Abstract (en)
The disc cutter structure of the present invention includes a rotation axis (C), a supporting shaft (4) extending in a direction that crosses the rotation axis (C), and a cutting member through which the support shaft (4) is axially passed, and the cutting member has a plurality of rotary blades (1, 2) rotatable around the support shaft (4) as the center. According to the disc cutter structure, the respective rotary blades (1, 2) are rotated independently, therefore the life of the cutting member can be extended. <IMAGE>
