Abstract:
Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.
Abstract:
One aspect of this invention concerns a multi-strand steel wire rope (28, 32, 36, 46, 50) comprising multiple strands (3, 10, 38) laid up helically on a core (30, 34, ), characterised in that at least some of the strands are deep strands (10, 38), i.e. strands with a heightwidth ratio greater than unity. Another aspect of the invention concerns the deep strand (10, 38) itself.
Abstract:
A metal cord (10 or 26) for reinforcing elastomeric articles, such as earth mover tires, comprises a plurality of metal wire-filament strands, including a center strand and multiple peripheral strands (14 through 24) concentrically surrounding the center strand. Each of the center and peripheral strands includes multiple individual wire filaments (26) of similar diameter having identical strand lay direction and length. Each strand has a hexagonally close-packed longitudinally uniform polygonal outline in which filaments are in concentric layers, with each individual filament being tangential to all adjacently surrounding filaments. The peripheral strands are tangential to the center strand and have a predetermined cord lay length and direction either the same as (Lang's Lay) or opposite to that of the center strand.

Abstract:
A cord for rubber reinforcement of the present invention includes a core strand including a plurality of strands (A), and a plurality of strands (B) disposed around the core strand. In the core strand, the plurality of strands (A) are finally twisted, and each of the plurality of strands (A) is formed of a plurality of reinforcing fibers (A) that are primarily twisted. Each of the plurality of strands (B) is formed of a plurality of reinforcing fibers (B) that are primarily twisted, and the plurality of strands (B) are finally twisted to be disposed around the core strand. The direction of final twist of the plurality of strands (B) is the same as the direction of primary twist in at least one strand (B) selected from the plurality of strands (B). The number of primary twists in the strand (B) is greater than the number of primary twists in the strand (A), and/or the number of final twists of the strands (B) is greater than the number of final twists of the strands (A).
