Continuous filament rope and method of making same whereby high strength continuous synthetic filaments may be used to provide a rope which in use will have a strength approaching the theoretical strength of the fibers therein. The rope is made by combining a plurality of filaments and twisting the filament group into a light twine in comparison to the rope ultimately desired. The twine is then impregnated with a suitable flexible resin system and wound in a loop having at least a substantial number of turns of the twine. Thereafter the loop is allowed to twist back on itself in response to the twist initially set in the twine so as to form a rope-like center section with loops at each end thereof. Curing of the flexible resin system results in a suitable flexibility of the rope while providing for abrasion and fraying resistance. The loops at the end of the rope may be looped over hooks or pins when in use, with the resulting strength of the rope approaching that of the combined fiber strength. Lengths of rope may also be looped together to provide longer rope sections with only a small decrease in the resulting strength. The rope may also be woven into two dimensional configurations to form nets. Various methods of manufacturing are disclosed.

A method of making rope-like structures comprising the steps of:
A rope-like structure comprising a central section having a continuous loop at each end thereof formed of a substantial number of turns of twine, said twine being comprised of a substantial number of individual continuous filaments collectively twisted about the axis of said twine, said central section of said rope-like structure being twisted in a direction opposite the direction of twist in said twine, said rope-like structure having flexible a binder coating at least the outer fibers thereof.
A rope comprised of a plurality of rope-like structures, each having a central section having a continuous loop at each end thereof formed of a substantial number of turns of twine, said twine being comprised of a substantial number of individual continuous filaments collectively twisted about the axis of said twine, said central section of said rope-like structure being twisted in a direction opposite the direction of twist in said twine, said rope-like structure having a flexible binder coating at least the outer fibers thereof, said rope-like structures being looped together to form the rope having a length greater than that of the individual rope-like structures by an amount dependent on the number of rope-like structures looped together.
A multi-dimensional article comprising a plurality of rope-like structures, each having a central section having a continuous loop at each end thereof formed of a substantial number of turns of twine, said twine being comprised of a substantial number of individual continuous filaments collectively twisted about the axis of said twine, said central section of said rope-like structure being twisted in a direction opposite the direction of twist in said twine, said rope-like structure having a binder coating at least the outer fibers thereof the ends of said rope-like structures being looped together in a predetermined pattern to form the multi-dimensional article.
