ABSTRACT:
An apparatus for bending a glass sheet supported on a ring mould including a press-bending station provided with a plurality of thermally insulated walls, a press-bending tool assembly arranged above the glass sheet supported on a ring mould in the press-bending station, a claw crane mounted in the station for raising and lowering said press-bending tool assembly which includes first and second articulated arms connected to each other along a common axis of rotation. The first articulated arm has one end fixed to a ceiling in the press-bending station and an opposite end movable along the press-bending tool assembly. The second articulated arm has one end fixed to the press-bending tool assembly and an opposite end movable in a horizontal plane along the ceiling of the press-bending station. A power unit is located outside the station. A driving rod connects to the movable end of the second arm and is driven by the power unit through one of the walls such that the press-bending tool assembly is raised and lowered according to the horizontal movement of the movable end of the second articulated arm.
