Abstract

La présente invention concerne un procédé de commande d'un processus de rouleau à rouleau. Selon un mode de réalisation de la présente invention, le procédé commande un processus de rouleau à rouleau d'un appareil à procédé de rouleau à rouleau comprenant une unité de traitement de film servant au traitement d'un film et une unité de transport de film servant à délivrer le film à l'unité de traitement de film et à récupérer le film de celle-ci. Le procédé selon l'invention comprend les étapes suivantes : suspension du transport du film se trouvant dans l'unité de traitement de film ; calcul d'une valeur d'erreur de registre pour le film à partir d'au moins un premier repère d'alignement disposé sur le film se trouvant dans l'unité de traitement de film ; alignement de l'unité de traitement de film au moyen de la valeur d'erreur de registre et d'au moins un deuxième repère d'alignement disposé sur l'unité de traitement de film ; transport du film se trouvant dans l'unité de traitement de film ; et traitement du film transporté depuis l'unité de traitement de film.
