    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.

    Abstract: A glass article is provided with a cover glass sheet having first and second major surfaces. The second major surface has a first region with a first curve of a first radius of curvature, and a second region that is different than the first region. A frame's support surface has a third region of a first frame material and a fourth region of a different, second frame material. The second major surface faces the support, and the third region includes a second curve that complements the first curve while the fourth region complements the second region. A first adhesive is between the third region and the first region. A second adhesive is disposed between the fourth region and the second region. The first adhesive has a first Youngs modulus, and the second adhesive comprising a second Youngs modulus that is different than the first Youngs modulus.
