Abstract

Apparatus for curving elongated glass sheets giving them a curved configuration, comprising molding sections adapted to move to a position in which they are extended or open to receive flat sheets of glass and to a position in which they are closed constituting a frame essentially continuous whose shape responds in elevation and silhouette to the contour desired by the cambered glass sheet, at least one of the molding sections comprising a rail having an upper forming surface whose shape responds to a part of said continuous framework, characterized by having a sliding bar in close proximity to said rail whereby the flat sheet of glass is supported along the edge by a lower angle by the smooth surface sliding bar, when the sections of the mold move to the position in the one that is extended; and when the glass sheets are combined into the shape of the essentially continuous frame, the rail supports a part of the glass inwardly of its periphery the latter being aligned with the space between the running bar and the rail to allow that part of the the periphery of the cambered glass sheet aligned with said space develops a compressive stress upon cooling of the glass while it is still mounted on the bending apparatus, after a bending operation.
