テイング装置。[Claims for Utility Model Registration] 1. In an optical fiber drawn out from an optical fiber spinning device whose wire diameter is controlled using the wire speed as a parameter, a resin is coated with a coating die, in which a change in the wire speed of the optical fiber is performed. Based on the output signal of this sensor, when the linear velocity decreases, the supply pressure of the resin to the coating die is reduced, and when the linear velocity increases, the pressure for supplying the resin to the coating die is reduced. An optical fiber coating apparatus comprising: a resin pressure control section that increases the pressure of supplying the resin to the coating die. 2. In a device that coats an optical fiber drawn out from an optical fiber spinning device whose wire diameter is controlled using the linear speed as a parameter with a coating die, a change in physical quantity accompanying a change in the linear speed of the optical fiber is detected. a sensor; and a resin viscosity control unit that lowers the viscosity of the resin when the linear velocity decreases and increases the viscosity of the resin when the linear velocity increases, based on the output signal of the sensor. An optical fiber coating device characterized by:
