Abstract
The semi-continuous manufacturing of wave-guides of great length formed by an insulated wire wound in a helicoidal way with its turns contacting one another, involves forming a first length of the guide on a cylindrical mandrel with the mandrel and the length being pushed longitudinally over a distance virtually equal to the length of the latter, the length is stopped in this position, and the mandrel is brought back to its original position to enable a new length of guide to be formed on it, and so on.
