    Abstract: Disclosed is a method of forming corrosion protection coatings on prestressing strands. It comprises the steps of untwisting sequential lengths of a prestressing strand; keeping the surrounding steel wires apart from the core steel wire to coat these steel wires with a synthetic resin; and twisting the coated steel wires to provide a prestressing strand of the original shape, thus permitting the separate coating of each steel wire, leaving, on the prestressing strand surface, the helical dent as deep and wide as the noncoated prestressing strand to assure the bond of the twisted wire to the surrounding concrete as firm as the noncoated prestressing strand. Also, an apparatus for carrying out such coating method is disclosed.

    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.
