<P>PROBLEM TO BE SOLVED: To provide a slitter device using a cutter holder unit including a circular blade, biasing unit and stop ring in the cutter holder and capable of easily carrying out, even when there is no thickness in the radial direction or the axial direction of the cutter holder, assembling and processing, and maintaining the cutting quality of a cut member by keeping constant a pitch between the cutters and spring pressure. <P>SOLUTION: The stop ring annular groove of the cutter holder is formed with a width such that the annular stop ring is movable in an axial direction. A projected part projected from an inner peripheral side face is formed in the stop ring or at least one outer circumferential side face of the opposing side faces of the adjacent cutter holders so that when a plurality of cutter holder units are tightly fitted in a first rotary shaft, the stop ring may be moved in the axial direction of the cutter holder annular groove by the adjacent cutter holders, and that an upper blade may be locked in a prescribed position by prescribed spring pressure applied by a biasing unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
