MANUFACTURE METHOD AND APPARATUS FOR IMPROVED EFFICIENCY REDUCED COST ROPE FOR PELAGIC TRAWLS

摘要

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; and4. 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.

主权项

1. A braiding apparatus capable of forming a braided sheath about a central core, the braiding apparatus having both a support member and at least a first planetary carrier apparatus that has:
a) a series of drivers carried by the support member and arranged so as to encircle an imaginary axis line (20) passing through a braiding point; b) a mechanism to rotate adjacent of said drivers in opposite directions; a plurality of cars, each car capable of
i. carrying a quantity of a strand; andii. being driven by the driver for travel in serpentine intersecting paths in opposite directions around the imaginary axis line (20),the braiding apparatus also having a second planetary carrier apparatus, the braiding apparatus characterized by the fact that the second planetary carrier apparatus includes a track (14) and a reverse curved track portion (24) that are sitioned at a height that is above a height that is positioned the first planetary carrier apparatus.
