Claims

[Scope of utility model registration request]

An optical fiber coating device comprising a coating cup for storing a coating material, through which the optical fiber passes to coat the surface of the optical fiber, the end of the coating cup on the optical fiber exit side; a rubber cylindrical die having an optical fiber insertion hole communicating with the exit side end of the optical fiber, and compressing the rubber cylindrical die in the axial direction to adjust the hole diameter of the optical fiber insertion hole. A pressurizing mechanism is provided to adjust the diameter of the optical fiber insertion hole, and by tightening the diameter of the optical fiber insertion hole, the outer diameter of the coating of the optical fiber can be arbitrarily set. 1. A coating device for optical fiber, characterized in that it is capable of coating an optical fiber.
