Abstract
Abstract A method of manufacturing artificial wood veneers comprises a step in which an artificial flitch formed of laminated material veneers respectively cut out of a certain kind of inexpensive natural wood is sliced in the direction of obtaining straight grain pattern to obtain a collected veneer in which mutual joining surfaces of the material veneers extend in parallel with each other and in the thickness direction, and a step in which many of the collected veneers thus obtained and material veneers cut out of another kind of natural wood are laminated, pressed and collected to form another artificial flitch which is sliced in a direction of obtaining a flat or flowered grain pattern which is very similar to that of a high grade natural wood.
