摘要：<p>A method and arrangement for manufacturing an anchor element 1, Fig 1a, from a strand 2 of steel wires 3 comprises spreading outer wires 3b, Fig 2a, of the strand apart from the central wire 3a to form expanded sections 4. For spreading apart the outer wires, the strand is axially advanced through a rotatably-mounted spreading disc 12 provided with a number of openings corresponding to the number of wires, wherein each individual wire is passed through one opening. Following the spreading disc 12 in the advancing direction spacer elements 5 are mounted between the spread outer wires for fixing the outer wires in the spread position and forming the expanded sections. The spacer elements 5 can be mounted in a continuous operation independently of the length of the strand 2 and independently of whether the expanded sections are provided over the entire length, or only a part of the length, of the anchor element. <IMAGE></p>
