1. A glass manufacturing apparatus, comprising:
a forming apparatus defining a travel path extending in a travel direction, the forming apparatus configured to convey a ribbon of glass-forming material along the travel path in the travel direction;
a cooling tube extending substantially parallel to the travel path and extending across the travel direction, the cooling tube comprising a plurality of orifices spaced apparat along the cooling tube and facing the travel path; and
a plurality of nozzles, a nozzle of the plurality of nozzles in fluid communication with a corresponding orifice of the plurality of orifices, the nozzle comprising a mixing chamber configured to receive compressed gas and a cooling fluid, and the nozzle further configured to discharge atomized streams of fluid toward the travel path;
wherein the plurality of orifices are sequentially spaced apart across the travel direction, and wherein the plurality of nozzles comprise:
an inner group of nozzles positioned toward a center of the cooling tube; and
a first outer group of nozzles and a second outer group of nozzles positioned toward ends of the cooling tube, and a diameter of nozzle orifices of the first outer group of nozzles and second outer group of nozzles is larger than a diameter of nozzle orifices of the inner group of nozzles.
