  • Publication number: 20230332351
    Abstract: Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope, comprising multiple layers of twisted and braided yarns, wherein individual sheaths enclosing individual strands are of a material such as HMPE, PTFE or UHMWPE with a lower decomposition temperature than the material of said strands being aramid, the method comprising subjecting parts of the rope to heat and tension thereby pre-stretching and creating a non-uniform or non-round shape of said strands, further choosing a combination of braid and twist angles as well as braid compressive forces to accommodate specific strength and elongation relation between the individual rope layers.

  • Patent number: 11525212
    Abstract: A production method for a headline sonar cable characterized by steps of: a. providing a first strength member (14); b. coupling to strength member (14) a conductor (122); c. forming a layer of polymeric material about the combination of strength member (14) and conductor (122) while ensuring that the conductor remains slack; d. forming a flow shield around the layer of polymeric material, thus forming an elongatable internally located conductive structure; and e. braiding a strength-member jacket layer (52) of polymeric material around the elongatable internally located conductive structure while ensuring that the conductor is slack when surrounded by the jacket layer (52). For another embodiment, an optical fibre is wrapped around the exterior of the layer of polymeric material within which is enclosed a braided conductor formed about the first strength member (14). Other embodiments employ further thermo-plastic layers and further sheaths and further conductors.

  • Patent number: 9704617
    Abstract: A production method for a headline sonar cable (20, 120) that exhibits a high breaking-strength and lighter weight than a conventional steel headline sonar cable. Producing the headline sonar cable (20, 120) is characterized by the steps of: a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34, 134) is slack when surrounded by the jacket layer (52). The structure (34, 134) of the cable (20, 120) retains conductivity upon stretching of the jacket layer (52) surrounding the structure (34, 134) that lengthens the cable (20, 120). For one embodiment of the method a conductor (20) wrapped around a rod (24) and enclosed within a sheath layer (32) forms the structure (34, 134).

  • Publication number: 20160258089
    Abstract: A method for producing a rope (35) that is useful for forming pelagic trawl mesh, particularly self-spreading trawl mesh. The rope (35): 1. is stronger for a given amount of material; 2. has less drag; 3. exhibits the same. or better lift when subjected to water flow at trawl mesh angles of attack; and 4. is also less costly to manufacture in comparison with known helix rope constructions. Most broadly, the method and apparatus of the present disclosure include a standard braiding apparatus (11) where an additional planetary carrier apparatus orbits about the outside of the usual planetary carrier apparatus, at a same or similar height as the usual planetary carrier apparatus, at a lower speed than the usual planetary carrier apparatus, and preferably carries fewer bobbins (19) than the usual planetary carrier apparatus.
