Abstract
The glass sheets () of an asymmetric glass-sheet pair, which is intended for the production of laminated glass, are preheated in a preheating furnace () and then undergo a press-bending process in a press-bending station (). By means of a temperature measuring point () arranged at the exit of the press-bending station, it is ensured that the glass sheets exhibit a uniform bending behavior, in order to guarantee identical restoring forces during cooling. The temperature measuring point () is connected to a control device (), which causes an intermediate cooling of the glass sheet heating more rapidly by means of an intermediate cooling installation () in the pre-heating furnace and/or lengthens its dwell time in the press-bending station () by means of a timing control element ().
