摘要

The woodchip chopper (1) has a rotor (3) on which a cutting blade (2) is fitted for working in conjunction with a counter steel (8), fitted in the vicinity of wood feed-in rollers. To avoid adjustment of the counter steel and blade during sharpening, an edge area, which thrusts up to the blade edge (6) is raised parallel with the blade first side surface (18), which is located against the rotor side surface (15).
