Abstract

L'invention concerne un procédé d'introduction d'au moins une bande de matière dans un dispositif de traitement. Selon l'invention, au moins une bobine sur laquelle la bande de matière est au moins partiellement enroulée est montée rotative autour d'un axe de rotation ; lors d'une opération de raccordement, on relie la bande de matière à au moins un élément d'introduction d'au moins un dispositif d'aide à l'introduction ; après l'opération de raccordement, on fait tourner la bobine de matière autour de l'axe de rotation à l'encontre du sens de dévidage jusqu'à ce que la tension de la bande de matière atteigne une première valeur prédéfinie ; lors d'au moins une opération d'introduction ultérieure, on déplace l'élément d'introduction le long d'au moins une trajectoire d'introduction définie par au moins un système de guidage du dispositif d'aide à l'introduction, la bande de matière tournant simultanément dans le sens de dévidage.
