Abstract
A mechanism for adjusting the position of a knife on a rotary cutterhead mounted for rotation about a central axis comprises at least three dynamics positioning points for allowing a user to adjust the knife axially, radially and tangentially with respect to the central axis of the cutterhead.

A mechanism for adjusting the position of a finger joint knife in a pocket defined in a peripheral surface of a disc body of a rotary cutterhead mounted on a spindle for rotation about a central axis, the mechanism comprising:
- at least three dynamic knife supporting points adjustable relative to the disc body, the at least three dynamic knife supporting points including an adjustable axial referencing surface at one axial end of the pocket for axial abutment against an axial end surface of the finger joint knife, and a pair of adjustable radial referencing surfaces axially spaced apart along a radially inner bottom of the pocket, the adjustable radial referencing surfaces being individually adjustable relative to one another to provide for an angular adjustment of the finger joint knife relative to the central axis.
A rotary cutterhead comprising:
- a body mounted for rotation about a central axis, the body defining a pocket in a circumferentially extending peripheral surface thereof, the pocket having opposed front and back walls extending from a radially inner bottom surface, the front and back walls spaced-apart in a circumferential direction around the body and extending axially between a first axial face to a second axial face of the body;
- a knife insert mounted inside the pocket;
- a clamp for securely holding the knife insert against the back wall of the pocket;
- an axial adjustment screw mounted in a corresponding screw receiving hole defined in one of the first and second axial face of the body adjacent to the pocket, the axial adjustment screw having a head axially engageable with an axial end of the knife insert;
- and
- a pair of radial and tangential adjustment screws projecting radially outwardly from the radially inner bottom surface of the pocket for adjusting a radially inner end of the knife insert, the pair of radial and tangential adjustment screws axially spaced-apart along the pocket.

A finger joint cutterhead comprising:
- a disc body having a peripheral surface extending circumferentially around a central axis;
- a pocket defined in the peripheral surface, the pocket having a front wall and a back wall spaced-apart in a circumferential direction and extending radially outwardly from a bottom wall and axially between opposed axial faces of the disc body;
- a finger joint knife clampingly mounted in the pocket;
- an axial knife reference surface adjustably mounted in an axial direction at one end of the pocket and configured for axial abutment with an adjacent axial end surface of the finger joint knife;
- and
- first and second radial knife reference surfaces axially spaced-apart along the bottom wall of the pocket, the first and second radial knife reference surfaces individually adjustable in a radial direction for radial adjustment of a corresponding radially inner surface of the finger joint knife.
