Abstract (en)
The invention relates to a procedure and apparatus for replacing a knife (3) in a disc chipper. The disc chipper is provided with a disc (1) which rotates about its center axis and on which several knives (3) are fixed by means of knife holders (2) and knife fixing elements (10). When a knife (3) is to be replaced, a releasing device, e.g. a piston (12), mounted inside the disc is used in such a way that it acts on all the fixing elements (10) of one knife (3) essentially simultaneously and in a direction essentially opposite to the direction of the force generated by the knife fixing elements (10). <IMAGE>
