US 10,710,143 B2 · Controlled translation method of affixing a termination to a multi-stranded tensile member

Abstract

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

Dependent claims

A method for adding a termination to an end of a tensile strength member including multiple synthetic filaments, said tensile strength member having a central axis, comprising:

(a) providing an anchor with a cavity;
(b) providing a potting compound in a liquid state, said potting compound being configured to transition to a solid state;
(c) placing a length of said filaments within said cavity;
(d) adding said potting compound in said liquid state to said cavity;
and
(e) while at least a portion of said potting compound remains in said liquid state, applying tension to said tensile strength member.
