The present disclosure is directed to methods and techniques for gob-pressing a glass part of challenging geometries, such as large surfaces with thin thickness as well as features positioned far from a centroid of the part.

Glass parts and gob-pressing methods for making such

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

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.

Methods for forming thin glass sheets

Glass-ceramics exhibiting a Vickers indentation crack initiation threshold of at least 15 kgf are disclosed. These glass-ceramics may be ion exchangeable or ion exchanged. The glass-ceramics include a crystalline and amorphous phases generated by subjecting a thin precursor glass article to ceramming cycle having an average cooling rate in the range from about 10° C./minute to about 25° C./minute. In one or more embodiments, the crystalline phase may comprise at least 20 wt % of the glass-ceramics. The glass-ceramics may include β-spodumene ss as the predominant crystalline phase and may exhibit an opacity≥about 85% over the wavelength range of 400-700 nm for an about 0.8 mm thickness and colors an observer angle of 10° and a CIE illuminant F02 determined with specular reflectance included of a* between −3 and +3, b* between −6 and +6, and L* between 88 and 97.

Crack-resistant glass-ceramic articles and methods for making the same

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.

Systems and methods for processing a glass ribbon

Embodiments of a method of forming a glass article are disclosed. The methods include supplying a glass ribbon in a first direction and redirecting the glass ribbon to a second direction different from the first direction without contacting the glass ribbon with a solid material. The glass ribbon may exhibit a viscosity of less than about 10Poise and a thickness of about 1 mm or less. Embodiments of a glass or glass-ceramic forming apparatus are also disclosed. The apparatus may include a glass feed device for supplying a glass ribbon in a first direction and a redirection system disposed underneath the glass feed device for redirecting the glass ribbon to a second direction. In one or more embodiments, the redirection system comprising at least one gas bearing system for supplying a gas film to support the glass ribbon.

Apparatus and method for forming thin glass articles

A system and process for forming a curved glass laminate article is provided. The process and system utilizes a separation material, such as solid lubricating material and/or a spray applied separation material that Applicant has determined reduces bending dot formation during co-sagging shaping of glass sheets. The bending dot reduction provided by the separation materials discussed herein is particularly seen when the pair of glass sheets have significantly different thicknesses and/or viscosities from each other.

Process for forming curved glass laminate article formed using separation material

Disclosed are apparatuses and methods for non-contact processing a substrate, for example a glass substrate, overtop a gas layer. The support apparatus includes a plurality of gas bearings positioned on a pressure box supplied with a pressurized gas. Some embodiments are directed to a method of supporting and transporting softened glass. The method includes placing the glass in proximity to a gas bearing device having a support surface with a plurality of outlet ports disposed therein. Some embodiments are directed to a glass processing apparatus comprising an air table configured to continuously transport and support a stream of glass and a plurality of modular devices supported by a support structure and disposed above the air table. Some embodiments are directed to a method for flattening viscous glass using a two-sided gas bearing device or a one-sided gas bearing device.

Apparatus and method for processing a glass substrate

A slot orifice design that delivers glass ribbon at a uniform temperature and flow across the slot orifice width is provided. The slot orifice design can include a transition section, a pressure tank, and a slot extension.

Method and apparatus for processing glass

Disclosed is an apparatus and method of making molten glass. The apparatus includes a glass former having a slot orifice design to deliver a glass ribbon. The slot orifice design can include a transition section, a slot extension, and external structural reinforcements. In some embodiments, the orifice opening distance of the slot extension varies along the width of the orifice. In some embodiments, the orifice has an orifice opening distance that is smaller at the center of the slot extension than at the edges of the slot extension, which limits glass flow at the center of the slot extension. Also disclosed is a method of making glass using the disclosed apparatus.

Methods and apparatus for processing glass

Glass-ceramics exhibiting a Vickers indentation crack initiation threshold of at least 15 kgf are disclosed. These glass-ceramics may be ion exchangeable or ion exchanged.
