METHOD OF GLASS BENDING SUPPORTED BY EXCESSIVE PRESSURE AND DEVICE SUITABLE FOR THIS PURPOSE

摘要

The invention relates to a device for bending at least one glass pane (I), at least comprising the following: - a lower bending mold (1) with a working surface (2) which is suitable for influencing the shape of at least one glass pane (I), and - an upper shaping tool (3) which is arranged opposite the working surface (2) and which is suitable for generating a positive pressure on the surface (O) of the at least one glass pane (I) facing away from the working surface (2). The upper shaping tool (3) has a cavity (5) with at least one opening (4) oriented towards the lower bending mold (1) and a membrane (6) which closes the opening (4), and the upper shaping tool is equipped with means for introducing a gas into the cavity (5) in order to deform of the membrane (6) in the direction of the lower bending mold (1) and thereby generate the positive pressure.
