Abstract:
A method of making individual glass panes each having a thickness between 0.03 mm and 2 mm, said method comprising the steps of:a) drawing a glass band vertically downward from a hot forming device through a vertical zone at a temperature below a lower cooling point of the glass band; b) subsequently deflecting the glass band in a bending zone, in which the glass band is freely suspended and has a bending radius of between 0.1 m and 4 m, so that the glass band passes from the bending zone into a horizontal zone in which the glass band has a substantially horizontal orientation; and c) cutting edge portions from the glass band in an edge cutting process; and d) cutting the glass band to length to form the individual glass panes in another cutting process; wherein at least one of the cutting processes occurs in the horizontal zone in which the glass band is in the substantially horizontal orientation.
