In an apparatus for making a wire helix by winding a wire about a mandrel by means of a rotating wire guide which withdraws wire from a storage reel, the mandrel is rotatably supported in the wire guide and has such a moment of inertia with respect to its axis of rotation that any torque transmitted by the rotating wire guide to the mandrel is insufficient to cause a revolving displacement of the latter.
