PURPOSE:To provide the title equipment ensuring fiber coils for optical sensor with specified performance to be stably obtained, designed to install a winding mechanism to wind optical fiber while twisting at a specified angle to its longer direction as the axis. CONSTITUTION:A delivery reel 11 with optical fiber A wound thereon is rotatably fitted on a frame 13 rotating around a revolving shaft 12. And the optical fiber A is wound on a rotationally driven take-up reel 10 in a stretched manner; during this process, the optical fiber A is twisted by rotating the delivery reel 11 around the revolving shaft 12 through rotating the frame 13. Furthermore, the frame 13 is designed to freely move in parallel with this paper surface, and corrections are made for the change in optical fiber position between the take-up reel 10 and delivery reel 11 developed as the winding proceeds, and the optical fiber A is wound on the take-up reel 10 while twisting at specified angle to its longer direction as the axis. |
