Abstract
A pressure bar of the fixed type for veneer cutting is heated to reduce frictional drag against the wood surface. In the preferred form, the pressure bar is contoured having a tip with a relatively small radius of curvature and a face, in advance of the tip, which has a relatively large radius of curvature. The combination of a heated contoured pressure bar provides performance comparable with that of a roller bar in terms of roughness and friction, but at significantly reduced cost.
