METHOD AND APPARATUS FOR BENDING OVERLAPPING GLASS PLATES TO FORM A LAMINATED GLASS STRUCTURE |
摘要 |
Glass plates for a laminated glass are bent and strengthened by provisionally shaping by heating two overlapping glass plates placed on a deadweight bending mold having a shaping surface by elevating the temperature to a temperature capable of bending glass and by locally heating said portions of the two overlapping glass plates to be deeply bent at a higher temperature in a heating/pressing stage so that the two overlapping glass plates are provisionally shaped by their own deadweight into a shape substantially corresponding to the shape of the shaping surface of the bending mold, pressing a portion of the two overlapping glass plates to be deeply bent from the top by a pressing member after the provisional shaping step in a heating/pressing stage, separating the two overlapping glass plates from the bending mold by pushing up the portion of the glass plates other than the deeply bent peripheral portion of the two overlapping glass plates thereby cooling the peripheral portion of the glass plates in a peripheral portion strengthening stage, and cooling the overlapping glass plates to atmospheric temperature.
