Abstract
An optical fiber resin coating device having a nipple and a die which each have gradually tapering holes through which the optical fiber is drawn. The die and the nipple have adjacent parallel flat surfaces which are spaced to created a gap through which resin is supplied by pressuring to be applied to the optical fiber. The gap between the die and the nipple and the tapered holes within the die and the nipple are all designed to produce a resin coating which is even and contains no air bubbles, especially at high optical fiber drawing rates.
