ABSTRACT:
A method of resharpening the knives in a chipping machine while they are installed in the knives' rotor is disclosed. For this purpose all knives are moved forward one after another to their functional position by an amount that corresponds to the wear of the edges. As part of this, the radial grinding feed which is required in order to achieve the desired protrusion of the edges above the relevant area of the knives' rotor is pre-programmed based on the detected state of wear. A device to implement this method is also disclosed. The device comprises a rotational disk for the knife rotor placed on top of a machine frame and where an equipment table is provided that supports a cross-wise translatory moveable grinding unit, as well as a radially moveable adjustment device which has a sensor to determine the state of wear of the relevant area of the knife rotor 8 and a stop face to limit the knife feed.
