Rotary blade for cutting machines of plants, in particular for a grinder forestier.

摘要

The invention relates to a rotating cutter including a rear, fixing portion and a front, cutting portion, particularly for equipping rotors of forestry shredders. In accordance with the invention, the front cutting portion (104) has a tile-like overall shape exhibiting, in transverse section, a profile with concavity pointing downwards, so that the lower face of this portion is reduced to two end facets (106), the outer edge (107) of which defines the cutting edge of the cutter: by virtue of such an arrangement, wear of the end facets (106) thus naturally sharpens the associated cutting edges (107).
