ABSTRACT:
A centerless rotary veneer lathe comprises a slidable backup device which is disposed on the opposite side of a peeler log from a knife carriage of the lathe. The backup device has a pair rotatable rolls located one above the other with the axes thereof extending in parallel to the axis of the log. The paired rolls are disposed such that the axes of such two rolls are spaced at substantially the same distance from an imaginary line extending perpendicularly to the axis of the log and in parallel to the direction in which the backup device is moved. In operation of the veneer lathe with the rolls set in contact with the log periphery, the knife carriage and the backup device are moved synchronously at such a variable controlled rate that causes peeling of veneer with a predetermined thickness.
