BOBBIN FOR WINDING LINEAR BODY

摘要

PROBLEM TO BE SOLVED: To wind a plurality of kinds of linear bodies such as optical fiber around a barrel part of a bobbin for winding linear body even when a ratio of length of respective linear bodies is changed. SOLUTION: In this bobbin for winding linear body having a cylindrical barrel part 2 and two disc-like collar parts 1 provided at both ends of the barrel part, two kinds or more of linear bodies such as optical fiber can be wound around one bobbin even when a ratio of length of respective linear bodies is a changed by providing partitioning discs 3a, 3b which can move in the axial direction of the barrel part 2 and are parallel with the collar parts 1 on the barrel part 2 to fix them at arbitrary positions in the axial direction on the barrel part 2 by a tightening member 4.
