LUMBER POSITIONING APPARATUS FOR END TRIMMING

摘要

An apparatus for positioning lumber pieces for end trimming, by means of a succession of gates mounted on traveling chains set at a converging angle wi th the even end line of uniformly spaced lumber pieces carried transversely on parallel chains towards a multiple saw trimmer. The positioning is accomplished by any one gate pushing against the end of a lumber piece and then retractin g when the lumber piece has reached the appropriate position for cutting by stationary trimming saws. The positioning process and the saw selection for each cut are scanner/computer controlled.
