<p>SAWMILL APPARATUS 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.</p> |
