Abstract: Methods of fabricating formed glass articles are described herein. In one embodiment, a method for fabricating a formed glass article may include forming a glass ribbon, forming a parison, and shaping the parison to form a glass article. The glass article may be attached to the glass ribbon at an attachment region defining an edge of the glass article. The process may also include contacting the attachment region with a focal line of a laser beam and separating the glass article from the glass ribbon at the attachment region. The attachment region may be perforated by the laser beam and the focal line may be substantially perpendicular to the plane of the glass ribbon.

Abstract: A method of separating a transparent mother sheet includes contacting a first surface of the transparent mother sheet with an open ended pressure assembly including a pressure vessel shell, thereby forming a shell cavity defined by the first surface of the transparent mother sheet and the pressure vessel shell, where the transparent mother sheet comprises a damage path. The method also includes removing gas from the shell cavity through a fluid removal outlet extending through the pressure vessel shell to reduce a cavity pressure in the shell cavity, thereby applying stress to the damage path to separate a portion of the transparent mother sheet along the damage path.

Abstract: In some embodiments, a method of forming a glass article comprises perforating a glass substrate along a contour with a laser forming a plurality of perforations, such that the contour separates a first portion of the glass substrate from a second portion of the glass substrate. After perforating, thermal forming the glass substrate into a non-planar shape with a mold, and separating the first portion of the glass substrate from the second portion of the glass substrate.

Abstract: Processes of chamfering and/or beveling an edge of a glass or other substrate of arbitrary shape using lasers are described herein. Three general methods to produce chamfers on glass substrates are disclosed. The first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser. Treatment with the ultra-short laser may be optionally followed by a CO2 laser for fully automated separation. The second method is based on thermal stress peeling of a sharp edge corner, and it has been demonstrated to work with different combination of an ultrashort pulse and/or CO2 lasers. A third method relies on stresses induced by ion exchange to effect separation of material along a fault line produced by an ultra-short laser to form a chamfered edge of desired shape.

Abstract: A system for levitating a softened, viscous or viscoelastic material by near field acoustic levitation. The system includes a support structure having a rigid surface, and a vibration generator operatively connected to the rigid surface. The vibration generator transmits acoustic waves to the rigid surface at a frequency and an amplitude sufficient to vibrate the rigid surface and create a gas squeeze film between the material and the rigid surface. The gas squeeze film has a pressure greater than ambient air pressure and sufficient to levitate the material. The system is particularly suited for transporting, forming, or casting heated glass. Also disclosed are methods for transporting, forming, and casting heated glass using near field acoustic levitation.

Abstract: The present disclosure relates to a process for cutting and separating arbitrary shapes of thin substrates of transparent materials, particularly tailored composite fusion drawn glass sheets, and the disclosure also relates to a glass article prepared by the method. The developed laser method can be tailored for manual separation of the parts from the panel or full laser separation by thermally stressing the desired profile. The self-separation method involves the utilization of an ultra-short pulse laser that can be followed by a CO2 laser (coupled with high pressure air flow) for fully automated separation.
