STEEL CORD FOR REINFORCING RUBBER MATERIAL
Document Type and Number:
Japanese Patent JP3805007
Kind Code:
B2
Abstract:
PURPOSE: To obtain steel cord of layer-twisted structure improved in wear resistance without inducing problem about safety, etc.
CONSTITUTION: This steel cord consists of a layer-twisted structure comprising an element wire having 0.15-0.25mm diameter and the number of the core element wires in the steel cord is 1-4. Layers more than one each comprising ≥6 sheath element wires and wound around the core element wire, and in the case the steel cord is curved so as to have a radius of curvature of a value of the formula: (d)/(17×10-3) in relation to a diameter (d) (mm) of an element wire in the most outside layer, maximum transferring amount of the element wire in the most outside layer in the cross section of the steel cord relative to its straight state is ≤(-0.5454(d)+0.1454)×103μm.
