Abstract
A heated glass plate is bent by moving over a bed or rollers defining a path curved along the direction of movement of the glass plate so as to define an upwardly facing concavity. The glass plate moves with a speed of at least 10 cm/second and is curved by the bed without contact from above. The glass plate is subsequently tempered.
