CA 1294440

Abstract of the Disclosure A method and apparatus for producing hollow glass fibers is described in which the glass from a bushing tip and the gas used to provide a lumen in fibers as they are drawn from the tip are fed from passages in the tip sized to provide desired inside to outside diameter in the fibers drawn at the tip. This ratio is established inside of the tip by sizing the gas column having the tip and the glass column leaving the tip such that the ratio of the gas column to glass column is substantially the same ratio desired in the hollow fiber being drawn. Apparatus used to produce this ratio is also shown.
