Abstract
PURPOSE: To prevent the foaming in the coating layer of an optical fiber, by circulating the coating material through a coating bath and a vacuum defoaming tank, and removing the bubbles generated in the coating bath with the vacuum defoaming tank.
CONSTITUTION: An optical fiber 5 is passed through the coating bath 7 from the inlet 7a to the outlet 7b, and coated with a coating material A. In that occasion, air is entrained with the moving optical fiber 5 into the bath 2 and dispersed by the flow of the coating material A. The coating material A containing bubbles is sent to a vacuum defoaming tank 9 through a line 15, and the defoamed material A' is introduced into the coating bath 7 through a line 16. The coating material in the bath is almost bubble-free, and the consequently, an optical fiber 5 having a bubble-free coating layer B can be obtained.
