A method for automatically exchanging flaking knives in a knife ring of wood flaking machines in which the knives are attached to respective knife holders in a force-locking connection comprises the following steps: Loosening the force-locking connection between the flaking knife and the respective knife holder; automatically removing the flaking knife from its holder; automatically exchanging the removed flaking knife for a sharpened flaking knife; automatically inserting the sharpened flaking knife into the knife holder; and, depending on the wear of the wall portion, automatically positioning the sharpened flaking knife in the knife holder such that a cutting edge of the flaking knife protrudes relative to the adjacent inner wall surface of the knife ring to an extent that corresponds to the desired cutting depth. The exchange device for carrying out this method is comprised of a knife ring with knife holders and flaking knifes fastened to the knife holders; a device for receiving the knife ring; a support connected to the receiving device and insertable into the interior of the knife ring when the knife ring is received in the receiving device; a transport mechanism and an adjusting device connected to the support; an ejecting device connected to the receiving device and positioned at an outer circumference of the cutting block; and an exchange magazine slidably mounted on the receiving device and slidable in a direction transverse to the axial direction of the knife ring.
