プラ啼シング処理するという方法が開発されている。A composite flitch is obtained by laminating and compression bonding multiple wood veneers using an adhesive, and this composite flitch is sliced in a direction intersecting the laminated surface, and the cut surface of the wood veneer and the adhesive are sliced. In the method of obtaining a nine-laminated decorative veneer by expressing the wood grain pattern with the cut surfaces of the layers, a gentle floating treatment is applied to the surface of the resulting veneer to form nine uneven surfaces along the wood grain pattern. In addition, a method was developed in which the surface of the laminated decorative veneer is treated with plastic by utilizing the difference in hardness between the wood veneer described above to express the spring wood portion and the adhesive described above to express the summer wood portion. ing.

が木目柄を不自然にする仁とが危い。In this embodiment, the surface of the dyed veneer 3 is textured to create a textured veneer 3' in a rounded manner that imparts a wavy width change to the summer wood portion of the wood grain pattern to be reproduced. However, this is not limited to this example, and can also be applied in the same way when noodles are made of untreated veneer 3.In this way, colorless or spring with low hardness is applied to the surface side of the dyed veneer 3 where the cracks appear. Apply adhesive 4 colored to the material color and seal the back crack! A plurality of dyed veneers 3 are laminated and pressed together using a summer wood-colored colored adhesive 4' which is coated on the surface of this back crack sealing layer and has a high hardness. The back cracking seal layer formed with the adhesive 4 of the summer material colored adhesive 4'
seepage into the back crack part, and the wood grain of the summer wood part 9m is reproduced as shown in Figure 2. The 1m5 surface side of the adhesive 4 (the side where the back crack is exposed) In addition, since the hardness is lower than that of the cracked seal layer, the summer wood coloring, and the packaging adhesive 4', it is difficult to brush the layer.
For K$P, ・Layer of summer material colored adhesive 4' and wear 6
Only the layer of colored adhesive 4' can be left as a convex part, and there is a danger that the existence of the back crack sealing layer may make the wood grain pattern unnatural.

に低減化できるなどの効果を有する。As described above, according to the manufacturing method of the decorative veneer of this first invention, a low-hardness colorless or spring wood-colored adhesive is applied and cured to the back cracking surface side of the spring wood veneer to seal the back crack. a crack-back sealing step for forming a layer, and formation of the crack-back seal layer;
Laminate and press-bond the plurality of wood veneers for spring wood with their faces aligned in a predetermined direction using a summer wood packaging adhesive that has a harder hardness than the colorless or round spring wood color adhesive. The method includes a step of forming a laminated frit to obtain a laminated 7-rich veneer, and a slicing step of slicing the laminated 7-rich in a predetermined direction intersecting the laminated surface thereof. It is possible to express sharp raised marks without soaking into the wood and blurring the reproduced wood grain pattern, and the slicing of nine laminated flitches can be performed smoothly.
This has the effect of reducing the
