Abstract
A rope has a braided sheath that includes a spiraling strand having a greater pitch in comparison with a pitch exhibited by other strands of a coverbraid that encloses that rope's strength member core. The rope is useful for forming pelagic trawl mesh, and is stronger for a given amount of material, has less drag, and exhibits the same or bettered lift when towed through water at trawl mesh angles of attack. The rope also is less costly to manufacture in comparison to known helix rope costructions.
Claims25
An improved rope (35) for forming portions of a trawl, the rope including at least one strength member (37), at least a braided sheath (398) formed about and enclosing the strength member (37), and at least one spiraling strand (36) included among strands (397) forming the braided sheath (398), where such spiraling strand (36) is larger in diameter than other strands (397) forming at least portions of the braided sheath (398), the rope characterized by the spiraling strand (36) having a braid angle (406) that is less than a braid angle (407) of other strands (397).
