Abstract
Apparatus for forming a non-rotating helix of metal strip. The apparatus includes a store for the strip rotatable about the axis of the helix. The store has a radially inwardly facing circumferential opening from which the strip is withdrawn by guide shoes which are also rotatable about the axis of the helix but at a different rotational speed to that of the store so that the difference in diameter of the strip on leaving the store and entering the helix is accommodated. The guide shoes deliver the strip to guide rollers rotating with the guide shoes by which the strip is guided in a spiral to non-rotating helix-forming shoes from which the coils of the helix are delivered in an axial direction.
