The first platen (14) is deformable and includes an actuator (16) for deforming platen (14) from a planar shape to a bent shape. A second platen (22) is mounted above lower platen (14) for bending and quenching glass sheet (12) therebetween the platens. A template (24) is located on the other side of the second platen (22) away from glass sheet (12). Second platen (22) is pressed against template (24) as first platen (14) is deformed from the planar shape to the bent shape to bend the heated glass sheet thereagainst second platen (22), the second platen (22) conforming to template (24). Quenching gas is supplied by both platens (14,22) through quench openings (18) that move with the platens (14,22) to temper the bent glass sheet between the platens.

摘要： A furnace for heat treating glass sheet material including a circular enclosure having top, bottom and side walls of refractory material. Inlet and outlet openings are formed in the side walls. The side walls have an outer insulating layer and an inner layer of material having a low coefficient of thermal expansion, the inner layer having spaced end portions projecting beyond the outer layers and the periphery of the side walls to define said inlet and outlet openings. Each opening is controlled by doors, and each door includes an elongated support bar with a plurality of blocks of refractory material supported on the bar in end-to-end relationship. The blocks are adjustably secured to the bar to accommodate irregularities in the openings.

摘要： Sheet glass is heated during conveyance within a furance housing having a fixed roof and vertically movable side doors that define side slots through which ends of conveyor rolls project outwardly to be supported and frictionally driven by continuous drive loops slidably driven over external support surfaces that extend alongside the side slots. A vacuum holder of the apparatus is positioned within the furnace housing above the conveyor and has a downwardly facing surface with spaced openings in which a vacuum is drawn to receive a glass sheet from the conveyor and support the sheet above the conveyor. The holder surface is disclosed as being both planar and curved and as having a porous cover of ceramic fibers so as to distribute the vacuum and prevent marring of the glass as it is supported. A greater vacuum is drawn to initially support the glass and a lesser vacuum is subsequently drawn to prevent glass deformation at the spaced openings. Vertically movable auxiliary lifters positioned between the rolls or vertical movement of the vacuum holder facilitates glass pickup. Sensing of the glass position along the conveyor and operation of a locator cooperatively provide accurate positioning of the glass on the holder surface without requiring the conveyor to be stopped prior to the holder operation. A carrier mold ring moves under the supported glass and the vacuum is then terminated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows thin glass to be accurately bent. Subsequently the mold ring is moved from the furnace to a quench unit between upper and lower blastheads that temper the bent glass. Increased air is then supplied to the lower blasthead relative to the upper blasthead to lift the glass sheet off the ring and allow return of the ring to the furnace.

摘要： A roll drive mechanism (14) for a horizontal roller conveyor (12) of glass sheet processing equipment (10) has particular utility with a heating furnace (18) of a glass sheet tempering system. First and second continuous drive loops (22,24) of the drive mechanism extend along the conveyor and are alternately engageable in a driving relationship with conveyor rolls (16) over associated lengths (26,28,30) of the conveyor that are selectively adjustable to provide a desired transition between adjacent conveyor sections driven by different drive loops. First and second electric motor drives (32,34) respectively drive the loops to provide synchronous or independent glass sheet conveyance over the different lengths of the conveyor. A pair of each of the first and second drive loops (22,24) are preferably utilized with opposite ends of the conveyor rolls supported thereon and having driven and reduced size portions (88,90 and 86,92) that permit end-for-end roll repositioning to adjust the transition between the driving of the loops. The preferred construction utilizes chains as the drive loops (22,24) with the roll ends projecting outwardly through side slots (66) in the furnace (18) for frictional driving of the rolls by the chains.

摘要： A method and apparatus for filming and tempering a pre-cut glass sheet in a continuous process. The glass sheet is heated initially to a temperature sufficient for pyrolysis. The heated glass is sprayed with a coating composition which reacts with the glass to form a metal oxide film on its surface. The filmed glass is re-heated to both restore the heat lost by spraying and to bring its temperature to a level sufficient for tempering. The glass sheet is then tempered by subjecting it to rapid cooling. The method can be modified to include a secondary spraying wherein after the glass is first sprayed it is re-heated as in the initial step and then re-sprayed before completing the process. Apparatus for carrying out the above described method is also disclosed.

摘要： A roller hearth furnace having a plurality of horizontally elongated furnace modules aligned with each other in an end-to-end relationship so a roller conveyor may carry glass sheets horizontally through the furnace and thereby heat the glass prior to tempering. Each furnace module has a hollow construction with a circular cross-section defined by a semicircular lower housing portion and a semicircular upper housing portion. A separate counterbalance mechanism associated with each upper housing portion supports it independently of the others for movement between a lower closed position immediately over its associated lower housing portion and an upper open position where the interior of its associated lower housing portion is accessible. The counterbalance mechanisms each include four chains attached to counterweights in a manner that permits counter-balancing of the associated upper housing portion even if one chain should break. One chain of each counterbalance mechanism is driven by an associated reversible electric motor to raise and lower its upper housing portion, and a separate elongated operator handle extending along the length of each upper housing portion is coupled to the motor thereof so an operator can control the motor operation from any position along the length of the particular furnace module. Each upper housing portion includes end walls that mitigate heat loss when one of them is open while adjacent ones are closed. Upper and lower end walls at each end of the furnace are reinforced to maintain horizontal openings of uniform size where glass enters and leaves the furnace.
