Abstract
A method of coating an optical waveguide filament employing a sizing die having a tapered aperture terminating in a sizing orifice and a guide cone having a tapered outer wall terminating in a tip which is disposed adjacent said tapered aperture. The filament passes through an orifice in the tip of the guide cone and thereafter through the sizing die. The coating material flows into the channel formed between the tapered aperture and the tapered outer wall and contacts the filament in a region that is located between the guide cone tip and the sizing die orifice.
