ABSTRACT A deformable vacuum mold for shaping glass sheets to complicated shapes includes mold stiffening structure engaging the central portion of the mold, mold lifting means engaging the longitudinal end portions of the vacuum mold to lift the latter relative to the mold stiffening structure and optional bar means adjustable in position and orientation to provide local control imparted to the shape of the vacuum mold when the longitudi- nal end portions of the mold are lifted. The deformable vacuum mold may also include a pair of lifting means providing different amounts of lift to the longitudinal end portions on opposite sides of the longitudinal center line of the mold and approximately equal amounts of lift to the longitudi- nal end portions on opposite sides of the transverse center line of the mold.
