Abstract
The invention relates to a press-bending method and apparatus for bending glass sheets. The press bending is effected between an upper curved mold surface (12) and a lower ring mold (13). Air is blown through pores included in an upper mold (2) into a space (3) between mold surface (12) and a glass sheet (11), and vacuumed from the edges of the space for developing in the space (3) a negative pressure (P.sub.2) capable of bearing a glass sheet (1) in the immediate proximity of the mold surface (12), yet without contacting the mold surface (12).
