この発明は、笹杢等の複雑な木目を人工的に造出する化
粧単板の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing decorative veneer that artificially creates a complex wood grain such as bamboo wood grain.
一般に銘木と呼ばれる木材は、木目が複雑に変化するも
のが多く、杉でいえば笹杢、浮材でいえばジャガランダ
のような木目が好まれる。In general, the wood that is called precious wood often has a complex grain pattern, and the preferred wood grains are those of Sasamotsu (Japanese cedar) and Jagaranda (Jagaranda).

て板面に板目柄等の木目模様をつくるものである。- On the other hand, there is a third method for artificially creating wood grain patterns.
A method of manufacturing a decorative veneer as shown in the figure is known. This method involves laminating a plurality of dyed or bleached material veneers 10 in a pair of molds 11 and 12 with an adhesive, bonding them by pressure to create an assembled flitch 13, and slicing this into a board. It creates a wood grain pattern such as a board pattern on the surface.

１６の形状を忠実に再現するのに対して、反対側の成形
型１５の凹部１７には単板１０が押し込まれないため、
空隙ができ、接着不良が生じていた。The molds 14 and 15 shown in FIG. 4 are composed of a mold having a convex portion 16 and a wooden mold having a concave portion that faithfully follows the convex portion 16. A material veneer 10 coated with adhesive is placed between these molds 14 and 15 as shown in FIG. 4(B).
Laminate and press and adhere. At this time, as shown in FIG. 4(C), the surface along the mold 14 having the convex portion 16 faithfully reproduces the shape of the convex portion 16, while the concave portion of the mold 15 on the opposite side Since the veneer 10 is not pushed into 17,
A void was formed and poor adhesion occurred.

う問題があった。In order to eliminate this problem, conventionally, high pressure was applied to force the material veneer into the recess 17, but this caused the stack of material veneers to shrink, and the material veneer was forced into the recess 17. There was a problem in that the number of decorative veneers to be removed was reduced.
この発明の目的は、接着不良がなく、しかも圧締による
歩減りの少ない化粧単板の製造方法を提供することであ
る。An object of the present invention is to provide a method for manufacturing a decorative veneer without defective adhesion and with less yield loss due to pressing.

着剤が硬化しない前段階では高い圧力で行ない、接着剤
が硬化する段階では低い圧力で行なうことを特徴とする
ものである。The method for manufacturing a decorative veneer of the present invention includes a pair of molds each having a convex portion and a concave portion corresponding to each other on the mold surface.
In a method for manufacturing a decorative veneer, in which a plurality of material veneers are laminated and pressure bonded via an adhesive to create a composite flitch, and the composite flitch is sliced, the adhesive does not cure the pressure bond. This method is characterized by applying high pressure in the preliminary stage and applying low pressure in the stage where the adhesive hardens.

る。As described above, according to the present invention, high pressure is applied to the laminate of material veneers before the adhesive hardens.
The material veneer is pushed into the recess provided in the - side mold,
Adhesion defects can be eliminated. In addition, in the subsequent adhesive curing stage, the adhesive is pressed at a low pressure, so it is possible to eliminate the large yield loss of products such as those caused by high-pressure molding.

じタイムチャートである。FIG. 1 is a time chart showing temporal changes in pressurization based on the method of the present invention, and FIG. 2 is the same time chart based on the conventional method.

段階において、ガス抜き終了後、高圧を加える。その後
、圧力を減らして従来とほぼ同じレベルに圧力を維持し
て接着剤の硬化反応を行わせる。That is, in the method of the present invention, high pressure is applied after degassing is completed in the initial stage when the adhesive is not yet cured. The pressure is then reduced and maintained at approximately the same level as before to allow the adhesive to undergo a curing reaction.
次に実施例および比較例をあげてこの発明の詳細な説明
する。Next, the present invention will be explained in detail with reference to Examples and Comparative Examples.

5m, Young's modulus 400 kg/afl, yield point 25kg
/cj, plasticity coefficient 80 kg/aJ), and 80 sheets were press-bonded. That is, as shown in Figure 1, after laminating the wood veneers, the inside of the mold was degassed, then a high pressure of 25 kg/eta was applied, and then the pressure was lowered during the adhesive curing stage to 15 kg/eta.
The adhesive was cured by pressing with g/c+Il.

The adhesion failure rate after slicing the flitch assembly was measured. The results are shown in the table below.
比較例１〜６： 成形時の圧締圧力を第２図に示すよう

ほかは実施例と同様にして成形、スライスした。Comparative Examples 1 to 6: Molding and slicing were carried out in the same manner as in Examples, except that the clamping pressure during molding was kept constant as shown in FIG. 2, and the number of molded pieces was reduced in Comparative Examples 5 and 6.
各比較例の成形条件および結果を次表に示す。The molding conditions and results of each comparative example are shown in the following table.
（以下余白）

がわかる。(Margins below) From Comparative Examples 1 to 4 in the table, it can be seen that when the clamping pressure is increased, the voids in the recesses of the mold are filled with the material veneer, reducing adhesion defects, but because it is made of wood, yield increases. As a result, it can be seen that the number of decorative veneers removed from one assembled flitch is reduced.
また、比較例５．６では１回の成形枚数を減らすことに
より比較的低圧力で成形型の凹部内の空隙が埋まり、接
着不良が減少していたが、生産性を低下させることにな
る。Furthermore, in Comparative Examples 5 and 6, by reducing the number of sheets molded at one time, the voids in the recesses of the mold were filled with a relatively low pressure, reducing adhesion defects, but this resulted in a decrease in productivity.
これに対して、実施例では歩減りを低下させずかつ接着
不良もほとんどなくすことができ、生産性を低下させる
ことがなかった。On the other hand, in the example, yield was not reduced and adhesion defects were almost completely eliminated, and productivity was not reduced.

製品の大きな歩減りをなくすことができる。According to this invention, high pressure is applied to the stack of material veneers before the adhesive hardens, so that the material veneers are pushed into the recesses provided in the - side mold, thereby eliminating adhesion defects. Can be done. Further, in the subsequent adhesive curing step, the adhesive is pressed at a low pressure, so it is possible to eliminate the large yield loss of products such as those caused by high-pressure molding.
