摘要：An optical fiber twisting apparatus that makes it possible to prevent theoccurrence of line distortion in an optical fiber as it is undergoing a drawing process andto provide a consistent coating on a bare optical fiber. This optical fiber twistingapparatus is provided with a twist roller apparatus that includes a twist roller that, byimparting a twist to an optical fiber, imparts a twist to a molten portion of an optical fiberpreform that is positioned on an upstream side of the optical fiber; and a support portionthat supports the twist roller. The accuracy of the outer circumference of the twist rollerwhen the twist roller is forming a part of the twist roller apparatus is 15 µm or less.
