APPARATUS FOR PRODUCING GLASS FIBERS

摘要

An improved fin cooler structure for use in apparatus for the production of continuous glass filaments attenuated from streams of glass flowing through orifices in a stream feeder comprising elongated members or fins of a non-ferrous metal disposed in heat-transferring relation with the streams of glass fibers thereby to absorb and convey away heat from cones of glass formed by the glass flowing through the orifices to rapidly cool the glass of the streams as well as to stabilize the environment by isolating the cones of glass from atmospheric air currents. The fin cooler structure is formed of a single sheet of material by cutting the fin members in a portion of a flat sheet of material and rolling the uncut portion of the sheet to form a tubular member through which heat conducting fluid, such as water, may be passed to increase the heat absorbing efficiency of the fin cooler structure.
