ABSTRACT:
A method and apparatus for retractably supporting lumber cants above feed chains in a cant positioner-feeder for locating the cant in a position to optimize lumber yield. The cants are supported with retractable cant supports interpositioned between the feed chains. The retractable cant supports may be movably mounted so that longitudinal motion is imparted to the cant as the cant supports are retracted, thereby reducing the relative velocity between the cant and feed chains.
