Abstract (en)
[origin: CA2211242A1] The invention is based on the method for the resharpening of knives used in size-reduction machines described in the US Patent 5,525,094 in which the knives remain installed in a rotatable knife carrier. With this invention the process has been further developed in so far as the cutting edges S are ground one after another respectively at one stop position of the knife carrier 8 in which the radial ray MS of the cutting circle with the direction mS of the grinding feed v at the knife cutting edges S encloses the clearance angle ~. So the invention offers the possibility to chose for the cutting edges any clearance angle matching the properties of the material to be flaked. The indicated reference numbers refer to Fig. 4 of the application drawings.
