ABSTRACT:
The invention concerns a device for sharpening of knives, which are mounted in the knife ring of a chip cutter and whose cutting edges run essentially parallel to the knife ring axis. Several grinding tools can be run intermittently and simultaneously in the direction of the knife ring axis in order to sharpen individual knives The knife ring stands still during the sharpening and is rotated around its own axis during the pauses between sharpening corresponding to the distribution of the knives over the periphery of the knife ring. Any grinding tool sharpens any knife in such a way that the desired total (amount of) removed grinding material is achieved with the last grinding tool in the peripheral direction of the knife ring.
