    Abstract: Elevator coated ropes or belts are disclosed. The coated rope or belt may include at least one cord and a jacket retaining the at least one cord. The cord may include a plurality of filaments. The filaments are free of second-order helical structure. In a first embodiment, the filaments includes at least one inner filament and a plurality of outer filaments surrounding the at least one inner filament. The outer filaments are bunched together by forming a first-order helical structure through the length of the cord. In a second general embodiment, the filaments are free of both first- and second-order helical structures. The filaments are bunched together by a restraining loop or adhesive at one or more locations along the length of the cord. Methods of making the tension cord are also disclosed.

    Abstract: A steel cord for reinforcing a rubber article which can improve the cut resistant property in the case of treading on an obtusely or sharply pointed projection without decreasing the strength in the axial direction of the cord and without increasing the tire weight, as well as a tire utilizing the same as a reinforcing material, are provided.The steel cord for reinforcing a rubber article has a multi-twisted structure formed by twisting a plurality of sheath strands (2) formed by twisting a plurality of wires around a core strand (2) formed by twisting a plurality of wires, and the core strand (1) and the sheath strands (2) are constituted of an at least 2-layer-twisted structure formed by twisting core wires and sheath wires respectively. In this case the relationship represented by the following formula 1.8≦[(S·cos2α)/{r·(φ1+φ2)}]×100≦4.2 is satisfied, wherein φ1: the diameter of an outermost wire of the strand (1), φ2: the diameter of an outermost wire of the strand (2), r: the center distance between the strand (1) and the strand (2), S: the cross section of the strand (2), and α: the twist angle of the strand (2).

    Abstract: Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member.In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together. In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.
