Abstract: According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt from a molten core glass and at least one molten cladding glass. The multi-layer glass melt has a width Wm, a melt thickness Tm and a core to cladding thickness ratio Tc:Tcl. The multi-layer glass melt is directed onto the surface of a molten metal bath contained in a float tank. The width Wm of the multi-layer glass melt is less than the width Wf of the float tank prior to the multi-layer glass melt entering the float tank. The multi-layer glass melt flows over the surface of the molten metal bath such that the width Wm of the multi-layer glass melt increases, the melt thickness Tm decreases, and the core to cladding thickness ratio Tc:Tcl remains constant as the multi-layer glass melt solidifies into a laminated glass sheet.

Abstract: An apparatus for forming glass tubing is described. The apparatus for forming glass tubing comprises an endless former with an outer surface and an inner passage defining an inner surface. The apparatus for forming glass tubing further comprises two chambers from which molten glass may flow. One chamber flows molten glass to the outer surface of the endless former and another chamber flows molten glass to the inner surface of the endless former. The two flows of molten glass meet at the bottom of the former to form glass tubing.

Abstract: A method of bending a glass sheet includes placing the glass sheet on a support and heating the entire glass sheet to a first viscosity. A band of heat is applied and translated along the selected region of the glass sheet in which a predetermined is to be formed over a time period to form the predetermined in the selected region. The band of heat sectionally heats the selected region to a second viscosity that is lower than the first viscosity. An actuated force is applied to the glass sheet to incrementally form the predetermined bend in the selected region according to the location of the band of heat in the selected region.

The flat portion and the curved portion each respectively define an outer surface and an inner surface with an average thickness between the respective outer and inner surfaces of from about 0.3 mm to about 2 mm. The surface roughness (Ra) of at least one of the respective outer and inner surfaces is less than or equal to about 0.5 nm.

Abstract: Methods for producing glass articles from laminated glass tubing include introducing the glass tubing to a converter. The glass tubing includes a core layer under tensile stress, an outer clad layer under, and an inner clad layer. The methods include forming a feature the glass article at a working end of the laminated glass tubing and separating a glass article from the working end of the laminated glass tubing, which may expose the core layer under tensile stress at the working end of the glass tubing. The method further comprises remediating the exposed portion of the core layer by completely enclosing the core layer in a clad layer. Systems for re-cladding the exposed portion of the core layer as well as glass articles made using the systems and methods are also disclosed.

Abstract: A local bend is formed in a glass sheet (10) by supporting large flat areas (14, 16) of the glass sheet (10) on large flat supports (106L, 106R) that are articulated relative to each other while leaving an area (12) of the glass sheet in which the local bend is to be formed unsupported. A combination of bending forces applied to the glass sheet (10) by articulation of the large flat supports (106L, 106R) and local heating (110) of the unsupported area (12) of the glass sheet (10) produces the local bend.
