Abstract:
A disk-shaped rotary blade of a slitter blade assembly has a cutting edge and a first beveled surface facing a drum-shaped rotary blade of the slitter blade assembly and progressively spaced from the drum-shaped rotary blade toward the cutting edge. The disk-shaped rotary blade also has a second beveled surface facing a workpiece to be cut off and progressively spaced from the cutting edge away from the workpiece.

Abstract:
A plurality of upper slitting blades and a plurality of lower slitting blades are located such that each of the upper slitting blades stands facing one of the lower slitting blades. The upper slitting blade and the lower slitting blade, which stand facing each other, are located such that a cutting edge vicinity region of the upper slitting blade and a cutting edge vicinity region of the lower slitting blade overlap each other in a radial direction. The plurality of the upper slitting blades and the plurality of the lower slitting blades are rotated to slit a magnetic tape web into magnetic tapes. A cutting edge of each of the upper slitting blades and/or a cutting edge of each of the lower slitting blades has a curved shape.
