A demountable wire carrier (100) is for supporting loops of wire W and comprises a lower end-stop (110), an upper end-stop (120) and a plurality of frame members (130) extending between (10) the end-stops. The carrier is shown standing inside a cylindrical loop-forming container (140) into which the wire W has been fed in the direction of Arrow A, so that the wire forms loops around the inside of the container wall. The introduction of the wire takes place when, prior to assembly of the carrier, only the lower end-stop (110) is positioned inside the container, so that the loops of wire rest on the lower end-stop (110). After all the wire has been introduced into the container (140), the frame members are connected to the lower end-stop, and the upper end stop is then connected to the frame members to complete assembly of the carrier.
