Method of manufacturing an anchor element from a strand of twisted steel wire

摘要

A method and an arrangement for manufacturing an anchor element from a strand of steel wires by spreading outer wires of the strand apart from the central wire of the strand to form expanded sections. For spreading apart the outer wires, the strand is axially advanced through a rotatably mounted spreading disc provided with a number of openings corresponding to the number of wires, wherein each individual wire is passed through one of the openings. Following the spreading disc in advancing direction, spacer elements are mounted between the spread apart outer wires for fixing the outer wires in the spread apart position and forming the expanded sections. The spacer elements can be mounted in a continuous operation independently of the length of the strand and independently of whether the expanded sections ought to be provided over the entire length, or only a part of the length, of the anchor element.
