Abstract

The conveying means cooperate with a first blade to move the tree lengths to the overlapping peripheral portions of the blades where they are subject to a shear cutting action.
Claims12
A circular shear cutting device for cutting tree lengths comprising:
- a frame;
- a pair of circular shear blades rotatably mounted on said frame, each said blade including a periheral portion provided with a continuous cutting edge, the peripheral portions of said blades being in partially overlapping relation to one another;
- first drive means for rotating said blades in opposite direction to one another;
- means for successively conveying tree length transversely to said pair of blades;
- second drive means causing said conveying means to advance tree lengths to a first of said pair of rotating blades, said conveying means cooperating with at least one of said blade to move said tree lengths to the overlapping peripheral portions of said blades where said cutting edges gradually penetrate the conveyed tree length to effect a shear cutting action therethrough.
