SINGLE-CURVED GLASS MANUFACTURING SYSTEM, SINGLE-CURVED GLASS AND SINGLE CURVED GLASS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing technique of a single-curved glass 2 with small difference between the radius of curvature of a front end portion of the glass and that of the rear end portion of the glass.;SOLUTION: The single-curved glass manufacturing apparatus 10 includes a heating furnace 13 and a cooling mechanism 14. The cooling mechanism 14 is provided with a movement means 29 for moving an upper part window box 25 parallel to the moving direction of the glass 12 connected to the upper window box 25. In the apparatus, cooling wind is blown also onto an rear end upper surface T7 at a timing when a rear end lower surface T8 is rapidly cooled and the temperature of the rear end lower surface T8 is equal to the temperature of a rear end upper surface T7. The timing to arrive at the strain point is substantially the same for the rear end upper surface T7 and the rear end lower surface T8. The difference between radius of curvature of the glass front end and the radius of the curvature of the glass rear end is made small.;COPYRIGHT: (C)2011,JPO&INPIT
