摘要

A card suitable for cleaning cotton fibers and other fibrous materials is provided. The card comprises fixed carding flats adjacently disposed about a peripheral portion of a rotatable cylinder adapted to receive clothing on the surface thereof. Each of the flats comprises a group of spaced parallel blades arranged in alternate sequence with a group of distance or separator pieces and held fast thereto. The fixed carding flats are characterized by a forward end face with the spaced blades extending to the end face, the end face being disposed against the rotational direction of said cylinder. The forward end face of each of the carding flats is inclined such that the blades extending to the end face are disposed at an acute angle relative to the clothing fed to the surface of said cylinder for removal of impurities therefrom.
