A fiber is manufactured by winding a strip of thin plate material made of a metal or the like around the cylindrical outer surface of a rotatably supported main shaft a large number of times and fixing it thereto, by rotating the main shaft in the direction opposite to that in which the plate material is wound at constant speed, and by feeding a cutter having an edge line thereof expending perpendicular to the axis of the main shaft and a face angle ranging between 21 degrees and 37 degrees parallel to the axis of the main shaft and at a constant speed and thereby cutting the end surface of the plate material by the cutter. In consequence, finer and soft long fiber can be manufactured effectively at a low cost. |
