Abstract:
The method of continuously producing flat glass includes rolling a fluid glass sheet between upper and lower shaping rollers to shape and calibrate the glass sheet, generating a respective gas cushion between the fluid glass sheet and each shaping roller from a liquid, controlling the pressure of the gas cushion between the fluid glass sheet and the upper shaping roller to completely prevent contact of the glass sheet with the upper shaping roller, controlling the pressure of the gas cushion between the fluid glass sheet and the lower shaping roller to form a linear contact area between the fluid glass sheet and the lower shaping roller and controlling the contact area width according to speed and viscosity of the glass sheet in order to transport it without slipping and reduce cooling path length.
