Abstract
An improved timber thicknessing machine comprises a support frame, at least two parallel, continuous drive chains, a multiplicity of slats disposed in spaced parallel positions extending between the drive chains to form a continuous belt, a rotary cutter block disposed above the belt generally parallel to the slats and having cutter blades around its circumference, rollers above the belt on each side of the cutter block to cooperate with the belt in advancing a workpiece through the machine, and pressure bars resiliently mounted above the belt between the respective rollers and the cutter block to urge the workpiece towards the belt.
