ABSTRACT OF THE DISCLOSURE A glass sheet for use as an automotive windshield, for example, is shaped by supporting at least a peripheral edge of a glass sheet to be shaped on a ring mold, moving the ring mold into a heating furnace until the glass sheet is positioned directly above a shaping mold in the heat- ing furnace, heating the glass sheet until the glass sheet on the ring mold is softened and deformed to a shape comple- mentary to the ring mold, lifting the shaping mold with respect to the ring mold to transfer the glass sheet from the ring mold onto the shaping mold and attracting the glass sheet against a shaping surface of the shaping mold to shape the glass sheet complimentarily to the shaping surface, low- ering the shaping mold with respect to the ring mold to transfer the shaped glass sheet from the shaping mold onto the ring mold, and moving the ring mold out of the heating furnace. After the glass sheet has been shaped by the shap- ing mold, air is ejected from the shaping surface of the shaping mold toward the glass sheet so that the glass sheet can easily be separated from the shaping surface.
