Abstract
An air-cooling/tempering apparatus and 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 includes a plurality of blade-shaped members arranged into a combtooth shape each having a front end face provided with a plurality of arranged air-blowing openings. Each blade-shaped member has a front end face with a concave curve so that a gap from the plurality of airblowing openings to the bent glass sheet becomes substantially uniform. The arrangement 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.
