Abstract
Chipping heads are mounted for lateral movement in one dimension in a gang saw module which is itself moveable translationally in the first dimension and angularly in a second dimension, for skewing relative to an in-feed direction of a curved cant. The chipping heads are mounted on an in-feed side of the gang saw assembly. Stationary drive motors are mounted directly above the chipping heads, supported by a tower that is independent of the gang saw module. Vertical drive lines with U-joints drivingly connect the drive motors to the chipping heads while permitting the chipping heads to be moved normal to the axes of rotation of the drive motors. The motors are centered above the chipping heads, with their vertical drive axes midway between lateral endpoints in each dimension of the range of travel of the chipping heads. Motor spacing above the chipping heads and the drive line lengths are sufficient to accommodate that range of lateral travel. The chipping heads can move both with the saw module and laterally within it, independently of the stationary motors over an approximately oval area, to chip opposite sides of curved cants during in-feed for curve sawing.
