Abstract
An object of the present invention is to effectively reduce mixing of bubbles into a spun glass fiber. A glass-melting devicefor producing glass fibers includes; a first glass-melting tankexposed to a reduced-pressure atmosphere; a second glass-melting tankand a third glass-melting tankarranged below the first glass-melting tank; an ascending conduitthat sends up molten glass resulting from melting in the second glass-melting tankto deliver the molten glass to the first glass-melting tank; a descending conduitthat sends the molten glass down from the first glass-melting tankto deliver the molten glass to the third glass-melting tank; a decompression housing; and a bushing. The glass-melting devicefurther includes heating means for separately heating the first glass-melting tank, the second glass-melting tank, the third glass-melting tank, the ascending conduit, the descending conduitand the bushing
