ABSTRACT:
An air-cooling and tempering apparatus for a glass sheet includes an upper air-blowing unit, which blows cooling air to an upper surface of a bent glass sheet having a high temperature; and a lower air-blowing unit, which blows cooling air to a lower surface of the glass sheet. Each of the upper air-blowing unit and the lower air-blowing unit includes a plurality of air-blowing members provided in a matrix pattern and a plurality of linkages, the linkages coupling adjacent air-blowing members among the plurality of air-blowing members in a row and/or column direction of the matrix pattern.
