ABSTRACT:
A process and apparatus for forming fibers from attenuable materials, such as molten glass, by attenuating streams of glass from the bottom of a bushing wherein the bottom has downwardly presented wall portions at upper and lower levels. According to the disclosure the upper and lower wall portions are formed into series of elongated channels, separated by grooves in the underside of the bushing. Filamentary material is manufactured by drawing at least one filament from each of a plurality of orifices formed in spaced rows in the bottom walls of the channels. Temperature differences existing in the molten material within the bushing are evened out by differential cooling of the material as it flows through the channels to the orifices. Cooling is effected in various ways including the placement of solid elongated cooling fins underneath the grooves between channels.
