この発明は、天然杉の笹杢柄に近似した柄表現が可能な
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 producing a decorative veneer that is capable of expressing a pattern similar to that of natural cedar.
従来より、天然木の木目模様を人工的に表現するために
、狙いとする樹種の春材部色に着色した素材単板と夏材

チを所定方向からスライスして板面に木目模様を形成す
る化粧単板の製造方法がよく知られている。Conventionally, in order to artificially express the grain pattern of natural wood, we have used a material veneer colored in the spring wood color of the target tree species and a summer wood forming material such as non-woven fabric colored in the summer wood color. A composite material is created by pasting together, multiple sheets of this composite material are laminated with an adhesive and pressed together to form a composite flitch, and this flitch is sliced in a predetermined direction to create a wood grain pattern on the board surface. Methods for producing decorative veneers are well known.
ところで、天然杉の笹杢柄は、第４図に示すように、木
目間の間隔Ａがつまっており（木目間隔は通常１〜２ａ
１程度）、かつ鋸歯状を呈している。By the way, as shown in Figure 4, in the bamboo pattern of natural cedar, the spacing A between the grains is narrow (the grain spacing is usually 1 to 2 a).
1) and has a serrated shape.
したがって、かかる笹杢柄を人工的に表現するためには
、できるだけ厚さの薄い素材単板、好ましくは厚さ０．
６１■以下の木質薄板を使用し、かっこの木質ａ仮に不
織布等の夏材部形成素材を貼着した複合材にエンボス加
工を施す必要がある。Therefore, in order to artificially express such a bamboo heather pattern, it is necessary to use a veneer of material as thin as possible, preferably with a thickness of 0.
It is necessary to use a wooden thin board of 61cm or less and emboss the composite material to which a summer material such as a non-woven fabric is attached.
しかしながら、このような厚さの薄い素材単板を用いる
場合、接着剤の塗布時に素材単板がロールコータに巻き
ついてしまったり、接着不良が生じるなどのトラブルが
多く、生産性がわるかった。However, when such a thin material veneer is used, there are many problems such as the material veneer wrapping around the roll coater during adhesive application, and poor adhesion, which reduces productivity.
この発明の目的は、笹杢柄等の間隔のつまった木目柄を
簡単に表現することができ、しかも高い生産性を存する
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 that can easily express a closely spaced wood grain pattern such as a bamboo grain pattern and has high productivity.
この発明の化粧単板の製造方法は、厚さの薄い春材部色

するものである。The method for producing a decorative veneer of the present invention involves applying a low-viscosity adhesive to the upper surface of a first thin wood board having a thin spring wood color, and then forming a summer wood portion having liquid permeability on the upper surface. A composite material is created by laminating the material, a liquid-permeable second wood thin plate in the color of the spring material, and the material forming the summer material in this order and bonding them by pressure, and then pressing the plurality of sheets together with an adhesive. This method is characterized by forming a flitch assembly by tightening and slicing the flitch assembly.
このように、この発明によれば、使用する接着剤は低粘

ことができる。As described above, according to the present invention, since the adhesive used has a low viscosity, even if this adhesive is applied to the first thin wood board using a roll coater, the thin wood board will not wrap around the roll coater. Therefore, it is possible to easily create a bamboo grass pattern with dense wood grains using a thin wooden film that could not be coated with a roll coater in the past.
また、低粘度の接着剤を塗布した第１の木６３板の上面

では一挙に４層の複合材を１回の接着剤塗布で簡単に作
成することができ、生産性が向上する。In addition, on the upper surface of the first wooden 63 board coated with a low-viscosity adhesive, a material for forming a summer wood part that is compatible with liquid i3, a second thin wooden board that also has liquid permeability, and a material for forming a summer wood part are laminated. Since the pressure is applied, the adhesive applied on the first thin wooden board permeates through the summer material forming material and the second thin wooden board, so that these can be adhered to the body. Therefore, whereas conventionally a two-layer composite material was created by pasting one summer material forming material onto a single thin wooden board, in this invention four layers of composite material were created at once. It can be easily created with just one application of adhesive, improving productivity.

The figure (C) shows the composite material 3 that has been embossed.

．７を配置して平型８で圧締接着する。The first wood GM board 1 is selected from a large number of thin wood boards (thickness 0.2 to 0.5 tm) that have been dyed in the spring wood color in advance, with a thickness of about 0.4 to 0.5 tm. It is something that The first tree 1 is placed on the top surface of the thin plate 1 in FIG. 1 (A).
Adhesive 2 is applied using a roll coater 4 as shown in FIG. This adhesive 2 has a viscosity lowered to 600 to 1000 cP. Then, as shown in Figure CB), adhesive 2
Summer wood portion forming material 5 is applied to the upper surface of the first thin wooden board 1 coated with
, the second thin wood board 6 and the summer material forming material 5 are laminated in this order, and a release sheet 7 is further applied on both sides of the laminated IW.

し確実に接着することができる。As the summer material forming material 5, a material such as a nonwoven fabric having liquid permeability can be suitably used, and if the summer material forming material 5 does not have liquid permeability, it can be coated on the first thin wooden board 1. The adhesive 2 made it impossible to bond the first thin wood board 1 and the second thin wood board 6 via the summer material forming material 5. The second thin wood board 6 is thinner than the first thin wood board 1, and has a thickness of about 0.2 to 0.3 among the thin wood boards dyed in the spring wood color. tm and use it. With this extremely thin 11m wood board, it is impossible to apply adhesive using the normal coating method using a roll coater because the thin wood board wraps around the roll coater. Since the thin plate has liquid permeability, the adhesive permeates through the thin plate during pressure bonding, allowing reliable bonding.

Therefore, the thickness of the first thin wood board is approximately 0.4
~0.50, the viscosity of the adhesive is 6 from Figure 2.
It can be seen that by adjusting it within the range of 00 to 1000 cP, it is possible to prevent winding around the Habo roll coater. This improves productivity for obtaining decorative veneers.

This laminated flitch 10 is sawed and sliced from the direction intersecting the laminated surface as shown in FIG. 3(B) to obtain a serrated wood grain pattern as shown in FIG. A decorative veneer 12 is obtained.

The composite materials were laminated and bonded under pressure of 15 kg/am'' to obtain a composite material.

Sliced from. As a result, we were able to obtain a decorative veneer that expressed a sawtooth-like bamboo grain pattern on the board surface with tight spaces between grains. This bamboo heather pattern had an extremely natural feel.

Therefore, it is possible to easily create a bamboo-grained pattern etc. using a thin wooden board that could not be coated with a roll coater in the past.

As the adhesive is tightened, the adhesive applied on the first thin wooden board passes through the summer material forming material and the second thin wooden board at t3, so that these can be bonded to the body. Therefore, whereas conventionally a two-layer composite material was created by pasting one summer material forming material to one thin wooden board, in this invention, 411 composite materials were created at once. It can be easily created by applying adhesive, improving productivity.
