PURPOSE:To continuously manufacture metal fiber for nonwoven mat providing suitable toughness by rotating a rotating shaft winding metal-made strip material by multiple turns toward reverse direction to the winding direction and cutting end face of the winding material with a cutting edge. CONSTITUTION:The metal material of brass-made strip, etc., is tightly wound to a main shaft 10 by multiple turns and the end part thereof is fixed to the surface of the shaft. The main shaft 10 is rotated toward reverse direction to the winding direction of the winding material 20 at the fixed velocity. The cutting edge 51 is pushed to the end face 20a of winding material 20 to cut each layer of the metal material 20 concentrically laminated at the same time. By this method, long fiber having fiber diameter according to the thickness of winding material 20 can be continuously manufactured. At the time of forming this metal fiber to the suitable shape, sufficient strength is displayed with mutual combination caused by interwining among themselves and the nonwoven mat without any detaching of the fiber can be manufactured. |
