Title: Method for manufacturing metal foil- or plastic film-overlaid laminate

Abstract: A method for manufacturing a metal foil- or plastic film-overlaid laminate which comprises completely covering a cleaned press plate with a cleaned metal foil, a cleaned plastic film or both of them in such a manner that the pressing surface of the press plate comes in intimate contact with the face side of said metal foil or plastic film, partially or completely sealing the resulting covering along at least two edges of the press plate, two of the edges being opposite to each other, applying the covered press plate to one or both sides of a laminating base, subjecting the resulting assembly to a laminating apparatus with heating under pressure, taking the assembly out of the laminating apparatus, and thereafter opening the covering to remove the press plate.
