角部が得られない欠点があつた。DETAILED DESCRIPTION OF THE INVENTION Conventionally, a sheet pasted with a precious wood veneer having a thickness of about 0.2 mm has been known, in which a precious wood veneer with a thickness of about 0.2 mm is adhered to a sheet-like material such as paper or cloth via an adhesive. However, when this precious wood veneer sheet was attached to a substrate with a small radius of curvature at or near right angles, there was a drawback that the veneer especially around the conduit part cracked and swelled, making it difficult to attach it neatly. Furthermore, if the veneer is thick, the effect of twisting of the veneer cannot be ignored, resulting in poor workability. In order to prevent this twisting, etc., the thickness of the backing material sheet was increased, but this had the disadvantage that sharp corners could not be obtained when the precious wood veneer sheet was applied to the substrate.
この発明は上述した欠点を解消したものであつ
て、すなわち、シート状物に接着剤を介して銘木
単板を接着した後、単板表面を研削して単板の厚
みを0.2mm未満にすることを特徴とする曲げ加工
の容易な銘木単板貼りシートの製造方法に係る。 This invention solves the above-mentioned drawbacks, namely, after bonding a precious wood veneer to a sheet-like object with an adhesive, the surface of the veneer is ground to reduce the thickness of the veneer to less than 0.2 mm. The present invention relates to a method for manufacturing a precious wood veneer sheet that can be easily bent.

れたとしても取扱いが大変なためと、薄くするこ
とによつて単板の可撓性を増させるためである。
なお、最も好ましい単板の厚みは0.05〜0.15mmで
ある。 In this invention, the sheet-like material refers to a sheet of paper, nonwoven fabric, woven fabric, rubber, plastic, or the like. In addition, after gluing a precious wood veneer to a sheet-like object, it can be ground to less than 0.2mm using a slicer.
This is because it is difficult to obtain precious wood veneer with a thickness of less than 100 ml, and even if it is obtained, it is difficult to handle, and by making it thinner, the flexibility of the veneer can be increased.
Note that the most preferable thickness of the veneer is 0.05 to 0.15 mm.
この発明は上述したように構成されているの
で、単板の本来もつねじれやそりの影響の少ない
作業性にすぐれた銘木単板貼りシートを得ること
ができる。 Since the present invention is configured as described above, it is possible to obtain a sheet pasted with precious wood veneers that has excellent workability and is less affected by twisting and warping inherent in veneers.

The surface of the veneer was ground with abrasive paper to give a thickness of 0.14 mm.

着できた。 When this Sapele veneer sheet was adhered to a plastic molded product with a radius of curvature of 4 mm, cracks occurred with the veneer thickness of 0.28 mm, but when the veneer thickness was
No cracks occurred with the 0.14 mm one. Additionally, a veneer with a thickness of 0.14 mm could be bonded to a plastic molded product with a radius of curvature of 1 mm without cracking.

It was glued at. This was ground using an electric planer until the thickness of the veneer was 0.20 mm. The surface of this oak veneer sheet is finished with urethane coating,
When bonded to curved plywood, the veneer with a thickness of 0.35 mm had a radius of curvature of 7 mm and cracks occurred around the conduit, but the veneer with a thickness of 0.20 mm did not crack even with a radius of curvature of 2 mm. Ta.
