ABSTRACT:
A composite reinforcing rope is made of a cylindrical core of twisted filaments of aromatic polyamides around which a plurality of steel wires of a rectangular configuration are coiled. The steel wires are wound side-by-side in one layer. Each wire is twisted around its own axis to such a degree that its broader side fully engages the periphery of the polyamide core. The edges of respective wires are rounded whereby the convex narrow dides of adjoining wires contact one another substantially along a line.
