Abstract
An air nozzle apparatus for directing air flow against the undersurface of an orifice plate of a glass fiber drawing forehearth, having an air introducing section having a manifold formed with at least one air supply port, and an air nozzle section formed with a plurality of nozzle channels communicating with the manifold. The air nozzle section has a plurality of nozzle ribs of substantially the same shape each having opposed side surfaces and opposed end edge portions. The plurality of nozzle ribs are arranged to have their side surfaces located in adjacent relationship to provide a nozzle block. Each nozzle rib is formed on at least one of the opposed side surfaces with a longitudinally extending recess which defines one of the plurality of nozzle channels between the adjacent nozzle ribs.
