APARELHO E MÉTODO PARA COLORIR FIBRAS ÓPTICAS |
摘要 |
<p>A method of coloring optical fibers during the optical fiber drawing that includes the steps of feeding a natural fiber coating material and a colorant to a mixer; mixing the natural fiber coating material and the colorant in the mixer to obtain a colored coating material; and supplying the colored coating material to a coating die. The feeding step includes exerting on the natural fiber coating a first gas pressure variable with at least one fiber drawing parameter; and exerting on the colorant a second gas pressure variable with at least one fiber drawing parameter.</p> |
