Claims
- 1. In an electromechanical cable, a composite strain member comprising:
- a plurality of fibers having high tensile strength and slick surfaces disposed in adjacent parallel relationship to form a bundle; and
- a jacket of plastic material enclosing said bundle;
- the cross-sectional configuration of said composite member being easily deformable, and said jacket serving to confine said fibers in a predetermined lateral position while said fibers may slide longitudinally relative to each other and within said jacket as required by mechanical movements of the cable.
- 2. In an electromechanical cable, a composite strain member comprising:
- a plurality of fibers of high tensile strength disposed in side-by-side relationship to form a bundle;
- lubricating means on the surface of said bundle; and
- a plastic jacket enclosing said bundle and lubricating means;
- said bundle being longitudinally slidable within said jacket.
- 3. A strain member as in claim 1 which is deformed to have a substantially rectangular cross-sectional configuration.
- 4. A strain member as in claim 1 wherein said fibers are made of aramid.
- 5. In an electromechanical cable, a plurality of strain members arranged in a circumferential layer, each of said strain members including a bundle of yarns of high tensile strength and a plastic jacket surrounding said bundle, each of said bundle of yarns being longitudinally slidable within the corresponding jacket, the plastic jackets of adjacent ones of said strain members being bonded together.
