ABSTRACT:
An improved apparatus and method for use in the rotary cutting of wood veneer is disclosed. The improved apparatus and method are preferably employed in connection with a conventional lathe having a pressure bar. Such a lathe is of the type that is used to produce wood veneer from a workpiece of wood, such as a log. The improvement is characterized as maintaining a preselected pressure of the pressure bar against the wood, and subsequently adjusting the preselected pressure bar position by using means for doing so, thereby producing wood veneer of uniform thickness and surface quality, independent of variations in wood density and wood hardness, such variations resulting from natural growth conditions and temperature of the wood.
