Abstract

Discloses a positioning fence for use in lumber saw mills that facilitates automated positioning of lumber for cutting. A continuous moving track loop has a plurality of paddles laterally positionable across the width of the track. Each paddle has a brake to hold the paddle in position. A positioning cam releases the brake to align each successive paddle to a desired lateral offset and a zeroing cam resets each paddle to a zero position.
