The present invention relates to a film slitting roll and, more specifically, to a direct laser cutting on a roller to prevent the flapping of the moving film. The roller comprises an airlock shaft, and the slitting roll is prepared based on the size of the film on the airlock shaft. The slitting roll is fixed or released by the airlock shaft without a specific fixing unit, and is prevented from flapping since the film is directly cut from the slitting roll. |
