本発明は人工木目化粧単板の製造方法に関し、
詳しくは複雑でより自然な人工木目柄化粧単板を
歩留り良く製造する方法に係わる。[Detailed description of the invention] The present invention relates to a method for manufacturing artificial wood grain decorative veneer,
More specifically, the present invention relates to a method for manufacturing decorative veneer with a complex and more natural artificial wood grain pattern at a high yield.
従来の人工木目化粧単板は所望形状の型板間に
有色又は無色の接着剤を介して木目柄がないか、

び調材剥削して製造されていた。 Conventional artificial wood grain decorative veneers do not have a wood grain pattern by using colored or colorless adhesive between the templates of the desired shape.
It is manufactured by dyeing or undying the almost invisible raw material veneer, pressing and laminating it to form a fritchi with the desired shape, adjusting the material so that the adhesive layer has a wood grain pattern, and then peeling it off. Alternatively, in order to obtain a more natural, delicate, and complex pattern, the decorative veneer obtained by preparing and peeling the wood is laminated again between templates of the desired shape using colored or colorless adhesive. It was manufactured by gluing it together and scraping the material again.

結果となる。 However, if the adhesion-preparation-striping process is repeated, the curved surface of the fritches is removed in the material preparation process and then peeled off using a slicer, so the raw material veneer that makes up this curved surface is wasted, resulting in This results in a decrease in retention and an increase in the cost of decorative veneer as a final product.
本発明は上記のより自然で繊細、複雑な柄を歩

る点に有る。 The feature of the method of the present invention is that the artificial wood grain decorative veneer manufactured by the conventional method is again pressed and laminated between the desired templates using a colored or colorless adhesive.
The purpose is to minimize the loss of commercially valuable veneers by considering the order in which the veneers are laminated when making a laminated flitch.

る。 As described above, according to the method of the present invention, the frit parts removed in the first and second preparation processes are laminated in such a way that they become cheap raw material veneers with reduced commercial value. Not only will raw material veneers not be wasted, but secondary decorative veneers containing cheap raw material veneers with reduced commercial value can be almost completely prevented from occurring by changing the stacking order of primary decorative veneers. This has the effect of greatly improving the yield of the final product, the secondary decorative veneer.
以下本発明の実施例を記す。 Examples of the present invention will be described below.

剥削して0.6mmの第一次化粧単板を得た。Example 1 A white meranti veneer with a thickness of 0.8 mm was dyed reddish-purple and used as a raw material veneer. Next, 500 of the veneers were laminated between a pair of curved templates with complementary unevenness of 50 mm using a urethane adhesive colored blackish brown. During lamination, 55 1mm-thick Agatis veneers, whose commercial value has decreased due to blue contamination, were laminated with adhesive on the top and bottom of the veneer, and pressed together at a pressure of 20 kg/cm 2 for 10 hours. , a first-order laminated fritsch.
Next, the laminated fritches were prepared to make the desired primary grain pattern appear on the fritted surface, and then that surface was scraped to obtain a 0.6 mm primary decorative veneer.
