Abstract
Abstract A method of manufacturing a laminated body consisting of a synthetic resin member provided with a layer member thereon, in which the member is bent to cover the edges of the resin member. The method includes the compression, resulting from a male mold and a female mold approaching each other, of the layer member and molten resin. The female mold has flanges mounted on its edges to permit the layer member to cover the edges of the resin during compression. Molten resin materials are supplied between the male and female molds prior to subsequent to the compression.
