  • Patent number: 5698053
    Abstract: A plastic ply having at least one thermoplastic layer is positioned on a major surface of a glass ply to form a preliminary assembly, with the thermoplastic layer contacting selected portions of the major surface of the glass ply. A rigid press plate is placed on the plastic ply with the plate contacting a substantial portion of the plastic ply. Air is then removed from between the plastic and glass plies. After de-airing, the press plate is removed from the preliminary assembly and the preliminary assembly is subjected to elevated temperatures and pressures sufficient to intimately secure the plastic ply to the glass ply and form a laminate. If desired, the preliminary assembly and press plate may be heated to a temperature sufficient to soften the thermoplastic layer of the plastic ply while removing air from between the plastic and glass plies.
