    Abstract: Embodiments of this disclosure include a cold-formed cover glass substrate comprising a first end, a second end opposing the first end, opposing first and second major surfaces, a width, a length; a first axis and a second axis both extending along the width or both extending along the length; a first portion extending from the first axis to the first end that comprises a first radius of curvature, and a second portion extending from the first axis to the second axis. In one or more embodiments, the second portion includes a second radius of curvature that increases or decreases from the first axis to the second axis. In one or more embodiments, the cold-formed cover glass substrate comprises a third portion extending from the second axis to the second end, wherein the third portion differs from the first portion.

    Abstract: 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.
