METHOD OF WINDING UP SPACER FOR OPTICAL FIBER CABLE

摘要

PROBLEM TO BE SOLVED: To provide a winding method causing no rib deformation or torsion due to biting between spacers. SOLUTION: In the winding method, the spacer A for optical fiber cable is wound up on a bobbin B. The bobbin B is equipped with a cylindrical winding drum C and a pair of disk-like flanges D provided at both ends of this winding drum C. The spacer A is wound up in multi-layers on the outer circumference of the winding drum C while the bobbin B is rotated and traversed along the axial direction of the winding drum C. In this case, an inter-layer material E is interposed between the surface of the winding drum C and the winding front layer part. The inter-layer material E is a sheet-like material having a cushioning property and softness with a thickness of 0.4 mm or above and an apparent density of 0.3 g/cm3 or below. An interval between the laterally adjacent spacers A is set to be at least 0.1 mm or more.
