ABSTRACT:
There is disclosed a machine for saw-sizing of lumber and a method for its use. The machine has a frame and a work table surface which supports at least one and, preferably four, bandsaws. The bandsaws are each positioned at an incident angle from 20.degree. to about 80.degree. to the surface of the lumber which is fed through the machine. The lumber is fed from the back side or back edge of the bandsaw saw blades. The machine is specifically designed for a single pass sizing of all four sides of lumber with two vertical bandsaws and two horizontal bandsaws; the horizontal bandsaws are positioned to size the bottom and top surfaces of the lumber while the vertical bandsaws are positioned to size the opposite vertical sides of the lumber. The method comprises passing the lumber through the machine from the back edge of the bandsaw blades to drag the lumber against the bandsaw blades. This results in a rough saw sized texture to the lumber without any significant change in its dimensions.
