    摘要: A method and furnace for heating a glass sheet by lower electric resistance elements (50) supported by a furnace housing (12) below a roll conveyor (40) and by supplying a gas burner heated hot gas flow from a forced convection heater (56) that provides a dominant mode of external heat for heating the conveyed glass sheet from above. The furnace can also be manufactured by retrofitting an electric resistance heater type glass sheet furnace.

    摘要: A system (20) and method for forming a glass sheet includes a locating assembly (28) for locating at least one glass sheet below a downwardly facing surface (58) of a topside support device (26) that receives the heated glass sheet from a conveyor (24, 24') in preparation for transfer thereof to an associated mold (33) on a mold shuttle (30). The locating assembly (28) includes a support (82) that is mounted outside of the system housing (22) at factory ambient temperature and has a horizontal arm (84) extending therefrom through the housing into its heated chamber (37) with first and second locators (92) and (94) for locating the suspended glass sheet as well as having a third locator that cooperates with the first and second locators to provide the glass sheet location. The first and second locators (92) and (94) are rotatively driven. In one embodiment designed to form a pair of glass sheets during each forming cycle, a pair of the horizontal arms (84) are used and a pair of the third locators (96) are provided mounted on the downwardly facing surface of the topside support device (26). In another embodiment for processing a single glass sheet during each cycle, the third locator (96) is mounted on another horizontal arm (84a) on which a fourth locator (97) is also mounted. Both air hearth and roll conveyors (24, 24') can be utilized to transfer the glass sheet to the topside support device (26) for the location.

    摘要: A system (10) and method for forming glass sheets includes a forming station (14) having lower and upper molds (28, 30) between which glass sheets G are cyclically received from a furnace (12) on a vacuum transfer platen (34), formed between the lower and upper molds (28, 30), and transferred to a delivery mold (42) for delivery such as to a quench station (16). The vacuum transfer platen (34) and the delivery mold (42) are moved at different elevations and operated by a controller (18) for movement into the forming station (14) in respective underlapping and overlapping relationships to each other so each glass sheet forming cycle can begin within the forming station before the prior forming cycle is completed in a time overlapping manner that reduces the cycle time.

    摘要: A method for making a furnace for heating a glass sheet by lower electric resistance elements (50) supported by a furnace housing (12) below a roll conveyor (40) and by supplying a gas burner heated hot gas flow from a forced convection heater (56) that provides a dominant mode of external heat for heating the conveyed glass sheet from above. The furnace is manufactured by retrofitting an electric resistance heater type glass sheet furnace that initially has both lower and upper electric resistance elements (50) located below and above the roller conveyor (40). The lower electric resistance elements (50) are maintained while the upper electric resistance elements (50) are replaced with a gas burner forced convection heater (56).

    摘要: A cooling ring assembly (20) and method for controlling stresses in a bent glass sheet G produce a strengthened bent glass sheet after the cooling is completed. The cooling ring assembly includes a cooling ring (22) that supports the glass sheet edge (24), an insulator (30) juxtaposed inboard of the cooling ring to reduce the cooling rate, and a cooler (34) for providing increased cooling by pressurized air to at least one localized area (36,40,58) of the glass sheet edge. The cooler (34) is preferably embodied by a pressurized air supply (42).
