Abstract
The invention relates to a method for the manufacture of a curved double sheet of glass intended for further processing into a sheet of curved laminated safety glass. In a horizontal position the glass sheets are heated successively to bending temperature in a roller oven and are successively bent in a bending station subsequent to the roller oven, in that the sheets are pressed against a bending mold (2) arranged above the transport rollers (1) by a hot gas stream directed against the glass sheets from beneath. After bending, the first glass sheet (10) of a pair of glass sheets is held in a waiting position in such a manner that its shape is supported. After the bending of the second individual glass sheet (10'), the two glass sheets (10, 10') are stacked and cooled together.
