Abstract: A multi-layer twisted strand or cable (1) comprising one central elongate element (11) surrounded by three layers of elongate elements, namely an inner layer, a middle layer and an outer layer.
Said elongate elements are wires or strands of twisted wires.
The surround elongate elements have several different sizes of area of transversal cross section thereof. The middle layer comprises elongate elements (12,14) of different size of area within the middle layer and the sizes of area of the elongate elements between the layers are different. The outer surround elongate elements (15) having the largest size of area. The outer surround elongate elements have a smoothened outer surface (152), so that the twisted strand or cable (1) has a smooth and satiny outer surface (152).
All surround elongate elements (13,12,14,15) having the same lay direction and the same pitch.
Elongation when stretch force is exerted on the twisted strand or cable and friction and abrasion caused by pulling the twisted strand or cable is reduced.

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.

Abstract: 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.
