た。Conventionally, textured wood decorative boards have been produced using parallel veneers with the wood grain direction in the same direction as the ridgeline of the unevenness of the mold, in order to minimize warping and shrinkage of the molded board. It is formed by laminating orthogonal veneers that are oriented at right angles. However, with orthogonal veneers, the fiber direction of the wood grain acts in a way that increases the resistance in the bending direction, which not only increases the forming pressure but also tends to cause poor adhesion between the veneers due to springback. . For this reason, it was difficult to finish the surface smoothly, and it was difficult to express fine irregularities.

木質化粧板の製法をその要旨としている。以下に、これ
について実施例をあられす図面に基き詳細に説明する。This invention uses a mold with an uneven mold surface to press a laminate made by laminating orthogonal layers of veneer, parallel layers of veneer, and surface material via an adhesive. The gist of this method is a method for manufacturing an uneven wood decorative board, which is characterized in that the total thickness of the parallel veneers is greater than the maximum depth of the unevenness of the mold. Examples of this will be described in detail below with reference to the accompanying drawings.
この発明でいう平行層となる単板とは、金型の凹凸（波

するものをいう。In this invention, the veneer that forms parallel layers refers to one that has wood grain (fiber direction) in the same direction as the ridgeline direction of the unevenness (waveform) of the mold. In addition, the veneer serving as an orthogonal layer refers to one having a wood grain (fiber direction) that is perpendicular to the grain of the veneer serving as a parallel layer.

（繊維方向）が直交するように配置されている。FIG. 1 is a side view showing the uneven wood decorative board according to the present invention before molding. As shown in the figure, the veneer laminate 1 consists of veneers 3a and 3b arranged in parallel layers above and below the veneer 2, which is an orthogonal layer.
and a surface material 4 such as a decorative veneer placed on the top layer are laminated with an adhesive interposed therebetween. The veneers 2 serving as orthogonal layers and the veneers 3a, 3b, serving as parallel layers are arranged so that their grains (fiber directions) are orthogonal to each other.

It is molded. That is, the maximum depth of the unevenness of the upper and lower molds 5a and 5b as shown in FIG. 1 is H1+H, respectively.

The veneer laminate 1 is laminated so as to satisfy the relationships of >Hl, t, and >H2, and the veneer laminate 1 is subjected to a surface pressure of 10 to 15 kg/c, for example.

Since a..., 3b... are pressed together, it becomes almost unaffected by the resistance (reaction force) of the veneer 2, which is an orthogonal layer. FIG. 2 is a side view of the uneven wood decorative board thus obtained. As shown in the figure, the uneven wood decorative board 7 does not cause poor adhesion between the veneers.
The surface is smooth and beautifully finished.

ができるようになる。The method for manufacturing the uneven wood decorative board according to the present invention is to press a laminate made of orthogonal layers of veneers, parallel layers of veneers, and surface material using a mold with an uneven mold surface. When molding, the total thickness of the veneers forming the parallel layers is greater than the maximum depth of the unevenness of the mold. force). For this reason, relatively low pressure (10 to 15 kg/c
d) also allows molding and does not cause poor adhesion between the veneers. Therefore, the resulting uneven wood decorative board has a smooth and beautiful surface. Furthermore, even if the uneven shape is fine and complicated, it can be easily formed.
