Abstract
The subject of the invention is a method for bending a sheet of glass involving heating the sheet of glass to a softening temperature, transporting the sheet of glass in an essentially horizontal path as far as a station for bending it between two forms, shaping the sheet of glass by pressing between the two forms, cooling the sheet of glass in an appropriate station, these means comprising shaped rollers receive the sheet of glass after it has been bent and said rollers being oriented parallel to the direction defined on the sheet of glass via the direction in which it is conveyed into the bending station.

A method for bending a sheet of glass involving heating the sheet of glass to a softening temperature, transporting the sheet of glass in an essentially horizontal path as far as a station for bending it between two forms, shaping the sheet of glass by pressing between the two forms, cooling the sheet of glass in an appropriate station, characterized in that means comprising shaped rollers receive the sheet of glass after it has been bent and in that the rollers are oriented parallel to the direction defined on the sheet of glass via the direction in which it is conveyed into the bending station.
A bending device comprising a furnace for heating a sheet of glass, a device for supporting and transporting the sheet of glass in an essentially horizontal plane through the furnace as far as a bending station comprising two bending forms, a lower form passing through the transport device to press the sheet of glass against an upper form, the latter comprising means for holding a sheet of glass after it has been shaped, and at least one cooling station, characterized in that at least one shuttle carrying shaped rollers receives a sheet of glass after bending, in that it can move between the bending station and another station and in that the shaped rollers are oriented parallel to the direction defined on the sheet of glass via the direction in which it is conveyed to the bending station.
The device as claimed in one of claims 9 to 16, characterized in that it comprises a cooling station in the continuation of the direction of the device for transporting the sheet of glass and/or at least one cooling station arranged laterally with respect to said transport device.
