Abstract
A glass sheet shaping apparatus shapes a curved reinforced glass sheet by bending a glass sheet which has been heated by a heating furnace up to a softening point and thereafter cooling the bent glass sheet with a cooling medium and imparting a prescribed stress to the glass sheet. The glass sheet is bent by upper and lower mold members fixed to respective common plates which are interconnected by positioning rods. The unit assembly comprising these upper and lower mold members and common plates is carried on a carrier and moved by a suitable displacing device onto a lower surface plate located in a frame assembly for replacing the existing unit assembly.
