Abstract: A method of forming cants slabbed on four sides from logs, and a sawmill assembly for effecting formation of the cants. First and second in-line sets of pairs of saws are provided, and a log is fed to the first set of saws in a horizontal direction, the first set of saws slabbing two opposed sides of the log. The log is continuously fed from the first set of saws to the second set of saws in the same horizontal direction, and the log is rotated 90.degree. about an axis along the horizontal direction during feeding from the first set to the second set of saws. The second set of saws slab two opposed sides of the log after 90.degree. rotation thereof, and a cant slabbed on four sides is thus formed. The distance between the pairs of saws of each set is adjustable by automatic detenting from one spacing to another, and the scrap is carried away from saw sets by conveyors outside of the saw sets.
