lui de la pointe finie. les déchets de fabrication ayant une valeur presque nulle; en outre les opérations de décolletage et autres dorment lieu à une dépense en main d'oeuvre importante et le tout conduit à un prix de revient très élevés 

  
L'invention a pour objet un procédé suivant lequel la pointe est obtenue de préférence par refoulage d'un petit tube
