The glass sheets (1,2) are placed in a ring (7a) that is on a movable bending ring holder (3), and ring holder is moved to a furnace. The glass sheet is heated to softening temperature and is pre-bent to 5-50% of edge final bend. The glass sheet is raised by a suction device (5) and bent by ring. The minimum distance is maintained between the glass sheet and an air baffle in suction device. The glass sheet is placed in a bending ring (7b) and bent by heat radiation. The glass sheet is raised from bending ring (7b) and pressed in a counter-mold (16), and then cooled. An independent claim is included for device for bending glass sheet.
