ABSTRACT:
A high pressure glass fiber forming bushing and cooperating fin cooler assembly are disclosed. The bushing is provided with a corrugated tip plate which carries the nozzles or tips through which the glass fiber is forced by a pump or other pressure creating means. Additionally, the tip plate is provided with recesses which extend across the tip plate transversely to the corrugations. A cooperating fin cooler is secured beneath the tip plate to cool the filaments and to provide support for the tip plate. The fins of the fin cooler are arranged parallel to the corrugations in the tip plate. A plurality of ceramic rods are carried by the fin cooler and extend transversely to the fins and coincident with the recesses in the tip plate. These ceramic rods are received in the recesses to provide support for the tip plate.
