Embodiment Construction

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings are for illustrative purposes and do not limit the scope of the invention. In the drawings, in order to avoid duplication of description, the same reference numerals are used to denote the same parts. The dimensional ratios in the drawings are not necessarily accurate.

[0014] figure 1 It is a schematic diagram showing an optical fiber winding method according to an embodiment of the present invention. The optical fiber winding device 10 has a shaft for setting the supply bobbin 11, a capstan 18, guide rollers 12, 14, 17, 19, 22, dancers 13, 21, and a shaft for setting the spool 23, and behind the capstan 18, The segment has a suction nozzle 20 as suction means. As the suction device, for example, when the optical fiber is disconnected or cut during rewinding, a device that sucks the optical fiber that is continuously supplied from the supply spool (the ...

Abstract

The present invention provides a winding method for an optical fiber, which abandons an abnormal part of the optical fiber without winding the abnormal part on a winding shaft, thereby realizing low cost. In the optical fiber winding method for winding the optical fiber (F1) obtained by drawing on the winding shaft (23), the abnormal part marked in the drawing process is not winded on the winding shaft (23), and the optical fiber is cut off in front of the abnormal part, and attraction is performed by an attractive nozzle (20) arranged at a back part of a winch (18), thus only the good parts in front / back of the abnormal part can be winded on the winding shaft (23).

Description

technical field [0001] The present invention relates to a method of winding an optical fiber on a bobbin, and to a method of removing an abnormal portion of the optical fiber when the optical fiber is wound on the bobbin. Background technique [0002] Generally, when an optical fiber is drawn from a glass base material, in order to protect the glass optical fiber, a sheath made of ultraviolet curable resin or the like is formed in one or two layers immediately after drawing. Then, rewinding or application of colored ink is performed. [0003] In the drawing process, the outer diameter of the glass optical fiber changes, or abnormal parts such as air bubbles are contained in the glass optical fiber or in the resin sheath, and in the long case, abnormal parts with a length of tens of kilometers may occur. JP 2005-97038 A describes a winding method when an abnormal part occurs. In this method, for example, when one abnormal part occurs, by (1) temporarily stopping the equipme...
