Abstract
A device for forming glass sheets for using the forming process according to which the glass sheets are brought horizontally into a heating furnace then are brought to a forming station where they are transferred individually and vertically to an upper mold exhibiting a radius of curvature less than or equal to the one it is desired to impart to the glass, then are applied against the upper mold by a suction due to a low pressure created on their periphery and in the vicinity of their periphery. The device essentially comprises a suction box in which is placed an upper mold with dimensions slightly less than those of the glass sheet to be shaped and whose lower face, against which the glass sheet is applied, is located on the outside of said suction box.
