    Abstract: A torque coil (two-layer coil structure) of the disclosed embodiments includes an inner coil formed by spirally winding metal wire, and an outer coil arranged to be in close contact with the outer periphery of the inner coil and formed by spirally winding metal wire. A winding direction of the inner coil and a winding direction of the outer coil are opposite from each other, and when the torque coil is twisted in the circumferential direction in which the diameter of the inner coil is increased, a change amount of the diameter of the outer coil is larger than a change amount of the diameter of the inner coil. The two-layer coil structure has high twisting rigidity, thus suppressing the occurrence of kinks due to rotational resistance.

    Abstract: An elevator rope comprising an elastomer coated, multistrand steel wire cable is claimed. In such a cable strands have a lay-length of at least 6.5 times the diameter of the bare cable diameter D. The cable is further coated with an elastomeric jacket, which adheres to the strands with a pull-out force not less than 15×D+15 newton per mm. The advantages of such an elevator rope are amongst others its limited elongation, its reduced diameter and its improved fatigue life.

    Abstract: In a tire the strength of steel cord and the resilience of rubber are a successful combination. However, in some specific areas of a tire, more elongation is expected from the steel cord, while still a sufficient degree of stiffness is expected. A steel cord is presented that has these properties. The steel cord comprises two or more steel elements that are twisted together. The steel elements comprise one or more steel filaments. In total the steel cord comprises ‘N’ filaments, each with a cross sectional area ‘A’. When the steel elements are individualised out of the steel cord they show a helix pitch length of ‘Lo’, while a single pitch has a centre line length of ‘S’. The inventive steel cord shows a ‘P’ value of at least 50 newton, wherein P=πNE (A/S)2. Further methods are presented to produce this steel cord.

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).
