METHOD AND DEVICE FOR BENDING A GLASS SHEET

After softening in a furnace 1, the glass sheet (10) passes through a device (2) where it is bent between rollers (27, 29) and solidified by cooling through blowing boxes (30). Upstream of the cooling operation, air (5) or another gas is locally blown onto the glass sheet (10) by means of a nozzle system (5) in order to modify its final curve. The local gas blowing is controlled depending on the time that has elapsed since the detection of the arrival of the glass sheet (10) in the device (2). Controlling the local blowing may cause movement of the blowing impact zone on the glass sheet, activation and deactivation of the local gas blowing (10) and/or modification of the local gas blowing pressure. This creates greater flexibility for influencing the final shape of the curved glass sheet (10).
