A log is moved forwardly in a longitudinal path through a saw while engaged between a pusher dog and a holdback dog. The dogs are supported respectively by a pair of endless carriers which are parallel and adjacent to each other on one side of the log path. The log is scanned and rotationally oriented before being engaged by simultaneous forward movement of the pusher dog and rearward movement of the holdback dog. Forward movement carries the log first to a chipper head and then to a guide surface which engages the face cut by the chipper head for stabilizing the log during sawing.

Logs are advanced through a saw while they are engaged between driven pusher dogs and retarded hold-back dogs. The pusher dogs are mounted on a lower endless roller chain below the logs, and the hold-back dogs are on an upper endless roller chain above the logs. The upper chain and its hold-back dogs are vertically movable to elevations dependent on the elevation of a log, thus assuring proper engagement. When the sawed portion of a log is retained laterally on a support, the hold-back dogs are moved forwardly away from the log so that a hold-back dog will be in the path of the next log to be handled by the system.

Logs are advanced substantially in the direction of their longitudinal axes through a saw while engaged between a driven pusher dog and a retarded holdback dog. The pusher dog is on an endless carrier chain located above an initial log support, and the holdback dog is on an endless carrier chain located below the log path and forwardly of the support. Logs on the support are movable angularly and laterally from the machine axis to displaced positions which are unobstructed by the carrier chains, to permit offset sawing and taper sawing. Chipper heads produce planar surfaces on logs approaching the saw. A retractible preliminary holdback dog engages the forward end of a log and moves past a bottom-flattening chipper head to a transfer area where the chain-carried holdback dog engages the log and the preliminary holdback dog is retracted.
