Embodiments of this disclosure pertains to methods for controlling adhesive bondline while cold-bending a glass substrate. The method includes forming a frame to define a viewing area at least partially surrounded by the frame; shaping the frame to include at least one curvature; positioning a spacer proximate the frame, the spacer comprising: a border area; and a protrusion extending from the border area; engaging the border area of the spacer with the frame to insert the protrusion through the viewing area, wherein the protrusion extends beyond the frame a first distance; positioning an adhesive between the frame and the glass substrate alongside the protrusion to control the bondline; engaging a glass substrate with the adhesive and the protrusion to cold form the glass substrate to the shape of the frame; and securing the glass substrate to the spacer to hold the frame against the adhesive to maintain the bondline.

Methods for uniform adhesive bondline control for 3D cold formed curved laminate

Disclosed are embodiments of a vacuum chuck. The vacuum chuck includes a forming surface having a first longitudinal end, a second longitudinal end, and a curved region. The first longitudinal end and the second longitudinal end define a longitudinal axis, and the curved region defines a radius of curvature along the longitudinal axis. A plurality of elongate grooves are formed into the forming surface in the curved region. Each elongate groove of the plurality of elongate grooves has a length, a width, and a depth extending into the forming surface. The length of each elongate groove is greater than the width. At least one conduit is configured for connection to a vacuum source and is disposed beneath the forming surface. The at least one conduit extends transversely across the plurality of elongate grooves, and the at least one conduit is in fluid communication with the plurality of elongate grooves.

Embodiments of a method of cold-forming a glass article are disclosed. In one or more embodiments, the method includes bending a glass sheet over the chuck such that a first major surface of the glass sheets conforms to a bending surface of the chuck. In one or more embodiments, the method includes adhering a frame to the second major surface of the glass sheet such that at least one spacer is positioned between the glass sheet and the frame.

Methods for forming curved glass articles

An apparatus for cold-shaping a glass sheet that includes: a plurality of vacuum chucks configured within a moveable table; a first automated pick mechanism proximate the table; an automated dispensing mechanism proximate the table; and a pressing apparatus. The first pick mechanism is configured to shape a glass sheet onto one of the chucks. The dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame. One of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame. The pressing apparatus is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly. The glass sheet is bendable at ambient temperature. Methods for cold-shaping a glass sheet are also included in the disclosure.

According to embodiments disclosed herein, an apparatus may hold and retain glass articles during processing. The apparatus may define a plurality of receiving volumes for holding glass articles. The apparatus may include a bottom support floor, a glassware-securing member positioned above the bottom support floor, and a cover plate positioned above the glassware-securing member. The bottom support floor may include a plurality of fluid passages, the glassware-securing member may include a plurality of glassware-retaining openings, and the cover plate may include a plurality of fluid passages. Methods for the use of such apparatuses are also disclosed herein.

Apparatuses and methods for holding, retaining, and/or processing glassware articles

Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.

Edge strength testing methods and apparatuses

An apparatus includes a fiber feeding system to deposit a fiber on an edge of the glass article and a laser system. The laser system is positioned to project a first and a second laser beam onto a first and a second side of the fiber, respectively. The laser system is positioned to project a third laser beam onto the edge of the glass article. A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.
