1 is a side view. As shown in these figures, a three-dimensional male mold is used in which the substantially central portion 2 of the mold has a particularly raised convex shape. Of course, this male die is paired with a corresponding female die to form a 7-rich molding die.

。By the way, conventionally, when trying to obtain a flitch using the above-mentioned mold plate, most of the pressure was applied to the periphery of the mold, and no pressure was applied to the center of the mold, resulting in poor adhesion. Furthermore, even if an attempt was made to express isolated island heather in the center of the mold, a sufficiently faithful heather could not be obtained.

。The present invention uses veneers to be subjected to lamination pressing, the periphery of which has been compressed in advance, and an appropriate number of veneers with holes drilled in the areas corresponding to the island areas of the decorative veneer are sandwiched and laminated. It is characterized by tightening. This will be explained in detail below using cedar as an example.

が可能となったのである。In general, laminated cedar veneers are obtained by obtaining rotary veneers from raw wood logs using a rotaryless process, which is then bleached and then dyed.
The product is manufactured through the following steps: drying, color 1 transfer, lamination pressing (flitching), and slicing. However, due to this lamination pressing process, stress distribution occurs inside the flitch due to the shape of the mold, and in particular, even in a two-dimensional shape, a lack of pressure occurs in the center of the mold, which causes problems when slicing. This led to insufficient adhesion. Furthermore, in the case of an isolated island of cedar heather (3 in Fig. 2) as shown in Fig. 2, a lack of pressure is particularly likely to occur in that part. Therefore, in the present invention, the periphery of all raw material veneers is compressed and buckled in advance before use. This is shown by the shaded area in FIG. In addition, for ξ these veneers, for example, 1
A hole 5 is drilled in the center of every 0 sheets, that is, in a portion corresponding to an isolated island of the laminated decorative veneer. By making the flitch in this way, sufficient pressure was applied to the center, making it possible to obtain a flitch without any adhesion defects, and also to make it possible to express isolated cedar islands and heather.
