    摘要： Disclosed is a method of forming a glass article in which a glass sheet is bent over a forming surface of a chuck. The forming surface defines a first shape including a curvature having a radius of curvature of 1000 mm or less, and the glass sheet includes a first major surface in contact with the forming surface. A frame is adhered to a second major surface of the glass sheet. The frame includes a frame support surface defining a second shape including a second curvature having a second radius of curvature of 1000 mm or less. A total force is applied to the glass sheet so that the glass sheet forms a third shape including a third curvature having a third radius of curvature of 1000 mm or less. The third shape deviates from the second shape by 2 mm or less across the frame support surface.

    摘要： 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.
