Abstract: 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.

Abstract: Continuous filament apex fittings and methods of manufacture thereof to provide high-strength, low-weight fittings for use on cargo lifts and the like, and as replacements for metal clevises. The fittings are made by wet-winding one or more strands of continuous filaments into a loop, forming the loop into a basic clevis-like shape and curing the resin. The use of a flexible resin allows spreading of the clevis eyes for entry and removal of the item to be retained by the clevis without a separate clevis pin. Twisting of the loop one or more times along the major length of the loop prior to bending in the basic clevis shape creates an integrated clevis body having better load distribution across the cross-section thereof. Alternate methods of manufacture are disclosed.
