Abstract
(EN)
A winding core 1 for an optical film has a core member 2 and a dummy film 31 wound around the core member 2. The dummy film 31 has an end 31a to which an optical film can be connected. By connecting an optical film to the dummy film 31 of the winding core, the optical film can be joined to another optical film without wasting the optical films.
(FR)
Un noyau d'enroulement 1 pour un film optique comporte un élément de noyau 2 et un film factice 31 enroulé autour de l'élément de noyau 2. Le film factice 31 a une extrémité sur laquelle un film optique peut être connecté. En connectant un film optique au film factice 31 du noyau d'enroulement, le film optique peut être joint à un autre film optique sans gaspiller les films optiques.
(JA)
光学フィルム用巻き芯1は、芯部材2と、前記芯部材2に巻き付けられたダミーフィルム31であって、光学フィルムが連結され得る先端部31aを有するダミーフィルム31と、を有する。前記巻き芯のダミーフィルム31に光学フィルムを連結することにより、光学フィルムを無駄にすることなく、前記光学フィルムともう1つの光学フィルムを接合できる。
