ABSTRACT:
Filaments are extruded from polyolefin. A plurality of filaments are formed into a strand by twisting. The twisted strand is is twisted with other strands to form a rope which retains its tensile strength and reduces elongation. The filaments are made into strands before the heat introduced during extrusion has completely dissipated.
