ABSTRACT OF THE DISCLOSURE The invention relates to a procedure and apparatus for replacing a knife in a disc chipper. The disc chipper is provided with a disc which rotates about its center axis and on which several knives are fixed by means of knife holders and knife fixing elements. When a knife is to be replaced, a releasing device, e.g. a piston mounted inside the disc is used in such a way that it acts on all the fixing elements of one knife essentially simultaneously and in a direction essentially opposite to the direction of the force generated by the knife fixing elements.
