Method and apparatus for providing controlled quench in the manufacture of fiber glass
Abstract
Abstract Disclosed herein are methods and apparatus for controlling the quench of glass fibers as they are extruded. A fluid, such as air, is caused to flow evenly with controlled impingement at the roots of fibers as they are being extruded from a bushing, and/or a controlled temperature environment is provided along the extruding cone of fibers. With either or both approaches small fibers with greatly reduced breakage can be produced. Several embodiments of the present concepts are disclosed wherein a manifold device is used at the bushing to provide a controlled even flow of air at the roots of the extruding fibers, and wherein a chamber may be used along a length of the drawn fibers to provide a controlled environment and to reduce the stress in such fibers during attenuation.
