Claims

[Scope of utility model registration request]

A plurality of knives with a cutting edge angle of 90° are mounted at a predetermined pitch on a pair of drums that are placed opposite each other across the material pass line, and when cutting the material, the cutting edge of the knife runs along a straight line connecting the center of the drum. In a material rotary cutting device that rotates the drum synchronously so that the material passes through the material at the same time, the knife is moved around the outer periphery of the drum so that the rake face of the knife faces the material when the cutting edge of the knife reaches the material cutting start point and material cutting end point. A material rotary cutting device characterized in that it is mounted on a drum at an angle from a right angle direction.
