Abstract

L'invention concerne un procédé pour fixer métallurgiquement à demeure une bande (9) en aluminium à une bande (8) en cuivre, selon lequel les deux bandes (8, 9) mues parallèlement entre elles dans leur direction longitudinale sont amenées sur leurs surfaces destinées à un contact mutuel dans un dispositif de nettoyage (3) sous gaz protecteur continuellement libéré d'oxydes et ensuite vers un dispositif de compression (4) dans lequel elles sont pressées avec leurs surfaces nettoyées l'une contre l'autre et reliées l'une à l'autre en une bande d'un seul tenant (11). Les deux bandes (8, 9) sont guidées sans interruption sous gaz protecteur jusque dans le dispositif de compression (4), raison pour laquelle le dispositif de nettoyage (3) et le dispositif de compression (4) sont regroupés en une unité pourvue d'un boîtier (7) entourant une chambre continue. Les deux bandes (8, 9) ou encore la bande d'un seul tenant (11) sont tirées à travers le dispositif de nettoyage (3) et le dispositif de compression (4) au moyen d'un appareil de traction (5) disposé derrière le dispositif de compression (4).
