A method of manufacturing a glass roll, includes: a forming step (S1) of forming, while conveying a glass film, the glass film by a downdraw method; a temporary rolling step (S3) of rolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying in the forming step (S1), to thereby manufacture a source glass roll; and a main rolling step (S4) of unrolling, while conveying the glass film to a downstream side, the glass film from the source glass roll, and then rerolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying, to thereby manufacture a glass roll. Higher tension in a rolling direction is applied to the glass film in the main rolling step (S4) than in the temporary rolling step (S3).

A method for the continuous production of a cellular ceramic plate having asymmetric cells comprising thermally treating ceramic particles and a blowing agent in a foaming furnace while conveying said ceramic particles and said blowing agent at a first speed thereby forming a cellular ceramic plate, and annealing said cellular ceramic plate in an annealing lehr by cooling it down while conveying it at a second speed, larger than said first speed, thereby stretching and cooling said cellular ceramic plate.

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. A lateral positioner (130) adjusts the lateral position of the carriage (124) and the fluid switch (82) mounted on the carriage.

A hot glass sheet processing system includes a conveyor roller support structure (34) located within a heated location (32) and has 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). 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).

The present disclosure relates to a rotary transition section and a tempering and forming apparatus for forming bent glass. The rotary transition section includes a main rack and an auxiliary rack. A plurality of flexible shaft rollers for forming glass are arranged at intervals on the auxiliary rack along the glass conveying direction. An end of the auxiliary rack that is closer to a heating furnace is rotatably connected to the main rack. An end of the auxiliary rack that is away from the heating furnace is connected to a traction mechanism arranged on the main rack. In the tempering and forming apparatus employing the rotary transition section, a forming and tempering section has a lifting function to achieve abutment against a roller surface after the rotation of the transition section, which in turn solves the technical problem that the edge of the glass is difficult to form.

Disclosed in the present invention is an apparatus for eliminating stress spots on a surface of glass, comprising a conveying assembly, provided with a conveying surface for reciprocally conveying the glass along a conveying direction; an upper air-blowing assembly, provided above the conveying surface, used for guiding air to reciprocally flow above the conveying surface along a swinging direction extending along a width direction of the glass; and a lower air-blowing assembly, provided under the conveying surface, used for guiding air to reciprocally flow under the conveying surface along the swinging direction. A method for eliminating stress spots on a surface of glass comprises a conveying step, a glass swinging step, and an air-cooling step.
