  • Method of making curved insulating glazing panes
    Patent number: 5282911
    Abstract: For the manufacture of curved insulating glazing panes having close tolerances of form, surface and thickness, the curved single glass sheets (2; 22) are brought to their desired shape via rigid suction mold plates (1; 21) and are glued together in this condition. A device suitable for carrying out this method consists of a press having two rigid plates (3; 23), template strips (4, 5; 24, 25) and positioning stops (8, 10; 28, 30) corresponding to the theoretical shape of the glass sheets, and also retractable suckers (15; 26) disposed between the template strips (4, 5; 24, 25), being mounted on the rigid plates (3; 23).
