Abstract

PURPOSE: To coat an optical fiber with a laminar coating layer with a simple apparatus, by dividing a coating bath into inner tank and an outer tank each having a die, arranging the inner tank die at the outlet of the coating bath and concentrically with and inside of the outer tank die, and supplying the outer tank die with the raw material under pressure.
CONSTITUTION: A spun optical fiber 3 is introduced into a coating bath 5, passed through the concentrically arranged die 4a of the inner tank 5a, and the die 4b of the outer tank 5b, and coated with a double layered coating film composed of the coating film 7a of the coating material 9a and the coating film 7b of the coating material 9b. When the diameter of the die 4b is made equal to or smaller than that of the die 4a, the introduction of the optical fiber 3 through the die can be facilitated, and the coating films 7a and 7b are densified.
