    摘要: An apparatus for forming a glass ribbon includes a forming body with opposing first and second forming surfaces. An end dam assembly includes a first forming dam wall extending in a draw direction along a first end of the first forming surface. A second forming dam wall can extend in the draw direction along a first end of the second forming surface.

    摘要: According to one embodiment, a method of forming a laminated glass ribbon may include flowing a molten glass core composition and a molten glass cladding composition in a vertically downward direction. The molten glass core composition may be contacted with the molten glass cladding composition to form the laminated glass ribbon comprising a glass core layer formed from the molten glass core composition and a glass cladding layer formed from the molten glass cladding composition. Core beads located proximate an edge of the glass core layer and clad beads located proximate an edge of the glass cladding layer may be compressed while the glass core layer and the glass cladding layers have viscosities greater than or equal to the viscosity at their softening points as the laminated glass ribbon is drawn in the vertically downward direction.

    摘要: A method of cutting a laminate glass article is disclosed. The method comprises heating at least a portion of a laminate glass article to a reheat temperature. The laminate glass article has a core layer and a first cladding layer and is in stress characterized by a thermally-induced differential stress between the core layer and first cladding layer. The laminate glass article having been set at a setting temperature and the reheat temperature is lower than the setting temperature. The heating of the laminate glass article reduces the thermally-induced differential stress between the core layer and first cladding layer. The method may further comprise scoring the laminate glass article in the heated portion to create a score in the laminate glass article along a cutting line and bending the laminate glass article at the score to cut the glass.

    摘要: A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer,

    摘要: A glass article includes a glass core layer and a glass cladding layer adjacent to the core layer. A coefficient of thermal expansion (CTE) of the core layer is greater than a CTE of the cladding layer. The core layer has a tensile stress, and the cladding layer has a compressive stress. A retained strength of the glass article is a strength determined after abrasion of an outer surface of the glass article with 1 mL of 90 grit SiC particles for 5 seconds at an abrasion pressure, and a ratio of the retained strength at an abrasion pressure of 25 psi to the retained strength at an abrasion pressure of 5 psi is at least about 0.3.
