ABSTRACT:
A method and apparatus for setting the knife projection of regrindable, strip-shaped cutting tools which are each screwed releasably to a knife carrier (8) and which are releasably arranged together with the carrier, in an at least approximately radial direction, in the rotary-drivable disk (1) of a disk-type cutter. To simplify the operation and to improve the chip quality: first, each knife (4) of the disk (1) is set outside the disk-type cutter, in a single setting device, to a respective identical distance between the cutting edge (10) and the inner longitudinal edge (11) of the knife carrier (8) and is then screwed firmly to the associated knife carrier (8); second, after being installed in the disk (1), the knives (4) are successively oriented and fixed relative to a common plane (39) which is perpendicular to the disk axis (5) and which defines the first-cut face of the wood during the cutting (cutting plane); and third, the knife adjustment is carried out in such a way that the knife projection of each cutting edge ( 10) relative to the flight circle of the disk surface (3) increases outward in the radial direction over the knife length.
