ABSTRACT:
A process for the manufacture of veneer comprises gluing board-like, plane pieces of wood together with an adhesive to form a beam-like block of wood. The humidity content of the beam-like block of wood is increased. Veneer is cut from the beam-like block of wood and dried until the humidity content is below a fiber saturation point. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
