Claims

[Claims for Utility Model Registration] 1. In a rotary cutter comprising a plurality of cutting blades 3, 5 on the outer periphery of a rotary blade 1, at least two intermediate cutting blades 3 are arranged in a point-symmetrical device. In addition, the blade width W1 of the cutting edge 4 is set to a width that can cut only approximately the center portion of the cutting width WO, while the remaining outer cutting blades 5 excluding the intermediate cutting blade 3 are cut only on both sides of the cutting width WO. It has a pair of cutting edges 6 capable of cutting the blade, and the thinning width Wc of the thinning part 7 between the double-edged blades 6 is formed to be smaller than the blade width Wa of the intermediate cutting blade 3, and the cutting blade of the rotary blade 1 Mounting surface 12.
A rotary cutter for cutting, characterized in that positioning means is provided between the cutting blade 17 and the rear surface of each of the cutting blades 3.5. 2. In the rotary cutter for cutting described in item 1, a positioning protrusion 14 that can be fitted into the positioning groove 13 provided along the radial direction of the mounting surface 12;
The rear surface 15.16 of the intermediate cutting blade 3 and the outer cutting blade 5
be provided for each. 3. In the rotary cutter for cutting described in item 1, the positioning groove 18 provided on the mounting surface 17 so as to be substantially parallel to the axial direction is provided with a positioning protrusion 19 that can be fitted into the positioning groove 18 in the intermediate position. Provided on the rear surfaces 20 and 21 of the cutting blade 3 and the outer cutting blade 5, respectively.
