ABSTRACT OF THE INVENTION A process for making a convex sheet of glass having a substantial bent portion of small radius of curvature comprising vertically suspending a heated flat sheet of glass between two molds having matching center elements and matching jointed elements mounted on the center elements for movement about an axis, moving the molds together to confine the sheet and moving the jointed elements with respect to the center elements to bend a portion of the heated sheet. A device for making a convex sheet of glass having a bent portion of small radius of curvature including a female mold and a male mold adapted to engage a vertically suspended sheet of glass therebetween and where the molds have matching center elements and at least one set of two matching jointed elements connected to the center elements and including means for moving the jointed elements of a set about an axis to bend a portion of the sheet. -1-
