<p>Saw apparatus for cutting lumber along its length. The apparatus has a disk bed for supporting the lumber as the same moves during cutting, including multiple disks disposed in rows and spaced laterally from each other along the direction of travel of the lumber. The lumber is forced downwardly against the disks by pressure-applying instrumentalities, at a sufficient pressure to cause the disk edges slightly to penetrate the wood on the underside of the lumber without substantially exceeding the elastic limit of the wood. Cutting is performed while the forward travel of the lumber is so controlled. The pressure-applying instrumentalities are so adjusted as to permit the lead end of a lumber piece to pass therebeyond before coming down to produce the pressure. A method of cutting lumber along its length where the lumber is moved over a multiple-disk bed and the lumber is pressed downwardly against the disks in such bed with upper edges penetrating the wood in the lumber during the process of the cutting.</p> |
