    Abstract: To improve a tensile strength without impairing flexibility and adhesion strength to concrete, and to form thick coating in a surface layer part for preventing a basis material from being exposed by a damage of the coating, a method of forming double coatings on a prestressing strand includes a primary painting process after a pre-treatment process, in which a resin coating is formed only in the surface layer, a secondary painting process in which respectively individual state resin coating is formed on outer peripheral face of each of the core wire and the surrounding wires under a loosened and separated state, thereby forming a double coating in each surrounding wire, and a finishing process of tightening and retwisting the surrounding wires about the core wire to an original state. The obtained prestressing strand has the double coating portions only in the surface layer thereof and enough flexibility and adhesion strength to concrete.

    Abstract: The present invention is directed to bead wires which has a Cu/Sn deposit having an Sn content of 9 to 13% by weight and a Cu content of 91 to 87% by weight, in an amount of 0.65 to 0.85 g per kilogram of the wire. The present invention is also directed to rubber-coated bead wires for tires comprising the plated bead wire as mentioned above, a rubber layer formed on the bead wire from a composition comprising 100 parts of a rubber polymer, 80 to 140 parts of a carbon, 4 to 10 parts of sulfur, 0.4 to 0.9 part of a vulcanization accelerator, 10 to 7 parts of zinc oxide, and 1 to 4 parts of stearic acid, and to tires prepared by using the above-mentioned bead wires. The bead wires of the present invention have excellent adhesion between the plated bead wire and the rubber layer, so that the tires obtained using such bead wires avoid wild wires.
