Abstract
In an apparatus for bending glass panes in a horizontal position, comprising an upper bending mold and a lower frame-shaped mold, the bending force exerted by the bending mold is determined by the self-weight of the bending mold. In order that a uniform pressure shall be exerted by the upper bending mold on the entire periphery of the lower frame-shaped mold, the upper bending is mounted displaceable on its guide rods relative to them in a vertical direction and variable in its angular position relative to the guide rods. To achieve the desired relief of weight of the bending mold, the guide rods are suspended by cables from a frame which can be lowered. On the frame, hydraulic or pneumatic cylinders are disposed, which each exert, via a pulling cable acting on a guide rod, an adjustable force in the opposite direction to the self-weight of the bending mold.
