A method for mounting a wear plate and a knife base on a disc chipper's disc, and a disc chipper. The wear plate (6) rests against the knife base (4) via two counter surfaces (12), one of which forms in the wear plate (6) a groove in parallel to the knife (3) and the other forms in the knife base (4) a ridge which can be fitted into this groove. The tightening force of fastening bolts (17, 18) of the wear plate (6) presses the knife base (4) against the disc (1) by means of the wear plate via these counter surfaces (12).
L'invention concerne une écorceuse à disque et un procédé de fixation d'une plaque d'usure et d'une base de couteaux sur le disque de cette écorceuse. La plaque d'usure (6) repose contre la base de couteaux (4) par deux contre-surfaces (12), l'une d'entre elles formant dans la plaque d'usure (6) un sillon parallèlement aux couteaux (3), et l'autre formant dans la base de couteaux (4) une saillie qui peut rentrer dans le sillon en question. La force de serrage exercée par les boulons de fixation (17, 18) de la plaque d'usure (6) comprime la base de couteaux (4) contre le disque (1) par le biais des contre-surfaces (12) de ladite plaque.
