Abstract
The invention relates to a method for bending glass sheets. A glass sheet supported by a ring mould (5) is caused to sag while being heated in successive heating stations. The glass sheet reaches a final bending temperature in a bending station (14). A press-bending mould (16) is transferred from outside bending station (14) into the bending station through an opening (22') in its wall. The ring mould (5) along with its glass sheet is lifted by means of a hoist mechanism (6) upwards for pressing the glass sheet against press-bending mould (16) for completing the bending. The same bending station (14) can also be used solely for gravitational bending when said press-bending mould (16) is retained outside the bending station.
