ABSTRACT:
A cooperative conveyor system for a lumber production line. The production line has a canting station and a sawing station spaced at a distance from each other and interconnected by a powered conveyor system. The cants are fed at a higher rate through the canting station than through the sawing station. The conveyor system is arranged to receive cants from the canting station at a high feed rate and transport the cants to and into a sawing station at a lower feed rate. The cants are fed through the canting station at controlled intervals so that the resulting gap between succeeding cants received on the conveyor are at a desired spacing to maximize the production of the sawing station. The cant exiting from the canting station is forced to overrun the conveyors feed rate and thereby reduces the gap between it and a preceding cant. The conveyor then transports the cant to and into the sawing station at the desired feed rate for the sawing station. In one embodiment, the sawing station has two saws. The conveyor system is arranged to shift the cant exiting the canting station into alignment with the saw selected to perform the sawing operation.
