  • Set of cutters for a canter head
    Patent number: 8684051
    Abstract: The present invention relates to a cutting device for a fast canter head (20) comprising a knife holder (22) directed at an angle, a counter knife (30) with an elbow and a dorsal support (37) which positions a cutting knife (50) having a cutting angle (54). The cutting knife has a pair of adjustment recesses (52) containing an adjustment device (58). The adjustment device comprises an end of support (64) which leans against the dorsal support and works like a compensator to take into account any wear of the cutting angle of the knife for a constant distance grinding operation, in an adjustable position, making it possible to preserve a same rotation distance. The adjustment device has a railing guide (70) which slips into the adjustment recess (52) and which comprises an elastic wall (72) which pushes against the sides of the recess by the action of a tightening conical element (76) activated by a conical set screw (78). In the event of shock, the guide slips.
