CONT: Each layer of plywood is called a veneer; these are produced in several ways including rotary cutting, half-round cutting with the stay log, slicing, and sawing. Rotary cutting is by far the most important ... Logs which are to be made into rotary-cut veneer ... are removed from storage and cut into bolts ... The bolts are softened ... and the bark is removed. Each bolt is centered in a large lathe, and the cutting mechanism - a pressure bar and knife that run the full length of the bolt - is put in place. As the bolt is turned, the knife peels off a thin layer of veneer while the pressure bar compresses the wood ahead of the knife to reduce splitting and cutting checks.
CONT: Peeling provides the greatest volume and the most rapid production, because logs are merely rotated against a flat knife and the veneer is peeled off in a long continuous sheet.
