Abstract

PURPOSE:To remove static electricity generated in a laminating film at a time of peeling by arranging a static eliminating needle abutting on the laminating film in the vicinity of the downstream side in the peeling part of a laminating film roll. CONSTITUTION:A laminating film 6b is peeled from the peeling part 5c of a laminating roll 5b and led to the upper part of a laminating film roll unit X. A static eliminating needle 40 is held by a holding member 39 made of a plate spring and arranged in the vicinity of the downstream side in the peeling part 5c in which the laminating film 6b is peeled. The free end of the static eliminating needle 40 abuts on the surface of the laminating film 6b just after peeling to remove static electricity generated in a time for peeling. Further the static eliminating needle 40 is constituted so that it always abuts and follows on the rear of the laminating roll 5b by elastic force of the holding member 39 even when the position of the laminating film 6b is changed by the residual amount of the film. Accordingly static electricity is always removed from the peeled laminating film 6b by the static eliminating needle 40.
