Abstract
The present invention provides the method of manufacturing the artificially figured veneer or artificially figured board at high productivity with the expression of the grain and figure of natural wood in very similar form observed in natural woods, in addition to normal grain of natural wood. The present invention relates to the method of manufacturing an artificially figured veneer or an artificially figured board, comprising the steps of 1) preparing a set of a multiple sheets of material veneers by rotary cutting a log or repeatedly cutting a wood flitch with their grains sequential, 2) embossing simultaneously said material veneers whose number was determined according to the static bending strength (proportional limit) and specific gravity of the material veneers, with press dies having concave-convex patterns corresponding to a site of figure of a natural wood, to form a concave-convex pattern on the material veneers, 3) laminating the set of embossed material veneers such that their grains become substantially sequential, and pressing it with said press dies, and 4) cutting the laminate in the direction crossing the plane of the lamination to manufacture an artificially figured veneer or an artificially figured board with desired thickness.
