調材面を剥削して製造されていた。Conventionally, artificial heathered decorative veneers are produced by laminating and press-depositing raw veneers with an adhesive between a pair of plates of a desired shape to form a flitch, and then applying the flitch to the adhesive layer to form the desired wood grain pattern. It was manufactured by preparing the material at a predetermined angle to the adhesive surface, and then scraping the prepared material surface with scissors.

し、積層することにある。However, when you want to make the grain width of the decorative veneer wider than the thickness of the raw veneer, as shown in Figure 1, the adhesive surface (2) of the raw veneer (1)
) (indicates the dot-dash line in the figure), but in this case, the effective value obtained as a decorative veneer with the desired wood grain pattern for the entire flitch The part (3) becomes narrower as shown in the figure, and the cut-off part (4) becomes a large space. In particular, if the raw material veneer is a processed veneer that has undergone treatments such as dyeing or bleaching, there will be a very large price loss, and the price of the effective part will rise accordingly. In view of the problems, the present invention has been completed. That is, in the present invention, a raw veneer is laminated and pressure bonded between a pair of templates of a desired shape using an adhesive to form a flitch, and then seven wrinkles are bonded so that the adhesive layer has a desired wood grain pattern. A method of manufacturing artificial heathered decorative veneer by preparing wood at a predetermined angle to the surface and then stripping the prepared surface, in which rough-quality veneer and good-quality veneer are joined at a predetermined ratio. After laminating the raw material veneers to make a flitch, coarse-quality veneers are located in the parts that are cut out in the preparation process, and good-quality veneers are located in the effective parts. Regarding the manufacturing method of artificial heathered decorative veneer, which is characterized by successive lamination of layers, one of its characteristics is that high-quality veneer is used only in the effective part that will become the decorative veneer. The process consists of constructing raw material veneers and laminating them.

Although not particularly limited, a method that does not use adhesive tape or thread is preferable.Next, a commonly used wood adhesive is applied to the surface of the raw material veneer and laminated between a pair of templates.◇At this time, the raw material veneer is laminated between a pair of templates. After turning into L flitch, the part that is cut off by preparing the material (4
) should be laminated in order so that the inferior quality veneer (5) is located in the effective part (3) and the good quality veneer (6) is located in the effective part (3). Next, the laminated veneers are pressed and bonded to form a 7-rich piece. Next, cut the 7-rich wood at a preset angle to the adhesive surface (2) and cut off the rough quality veneer (5) and a part of the sill (4) to reproduce the desired wood grain pattern on the prepared wood surface. Preparation of the material is preferably carried out using a commonly used circular saw or band saw.Next, the prepared 7-rich material is cut into a thin FIIJ using a cutting machine such as a slicer to obtain the desired artificial heathered veneer.

杢目化粧単板を提供することが出来る。The present invention uses the above-mentioned convenient method to produce artificially-grained veneers, so high-quality veneers can be effectively used, and unlike the conventional method, high-quality veneers are not wasted, and the raw material can be used alone. The yield and ratio of decorative veneer to board are also significantly improved, making it possible to provide artificial heathered decorative veneer at a reasonable price.

工杢目化粧単板を得がたいので実用的な方法ではない。Note that as a method similar to the method of the present invention, it is possible to laminate good quality veneers and rough quality veneers without joining them, but it requires a lot of effort to laminate the raw material male veneers and it is difficult to laminate the veneers. This is not a practical method because it is difficult to obtain a good artificial grained decorative veneer due to misalignment between the raw material veneers during pressing.

以下、実施例を記す。Examples will be described below.

I got rich. Next, remove the rough-quality veneer part in the 7 rich pieces to make a rectangular 7 rich piece, and then use a slicer to scrape the trimmed surface to a thickness of O, 4 wg to obtain the board grain. An artificial heathered decorative board with a pattern was manufactured with good yield.
