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.

Glass articles made from laminated glass tubing and systems and methods for converting laminated glass tubing into the glass articles

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.

Overflow downdraw glass tube forming apparatus

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.

Manufacturing process to reform glass tubes

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 W, a melt thickness Tand a core to cladding thickness ratio T:T. The multi-layer glass melt is directed onto the surface of a molten metal bath contained in a float tank. The width Wof the multi-layer glass melt is less than the width Wof 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 Wof the multi-layer glass melt increases, the melt thickness Tdecreases, and the core to cladding thickness ratio T:Tremains constant as the multi-layer glass melt solidifies into a laminated glass sheet.

Methods and apparatuses for producing laminated glass sheets

A method for bending a sheet of material into a shaped article includes providing the sheet of material. A reformable area and a non-reformable area of the sheet of material are heated to a first temperature range corresponding to a first viscosity range. The reformable area of the sheet of material is subsequently heated to a second temperature range corresponding to a second viscosity range. The reformable area of the sheet of material is reformed into a selected shape by at least one of sagging the reformable area of the sheet of material and applying a force to the sheet of material outside of or near a boundary of the reformable area.

Method and apparatus for bending a sheet of material into a shaped article

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.

Methods of fabricating glass articles by laser damage and etching

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.

A glass forming system () and a method are described herein for forming a glass sheet (). In one example, the glass forming system and method can use a glass composition with a liquidus viscosity less than 1000 poises to continuously form a glass sheet.

System and method for forming a glass sheet

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 W, a melt thickness Tand a core to cladding thickness ratio T:T. The multi-layer glass melt () is directed onto the surface of a molten metal bath () contained in a float tank (). The width Wof the multi-layer glass melt () is less than the width Wof the float tank () prior to the multi-layer glass melt () entering the float tank (). The multilayer glass melt () flows over the surface of the molten metal bath () such that the width Wof the multi-layer glass melt () increases, the melt thickness Tdecreases, and the core to cladding thickness ratio T:Tremains constant as the multi-layer glass melt () solidifies into a laminated glass sheet. The invention also relates to the associated apparatus.

A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area.
