Abstract
L'invention concerne les machines à fabriquer des ressorts. La machine est essentiellement constituée de deux sous-ensembles superposés et indépendants; le sous-ensemble supérieur destiné à la mise en place de l'entraîneur 25 de fil dans la position travail à l'aide de pinces mobiles 36; le sous-ensemble inférieur 10 destiné au formage du ressort par l'enroulement de l'épingle originale 4 à l'aide de l'entraîneur. Application à la fabrication de ressorts double-torsion.
