Title (EN) LASER-CLEANABLE WINDING CORES AND CLEANING METHOD THEREFOR
(FR) CYLINDRES D'ENROULAGE NETTOYABLES PAR LASER, ET PROCEDE DE NETTOYAGE POUR CES CYLINDRES
Abstract:
(EN) A winding core (10) has an outer surface that is reflective for reflecting a laser beam used for cutting through residual material wound about the core so that the core can be reused for winding new material. A cleaning method entails using a laser beam (44) to cut through residual material (m) wound about a core, and reflecting the laser beam from a reflective outer surface of the core so as to prevent damage to the core.
(FR) L'invention concerne un cylindre (10) d'enroulage comprenant une surface externe réfléchissante qui permet de réfléchir un faisceau laser utilisé pour sectionner le matériau résiduel enroulé autour du cylindre, afin de permettre la réutilisation de ce dernier pour l'enroulage de matériau neuf. L'invention se rapporte en outre à un procédé de nettoyage consistant à sectionner le matériau résiduel (m) enroulé autour du cylindre à l'aide d'un faisceau (44) laser, et à provoquer la réflexion du faisceau laser sur la surface externe réfléchissante du cylindre afin qu'il n'endommage pas le cylindre.
