Verfahren und Vorrichtung zum Biegen von Glasscheiben für laminiertes Glas.

摘要

Two glass plates placed on a deadweight type bending mold in an overlapping state are heated at a heating-pressing stage in a heating furnace to a temperature capable of bending glass and the side portions of the two overlapping glass plates are locally heated at a higher temperature so that the overlapping glass plates are bent along the shaping surfaces of an intermediate curved portion and deep-bending portions of said bending mold. The curved glass plates are subjected to a pressing operation by a pressing machine and thereafter, they are raised from the bending mold by means of raising rods which support the portion of the glass plates other than the peripheral portion to thereby quickly cool the deeply bent portion of the glass plates.
