  • Patent number: 5441551
    Abstract: A device for pressing and bending glass panes comprises an upper, solid-faced bending mold and a lower frame-shaped mold. The lower frame mold is mounted horizontally traversable and serves at the same time as a support ring for transferring the bent glass pane into a cooling station. The frame-shaped mold is provided with an electrical heating resistor. In addition, a temperature sensor is disposed in the frame-shaped mold. The temperature of the frame-shaped mold can be regulated to a predetermined temperature by way of a power regulator, which is governed by the temperature sensor.

  • Patent number: 5330550
    Abstract: An installation for the bending of glazings (6) includes a continuous furnace (1), a station for bending by pressing (10) with a lower shape (11) and a suction shape (15), a plate-suction device (50) that can be displaced longitudinally to transport the glazings (6) from the roller conveyor (7) to the station for bending by pressing (10), and an annular frame (35) that can be displaced horizontally to transport the bent glazings (61) to the cooling station (4). Lower shape (11) is mounted stationary lengthwise and a transfer station (30) is provided between the station for bending by pressing (10) and the cooling station (4). The upper shape can be displaced between the station for bending by pressing (10) and the transfer station (30), in synchronism with the plate-suction device (50).
