Abstract: A steel cord, for use in the reinforcement of resilient articles such as rubber tires, comprises a central bundle of wires surrounded by a circumferential layer of helicoidally twisted wires. In the central bundle, one can distinguish a core and a surrounding layer, the latter having the same twist pitch as the circumferential layer. In order to reduce wire migration, the wires of the central bundle show a limited number of relative position changes, between 2 and 300 per 30 cm cord length.

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.

Abstract: A compact steel cord is provided. The cord includes a core-filament I steel wire with a diameter of d0, and four middle-layer M steel wires with a diameter of d1 and eight outer-layer O steel wires with a diameter of d2 that are twisted around the core-filament I steel wire in the same lay direction and the same lay length. Gaps L are reserved between the outer-layer O steel wires, an average width of the gaps L is not smaller than 0.02 mm, and the total size of the gaps L is larger than d0 and smaller than d1. The steel cord of a stable structure can be obtained by controlling the proportion of the sizes of all layers of monofilaments, the rubber coating performance of a tire cord can also be improved, the corrosion resistance, fatigue resistance, impact resistance and adhesion retention of a tire are improved.
