摘要： 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.

摘要： A mote knife arrangement is fitted to a flat of a card or carding machine in a position so as to extend substantially transversely to the carding direction and the mote knife or blade is at an inclination so as to extend in a direction substantially opposite to the carding direction. A steel profile defining the mote knife or blade is provided for the mote knife arrangement. The steel profile is positively and non-slidably retained at a support or carrier which is mountable at the associated flat. The steel profile provided for the mote knife arrangement is retained at the support or carrier by permanent plastic deformation of such support or carrier which has a predetermined profile or sectional shape. The longitudinal direction of the profiled support or carrier also extends substantially transversely to the carding direction.

摘要： A cleaning device serves for cleaning sensing or sensor rollers which are mutually biased towards each other and between which travels a fiber sliver. Roll cleaning is effected by means of a scraper blade which, in accordance with the invention, is moved intermittently into a scraping position and away therefrom. This provides the advantages of reduced wear on the scraper blade provided at the cleaning device and also reduced wear on the peripheral surface of the associated sensing or sensor roller which is to be cleaned.

摘要： In a card, to avoid passage of fibers or fiber flocks over the edge of clothing into a gap, a covering band is pressed against an internal surface of the fiber-guiding roll or cylinder and a surface lying opposite the fiber-guiding roll. The covering band covers the gap between the fiber-guiding roll and a side wall portion. Two forwarding grooves, lying opposite one another in the gap and having transport surfaces lying opposite one another in crossed fashion, return fiber flocks which may possibly pass into the gap to the upper surface. A forwarding pin is set into the roll surface 7 of the fiber-guiding roll outside the edge of the clothing at such a inclination that fibers or fiber flocks which can pass into this region are transported by such pin towards pointed clothing of card flats.

摘要： The converging space between the moving-in or inbound surface of a loosening roll and the surface of a feed roll contains a suction duct, which is brought into close vicinity of the fibre loosening zone located between the two rolls, and which is used for sucking off of dust released in this zone. The suction duct is supported by the body forming the fibre feeder trough. Detrimental deposits of impurities in the subsequent processes, e.g. in the open-end spinning rotors, thus are greatly reduced.
