Abstract
A heat softened glass sheet is shaped between a contoured upper mold and a flexible lower ring mold. The flexible shaping surface of the lower mold has a generally flat surface configuration as it initially contacts and lifts the peripheral portions of the glass sheet off a series of conveying rolls. The lower mold continues to bias the glass sheet against the upper mold and deforms to substantially compliment a corresponding peripheral portion of the contoured upper mold.
