Beschreibung
Zusammenfassung:	A flexible shaping ring for shaping heat softened glass sheets lifts a heat softened glass sheet and presses it against the shaping surface of an upper mold. As the shaping ring presses the marginal edge portion of the sheet against the upper mold, its shaping surface deforms to generally conform to a corresponding portion of the upper mold. A press ring subsequently contacts the shaping ring and presses it against the upper mold to further shape the marginal edge portion of the glass sheet and ensure the marginal edge completely conforms to the shape of the upper mold.
