Abstract
The invention relates to a nozzle assembly for a flat-glass tempering machine. A nozzle cover (2) includes two types of orifices side by side. A number of orifices (7, 8) are linked to the pressure of a compressor (11) and another number of orifices (6) are linked to the pressure of a blower (12). Thus, the different orifices supply air of different pressures.
Claims8
A cooling assembly for a fiat-glass tempering machine, said tempering machine being provided with a glass sheet supporting conveyor and a plurality of nozzle assemblies positioned above and below said conveyor, each of the nozzle assemblies comprising a nozzle housing and a nozzle cover provided with a plurality of orifices, a first and a second compressed-air source having substantially different pressures, a first portion of the orifices being linked to the first compressed-air source and a second portion of the orifices being linked to the second compressed-air source, the plurality of orifices being included in a common nozzle cover supplying air of different pressures, each of the first and second portion of orifices separately form an orifice pattern sufficiently dense to permit uniform cooling at below maximum rate by one of the first and second portions.
