Method of making a mechanical cable
First Claim
1. A method of making a mechanical cable comprising:
- a) applying a surrounding layer of fluoropolymer adhesive to a steel wire core;
b) helically wrapping a tape about the surrounding layer of fluoropolymer adhesive, said tape comprising porous polytetrafluoroethylene; and
c) applying heat adequate to melt the surrounding layer of fluoropolymer adhesive, thereby causing the tape to adhere to the steel wire core.

Abstract
A method of making a mechanical cable having a steel wire core, a layer of fluoropolymer adhesive covering the steel wire core, and an outer layer of porous PTFE covering the layer of fluoropolymer adhesive. The mechanical cable may be a component of a mechanical cable system wherein the mechanical cable slides axially or rotates within a surrounding support tube. The support tube preferably has an inner surface comprised of non-porous PTFE. The support tube may optionally incorporate a contamination seal at the ends of the support tube to reduce the entrance of contaminating dirt and water into the system. The layer of porous PTFE covering the steel wire core may optionally be filled with a lubricating and abrasion resistant filler such as graphite.
