Abstract:
1. An apparatus for inspecting continuous film laminate including an optically functional continuous film having a releasable film adhered to one of the opposite sides thereof, or including an optically functional continuous film having a releasable film adhered to one of the opposite sides thereof and a protective film adhered to the other side thereof, for a presence of any defect in said optically functional continuous film, and making the film laminate usable in a laminating apparatus for laminating the optically functional continuous film to a product panel, the apparatus comprising: a delivering device for unwinding the continuous film laminate from a roll and delivering the laminate toward an inspection station; a releasing device for releasing the releasable film from the film laminate before the film laminate reaches the inspection station; an inspection device in the inspection station for inspecting the optically functional continuous film from which the releasable film is released for the presence of any defect; a control device for calculating a coordinate position of a defect if such defect has been detected; and a releasable film laminating device for unwinding a releasable film from a roll and laminating the unwound releasable film to said one side of the optically functional continuous film after the inspection has been completed.
