    • A method and apparatus for coating optical transmission glass fibers with a resinous composition. A vessel is provided through which a glass fiber is drawn. While it is being drawn through the vessel, the fiber is spun, and a resin coating is applied. In order to maintain the air pressure within the vessel fairly constant, an exhaust vent is provided through which excess particles of the resinous composition may escape. Turbulence is thus substantially reduced preventing the fiber from swinging and allowing the particles to be sprayed smoothly. Further, the particles may be electrically charged so that they are both attracted to the optical fiber and repel one another during flight. The invention employs both of these features to produce a uniform coat on an optical transmission glass fiber.
    • 一种用树脂组合物涂覆光学透射玻璃纤维的方法和装置。 提供容器,通过该容器拉出玻璃纤维。 当它被吸收通过容器时,纤维被纺丝,并施加树脂涂层。 为了保持容器内的空气压力相当恒定,提供排气口,通过该排气口,树脂组合物的多余颗粒可以逸出。 因此,湍流显着减少,防止纤维摆动并允许颗粒平滑喷射。 此外,颗粒可以带电,使得它们都被吸引到光纤并在飞行中彼此排斥。 本发明使用这两个特征来在光学透射玻璃纤维上产生均匀的涂层。
