ABSTRACT:
The present invention provides a method of manufacturing high quality laminated veneer lumber from pre-flattened wood veneer, for such uses as in architecture and furniture, and a method of mass production thereof using veneer which is flattened in advance. A sheet of veneer is first obtained by cutting a log with a rotary lathe or the like, and flattening and cutting the veneer into a predetermined length. Sheets of veneer thus obtained are cut on both edges in the grain direction to form symmetrically diagonal end faces, and are bonded with one another at these end faces with their grain directions aligned to form an elongated sheet of veneer. The resultant elongated sheet veneer is cut into a predetermined length to form laminated veneer material having seams. Plural sheets thus formed laminated veneer material are laminated and bonded with their grain directions aligned to form laminated veneer core. The laminated veneer core is either directly used as a laminated veneer lumber, or is covered with another sheet of seamless veneer on an outer surface.
