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.
Claims39
A flat cleaning apparatus for a card comprising
- a comb for loosening waste fiber on the flats of a revolving flat system;
- a suction-extraction means downstream of said comb relative to the direction of movement of the flats for for movement longitudinally across the flats of the revolving flat system, said means including at least one suction nozzle for drawing-in loosened waste fiber from the flats of the revolving flat system;
- and
- a rotatable brush in communication with said suction nozzle for extracting deep-seated dirt from between the flats of the revolving flat system.
A flat cleaning apparatus for a card comprising
- a comb for loosening waste fibers on the flats of a revolving flat system;
- a casing having at least one suction nozzle downstream of said comb relative to the direction of movement of the flats for drawing-in loosed waste fiber from the flats and a chamber downstream of and in communication with said suction nozzle relative to said direction;
- a rotatable brush downstream of said suction nozzle relative to said direction for extracting dirt from between the flats, at least part of said brush extending within said chamber to deliver extracted dirt to said suction nozzle within said casing;
- and
- means for moving said casing transversely of said comb longitudinally across the flats.
In a card, the combination of
- a revolving flat system having a plurality of parallel flats having a clothing thereon;
- a comb disposed above said system for loosening waste fibers on said flats;
- a casing disposed above said system downstream of said comb relative to the direction of movement of the flats, said casing having at least one nozzle for drawing-in loosened fiber and dirt from said flats and a chamber downstream of and in communication with said suction nozzle relative to the direction of movement of the flats;
- a rotatable brush for extracting dirt from between said flats and having at least one part extending within said chamber to deliver extracted fiber and dirt to said suction nozzle within said casing;
- and
- means for moving said casing across said system longitudinally of said flats.
