PURPOSE: A manufacturing method of round slings is provided to prevent accidents when a breaking rate determined about using load of a loading material occurs and to increase life span of the round slings. CONSTITUTION: A manufacturing method of round slings includes the following steps: twining several strands of yarns(S11); coating the twined cores with conductive pigment(S12); drying the coated cores(S13); inserting the coated cores into an elastic core tube(S14); preparing a processing condition to shape the molded core(S15); connecting one ends of the core(S17); aligning the core tube inside the outer cover tube(S18); and swing both ends of the outer tube(S19).
