Abstract
Method and apparatus for bending glass sheets, characterized in that the first comprises the phase of placing a glass box to be curved in the bending position on a mold having a configuration surface, said mold moving along a predetermined course through a furnace and heating the glass sheet as it passes through the furnace at a temperature at which the sheet will soften and curl in accordance with the mold configuration surface, thereby reducing the temperature of the glass thus curved below the precise temperature for bending, and separating the curved sheet from the configuration surface of the mold, while said sheet is at a relatively high temperature, but after having been cooled until it reaches the proper state of rigidity.
