Abstract: Systems and methods for automated, sequential processing of a continuous glass ribbon by conveying the glass ribbon in a ribbon travel direction, forming a score line in the glass ribbon, separating a glass sheet from the glass ribbon at the score line while supporting the glass sheet with a transfer device, lowering the glass sheet onto a conveyor, and conveying the glass sheet in a sheet travel direction differing from the ribbon travel direction. By transferring and then conveying the glass sheet in a direction differing from the ribbon travel direction (e.g., a 90 degree turn) immediately after glass sheet separation, the systems and method of the present disclosure are conducive to streamlined production of glass sheets utilizing a unique production floor footprint.

Abstract: According to one or more embodiments disclosed herein, a glass sheet may be formed by a method which includes supplying a feed of molten glass to an upper surface of a pair of forming rolls, and rotating the pair of forming wheels to continuously form a glass sheet from the molten glass. The pair of forming rolls may be spaced apart by a forming gap, and the forming gap may have a width of less than or equal to about 800 microns. The molten glass may have a viscosity of less than or equal to about 200 poise. The glass sheet may have a thickness of less than or equal to about 800 microns immediately upon passing though the forming gap.

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: The present disclosure provides an apparatus and method for modifying the shape of a hollow structure. The method may comprise steps of providing a hollow structure having a cross-section with first and second diameters defining a first aspect ratio; heating at least a part of the hollow structure to at least its glass transition temperature, forming a malleable hollow structure; maintaining a positive pressure inside the malleable hollow structure to form a pressurized hollow structure; and pressing against a first side and an opposed second side of a heated part of the pressurized hollow structure, forming a hollow tabular structure having first and second opposed generally flat faces and a second aspect ratio greater than the first aspect ratio.

Abstract: A roll forming apparatus includes at least one forming roll being spaced from a forming body to define a gap. The forming roll includes a working zone portion having a working zone surface with a length extending along a rotation axis of the forming roll and a thermal resistance boundary extending at an acute angle relative to the rotation axis. In further examples, methods include the step of feeding a stream of molten glass through the gap to form a glass ribbon including a formed thickness. The thermal resistance boundary facilitates substantial uniform radial expansion of the working zone surface relative to the rotation axis across the length of the working zone surface in response to heating of the working zone portion by the molten glass.
