Abstract

L'invention concerne un procédé et un dispositif pour stratifier des bandes de feuilles. De préférence, on stratifie une feuille de cuivre (1) sur une feuille en plastique (2) présentant une structure conductrice. Pendant la stratification des bandes, avant leur solidarisation, les bandes de feuilles sont soumises à un contrôle visuel, et les écarts de tolérances concernant l'alignement mutuel des bandes de feuilles sont corrigés par traction ou poussée. Selon l'invention, le mouvement des bandes de feuilles les unes par rapport aux autres lors de l'alignement est facilité par des interruptions non continues (4) dans au moins une des bandes de feuilles ou par séparation d'une bande de feuille.
