A glass sheet forming station for forming a glass sheet may include an upper mold, a lower outer mold arrangement and a lower inner mold arrangement disposed inwardly of the lower outer mold arrangement and movable relative to the lower outer mold arrangement. The lower outer mold arrangement may include first and second outer longitudinal support portions and first and second outer lateral support portions that are each configured to contact the glass sheet. The lower inner mold arrangement may include first and second inner longitudinal support portions and first and second inner lateral support portions that are each configured to contact the glass sheet. Furthermore, the lower outer mold arrangement and the lower inner mold arrangement may each be operable to press the glass sheet against the upper mold.

Station and method for forming glass sheets

A support structure for supporting a heated glass sheet in connection with a bending operation includes a frame, a support ring adjustably supported on the frame for supporting a peripheral portion of the glass sheet, and multiple rib assemblies associated with the frame. Each rib assembly includes a laterally extending rib supported on the frame and multiple spaced apart support members connected to the rib and configured such that at least a portion of each support member is adjustable with respect to the rib. Furthermore, each support member is configured to contact a respective inner portion of the glass sheet to support the respective inner portion of the glass sheet until the glass sheet has been sufficiently cooled.

Glass sheet support structure

A press station () and system () for forming glass sheets that are initially formed with an upwardly concave curved shape with end portions () and an intermediate portion () having straight line elements that are subsequently formed with curved shapes to provide curvature along transverse directions. The forming is performed by initially providing curvature to the straight line elements of the glass sheet end portions () while the intermediate portion () still has the straight line elements. The glass sheet intermediate portion is subsequently formed to provide curvature to its straight line elements so the entire glass sheet has curvature in transverse directions.

Station and system for press forming glass sheets

A glass sheet forming method utilizes first and second upper molds and a lower mold to provide three stage forming. The glass is curved on the upper mold in the first stage but retains straight line elements transverse to the curvature. Transfer of the initially formed glass sheet from the first upper mold to the lower mold then provides the second stage of gravity forming and the glass sheet is then press formed between the second upper mold and the lower mold in the third stage which reduces optical distortion in the central viewing area of the formed glass sheet. In one embodiment the glass sheet is moved horizontally on the lower mold, and in another embodiment the glass sheet is moved horizontally on the first upper mold.

Method for three stage forming a hot glass sheet with transverse curvature

A method for supporting a heated glass sheet in connection with a glass processing operation may include adjusting a support structure so that multiple spaced apart support members of the support structure cooperate to define a shape that corresponds to a desired end shape of the glass sheet. The method may further include contacting the glass sheet with the support members until the glass sheet has been sufficiently cooled. Furthermore, the support structure may include a frame and a support assembly associated with the frame, the support assembly including the support members and a support connected to the support members such that at least a portion of each support member is adjustable with respect to the support. The support may further be connected to the frame at two locations on the frame such that the support spans an open area between the two locations on the frame.

The glass sheet is moved horizontally on the first upper mold and released onto the lower mold.
