ABSTRACT:
An apparatus for making reinforcing cages, the apparatus having: a frame; a former adapted to receive a plurality of longitudinally extending reinforcing rods; a bed attached to the frame, wherein the former rests on and is able to rotate relative to the bed; a drive for rotating the former; a loading module located adjacent to the former; a shuttle mounted on the loading module for longitudinal reciprocal movement towards and away from the former, wherein the shuttle feeds reinforcing rods into the former by moving towards the former, and withdraws the reinforcing rods from the former by moving away from the former as a reinforcing band is positioned around the reinforcing bars; and a rotatable cage holder adapted to hold a reinforcing cage during construction of the reinforcing cage, the cage holder being adapted to substantially prevent twisting of the reinforcing rods which form part of the reinforcing cage.
