Abstract: A system and method for gaging the shape of a curved panel includes, as components, (1) a system and method for acquiring three-dimensional surface data corresponding to the panel, and (2) a system and method for receiving the acquired surface data, comparing the acquired surface to a pre-defined surface description, and developing indicia of the level of conformance of the contoured panel to the pre-defined specification. The surface data acquisition system includes a conveyor for conveying the panel, at least one display projecting a preselected contrasting pattern, and at least one camera. The camera(s) and display(s) are uniquely paired and are mounted in a spaced-apart relationship a known distance and angle from the surface of the panel such that the camera detects the reflected image of the pattern projected on the surface of the panel from its associated display.

Abstract: A system (10) for forming glass sheets includes a glass location sensing assembly (80) having a fluid switch (82) that is actuated by a roller conveyed glass sheet (G) to control operation of transfer apparatus (69) that transfers the glass sheet from the roller conveyor (22) to a forming mold (48) at a design position for forming. A frame of the sensing assembly (80) supports a carriage (124) on which the fluid switch (82) is mounted for lateral movement with respect to the direction of conveyance of the glass sheet (G) so as to sense its leading extremity. A lateral positioner (130) adjusts the lateral position of the carriage (124) and the fluid switch (82) mounted on the carriage.

Abstract: A press station (12) and system (10) for forming glass sheets that are initially formed with an upwardly concave curved shape with end portions (86) and an intermediate portion (88) 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 (86) while the intermediate portion (88) 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.
