Abstract

A method for laminating glass sheets wherein laminating film (1) is placed over one surface of a first glass sheet (2) and the film (1) is heated with short wave radiation (4) to a bonding temperature. Heated areas (8) of the film (1) are successively pressed to the glass sheet (2) in a continuous manner for purging air from between the film (1) and the first glass sheet (2) and for applying bonding pressure. The pressed film areas (8) are then cooled whereby an appropriate bond is attained between the film (1) and the first glass sheet (2). Thereafter the first glass sheet (2) with its bonded film is subjected to a partial vacuum and a second glass sheet (10) is positioned on the film (1) and the second glass sheet (10) is pressed (11) to the film (1). The film (1) is then reheated in selected areas with short wave radiation (12) to a bonding temperature and thereafter cooled whereby an appropriate bond is obtained between the selected film (1) areas and the second glass sheet (10) to provide a glass lamination.
