Abstract
Apparatus (10) for bending glass sheets (12) disclosed provides press bending between a shaping surface (16), and a press ring (26) of a complementary shape. The apparatus (10) utilizes vacuum drawn through vacuum chambers (22, 30) and thereby on the shaping surface (16), to control the bending and avoid negative curvature associated with press bending sharp bends into glass sheets (12).
