Abstract:
Technical Field: A reinforced fiber sheet used as a reinforcing material of the fiber that reinforces a composite material that is manufactured following the carding of bundled fibers. Technical Problem: Provide a carding machine that smoothly produces a carded sheet from the bundled fibers of reinforced filaments. Solution Method: One or more supportive part (254) is placed in a plane or a crescent form at certain intervals along the moving direction of the bundled fibers in a carding unit (25) to card them with a fluid before and after the supportive parts, improving the carding efficiency. Major Application: Aerospace, land transportation, shipping, building, construction, industrial parts, and sporting goods.
Abstract:
By combination and interaction of mechanical and aerodynamic forces, textile fibers are doffed from a processing cylinder, purged of foreign matter, subdivided and directed into a network of conveying tubes, and distributed to a multiplicity of fiber by-passing condensers wherein fibers are continuously assembled into a uniform ribbon for subsequent textile processing. The invention encompasses unique means for by-passing excess fibers for collection and reprocessing.
Abstract:
An electrostatic opening and short fiber separation apparatus for carding machines making use of a high voltage electrostatic field; which produces different forces on filaments, short fibers, and dust; in cooperation with a plurality of suction devices to separate short fiber. The apparatus is to be installed in front of a card cylinder where a doffer and a sliver forming mechanism have been removed. By means of a specially designed stripping roller, fibers are stripped from the cylinder and float across the electric field due to the attraction of suction devices. Cotton fibers in the electric field will be affected by the high voltage and held by upper and lower circular metal screen conveyor belts, to move forward. Short fibers and dust move to and fro between two metal strips due to the existence of the electric field; they will be taken up and removed if the drag force of suction devices is larger than the action force of the electric field. By this way, long staple will be sent to the cage roller in front to form webs and then formed into sliver. Most sizes of short fibers removable in the apparatus are under half an inch and therefore can effectively control the short fiber content, promote fiber parallelization, and assure the fiber quality.
