Abstract: In making synthetic rope or cable, a plurality of filaments are brought in parallelism into a core and compacted by a plurality of ribbons or tapes wound about the core under tension in opposite directions to form a uniform jacket that is torsionally stable. An outer sheath which may be urethane or other plastic material is applied to the jacket under sufficient pressure to penetrate the jacket but not the core, and then the urethane is cured. The rope or cable of the invention has a core of substantially parallel filaments free to move within the jacket of ribbons wound about the core and penetrated with the urethane or other plastic material. The method affords many advantages in speed of manufacture and cost, and provides a rope or cable of greater tensile strength and flexibility than other rope or cable constructions.

Abstract: A braided rope construction comprising a plurality of singles yarns twisted together to form a plurality of plied yarns which are then braided, with the helical angle of twist of the singles yarn within their respective plied yarn being equal and opposite to the helical angle of the plied yarns in the braid, whereby the singles yarns extend substantially parallel to the axis of said rope.
