Abstract
Un método perfeccionado de formar un muelle de expansión, que comprende proporcionar una tira metálica alargada con una parte de base y una pluralidad de pies que se extienden desde dicha parte de base, enrollar dicha tira en un mandril de diámetro menor que el diámetro del muelle en uso, con la base de dicha tira junto a dicho mandril y los pies de la misma extendiéndose radialmente hacia fuera desde ella, y mecanizar dicho resorte mientras se encuentra en dicho mandril, para darle un diámetro exterior uniforme
