Method and apparatus for applying a sizing composition to glass fibers

摘要

A method and apparatus are provided for producing uniformly sized glass fibers. A heated bushing supplies streams of molten glass to be drawn into continuous fibers, and a drawing device attenuates the streams into fibers. A sizing applicator has a coating element engaging the drawn fibers, which applies a coating of sizing composition to the fibers. A shoe spaced from the applicator engages the fibers and causes the fibers to sweep back and forth across the element.
