STRIP-SHAPED STEEL CORD |
摘要 |
A steel cord is obtained by bundling five steel core wires, which are arrayed in parallel with one another in a plane, into a unitary body by means of an adhesive having a thickness Ad of less than 15 μm. Each of the core wires-constituting the steel cord has a diameter d of less than 0.45 mm, and spacing Gd between the core wires is less than 20 μm. The core wires used have a free coil diameter D that is greater than wire diameter d thereof by 750 times or more. |

1. A strip-shaped steel cord in which multiple brass-plated steel core wires arrayed in parallel with one another are bundled with said parallel array being maintained intact, wherein:
a wire diameter of each of said core wires is less than 0.45 mm; the surface thereof is coated with an adhesive to a thickness of less than 15 μm and the multiple core wires are fixed together into a unitary body by said adhesive; a spacing between mutually adjacent core wires is less than 20 μm; and free coil diameter of each of said core wires is greater than the wire diameter by 750 times of more. |
