As shown in Fig. 1, a thin striped pattern 2 is expressed in addition to the summer wood part 1 on the natural rose wood or teak wood veneer. In the conventional manufacturing method of artificial decorative veneer to express a wood grain pattern similar to rose wood or teak wood, one-colored adhesive is used as shown in Figure 2 (a) Nagomi Shige). The veneer 3 is laminated with adhesive (see figure (a)), flat type (not shown)
A primary assembled flitch 4 was obtained by pressing and bonding with
After slicing this 7-rich veneer 4 slightly diagonally to obtain a sliced veneer 6 with a colored portion 5 formed on the board surface (see Figure (C1)), the sliced veneer 6 was laminated with an adhesive. Then, a secondary assembled flitch 8 was obtained by pressing and bonding with a concave-convex die 7 (see the same figures (dl and (el)) (however, the flitch 8 in the same figure (el) shows the one after sawing). A method is adopted in which a decorative veneer 9 having a wood grain pattern as shown in the same figure (fl) is manufactured by slicing.

According to this method, as shown in FIG. 2(f), the decorative veneer 9 finally obtained is colored with the adhesive used in forming the secondary laminated flitch in a summer material color in advance. The wood part 1' is formed, and the striped pattern 2' is formed by the colored adhesive used in forming the flitch, but the striped pattern 2' becomes thicker and less sharp, and cannot be used depending on the tree species to be expressed. There was a problem.

また、前述のように圧締接着操作を二度行なわなければ

The first embodiment of the present invention will be explained based on FIG. , veneer 1
A patching material 1 made of the same material as the veneer 10 is formed in the punched holes 11 at several locations of the veneer 10.
2 (same figure (al)), then laminated with an adhesive colored in summer wood color, and pressed and bonded with the uneven mold 13 to obtain a flitch assembly 114t (slice the flitch assembly 14 in the same figure (in BL)). Thus, a decorative veneer 17 on which a striped pattern 16 is formed in addition to the summer wood portion 15 is obtained.

In this way, in this embodiment, the striped pattern 16 of the decorative veneer 17
Since this is expressed by the fitting part between the punched hole 11 and the patching material 12, a relatively sharp striped pattern can be obtained, and the pressure bonding to form the assembled flitch only needs to be done once. , production efficiency can be improved.

Note that if the outer periphery of the patching material 12 is colored in advance, the color of the stripes can be changed freely, and if necessary, the materials and colors of the patching material 12 and the veneer 10 may be changed. Further, it goes without saying that a cutout hole may be formed in place of the punched hole 11.

Conventionally, plywood has been manufactured by laminating and bonding dried veneers (below air-dried) onto the plywood with vinyl acetate-based adhesives or original adhesives along the side edges. Defects in IIU veneer (tar, knots, etc.)
The repair is carried out by placing a veneer 100 having a defective part 18 on a die 19, punching out the defective part 18 with a punch 20 and removing it, as shown in FIGS. Board 10
A repair veneer 21 of the same shape was fitted into the punched hole 101 of No. 0. However, unless a highly accurate and expensive die is used for punching, there is a problem in that a gap A as shown in FIG. 5 is created between the veneer 100 and the repair veneer 21 ( A similar problem occurs with cropping). Furthermore, (5) it is difficult to press-fit the repair veneer 21, and the repair veneer 21 often sticks to the application roll (not shown) when applying the adhesive. In order to eliminate these defects, it is necessary to sew or tape the parts. Furthermore, plywood with visible gaps, repaired areas, seams, tape, etc. is not suitable for applications where pattern expression is important.

Therefore, in this embodiment, as shown in FIG.
.. A pear-shaped cut hole 11' (cut) of 4 to 0.5 strips of wood is made (see figure (al)), and then a 0.1 to 0.2 rran thick cut is made on the veneer 10" with adhesive. The non-woven fabric 24 is pressed and bonded, and the non-woven fabric 24 is inserted into the hole 11' as a patching material (see FIGS. After coating (Figure (dl)), they are laminated and bonded by pressure to obtain a flitch, and this flitch is sliced to express a radiation structure 26 on the board surface as shown in Figure (C).

With this configuration, the radiation structure of the nine single plates obtained is 26.
There are different tissues 26 in the center as shown in Figure 9 (el K).
It has a very natural feel to it. Therefore, it is possible to freely express each radiation structure of the medium-grain square and coarse-grain square 9-plate grains, and it is possible to express subtle color changes between the center and the outside. The rest is the same as the first embodiment.
