摘要： An apparatus and a process is disclosed for making fine metallic fibers comprising forming a continuous tube about a plurality of coated metallic wires for providing a first cladding. The first cladding is drawn for reducing the outer diameter and for diffusion welding the coating within the cladding. The tube is mechanically removed to provide a first remainder. The first remainder is drawn for reducing the diameter thereof to transform the plurality of metallic wires into a plurality of fine metallic fibers. In one example, the diffusion welded coating is removed for providing the plurality of fine metallic fibers. In another example, a plurality of the first remainders are assembled and a continuous tube is formed about the first remainders for providing a second cladding. The second cladding is drawn for reducing the outer diameter. The tube is mechanically removed to provide a second remainder. The second remainder is drawn for reducing the diameter thereof to transform the plurality of fine metallic fibers into a plurality of ultra fine metallic fibers. The diffusion welded coating is removed for providing the plurality of ultra fine metallic fibers.

摘要： A process for making fine metallic fibers comprising coating (11) a plurality of metallic wires with a coating material. The plurality of metallic wires are jacketed (12) with a tube for providing a cladding. The cladding is drawn (13) for reducing the outer diameter thereof. The cladding is removed (14) to provide a remainder comprising the coating material with a plurality of metallic wires contained therein. The remainder is drawn (15) for reducing the diameter thereof and for reducing the corresponding diameter of the plurality of metallic wires contained therein. The coating material is removed (16) for providing the plurality of fine metallic fibers.
