Abstract:
A method of cooling a glass filament forming area beneath a bushing in a filament forming apparatus, the bushing having two laterally spaced apart banks of tips from which filaments are attenuated the method comprising the steps of:disposing adjacent the filament forming area an air housing having top walls and first and second side walls defining therebetween an air chamber, each of said side walls being oriented at an angle with respect to a vertical plane, said air housing positioned between the banks of tips, said first side wall including an opening, said opening facing the filament forming area beneath a first bank of tips; and inducing a first flow of air between the filament forming area beneath said first bank of tips and said air chamber to cool the filament forming area beneath said first bank of tips, said first flow of air having sufficient velocity to force air between the banks of tips into the filament forming area beneath said first bank of tips.
