Abstract
Process for the manufacture of warped glass sheets, characterized in that it consists of heating a sheet of flat glass, in a uniform manner over its entire extension, to the softening temperature necessary for warping, and to operate this warping, and then to intervene on the sheet a protective screen in front of the part to be reserved when the sheet still has all or part of the heat it has received for the warping, and finally in conducting the thermal operations (heating and/or cooling) according to the tempering of the glass in the part not reserved, in such a way that, depending on the glass of the reserved part, it is at a lower temperature or at least equal to the temperature of the surrounding area, when it solidifies during cooling.
