Definitions

  • the present invention relates to ropes.
  • rope is meant an elongate member formed by twisting, laying, weaving or otherwise entwining a plurality of strands.
  • the invention provides a rope assembly comprising a plurality of ropes encased in a braided sheath, in which each rope is formed of at least two strands.
  • each sheath yarn is made of 4.4 lea staple which is spun at a twist of 3.0 turns per inch.
  • Each of the encased ropes forming the core is made of yarns which are based on ICI fibres Type 125 continuous filament polyester yarn.
  • the rope assembly of the embodiment has an average breaking load of 15.34 tonnes and a flex angle of 60°. The weight of the finished rope at check load is 41.6 kilogrammes per 100 metres.
  • the rope assembly has a stitch length of 80 millimetres at zero load, and of 84.6 millimetres at . check load.
  • the following table 1 sets out the data for 24 millimetre and 32 millimetre diameter rope assemblies constituting examples of the invention.
  • the encased ropes forming the core of rope assemblies of the invention can be based on a wide range of man-made, synthetic and natural fibres. Because the core ropes according to this invention are laid rather than twisted there is only a low variation of tension between the constituent yarns of each core rope. This method of construction is thus particularly suitable for constituent yarns having low extensibility such as organic polyamids.
  • the core ropes are constructed from "Aramid" organic polyamid yarns each covered with a polyester cover.
  • One example of such a yarn is that sold under the trade name Du Pont Kevlar PC.
  • the following table 2 sets out the data for 8mm and 24mm diameter rope assemblies constituting further examples of the invention.
  • the accompanying sketch illustrates one rope assembly of the invention; this assembly comprises four three-strand laid ropes 2 encased in a braided sheath 4.
  • the invention includes within its scope a rope assembly including two or more ropes encased in a braided sheath, and that each encased rope may be formed by entwining two or more strands.
