ABSTRACT:
A metallic reinforcing cord structure suitable for reinforcing elastomeric articles characterized by a high compression modulus which increases resistence to buckling and fatigue failure and by improved adherence between the core and the elastomeric article in which it is embedded is disclosed. The cord comprises a core consisting of two equal diameter brass plated steel wires and an outer layer of six equal diameter brass plated steel wires disposed about the core wires, the diameter of the outer layer wires being between about 1.23 and about 1.43 times the diameter of the core wires. The two core wires are twisted about one another and the outer wires are twisted about the core. Both the core and the outer wires are laid in the same direction.
This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and the extent of the invention being discernible only by reference to and from the entire disclosure.
