Abstract

L'invention concerne un dispositif de retenue et de déroulement (10) pour un matériau plat et/ou de type feuille (14) enroulé sur des rouleaux (12). Ledit dispositif comprend un mandrin rotatif (16) monté au moins unilatéralement et destiné à recevoir en grande partie sans jeu une âme creuse ou cylindrique circulaire d'un rouleau (12) à dérouler, et un dispositif de guidage axial (22) mobile dans la direction longitudinale du mandrin (16) pour un rouleau (12) situé sur le mandrin (16) et monté rotatif sur ce dernier. Un entraînement motorisé sert à déplacer le dispositif de guidage axial parallèlement à la direction longitudinale du mandrin rotatif (16). Le dispositif (10) peut être équipé d'un dispositif de détection (36) servant à détecter la qualité d'une bobine et/ou le parallélisme des couches du matériau plat et/ou de type feuille (14) enroulé sur le rouleau (12). L'entraînement motorisé servant à déplacer le dispositif de guidage axial parallèlement à la direction longitudinale du mandrin rotatif (16) est accouplé par une technique de signalisation et/ou de régulation au dispositif de détection (36). L'invention concerne en outre un procédé de remplacement d'un rouleau (12) sur lequel est enroulé un matériau plat ou du type feuille (14) à l'intérieur d'un dispositif de retenue et de déroulement (10) de ce type.
