Abstract

Procédé pour fabriquer des éléments filiformes de longueur finie à partir de fil métallique. Selon l'invention, on fait défiler le fil dans un milieu dont la température est inférieure à la température de solidification du métal ou de l'alliage formant le fil et on sectionne le fil à l'état liquide.
