The present invention provides improved cooling of a veil of glass fibers by using a combination of nozzle assemblies. The nozzle assemblies include air caps of differing configurations to control the penetration of the spray into the veil. One suitable spray configuration is a nozzle assembly having punch air cap that creates a narrow exit angle, high velocity flow of droplets to penetrate the veil to cool the fibers at the interior. Another suitable configuration is a nozzle assembly having a flat air cap that creates a wide exit angle, low velocity, dispersed spray pattern to cool the exterior of the veil. Preferably, the flat air cap creates a very fine particle size to increase the cooling efficiency of the spray. By using the cooling ring of the present invention, lower levels of binder to be applied to the fibers and environmental emissions from the plant may be reduced.
