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 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.

Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate 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: The present invention is directed to methods for making high quality glass tubes, and apparatuses for making high quality glass tubes. Because glass tubes made using the methods and apparatuses disclosed herein are substantially free from the optical defect known as paneling, the glass tubes may be used in displays for consumer electronic devices. The glass tubes are made by a continuous process in which a flow of molten glass is provided on an inner surface of a hollow, rotating mandrel such that the glass coats the inner surface of the mandrel and flows downstream on the inner surface of the mandrel, during which it is cooled to provide a higher viscosity. The glass is then removed from the mandrel and drawn to obtain a glass tube. A flow of molten glass may also be provided on the outer surface of the mandrel and joined with the glass flow on the inner surface of the mandrel when the glass flows exit the mandrel. The apparatuses presented herein are configured to provide high quality glass tubes using this method.
