摘要 |
An optical fiber twisting apparatus that prevents line distortion in an optical fiber undergoing a drawing process and provides a consistent coating on a bare optical fiber. This optical fiber twisting apparatus includes a twist roller apparatus that having a twist roller that, by imparting a twist to an optical fiber, imparts a twist to a molten portion of an optical fiber preform positioned on an upstream side of the optical fiber, and a support portion that supports the twist roller.
