System to produce wood products from peeler core logs

Claim 1

A saw and chipping device to convert veneer peeler core logs into useful boards of a dimension to produce maximum useful products and minimum waste comprising in combination, a pair of parallel arbors and power means to rotate the same in opposite directions, said arbors respectively being above and below a longitudinal path along which said logs travel, similar sets of alternate saws and chippers keyed respectively to said arbors, the diameters of said saws being selected to cut slightly more than half the diameter of said logs and one set trailing the other a predetermined distance and similar saws of said sets being in common planes perpendicular to said arbors, whereby said sets of saws cooperate to make complete cuts through said logs, and said sets of saws having said chippers therebetween which progressively increase in diameter respectively from the mid portion of each set of blades toward the opposite ends of said sets and the tips of said chippers being shaped to produce desired finished opposite edges on the assembly of boards sawed simultaneously by said saws of maximum varying widths according to the section of the logs sawed by said saws and the shape of said boards being selected by the number of saws and diameter of chippers to maximize useful boards and minimize edge waste, feed rollers upstream from said sets of saws and chippers to guide peeler logs to and through said sets of saws and chippers, and at least one pair of auxiliary guide rollers downstream from said saws and chippers and comparable in width to the same and respectively above and below the sawed boards and provided with circular surfaces increasing in diameter from the center toward the opposite ends and substantially complementary to the opposite edges of the sawed board assemblies to support and guide the same in discharging direction from said saws and chippers.
