Abstract: A gas wiping nozzle for a wire coating apparatus includes an inlet portion defining a converging inlet passage for a coated wire that is axially drawn through the gas wiping nozzle. A wiping portion is further included and defines a wiping passage for the coated wire, downstream and in an axial extension of the inlet passage. The wiping portion has a gas outlet surrounding the wiping passage for blowing wiping gas onto the coated wire. A protruding annular lip is arranged between the converging inlet passage and the wiping passage, and the annular lip defining a passage for the coated wire that is narrower than the wiping passage so that the gas outlet means in the wiping passage is protected by the protruding annular lip against direct contact with the coated wire which is axially drawn through the passages of the wiping gas.

Abstract: A device for producing metal fibers from a metal wire includes a forming assembly and a cutting assembly arranged downstream from the forming assembly in the direction of production. Both the forming assembly and the cutting assembly are driven by a driving mechanism and are mechanically synchronized. The cutting assembly includes a cutting roller and a mating roller, the cutting roller having cutting elements extending radially outwardly from a circumferential surface of the cutting roller and are uniformly distributed over the circumferential surface. The cutting roller and the mating roller are arranged at a minimum distance, one above the other, where either the cutting roller or the mating roller is arranged above a travelling path of the wire, while the other is arranged below the travelling path of the wire. During fiber production, the wire passes substantially tangentially between the cutting roller and the mating roller.

Abstract: A device for producing metal fibers from a metal wire comprises a forming assembly (14) and a cutting assembly (16), said cutting assembly (16) being arranged downstream of said forming assembly (14) in the direction of production, said forming assembly (16) being driven by driving means (58). Said cutting assembly (16) is driven by said driving means (58) and said forming assembly (16) and said cutting assembly (14) are mechanically synchronized.
