Method of making glass fibers

摘要

A method of making feeder for supplying a plurality of streams of molten inorganic material to be attenuated into filaments is disclosed comprising inserting elements in apertures in a member; sealing said elements and member within a coating adapted to isostatically transmit pressure to said assembly; applying isostatic pressure to the hermetically sealed elements and member to mechanically join the elements to the member; joining the pressed member to other sections to form the feeder; installing the feeder at a fiber forming position to receive molten glass; and then energizing the feeder to fuse the elements to the member to prevent the unwanted passage of molten glass between said elements and said member, said elements having an orifice to permit the passage of molten glass therethrough to establish said streams.
