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： A heat softened glass sheet is lifted within a heating furnace by a vacuum pickup and moved to a shaping station adjacent the furnace where it is deposited on an aligning frame. The location of the sheet is identified and the frame is moved to position the supported glass sheet at a predetermined location between a pair of vertically aligned upper and lower full surface press faces. A shuttle frame which moves the vacuum pickup has integral vacuum passageways so that vacuum for the pickup can be drawn through the shuttle frame.

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： Bending a glass sheet to a complicated shape that comprises one portion bent sharply relative to a main portion of the sheet involving the use of a vacuum holder, an auxiliary shaping rail and means to correlate the movement of the shaping rail with that of the glass sheet during a bending cycle to insure that the glass sheet is clear of the auxiliary shaping rail except for such time in the glass sheet bending cycle that requires the auxiliary shaping rail to engage the glass sheet portion to be sharply bent against the corresponding portion of the vacuum holder. Another feature incorporated in a preferred embodiment of the present invention facilitates ready removal of glass fragments whenever a flawed glass sheet fractures at or beyond a shaping station outside a furnace where the glass sheet is heated to its deformation temperature.

摘要： A mold includes a pair of spaced elongated deformable members and spaced elongated flexible strap members between and connected to the deformable members with the axis of the deformable members parallel to one another and transverse to the axis of the strap members. A set of a plurality of donut rolls spaced from one another along the length of the strap members is provided in the space between adjacent strap members to move a heat softened glass sheet over the strap members and below shaped surface of a vacuum mold. The strap members are moved to lift the sheet off the rolls toward and into contact with the shaping surface. The deformable members are deformed as the flexible members bias the sheet against the shaped surface. Vacuum pulled through the shaping surface maintains the sheet against the shaped surface as the strap members move away from the shaped surface.

摘要： The present invention provides a ring mold for shaping heat-softenable sheet material. The mold includes peripheral wall members enclosing a central cavity having an open upper end. The wall members have an upper sheet shaping surface with a peripheral shape and elevational contour that generally corresponds to a desired peripheral shape and elevational contour of a sheet to be shaped. A first set of slots are positioned along and extend through portions of one of the wall members and a second set of slots are positioned along and extend through portions of an opposing wall member. Each of the slots in the second set is generally horizontally aligned with a corresponding slot in the first set.
