DEBRANCHING CURVED BLADE, ITS APPLICATION, CORRESPONDING DEBRANCHING HEAD AND CUTTING SET Russian patent published in 2019 - IPC A01G23/95 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a debranching curved blade, to use of said curved blade, to a debranching head provided with at least one such blade, as well as to a cutting set comprising at least one such blade. Curved blade comprises cutting edge, at least one part of which comprises continuous flange forming continuous cutting edge, as well as at least one row of ribs, which longitudinal axes are straight and parallel to each other and which extend in direction of at least one surface of cutting edge from this continuous flange. According to the invention, the blade allows reducing the cutting force compared to the rib-free curved blade used in the prior art. Namely, continuous edge is connected with ribs, which serve to reduce lateral load of this continuous edge.

EFFECT: therefore, it is possible to provide size of flange and edge without any risk of breakage, so that to have reduced surface of contact with wood, which improves material cutting.
