ABSTRACT:
The invention concerns a glass molding process and system according to which glass sheet is heated in a horizontal position in a heating furnace, transferred vertically to an upper mold having a radius of curvature greater than the radius of curvature that it is desired to give the glass sheet and dropped on a bending frame where the glass sinks under the effect of inertia and gravity. Vertical transfer of the glass is obtained by a vacuum created on the periphery of the upper mold.
