Glass-bending apparatus and method

摘要

A sag-bending glass sheet mold is disclosed. The sheet mold comprises a plurality of lateral support members, a plurality of longitudinal support members arranged perpendicular to the lateral support members, each of the plurality of lateral support members extending between two of the plurality of longitudinal support members, each of the plurality of longitudinal support members having an upper surface, and the upper surfaces of each of the plurality of longitudinal support members combined to form a mold support surface. The sheet mold can also comprise a glass-bearing support sheet disposed atop the mold support surface, the glass-bearing support sheet extending across the plurality of longitudinal support members and above the lateral support members, the glass-bearing support sheet having a curved upper surface.

1. A sag-bending glass sheet mold comprising:
a plurality of lateral support members; a plurality of longitudinal support members arranged perpendicular to the lateral support members, each of the plurality of lateral support members extending between two of the plurality of longitudinal support members, each of the plurality of longitudinal support members having an upper surface that is curved about a first axis parallel to the lateral support members; and a capping surface disposed on the upper surface of each longitudinal support member of the plurality of longitudinal support members, each capping surface having a flattened upper surface or a curved upper surface that is curved about a second axis transverse to the first axis, wherein the sag-bending glass sheet mold is adapted to shape a sheet of glass such that, when heated, the sheet of glass sags towards and is shaped by the upper surface of the capping surface.
