  • Apparatus and method for producing glass fibers
    Patent number: 5749933
    Abstract: In a method of making fibers in which molten glass is extruded through orifices in a bushing and cooled with cooling apparatus mounted below the bushing to form the fibers, it has been discovered that using new alloys containing a major amount of palladium and a minor amount of either iridium or nickel to make the cooling members or apparatus offers many advantages. Using semi-automatic welding to attach separate parts of the cooling members or apparatus minimizes porosity in the weld and increases service life.
