    Abstract: The cable consists of a core part and of outer wires (2) twisted around the core part. The core part consists of two wires (1) twisted around each other, the section of the said wires being based on a circle, or of one wire (3) twisted around its own axis and having a flattened section. The direction of twisting of the core part (1 or 3) is opposite to the direction of twisting of the outer wires (2).

    Abstract: A steel cord (10) adapted for the reinforcement of rubber products, comprises a core strand (12) and six peripheral strands (14) concentrically surrounding the core strand (12). Each of the core and peripheral strands (12, 14) comprises a centre of two or more centre filaments (16) and two layers of filaments surrounding the centre. The core strand (12) has a diameter D1 which is greater than the diameter D2 of the peripheral strands (14). All the filaments (18, 20) of each layer have substantially the same diameter and a radially outer layer has a twist angle which is greater than a twist angle of a radially inner layer of the same strand. Each of the strands (12, 14) in the cord is composed of no more than twenty-six filaments (16, 18, 20) being twisted together.
