Abstract

A method of manufacturing an anchor element for a soil anchor or rock anchor, rock bolt or the like, from a strand of twisted steel wire. The anchor element includes a central wire and outer wires arranged radially relative to the central wire. The anchor element has at least one expanded section obtained by spreading the individual wires. Spacer members are provided for fixing the individual wires in the spread-apart position. The central wire is laterally deflected when the individual wires of the strand are being spread and, by inserting a rod-shaped spacer element, the central wire is fixed in an out of center position together with at least one outer wire.
