Abstract: Apparatus (26) and a method for forming heated glass sheets in a heated chamber (22) of a housing (20) includes an upper mold support assembly (28) for supporting an upper mold (38) within the heated chamber for cyclical vertical movement between upper and lower positions. A lower mold shuttle (50) supports a lower mold (36) for movement between an idle position horizontally spaced from the upper mold and a use position below the lower mold. The apparatus also includes a lower mold support assembly (60) to which the lower mold is transferred from the lower mold shuttle (50) to provide support thereof while permitting horizontal alignment with the upper mold upon each cycle of downward movement to form a heated glass sheet between the molds. The lower mold shuttle (50) is supported by vertically movable rollers (70) to provide the transfer between the lower mold shuttle and the lower mold support assembly (60). A quench station (40) includes a quench shuttle (62) that moves a quench ring (66) to receive the formed glass sheet from the upper mold (38) and to then move the formed glass sheet between lower and upper quench modules (46,48) of the quench station for quenching.

Abstract: A glass sheet processing system for processing a glass sheet includes a conveyor for conveying the glass sheet in a direction of conveyance, and a positioning apparatus for adjusting position of the glass sheet on the conveyor. The positioning apparatus includes a movable carriage having first and second carriage bodies. The first carriage body is translatable in the direction of conveyance, and the second carriage body is supported by the first carriage body such that the second carriage body is movable in a direction generally transverse to the direction of conveyance. The positioning apparatus further includes a first drive assembly for moving the first carriage body in the direction of conveyance, a second drive assembly for moving the second carriage body with respect to the first carriage body, and a positioner member connected to the second carriage body for contacting the glass sheet to adjust position of the glass sheet.

Abstract: 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.

Abstract: A mold apparatus for bending a glass sheet includes a main frame structure and a first mold arrangement having a first mold and a guide frame connected to the first mold. A first guide member of the guide frame is guidable by the frame structure such that it is inhibited from moving laterally in any direction, and a second guide member of the guide frame is guidable by the frame structure such that it is movable laterally away from the first guide member due to thermal expansion. The apparatus further includes a second mold arrangement including a second mold and a frame that supports the second mold such that the second mold is movable laterally relative to the frame. A sensor is also included for sensing position of one of the molds to determine whether the one mold is in a suitable position for mating with the other mold.

Abstract: 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.
