摘要： 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.

摘要： The present invention provides structure of steel cord in heavy duty tires, in which the adhesive strength between filament and rubber, and penetrating property of rubber are improved by making the twist direction of core and strand different in the steel cord comprising core and strand filament, and by making the pitch or the twist period of core and strand different. In particular, this structure is applied to steel cord of 3+8*d(HT) which is used in heavy duty tires. In this application, twist direction of core filament is in the S direction and twist direction of strand filament is in the Z direction, and the ratio of the pitch of core filament (CP) and the pitch of strand filament (SP) is between 0.50 and 0.94.

摘要： The present invention relates to a steel cord, for reinforcing rubber articles, of the '3 + 6' type, specifically three core wires and six crown wires. All the core wires and crown wires have the same diameter of between 0.30 mm and 0.40 mm, in particular equal to 0.35 mm. Preferably the core wires and the crown wires are in HT steel. The cords are enclosed in a ply with a density of between 40 cords/dm and 50 cords/dm. In particular the ply forms at least one of the metallic reinforcing layers present in at least one belt layer of a tyre.
