Abstract
Press-bending station for bending sheets of glass during the course of automated production of identical motor vehicle windows within specified batch sizes, where the glass sheets to be bent are heated in a continuous furnace to a specified bending temperature and directly after leaving the continuous furnace are fed in horizontal position with the aid of a horizontal conveyor into the press-bending station. It incorporates a male press mold and a female press mold. The male press mold is a cast full mold and consists of an aluminum alloy. The male press mold possesses heating passages for fluid heating with the aid of a liquid heat transfer medium and can be heated with sufficiently homogeneous temperature distribution to a thermal expansion temperature which is below the bending temperature. The temperature of the male press mold can be controlled and/or regulated by means of the liquid heat transfer medium. The thermal expansion temperature of the male press mold is controlled and/or regulated such that the specific thermal expansion of the male press mold and the thermal expansion of the glass sheet to be bent, placed centrally on the female press mold at bending temperature, practically correspond.
