ている。2. Description of the Related Art Conventionally, long wooden veneers have been manufactured by connecting short veneers in consideration of the current situation where it is difficult to obtain long veneers of natural wood. And in this case, a long veneer is created by joining together a plurality of decolorized and dyed short veneers, and the plurality of long veneers are pressed and formed using an adhesive. In this way, a flitch is formed by blocking to form a flitch, and the flitch is sliced to produce a wood decorative board having a grain pattern on the surface. Here, when joining short short veneers together, connecting the short veneers so that the edges of the short veneers abut each other results in a low connection strength. An end portion of the plate is cut obliquely to form an inclined surface, and a long single plate is formed so that the inclined surfaces are bonded to each other.

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

As shown in FIG. 1, a short short veneer 1 obtained by slicing wood is first treated with a chemical, and then decolorized / decolorized.
The end of the dyed short short veneer 1 is cut obliquely to form the 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 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, and when the inclined surfaces 2 are combined, the upper surface and the lower surface of the adjacent short veneer 1 are formed to be substantially flush. Have been. Then, at the dyeing veneer stage, the resin is treated by impregnating with a water-soluble resin such as urea resin or melamine resin, and then dried. The slanted surfaces 2 are joined together with an adhesive to join a plurality of short veneers 1 together. The long single plate 3 is formed. Here, for example, in order to obtain a cypress-like veneer, a 20% water-soluble melamine resin is applied as a resin treatment under reduced pressure to a short veneer 1 having a thickness of 1.0 mm dyed in a cypress-like manner as a chemical treatment. Impregnation, followed by drying and moisture control at 100 ° C. for several minutes. Next, the central portion of the joining portion a of the long veneer 3 is cut out with a cutter or the like to cut out a part of the joining portion a. A thin plate 5 having the same thickness as the veneer 3 is arranged in the opening 4 and the thin plate 5 is fixed to the opening 4 by a colorless and transparent adhesive tape, and a plurality of long veneers 3 are bonded. The flitch 6 is formed by blocking with a molding die 7 by press molding through the agent. Next, the flitch 6 is sliced to produce a wooden decorative board A. The wooden decorative board A is adhered to a completely water-resistant plywood, painted and commercialized.

きるものである。The obtained wooden decorative board A can be of a long size which is difficult to obtain in nature, and the short veneers 1 are connected to form a long veneer 3. Although a long-sized product is manufactured by this, a part of the joining portion a is cut out and the thin plate material 5 is provided at the joining portion a. This prevents the line of the connecting portion a and the distortion of the grain from appearing clearly on the grain of the wood, thereby preventing a decrease in commercial value.

きるものである。As described above, according to the present invention, a plurality of short veneers are formed by diagonally cutting off the ends of the short decolorized and dyed short veneers to form inclined surfaces, and joining the inclined surfaces together. To create a long veneer, cut out a part of the connecting portion of the long veneer, embed a thin plate material that matches the shape of the hollowed out opening into the opening, and The board is blocked by pressing with an adhesive to form a flitch, and the flitch is sliced to produce a wood decorative board. There is no clear distortion of the wood,
It is possible to make the wood grain distortion and the line of the connecting portion less noticeable, and to prevent a reduction in commercial value.
