Abstract
PURPOSE: To enable formation of a coat corresponding to an increased linear velocity of an optical fiber by passing the fiber through a coating material container while maintaining the external pressure of the container near the outlet lower than the internal pressure.
CONSTITUTION: Naked optical fiber F running at a high velocity after spinning is successively passed through material container 1 filled with liq. coating material A, pressure vessel 6, outside diameter measuring means 8 and heating furnace 9 to form coat A' made of material A around fiber F. At this time, the interior of container 1 is under atmospheric pressure, and the internal pressure of vessel 6 is set lower than that of container 1 with vacuum pump 7. Accordingly, even if fiber F is running at a high linear velocity, material A at outlet portion 3 is provided with such higher speed fluidity that material A attaches to the surface of fiber F and can follow it, and coat A' is formed on the surface of fiber F without a coating break.
