Abstract

A corrosion resistant rope in which the individual strands are sealed with a plastic foam impregnant and surrounded with a dense unfoamed plastic material is made by applying a foamable plastic to the individual wires of a series of wire strands, or, alternatively, to the individual strands as a whole, and closing the strands into a rope in a closing die while passing a nonfoamable plastic material into the closing die. Sealed plastic foam impregnated wire strands can be made in the same manner by passing nonfoamable plastic material into the stranding die during fabrication of the strand.
