THERMAL BARRIERS TO GUIDE GLASS CUTTING AND PREVENT CRACKOUT |
摘要 |
A method of forming a glass article includes drawing a glass ribbon from a draw housing in a downstream direction, heating portions of only a bead of the glass ribbon to form compressive stress regions in the bead, scoring the glass ribbon to form a score line on which the glass ribbon is broken. The bead is heated at a position upstream from the score line. An apparatus for manufacturing a glass article includes a draw housing for forming a glass ribbon having a bead, a heating apparatus with a heat source for forming compressive stress regions in portions of only the bead of the glass ribbon, and a scoring apparatus that forms a score line on which the glass ribbon is broken to form the glass article. The heat source moves downstream simultaneously with the glass ribbon. |
