ABSTRACT:
Compression stresses are formed on the periphery of a glass sheet by blowing cooling air on the periphery of the heated glass sheet. The cooling air is blown by using a pyramidal deflector to deflect air flow radially outward toward the edges of the glass sheet. By adjusting the spacing between the deflector and the glass sheet, the size of a central, relatively quiescent, zone can be adjusted. The air flow is provided by a duct which can include a pyramidal skirt which surrounds the deflector to form a gas flow path whose size controls the cooling rate. Pyramidal flaps within the gas flow path can be used for adjusting cooling gas pressures.
