Abstract
A board positioning device selectively positions in a lateral direction in a generally horizontal plane a board translating in a longitudinal direction in the horizontal plane, wherein the board is aligned along its length in the lateral direction. The device includes a stepped fence, which may be selectively positionable, lying generally in the horizontal plane. A fence positioner cylinder may selectively position the stepped fence in the lateral direction in the horizontal plane so as to position one step of a plurality of steps on the fence to correspond to a desired transition path so as to position the end of the board at a board optimizing position as determined by an optimizer, whereby the board may be laterally, selectively positioned into an optimized position relative to trimmer saws located downstream from the stepped fence in the longitudinal direction when the board is urged laterally against the stepped fence by ending rolls.
