ABSTRACT OF THE DISCLOSURE A pile extruder machine includes a hopper and a head or mandrel assembly extending from a support, into moulding chamber assembly. Feed augers are provided on each side of head or mandrel and these feed augers compress concrete from the hopper into the moulding cham- ber around the head or mandrel thus forming the pile and the compression moves the machine forwardly so that the pile is extruded rearwardly upon a pallet. A die assem- bly forms link of coil reinforcing around a coil support tube and the die assembly can be adjusted so that both the pitch and diameter of the lengths of coil can be adjusted. These coils are fed into the concerete mass at the base of the hopper and surround longitudinally extending reinforc- ing wires. They are drawn into the pile as it is formed and thus reinforce the piles circumferentially around the central aparature formed therein thus giving longitudinal and circumferential reinforcing to the finished pile.
