Abstract: An in-feed conveyor brings individual pieces of lumber to an examining area, where a carriage is movably mounted relative to the conveyor for movement along the piece of stock. A control on the carriage is triggered whenever the carriage is positioned in predetermined alignment with defects in the stock, including undesirable end portions as well as structural or quality defects intermediate the ends of the piece. Triggering such control sends an input to a computer, which controls the cutting of the stock by a saw located downstream from the examining station, by which the defects are cut out of the piece of stock. The computer completely controls the incremental movement of the piece of stock at the saw, automatically stopping the stock and causing the same to be cut, not only to remove defects, but also to produce an optimum yield of different pieces cut from the good stock between the defects.

Abstract: Apparatus for easily and quickly cutting with mininum waste workpieces, such as components for making mitered corner picture frames, from an elongate strip of material of any predetermined width, in which each workpiece has opposing ends which are equally and oppositely angled with respect to each other and an inside edge of predetermined length, as follows. A guide device positions the elongate strip of material at desired positions along a longitudinally extending axis. A saw makes spaced, successive, angular, parallel cuts through the elongate strip to form workpieces with parallel angular cut ends and thereafter cuts off and removes a wastepiece from one end of each cut workpiece by making an oppositely angled cut.
