  • Patent number: 11414788
    Abstract: According to one embodiment, a spinning apparatus includes a spinning head and a rotational brush. An organic material is filled up inside the spinning head, and the spinning head ejects the organic material on a surface of a base to form a sheet of the organic fiber on the surface of the base. The rotational brush includes a plurality of brush bristles and is rotated while the brush bristles are in contact with the sheet in the surface of the base. The rotational brush strips the organic fiber from a part of the sheet by the rotation.

  • Patent number: 7082646
    Abstract: An apparatus for on card cleaning and grinding of revolving flats (4) in a carding machine is disclosed. The apparatus mounts an interchangeable rotary cleaning brush (14) or grinding wheel (16) on a wheel drive (11) so that the wheel can be spun around an axis lateral to the path of the revolving flats (4). During a carding operation the height of the cleaning brush (14) is accurately adjusted by a precision feeding mechanism so that the brush cleans down to the surface of the revolving flats of the revolving flats (4) and so cleans and polishes the wires (4b) and the fouling which commonly accumulates beneath the points (4c) of the wires. The brush (14) can readily be replaced by a grinding wheel with a peripheral grinding surface.

    Abstract: An apparatus is illustrated which is especially useful for cleaning the flats of a textile carding machine wherein a rotatable suction conduit has circumferentially spaced slots therein which are successively exposed in cleaning relation to successive flat or carding surfaces by means of a substantially imperforate flexible cover sheet extending about the rotatable suction conduit, being fixed on one end so that the cover extends as a shroud preferably extending in the direction of rotation of the conduit away from the fixed end so as to leave an opening between opposed ends of the shroud. The shroud covers the slots rendering them inactive so that only that slot portion between opposed ends of the shroud actively exert suction. Thus, the suction is concentrated at a specific area, between the ends of the cover, adjacent a limited portion of a flat while permitting rotation of the suction conduit without buildup of excessive lint accumulation as to interfere with the operation of the conduit.

  • Patent number: 3936910
    Abstract: A carding method in which the rotary flats of a carding machine are driven intermittently so that each time the flats are driven only a portion (1/6 to 1/4) of the flats opposed to the cylinder of the machine are replaced by fresh flats, thereby decreasing the amount of good fibers in the waste, particularly when carding synthetic fibers.The carding machine is provided with a solenoid clutch in the drive mechanism for the rotary flats and the flat cleaning means, and with a timer for controlling the clutch so that the flats can be intermittently driven at desired drive and stop intervals. For carding polyester fiber, the drive interval may be enough to replace one-fifth of the flats opposed to the cylinder of the machine with fresh flats, and the stop interval may be as much as sixty minutes.
