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.
Abstract:
This application relates to cable assemblies with an outer (exterior) layer formed from braiding materials together. To achieve a desired pattern, a machine tool forming the outer layer undergoes several modifications. For a machine tool with two tracks (e.g., inner and outer track) with multiple carriers of material to be braided, each carrier position may include multiple bobbins, with each bobbin carrying a spool/coil of the material. During a braiding operation performed by the machine tool, each track rotates in opposite directions. Moreover, some bobbins include an arm that guides the material in a particular manner. For example, during rotation of the track, the arm provides a swinging motion, causing the material carried by the arm to move in a periodic (e.g., sinusoidal) motion. An additional track may be used to guide the arms.
Abstract:
A yarn which contains a composite yarn composed of a core part containing a short fiber and a sheath part containing a synthetic fiber filament yarn, the core part and the sheath part being integrated via fluff of the short fiber getting between or entangled with the long fibers, the specific gravity of the yarn being adjustable in the range of 1.0 or more, a fishing line containing the yarn, and a method for producing the fishing line. The present invention provides an ideal fishing line which has a strong core-sheath structure, does not allow separation or detachment of the core part and the sheath part, is easy to handle, and also is excellent in strength, weatherability, and water resistance.

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.

Abstract:
A rope having a cut-resistant jacket which includes a core comprised of a plurality of sub-ropes. The sub-ropes may be in a parallel strand configuration. The sub-ropes and the strands thereof may be made of fibers of a synthetic material, such as polyester, nylon, polypropylene, polyethylene, aramids, or acrylics. A cut-resistant jacket surrounds the core and is made from a material that has increased strength and/or abrasion resistance over the material of the core. The cut-resistant jacket may comprise steel wires and may further comprise braided steel wires or rope. The braided steel wires or rope may be covered with a plastic material for increased corrosion resistance. A filter layer may be disposed between the core and the cut-resistant jacket and may be wrapped around an outer surface of the core prior to the cut-resistant jacket being formed.
