ABSTRACT:
An improved method and apparatus for forming glass fibers is disclosed. The environment below the bushing is controlled by a pair of manifolds through which a cooling fluid flows. This cooling fluid additionally is employed to cool the various apparatus surrounding the bushing. The cooling fluid enters the manifolds through a plurality of entrance connections and exits the manifolds through a plurality of exit connections. The exit connections are connected to the various elements of the bushing apparatus and allows cooling fluid to flow through these elements. The cooling fluid is then returned to the manifolds by a separate set of entrance connections, flows through the manifolds, and again exits the manifolds through another set of exit connections to return to the fluid circulation system. Such a cooling system provides cooling to the environment directly surrounding and below the bushing and a systematic cooling fluid connection of the various elements surrounding the bushing which must be cooled in a glass fiber forming operation and thus connected to their source of cooling fluid.
