Abstract

L'invention concerne un procédé et un dispositif (12) destiné à la manutention de matière (26) en feuille et/ou plate enroulée sur des rouleaux (14, 15) et servant de matière d'emballage de marchandises de détail, de conteneurs ou de combinaisons d'articles similaires. Pour continuer à faire fonctionner le processus d'emballage, un rouleau (15) au moins partiellement déroulé et/ou épuisé (15) est retiré d'au moins une position de montage (EB1 ; EB2) d'une machine d'emballage (10) et remplacé par un nouveau rouleau (14) contenant un matériau (26) en feuille et/ou plat de sorte que, après la positionnement d'un nouveau rouleau (14), la couche extérieure (36) de celui-ci est reliée, notamment soudée ou collée à une partie d'une bande de matière guidée dans la chaîne d'emballage (26) au voisinage ou au niveau de son extrémité libre (50) pour former une bande de matière continue (26). La bande de matière (26) retirée du nouveau rouleau (14) est détectée au moyen d'un dispositif de manipulation et/ou de préhension commandable (52) et est déplacée en direction de la bande de matière déjà introduite dans la chaîne d'emballage (26) et/ou d'un dispositif de fixation et/ou de soudage (32).
