<p>A knife cutter for the angular profiles includes a plate, generally triangular in shape, the posterior surface of which has a prismatic projection corresponding to one of the sides thereof. The side and the prismatic projection are arched in order to adjust in a complementary recess made for such purpose in the front surface of the knife bearing plate. The other two sides of the knife or the cutting edges thereof form a dihedral and are parallel to the cutting edges of a counter-knife.</p> |
