Abstract

Glass plates are bent by discharging a glass plate from a suction plate onto a concave circumferential bending ring. Within the furnace (1) the glass plate is gripped by the suction plate (27) and is moved with the latter out of the furnace (1) into a combined bending and tempering station (10) and is discharged there onto the circumferential bending ring (19) located between two blowing boxes (11,13). Immediately following the discharge of the flass plate onto the circumferential bending ring (19), the suction plate (27) moves back to its starting position and the glass plate is tempered in this position.
