ている。2. Description of the Related Art Conventionally, long wood veneer boards have been manufactured by connecting short wood veneers in consideration of the fact that it is difficult to obtain long wood veneers from natural wood. In this product, a plurality of short decolorized and dyed short veneers are joined together to create a long veneer, and the long veneers are pressure-molded with an adhesive. By forming blocks into flitches and slicing the flitches, a wooden decorative board having a grain pattern on the surface is manufactured. Here, when connecting short short veneers to each other, the connection strength becomes low if the edges of the short veneers are abutted against each other, so that the connection between the short veneers is short. A long veneer is formed by obliquely cutting the end portion of the plate to form an inclined surface and adhering the inclined surfaces to each other.

させるという問題があった。By the way, when the inclined planes 2 provided at the ends of the short veneer 1 are adhered to each other when forming the long veneer, as shown in FIG. Ideally, the front and back surfaces of the matching short veneers 1 are flush with each other, but as shown in FIG. 2 (b), the short veneers 1 may be vertically displaced from each other, or the short veneers 1 shown in FIG. In some cases, the thickness of the veneer is different as shown in (), and in such a case, a step is generated at the joining portion a. When the long veneer 3 having such a step is pressed on the mold, a partial thickness unevenness occurs and the wood grain is distorted, and at the same time, the cross-section of the joining portion appears to be enlarged. A part where the adhesive is accumulated is formed at the step of the joining part a, and the distorted grain of the grain and the line b of the joining part appear on the sliced plate material as shown in FIG. There was a problem of reducing the value.

着されて塗装が施されて製品化される。The present invention will be described below in detail based on the illustrated embodiments. As shown in FIG. 1, a short short veneer 1 obtained by slicing wood is first treated with chemicals to decolorize /
An end surface of the dyed short single veneer 1 is cut off obliquely to form an inclined surface 2. Here, the inclined surface 2 formed at the opposite end of the short veneer 1 to be joined is formed by cutting off the upper surface side of the end of one short veneer 1 and the other short veneer. 1 is formed by cutting off the lower surface side of the end portion of 1, and when each inclined surface 2 is combined, the upper surface and the lower surface of adjacent short veneers 1 are formed to be substantially flush with each other. Has been done. Then, at the stage of dyeing veneer, water-soluble resin such as urea resin or melamine resin is impregnated, treated with resin, and then dried, and the inclined planes 2 are joined together with an adhesive, and a plurality of short veneers 1 are joined together. A long veneer 3 is formed. Here, for example, when a cypress-like veneer is obtained, 20% water-soluble melamine resin is depressurized and added to the cypress-like dyed cypress-like short veneer 1 with a thickness of 1.0 mm as a resin treatment. It is impregnated with pressure, and then dried at 100 ° C. for several minutes and adjusted for moisture. Next, the central portion of the joining portion a of the long veneer 3 is hollowed out with a cutter such as a cutter to hollow out a part of the joining portion a to match the shape of the hollowed-out opening 4, and the thickness dimension is long. A thin plate material 5 formed to have the same thickness dimension as the single plate 3 is arranged in the opening 4, and the thin plate material 5 is fixed to the opening 4 with a colorless transparent adhesive tape to bond a plurality of long single plates 3 together. The flitch 6 is formed by forming a block by pressing with a molding die 7 through the agent. Next, the flitch 6 is sliced to manufacture the wooden decorative board A. The wooden decorative board A is attached to a completely water-resistant plywood, coated, and commercialized.

きるものである。The obtained wooden decorative board A can be made into a long size which is difficult to obtain in nature, and the short single boards 1 are joined to form the long single boards 3. Then, although a long size product is manufactured by this, a part of the joining portion a is cut out to provide the thin plate member 5 at the joining portion a. It is possible to prevent the product value from decreasing because the grain of the joint part a and the distortion of the grain of the grain do not become obvious.

However, the shape is not limited to this, and may have another shape, for example, the opening 4 and the thin plate member 5 may be formed in a tongue shape.
