PURPOSE:To obtain the subject cord reducing thickness of cord and thickness of cloth layer due to the cord thickness by winding an outside flat filament on the periphery of plural inside filaments. CONSTITUTION:An outside flat 2 filament is wound in a spiral state on plural inside filaments 1 mutually parallel to each other so as to enclose the filaments with the flat filament. Wear is reduced and tensile strength, flexural rigidity and compression rigidity are increased. |
