Claims

[Claims for Utility Model Registration] (1) Adjacent windings of copper alloy plated steel wire with a diameter of 0.5 to 2.0 mm coated with a rubber composition to a thickness of 0.05 to 0.25 mm are connected to each other. It is made up of multiple layers of wire wound in a cylindrical coil shape in close contact with each other.
At least the plurality of winding layers in the central part, excluding the inner and outer 1 to 3 winding layers, are stacked with n winding layers with the same number of steel wire turns, or with n winding layers with the same number of steel wire turns. A bead ring for a pneumatic tire consisting of alternately laminated layers of 1 and 1 turns of winding. (2) The arrangement of the steel wires in each winding layer of the plurality of winding layers in the central portion is shifted by 1/2 the pitch of the windings between adjacent layers so that the steel wires are packed most densely. Arranged bead rings according to claim 1 of the utility model registration claim. (3) A claim for utility model registration in which the plurality of winding layers in the central part consist of the same number of turns of steel wire, and the steel wires in each winding layer in the central part are arranged in an orthogonal grid pattern in cross section. The bead ring described in Range 1. (4) Utility model registration claim No. 1 in which the number of turns of steel wire is sequentially reduced by one, rather than each of 1 to 3 inner or outer winding layers being adjacent to the center side. Bead ring as described in section. (5) A claim for utility model registration in which all the winding layers, including the innermost layer and the outermost layer, consist of the same number of turns of steel wire, and the entire steel wire is arranged in a cross-section in an orthogonal grid pattern. The bead ring described in item 3. (6) The rubber composition is one or more rubbers selected from natural rubber and diene-based synthetic rubber.
Carbon black 70-100% by weight
The bead ring according to claim 1, which is a utility model, and comprises a composition containing 5 to 20 parts by weight of sulfur, 5 to 20 parts by weight of silica, and 5 to 15 parts by weight of silica.
