ABSTRACT:
A knife (12), a holding and releasing mechanism (8) are oriented in the direction of a radius of a chipper disc (19). The holding and releasing mechanism (8) is pushed in the direction of the radius of the chipper disc to release the knife (12) and drawn in the opposite direction to fasten the knife in the chipper disc (19). A power unit (32) with reciprocable spindle (34) selectively engages a holding element (11) of the holding and releasing mechanism (8) to release the knife (12) from the chipper disc (19). A device (36) can be provided for automatically positioning the holding and releasing mechanism (8) to lie opposite the spindle (34) of the power unit (32). The time consumed in replacing the knives is reduced and laborious manual operations can be avoided. The procedure can be automated.
