[技術分野]
この発明は比較的低級な原木を利用して、より高級な銘
木単板を製造するための、いわゆる単板の集成技術の分
野に属する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention belongs to the field of so-called veneer assembly technology for producing high-grade precious wood veneers using relatively low-grade logs.
[背景技術]
単板の集成技術の分野においては、天然の銘木(1)
に少しでも近づけるために、原料単板の染色法を初めと
して種々の工夫が行われている。たとえば天然の松の木
目ないし外観に近似した集成単板の表現を行うために色
々な工夫が凝らされている。[Background Art] In the field of veneer lamination technology, various efforts have been made, including dyeing methods for raw veneers, in order to make them as close as possible to natural precious wood (1). For example, various efforts have been made to create a laminated veneer that approximates the grain and appearance of natural pine.
天然の松に外観上忠実な表現法として、松の春材色に染

を表現するために、単板表面に夏材色に着色されたシー
ト状物と原料単板を交互に、接着剤を介在させつつ積層
圧締してフリッチを造り、これを柾目方向にスライスし
て松様の外観を有する集成単板を得ていた。In order to express the appearance faithful to natural pine, the veneer is dyed in the springwood color of pine and has a thickness of 0.6 to 1.5, and the surface of the veneer is dyed to express the thick summerwood. A laminated veneer with a pine-like appearance is created by laminating and pressing sheets colored in the color of summer wood and raw veneers alternately with an adhesive interposed to create a flitch, and slicing this in the straight-grain direction. I was getting .
しかし、以上の方法で得た集成単板は、天然のものに比
べて単板物性が十分でなく、耐磨耗性なども十分でなか
った。また、2種類の異種の材料を使用しているため、
スライス時に目ぼれが発生する率も高かった。これは、
特に春材部表現に使用した染色単板自身の財物性が十分
でないことに・起因する。However, the laminated veneer obtained by the above method did not have sufficient physical properties and abrasion resistance compared to natural veneers. In addition, since two different types of materials are used,
The incidence of eye blurring during slicing was also high. this is,
In particular, this is due to the fact that the dyed veneer itself used to express the spring material is not of sufficient quality.
[発明の目的]
この発明は、以、ヒのような実情に鑑みてなされ(2)

技術を提供することを目的とする。[Purpose of the Invention] This invention was made in view of the actual situation as described in (2) below, and utilizes the manufacturing technology of laminated veneer to create a laminated veneer with physical properties similar to those of natural pine. The purpose is to provide a manufacturing technology for laminated veneers that can provide the following.

It is characterized by including a process of tightening and flitching. This will be explained in more detail below.

度の単板物性の均一な再生単板を得るのである。First, create recycled veneer. For this purpose, a colored adhesive with a coloring agent added between the dyed raw material veneers is used to create a color tone that reduces the conspicuousness of the laminated interface. This is to prevent the surface of the veneer from becoming darkened during dyeing, and when it is processed into laminated veneer, the adhesive interface becomes abnormally dark, reducing its fidelity to nature.) , the flitch is interposed between raw material veneers, and pressed and integrated between flat mold plates, and the obtained flitch is sliced in the straight grain direction (3). In this case, the thickness is preferably 0.3 to Q and 5 mm. Next, the sliced veneers are again laminated with the adhesive interposed therebetween and pressed in a flat plate to obtain a flitch, and the flitch is sliced in the straight grain direction. This operation is repeated twice or more any number of times, and finally the slices are sliced to a pre-designed thickness. In this way, a recycled veneer with high density and uniform veneer physical properties is obtained.

良などの効果がある。Conventional methods had the disadvantage that the raw veneer deteriorated during intermediate processes such as dyeing, which led to blurring during slicing and reduced product quality.However, recycling treatment improves the physical properties of the veneer. It is reinforced, reduces defects such as glazing, and has the effect of improving the yield of laminated veneers, improving physical properties, and reducing variations.

天然の松を表現するのである。The recycled veneer obtained as described above can be used as a sheet material of 100 to 300 μm colored in the color of summer wood, such as paper, non-woven fabric, etc.
Alternately with so-called resin vapor obtained by impregnating plastic sheets, paper or non-woven fabric with resin,
They are laminated with adhesive (4), flitched, and then sliced into straight-grained shapes to create the appearance of natural pine.

There are no particular restrictions on the raw material veneer l, but South Sea wood is usually used. Process this into a thin veneer using a rotary lace or the like. The raw material veneer 1 is then bleached and dyed as necessary. Next, they are laminated with the adhesive 2 interposed therebetween, and are sandwiched between flat mold plates 3 and pressed together. The adhesive used in this case is colored so that the adhesive interface between the raw material veneers 1 is not noticeable. The obtained primary intermediate flitch 4 is sliced in the straight grain direction. The obtained veneer is a primary recycled veneer 5.

In this case as well, a flat mold plate 3 is used. The veneer thus obtained is the second recycled (5) veneer 7. The number of repetitions of such pressing and slicing may be two or more times, and the number of repetitions is arbitrary. In this embodiment, the number of steps is limited to two. FIG. 3 shows the manufacturing process of the laminated veneer. The secondary recycled veneer 7 and the sheet-like material 8 obtained as described above are alternately laminated with an adhesive interposed therebetween, and pressed again with a flat plate mold to obtain a flitch 9.
