Abstract
An apparatus for applying a coating on a lightguide fiber (60). The apparatus is comprised of a container (10) having the coating die (18) in the bottom portion thereof and a plurality of separating means (26--26) therein which divides the container into an upper chamber (12), a lower chamber (16) and at least one chamber (14) intermediate to the upper and lower chambers. Each separating means (26) is sealed to the inner surface of the container (10) at the outer edge portion and has a small, centrally located aperture (28) which is vertically aligned with the apertures in the other separating means and the coating die (18). Additionally, a means is provided for directing coating material (40), under pressure, into the lower chamber (16).
