AIR-COOLING/TEMPERING APPARATUS FOR GLASS SHEET, AND AIR-COOLING/TEMPERING METHOD

摘要

It is an object of the present invention to provide an air-cooling/tempering apparatus for glass sheet and an air-cooling/tempering method, which can properly temper a glass sheet bent to have a complexly curved surface, without increasing the heating temperature of the glass sheet or increasing a wind pressure from air-blowing openings. A lower blowing member of the air-cooling/tempering apparatus of the present invention is constituted by a plurality of blade-shaped members arranged into a comb-tooth shape each having a front end face provided with a plurality of arranged air-blowing openings. Further, each blade-shaped member is configured to have a shape whose front end face has a concave curve so that a gap from the plurality of air-blowing openings to the bent glass sheet G becomes substantially uniform. Then, the arrangement of the plurality of air-blowing openings provided on the front end face of each blade-shaped member is turned with a predetermined angle and extends in one direction in each side portion in plan view.
