Patent ID: 8381547

Claim:
An air-cooling/tempering apparatus for a glass sheet which is in a state of high temperature and bent to have a complexly curved surface wherein the glass is curved from a horizontal plane along a first direction and also along a second direction which is perpendicular to the first direction, comprising: an upper blowing member for blowing a cooling air against an upper surface of a glass sheet in said state of high temperature and bent to have a complexly curved surface; and a lower blowing member for blowing a cooling air against a lower surface of a glass sheet in said state of high temperature and bent to have a complexly curved surface, wherein: the upper blowing member and the lower blowing member each having a plurality of nozzle chambers arranged in parallel with one another with a gap between adjacent nozzle chambers, and each nozzle chamber is provided with a plurality of air-blowing openings facing to the glass sheet to form an end face for each of the upper and lower blowing members, respectively, the end face of the lower blowing member has a curved shape configured to be substantially perpendicular to the complexly curved surface, and each of the plurality of nozzle chambers has a central portion which extends along a first direction, and a side portion which extends along a second direction that is angled with respect to the first direction in plan view.
