    摘要: A press bending apparatus includes a shaping station having an upper mold with a shaping surface having a generally concave downward elevational configuration and a lower mold with an apertured shaping surface complementing the shaping surface of the upper mold. A vacuum shuttle transfers heat softened glass sheets from a heating furnace to the shaping station where it deposits the glass sheets on the lower vacuum mold. The glass sheet is shaped between the molds. A rotating arrangement rotates the lower mold and the shaped glass sheet held thereagainst by vacuum from a first position wherein the shaping surface of the lower mold faces upward to a second position wherein the shaping surface of the lower mold faces downward. The shaped glass sheet is then deposited on a tempering ring. A rotating arrangement maintains vacuum in the lower mold as the mold rotates.

    摘要: Sheets of heat-deformable material, such as glass, are shaped to non-uniform curvatures that include a localized sharply bent portion near one side portion of the sheet by lifting the sheet while the latter is at a deformation temperature range on a lower lifting mold of special construction that includes spaced, transversely extending slats having upper edge surfaces defining the non-uniform bend and a longitudinally extending end slat whose upper edge surface defines a transverse curve that merges with the upper edge surfaces of said transversely extending slats.

    摘要: A deformable vacuum mold for shaping glass sheets to complicated shapes includes mold stiffening structure engaging the central portion of the mold, mold lifting means engaging the longitudinal end portions of the vacuum mold to lift the latter relative to the mold stiffening structure and optional bar means adjustable in position and orientation to provide local control imparted to the shape of the vacuum mold when the longitudinal end portions of the mold are lifted. The deformable vacuum mold may also include a pair of lifting means providing different amounts of lift to the longitudinal end portions on opposite sides of the longitudinal center line of the mold and approximately equal amounts of lift to the longitudinal end portions on opposite sides of the transverse center line of the mold.

    摘要: A horizontal press bending arrangement for press bending heat softened glass sheets during transfer into a shaping station. The glass sheet is conveyed through a roller hearth or gaseous support hearth type furnace to heat the sheet to its heat deformable temperature. The sheet is then transferred beneath a vacuum/pressure pick-up to support the glass sheet in non-engaging contact therewith. The sheet is next deposited on a lower mold. The vacuum/pressure pick-up thereafter splits in two and moves out of the shaping station to allow the sheet to be shaped between a pair of vertically aligned shaping molds. After shaping the shaped sheet is removed for further processing, e.g., tempering.

    摘要: A glass sheet is press bent between a pair of bending molds of complementary shape provided with covers using burning gas source means that supplies heat by directing burning gas flames toward the bottom edge of a glass sheet. The burning gas source means is constructed and arranged to be directed toward the path taken by the glass sheet when the latter moves into a shaping position with the press bending molds retracted and to pivot away from the mold covers when the press bending molds engage the glass sheet including its bottom edge during the shaping of the sheet. Preferably, the burning gas source means has a shape that conforms with the shape of the bottom edge of the glass sheet undergoing press bending and has an upwardly directed downstream portion to provide clearance as the glass sheet moves into said shaping position in a direction such that a recessed lower edge portion thereof is the leading edge of the glass sheet during its path of movement into the shaping station.
