あった。[Problems to be Solved by the Invention] However, a molded plywood is molded into a plywood having a three-dimensional curved surface, for example, a saddle-shaped plywood 7 as shown in FIGS. 10 and 11, or a spherical plywood 8. As a result, makeup tears 9, wrinkles 10, or makeup floats 11 that peel off a part of the makeup veneer often occur on the edge or surface of the makeup veneer, which impairs the appearance and reduces product retention. There was an inconvenience.
本発明は上記の事情に鑑みてなされたもので、三次元の
曲面を有する合板に成形しても、化粧単板に化粧破れ、
化粧浮き等が発生することのない成形合板の製造方法を
提供することを目的とする。The present invention has been made in view of the above circumstances, even when molded into a plywood having a three-dimensional curved surface, the makeup breaks into a decorative veneer,
It is an object of the present invention to provide a method for producing a molded plywood which does not cause makeup floating or the like.

することを解決手段とした。[Means for Solving the Problems] In the present invention, a decorative veneer and a core material are bonded together with an adhesive to form a flat surface material in advance, and then the surface material on the core material side. The core material and the backing material are sequentially arranged on the surface of the sheet through an adhesive, and the two pieces are sandwiched by a molding die composed of a male die and a female die having a three-dimensional curved surface from both sides, and heat and pressure are applied to simultaneously perform adhesion and molding. The solution was to form a plywood having a three-dimensional curved surface.
「作用」 本発明の方法は、化粧単板と添芯材とを予め平板状に一
体化しているので化粧浮きは皆無となる。"Operation" In the method of the present invention, since the decorative veneer and the spliner are integrated in a flat plate shape in advance, there is no makeup floating.
また、化粧単板は薄く、破れ易いが、丈夫な添芯材と一
体化されているのが、無理のかかる三次元曲面を有する
合板に成形しても化粧破れやしわが発生しない。Further, the decorative veneer is thin and easily torn, but since it is integrated with a durable core material, even if the veneer is molded into a plywood having an unreasonable three-dimensional curved surface, no cosmetic tear or wrinkle occurs.
「実施例」 第１図ないし第３図は、本発明に係る成形合板の製造方

し、三次元曲面を有する合板を成形する。In the method of the present invention, the decorative veneer 1 and the sprinkler material 2 are preliminarily adhered by heating and pressing with an adhesive,
A two-ply flat surface material 12 is molded. Then, a plurality of core single plates 3a and a backing material 4 are laminated on the surface side of the core material 2 of the surface material 12 with an adhesive agent interposed therebetween, and a male mold or a female mold having a three-dimensional curved surface is formed. It is sandwiched from both sides and heated and pressed to form a plywood having a three-dimensional curved surface.
上記成形合板は、三次元の曲面を有するため、成形時に
は、無理な力が加えられるが、化粧単板１は薄くて破れ
易いにもかかわらず、丈夫な添芯材２と一体化され、強
固な表面材12となっているので、化粧単板１に化粧破
れ、化粧浮き等が発生することがない。Since the molded plywood has a three-dimensional curved surface, an unreasonable force is applied during molding, but the decorative veneer 1 is thin and easy to tear, but is integrated with the durable core material 2 and is strong. Since the outer surface material 12 is formed, the makeup veneer 1 does not suffer from makeup breakage or makeup floating.
