to assure control of the suction and blowing of cleaning air during cleaning operations, the cleaning device includes a suction flange which covers the housing of the spinning rotor in the manner of a lid when in the servicing position.
