Abstract:
1. A method of making a shaped glass article, comprising: (a) providing a flat glass sheet; (b) providing a mold having a mold cavity defined by a shaping surface, the shaping surface having a surface profile of the shaped glass article; (c) providing at least one edge alignment pin on the mold at an edge of the shaping surface or on the shaping surface; (d) aligning the glass sheet on the mold by placing the glass sheet on the mold such that an edge of the glass sheet abuts the at least one edge alignment pin and tilting the mold such that the edge of the glass sheet abutting the at least one edge alignment pin latches onto the at least one edge alignment pin by gravity; (e) heating the glass sheet; (f) sagging the glass sheet onto the shaping surface of the mold so that the glass sheet assumes the surface profile of the shaped glass article and thereby form the shaped glass article, wherein the at least one edge alignment pin aligns the edge of the glass sheet with the mold cavity as the glass sheet sags onto the shaping surface of the mold; and (g) removing the shaped glass article from the mold; wherein the at least one edge alignment pin provided in step (c) is a stepped pin having an enlarged part and a slender part, and wherein the aligning of step (d) the end of the glass sheet abuts the slender part.
