Une partie d'angle de virage de la liaison oscillante d'inversion (40) est articulée et un axe d'articulation est horizontal et perpendiculaire à une direction de mouvement de la base de perforateur (21). Une traverse de la liaison oscillante d'inversion (40) est une extrémité d'entraînement et l'extrémité d'entraînement est raccordée au mécanisme de liaison oscillante de came. Un bras vertical de la liaison oscillante d'inversion (40) est une extrémité entraînée et l'extrémité entraînée correspond à une surface d'extrémité de frappe d'une seconde aiguille de pré-perforation d'une tige de cisaillement. Une riveteuse à contact électrique composite triple comprenant l'inverseur comprend un curseur principal (26), un dispositif d'admission de fil, un moule de cisaillement à fil, une base de moule, un dispositif de came permettant de commander des parties concernées de la machine afin de travailler en coordination et un inverseur. Dans le procédé de débogage de la riveteuse, les modules séparés s'adaptent à l'installation de moules présentant différentes précisions. Dans le procédé de production, des sections transversales de matériaux de fil sont combinées de sorte qu'une surface lisse soit disposée face à une surface rugueuse et qu'une surface rugueuse soit disposée face à une surface lisse, ce qui permet de développer la surface de contact, d'accroître la résistance de soudage et la performance de conduction et d'améliorer la qualité des produits de type rivet.
