ABSTRACT:
An apparatus for bending and tempering glass plates has a horizontal roller furnace (3) and a press bending station with two water-cooled bending molds (6,7) through whose contact the glass plates are tempered immediately following bending. At the outlet from the roller furnace (3), the glass plates (1) are taken over by a continuous flexible conveyor belt (10) and are conveyed by the latter into the bending station. During the press process the glass plate remains on the conveyor belt, which is interposed between the glass plate (1) and the lower bending mold (7). The conveyor belt (10) is made from a woven or knitted fabric of heat-resistant metal fibers and, in a direction at right angles to its surface, has a heat resistivity of 0.25.times.10.sup.-3 to 5.times.10.sup.-3 m.sup.2 .times.K.times.W.sup.-1.
