ABSTRACT:
A woodworking machine to form finished dimensional lumber from cants by a single pass of the cants through the machine and comprising compression and feed rollers above and below a longitudinal path and parallel longitudinally offset arbors respectively are mounted above and below the path upon which spaced saw blades are mounted with opposed blades in common planes and of diameters adequate to form complete cuts through a cant during a single pass, the arbors also supporting between the blades additional cutters to plane the edges of the dimensional lumber and form rounded edges thereon. The blades comprise combination saw and planer blades in which a disc has evenly spaced notches forming fingers each having a straight edge upon which tapered carbide cutting strips are mounted, the wider ends being innermost and the opposite sides of the narrower ends being rounded to permit the opposite edges of the strips to serve as planing blades capable of producing smooth faces on the lumber free of markings or ridges while the additional cutters form planed edges between the opposite faces and rounded edges at all corners of the lumber.
