Abstract: The present invention provides a canter chipper head that comprises a rotor suitable for rotation about a rotation axis. The rotor has a lateral side and a frontal side, and includes a first cutting assembly and a second cutting assembly that are each mounted to the rotor. During rotation, the first cutting assembly defines a first lateral cutting surface around the rotation axis, and a first frontal cutting surface that is generally transverse to the rotation axis. The first lateral cutting surface and the first frontal cutting surface perform a primary cut in a log. The second cutting assembly defines a second lateral cutting surface around the rotation axis, and a second frontal cutting surface that is generally transverse to the rotation axis. The second lateral cutting surface and the second frontal cutting surface perform a secondary cut in the log that is deeper than the primary cut.

Abstract: A lumber unscrambler and conveyor having first and second rigid units mounted at an incline on a support structure. Each unit has a plurality of spaced apart parallel plates in series along the incline and parallel thereto. The plates on the respective first and second units are inter-leaved in alternate relation. The plates have an upper article supporting surface and a leading edge generally transverse to the incline. The leading edge of plates proximate the in-feed end are of greater depth than those further along the path toward the out-feed end. The units are supported on the support structure to move relative thereto and one another. The units are driven in synchronized out of phase relation reciprocating along the inclined path. A hopper at the in-feed end receives and holds a supply of lumber pieces of selected dimension and as the plates reciprocate they move pieces of the lumber from the hopper to the out-feed end discharging normally only a single stick one after another.

Abstract: The present invention relates to a log-processing machine that includes a frame and at least one cutting head that is movable in relation to the frame along a path of travel. The path of travel includes a horizontal displacement component and a vertical displacement component and defines a plurality of log engaging positions. For example, the at least one cutting heads are movably mounted to the frame via at least one pivot, whereby the path of travel is defined by the cutting head's movement about the pivot. The log-processing machine is adapted to receive end loaded logs, such that when the at least one cutting head is in engagement with a log, a relative movement between the log and the cutting heads in a longitudinal direction of the log causes the cutting heads to cut away a side of the log.
