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.
