Patent number: 7476284Abstract: The invention relates to a method and apparatus for laminating glass articles without using an autoclave. The sandwich structure to be laminated is preheated than is placed in a controllable vacuum and subjected to electromagnetic radiation with specified frequencies and power. The final heating is provided by convectional heat source. Pressure that is applied continuously during the radiating, heating and cooling steps is also specified for achieving an appropriate bond. An apparatus appropriate for realizing the invented process is also provided. The apparatus includes a loading table, three furnaces, and a cooling chamber which are adjusted to and adjoined to each to other. These parts provide the necessary conditions for high-quality laminating simple and multi-sandwich structures with high production rate and efficiency. The apparatus is inexpensive and fits into the space of two glass article lengths.Type: GrantFiled: September 10, 2007Date of Patent: January 13, 2009Assignee: Gyrotron Technology, Inc.Inventors: Vladislav Sklyarevich, Mykhaylo Shevelev

Publication number: 20080292834Abstract: The present invention provides multiple layer glazing bilayers that utilize a masking layer over the polymer film component. The masking layer is specifically formulated to have a melting point that is less than the temperature employed in the autoclave process that is used to laminate the bilayer. The surprising result of the use of the specified masking layer of the present invention is a bilayer that can be processed according to conventional lamination methods but with a reduction in the damage and optical defects that normally occur during processing and installation of the bilayer product. After installation, the masking layer can be removed, exposing the previously protected, underlying polymer film.Type: ApplicationFiled: May 22, 2007Publication date: November 27, 2008Inventor: Steven Vincent Haldeman
