The glass sheets ( 2 ) of an asymmetric glass-sheet pair, which is intended for the production of laminated glass, are preheated in a preheating furnace ( 1 ) and then undergo a press-bending process in a press-bending station ( 4 ). By means of a temperature measuring point ( 11 ) arranged at the exit of the press-bending station, it is ensured that the glass sheets exhibit a uniform bending behaviour, in order to guarantee identical restoring forces during cooling. The temperature measuring point ( 11 ) is connected to a control device ( 16 ), which causes an intermediate cooling of the glass sheet heating more rapidly by means of an intermediate cooling installation ( 12, 13 ) in the pre-heating furnace and/or lengthens its dwell time in the press-bending station ( 4 ) by means of a timing control element ( 15 ).
