Abstract: A vacuum mold shuttle system in a glass sheet forming system includes a vacuum mold mounted on a support frame. A shuttle frame including a pair of generally parallel elongate beams for receiving and supporting the mold support frame thereon. A vacuum source is mounted on the shuttle frame near the end of the beams opposite to the end supporting the mold, a conduit and coupling port for releasably connecting the mold to the vacuum source. At least one guide element is mounted on the support surface of one of the beams for receiving and fixing the position of the mold support frame relative to the shuttle frame to align and prevent movement of the mold support frame with respect to the shuttle frame in any direction as the mold support frame is supported thereon.

Abstract: An articulated lower mold arrangement for use with an upper mold includes a mold portion configured to bend a heated glass sheet. The mold portion has a first end, a sharp bend area proximate the first end for bending an end portion of the glass sheet, and a second end opposite the first end and spaced away from the sharp bend area. The arrangement may further include a first guide member connected to the mold portion at a first location proximate the first end, and a second guide member connected to the mold portion at a second location proximate the second end and spaced away from the sharp bend area. The mold portion and the guide members are cooperable to allow the first end of the mold portion to move from a lowered position to a raised position in order to move the end portion of the glass sheet upwardly.

Abstract: A mold shuttle positioning system in a glass sheet forming system includes a mold mounted on a support frame. A shuttle frame including a pair of generally parallel elongate beams for receiving and supporting the mold support frame thereon. At least one support wheel assembly including a wheel and a shuttle guide is mounted in proximity to each of the shuttle beams to position and support each one of the beams as the shuttle frame is moved to position the mold supported thereon at one of multiple desired processing locations. At least one mold guide is mounted on the support surface of one of the beams for receiving and fixing the position of the mold support frame relative to the shuttle frame to align and prevent movement of the mold support frame with respect to the shuttle frame in any direction as the mold support frame is supported thereon.

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 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.
