Description

【発明の詳細な説明】（技術分野）本発明は人工化粧単板の製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 artificially decorated veneers.

It has been a widely known and publicly used technique to form an artificial flitch and then slice the artificial flitch into thin pieces.

しかしながら上記従来の製法において一対の凹凸プレス

を有していた。However, in the conventional manufacturing method described above, when pressing a large number of wooden veneers with a pair of uneven presses, pressure is not applied uniformly to the wooden veneers, so when integrating them,
Although the adhesive can be sufficiently cured in the peripheral area by applying pressure, there is a problem in that the adhesive in the central area is insufficiently cured due to insufficient pressure, resulting in poor adhesion.

（発明の目的］本発明は上記従来の製法におけるかかる欠点を悉く解消

ものである。(Purpose of the Invention) The present invention aims to eliminate all of the drawbacks of the above-mentioned conventional manufacturing methods, provide the general society with a manufacturing method that applies pressure uniformly to the entire laminated wood veneer, and thereby contribute to the development of this industry. It is something.

（発明の構成）以下、本発明を実施例の図面に基いて詳細に説明する。(Structure of the invention) Hereinafter, the present invention will be explained in detail based on drawings of embodiments.

本発明は第１図に示すように両端の−厚みが、中央部よ

Create a composite veneer 13) as shown in the figure.Next, a large number of composite veneers 13) are laminated with adhesive interposed between them, and corresponding irregularities are formed on each one from the top and bottom. The inner surface is pressed with a pair of uneven presses 11111+ to form an uneven artificial flitch (5),
Next, the artificial flitch (5) is sliced to obtain an artificial decorative veneer (6) with a wood grain pattern.

When laminated composite veneers are pressed together vertically using a pair of convex and convex presses, the same pressure is applied to the entire composite veneer, eliminating the possibility of adhesion failure and preventing excessive pressure from being applied locally. Since there is no need to apply the flitch, there is no yield loss phenomenon, and the effect is that the artificial flitch can be formed extremely efficiently and with good productivity.
