Glass sheet forming and annealing system providing edge stress control

A glass sheet forming and annealing system disclosed provides control of edge stresses by maintaining a press formed glass sheet on an annealing ring (72) below a heated upper forming mold (58) within a forming station (12) for slow cooling toward the glass strain point temperature.. . ... Glasstech Inc

Glass sheet support structure

A support structure for supporting a heated glass sheet in connection with a bending operation includes a frame, a support ring adjustably supported on the frame for supporting a peripheral portion of the glass sheet, and multiple rib assemblies associated with the frame. Each rib assembly includes a laterally extending rib supported on the frame and multiple spaced apart support members connected to the rib and configured such that at least a portion of each support member is adjustable with respect to the rib. ... Glasstech Inc

Glass sheet processing system having cooling of conveyor roller ends

A hot glass sheet processing system includes a roller conveyor (22) having sintered bonded fused silica rollers (24) and a roller support structure (34) located within a heated location (32) together with an elongated cooling unit (36) having a housing (38) defining a cooling chamber (40) that receives and has bearings (42) that rotatably support an aligned set of roller ends (30) having end caps (86) adhesively bonded to the roller ends. The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).. ... Glasstech Inc

Lift device for a glass processing system

A lift device for lifting a glass sheet in a glass processing system includes a lift jet array having peripheral lift jet outlets and inner lift jet outlets disposed inwardly of the peripheral lift jet outlets. Furthermore, each lift jet outlet is operable to allow gas to flow toward the glass sheet. ... Glasstech Inc

The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).. ... Glasstech Inc

Glass sheet forming system

A glass sheet forming system (10) has two parallel forming lines (12) that can utilize any two of three forming stations (18) to provide versatility in use for forming different glass sheet jobs of different sizes and shapes while reducing switchover time from one job to the next.. . ... Glasstech Inc

Glass sheet forming system

A system (10) for forming glass sheets includes a glass location sensing assembly (80) having a fluid switch (82) that is actuated by a roller conveyed glass sheet (g) to control operation of transfer apparatus (69) that transfers the glass sheet from the roller conveyor (22) to a forming mold (48) at a design position for forming. A frame of the sensing assembly (80) supports a carriage (124) on which the fluid switch (82) is mounted for lateral movement with respect to the direction of conveyance of the glass sheet (g) so as to sense its leading extremity. ... Glasstech Inc

Method for forming a hot glass sheet with transverse curvature

A glass sheet press forming station (32) and method for press forming hot glass sheets with transverse curvature is performed by initially limiting the central forming of a glass sheet (g) between its end portions upon pickup from a roll conveyor to an upper mold (38) and prior to press forming with an associated lower mold (66) to prevent central area optical distortion of the press formed glass sheet.. . ... Glasstech Inc

System and method for measuring reflected optical distortion in contoured glass sheets

A method for measuring optical distortion in a contoured glass sheet includes the steps of conveying the glass sheet in a first direction, employing at least one display to project a preselected multi-phase non-repeating contrasting pattern, and employing at least one camera, and uniquely pairing each one of the cameras one of the displays. The method may also include controlling each of the cameras to acquire the desired images, analyzing and combining the data acquired by the cameras to construct a definition of the surface of the glass sheet, and performing one or more optical processing operations on the surface data to analyze the optical characteristics of the glass sheet.. ...
