Abstract
An apparatus (30) for cooling a lightguide fiber (21) drawn from a molten portion of a glass preform (22) located in a furnace (23). The apparatus (30) has an upper chamber (34) and a lower chamber (36) each having a small opening in the lower portions thereof. The upper chamber (34) has a heat transfer liquid (35) therein and the lower chamber (36) is pressurized to prevent liquid from passing through the opening. The hot fiber (21) is cooled by the liquid as it is drawn through liquid (35) without physical contact with the periphery of the openings.
