ANNULAR CONCENTRIC STRANDED BEAD CORD AND METHOD FOR PRODUCING SAME |
摘要 |
An object of the present invention is to impart long-lasting, stable corrosion resistance to an annular core of an annular concentric-lay bead cord at a low cost. Corrosion-resistant coating is provided on the surface of the steel wire forming the annular core 1 to cover the surface of the steel wire with a thick coating film 3, thereby preventing exposure of the surface of steel wire even if fretting develops between the annular core 1 and the wrap wire 2. With this arrangement, it is possible to impart long-term, stable corrosion resistance to the annular core 1 at a low cost. |
