ABSTRACT:
A termination and method of terminating braided ropes or cables of aramid fiber includes fabricating short tapered reinforcement ropes of the same material which are inserted at each end of each rope to increase its thickness, forming a collar having a tapered interior channel and a tube to fit inside the channel having a tapered outside surface. The reinforced rope ends (four, in this example) are tied off near their ends, separated into individual fibers, and any coating thereon washed out. These ends are then dipped into a suitable resin potting compound. A centering tool is inserted through the bore of the tube and used to pull the tube tightly into the interior of the collar, thereby compressing the ropes including the resin-coated ends tightly between the collar and the tube. The resin is then cured. Where it is desired to terminate both ends, the ropes initially terminated are doubled to leave loops at the opposite end. These loops are assembled onto pulleys and tensioned a number of times to equalize the lengths of the ropes. The four ropes then resulting are cut to equal lengths, and the second end is terminated as set forth above.
