Abstract: An apparatus and method for delivering pieces of lumber to a machining device having a longitudinal machining path and operating at a predetermined longitudinal speed. The infeed system comprises feed belt conveyors for carrying pieces of lumber simultaneously in directions both parallel with and perpendicular to the longitudinal machining path and a guide belt conveyor for receiving the pieces of lumber from the feed belt conveyors and moving the pieces of lumber substantially along the longitudinal machining path for receipt by the machining device. The speed of the guide conveyor is at least as great as the speed of the machining device. In addition, the placement of the lumber on the feed conveyor is preferably controlled such that individual pieces of lumber successively contact the guide conveyor. Accordingly, pieces of lumber do not overlap and any gaps between the individual pieces of lumber are minimized to promote efficient operation of the machining device and to minimize damage to the lumber.

Abstract: A method and associated apparatus for selecting a target rate of board treatment by a woodworking tool, measuring the difference between the actual rate of board treatment by the woodworking tool and the selected target rate, calculating the tool speed required to reduce the difference between the target rate and the actual rate to zero, and then periodically adjusting the tool speed of the woodworking tool based on the calculated speed required to reduce the difference to zero.
