  • Patent number: 3977449
    Abstract: In producing a sheet of wood veneer having a large area and elaborate designed wooden patterns adaptable for mass-production and adaptable to be made with various wood patterns, a log is sawn or sliced into a plurality of individual flitches which are smoothened on the surfaces to be glued and subsequently glued by adhesive to form a composite flitch. The composite flitch is subsequently sliced to form a sheet of wide wood veneer which may be glued to a substrate or a veneer by adhesive. Throughout the process, all steps are carried out while the wood is maintained at a moisture content more than the fiber saturation point of the wood.

  • Patent number: 3977933
    Abstract: A process for producing veneer and fancy plywood therefrom having a combination of wood grain patterns and line patterns includes cutting out a symmetrical pattern piece from a section of wood and inserting the pattern piece into a hole in a section of wood in which the hole has a cross sectional configuration corresponding to the cross sectional shape of the pattern piece. The pattern piece is inserted into the hole in a position different from the original position and is subsequently secured therein utilizing an adhesive. Slices of veneer are cut from the section of wood such that the sliced veneer includes wood grain patterns of the pattern piece and the section of wood.

  • Patent number: 3969558
    Abstract: In producing a sheet of wood veneer having a large area adaptable for mass-production and adaptable to be made with various wood patterns, a log is divided into a plurality of individual flitches which are subsequently joined by adhesive to form a composite flitch. The composite flitch is subsequently sliced to form a sheet of wood veneer which may be joined to a substrate by adhesive. The sheet of veneer is formed while the wood is maintained with a moisture content more than the fiber saturation point of the wood.
