ABSTRACT:
The present invention relates to a method of continuously impregnating and encapsulating a wire rope with a liquid polymer formed from at least two reactive components which when mixed and heated together react chemically to form the polymer. In accordance with a preferred embodiment of the invention, the components are separately pumped into a mixer and then into an injection die, and a preheated wire rope is passed through the injection die. The wire rope is preheated to a temperature sufficient to initiate reaction of the components. The reaction of the components forms the liquid polymer which continuously flows into the voids or spaces of the wire rope and encapsulates the outer surface of the wire rope. The liquid polymer cures in and around the wire rope to form a unitary impregnated and encapsulated wire rope.
