Abstract
Abstract A method of making a tapered wedge for use in gripping a multi-ply rope or cable, especially concrete-reinforcing tendons, wherein the tapered wedge is circumferentially divided into a plurality of parts surrounding an axial aperture for the rope or cable. Each of these parts is deformed, for at least a part of its axial length, by pressing only its circumferential side edges inwardly toward the axis of the aperture so as to displace its interior surface adjacent these edges inwardly as well as to displace exterior surface regions inwardly.
