Abstract
The invention relates to an assembly in the annealing section of a glass tempering apparatus, comprising a glass sheet supporting rollers and cooling air blow boxes disposed above and below a glass sheet. A blast pressure applied to the bottom surface of a glass sheet may tend to pick up a glass sheet and float the sheet off contact with the rollers. In order to correct the situation without changing the cooling effects on the opposite surfaces of glass, the radiation absorption factor of surfaces below a glass sheet is higher than the absorption factor of surfaces above on the thermal radiation wavelengths of glass. Thus, the blast pressure on a top surface of the glass sheet has been increased with respect to the blast pressure on a lower surface of the glass sheet.
