Abstract
The flat cleaning apparatus employs a comb for loosening fibers and dirt particles carried by the revolving flats of the revolving flat clothing. In addition, a casing which travels across the width of the revolving system has a suction nozzle for drawing up the loosened strips of fibers and dirt particles. In addition, a brush is provided downstream of the suction nozzle which is movable relative to the flats to clean between the flats so as to release deep-seated dirt after the strips are removed. The brush is mounted in a chamber which communicates with the suction nozzle so that a suction force is available for removing the deep-seated dirt brought up by the brush.
