发明名称 Anti-skiving device for photographic film
摘要 An anti-skiving device used for beveling an edge of photographic film so that when the film is processed the emulsion or anti-halation backing on the base of the photographic film will not flake or skive. The device eliminates flaked or skived material from the edge of the film from being processed on the film itself, which heretofore caused an unsightly appearance on the processed film.
