<p>A nozzle assembly for a flat-glass tempering machine having a nozzle cover (2) which includes two distinct types of orifices side by side. A first series of orifices (7,8) are linked to a first source of compressed air, a compressor (11), and a second series of orifices (6) are linked to a second source of compressed air, a blower (12). Thus, the different orifices supply air of different pressures, suitable for tempering thin glass sheets, and an increase in cooling power can be achieved together with reduction in size of the compressor and blower. <IMAGE></p> |
