ABSTRACT:
Opposed parallel supporting rollers of a log receiving and turning assembly are rotated in order to rotate the log received thereon. The rollers are carried by a frame which is lifted or lowered, as desired, and a bar between the rollers is tiltable so as to lift selectively one end of the log or the other. By such an arrangement, the log is oriented so that a pair of dogs engage the log from opposite ends. These dogs are carried by an overhead carriage assemblies which ride on tracks and are movable with respect to each other by means of a hydraulic cylinder. One dog is rotatable by a motor through 90.degree. so as to orient the log. The carriage assemblies are movable in a longitudinal direction so that a pair of saws, driven by motors, will simultaneously cut the logs on opposite sides so as to deposit the boards, when cut from the log, on respective conveyors which carry the boards longitudinally away from the saws. The saws are adjustable laterally for different widths of log. The conveyors pivot for selective feeding to one or the other of parallel discharge conveyors. The cant is discharged by a central conveyor.
