ABSTRACT:
A spool for wires or cords made of metal, plastic or the like, and particularly welding wires. It has single-piece segments, each forming a U-shaped support yoke with a cross bridge and legs. This yoke extends inwardly in radial planes, its free leg ends having the extensions extending in the circumferential direction, and the extensions, joined together, form two parallel wire rings. Two symmetric wire parts are fastened on the radial legs for forming a hub on both sides of the segment, whereby a wire part on both sides of the hub ring segment has a part with a bent extension leg. This part extends the legs against the spool center and reaches up to the spool diameter. In their transition zone into the hub ring segments, the wire parts are connected with each other, whereby the plane established by the connected wire parts coincides with the plane established by the wire rings and the legs.
