Abstract

L'invention concerne un procédé et un dispositif d'acheminement, de fourniture, de manipulation et/ou d'échange de rouleaux (12, 20) comportant un matériau plat et/ou un matériau sous forme de film, enroulé sur ces derniers, servant de matériau d'emballage (22) pour l'emballage de charges isolées, fûts ou ensembles d'articles similaires. Dans ce dispositif et selon ce procédé, des rouleaux (20) au moins pratiquement entièrement dévidés et/ou épuisés sont prélevés à partir d'au moins une position de montage (EB1, EB2) d'une machine d'emballage (14) puis un nouveau rouleau (12) comportant un matériau plat et/ou sous forme de film est introduit respectivement dans la position de montage (EB1, EB2) respective. De nouveaux rouleaux (12) de la machine d'emballage (14) sont fournis selon un acheminement défini et sont introduits dans la position de manipulation (EB1, EB2) respective, après le prélèvement au préalable d'un rouleau (20) consommé. Ladite au moins une position de montage (EB1, EB2) de la machine d'emballage (14) est définie par au moins un mandrin de réception (70) rotatif servant à recevoir et à maintenir, de manière rotative, les rouleaux (12) à dérouler dans la machine d'emballage (14), comportant le matériau plat et/ou sous forme de film. Ledit au moins un mandrin de réception (70) est déplacé dans son sens axial lors du prélèvement d'un rouleau (20) au moins approximativement entièrement dévidé et/ou consommé et/ou lors de l'insertion d'un nouveau rouleau (12).
