板となっていた。In the decorative board as described above, since hardwood is used as the surface veneer, a large number of large and small conduit grooves appear unevenly on the surface of the board, and the emulsion type emulsion is formed on the surface. Even if the adhesive is simply applied with one spreader roll, the inside of the conduit groove is hardly filled, and even if the adhesive is pushed into the conduit groove by the reverse coater, the adhesive is scraped off by the reverse roll. , When a thin decorative paper is pasted on it, the decorative paper is affected by the large conduit groove of the veneer and partly falls sharply, and the surface has large irregular irregularities and is unsightly. It was a veneer.
