PROBLEM TO BE SOLVED: To improve an apparatus for correcting the printing pitch of a plastic film so as not to require selection and adjustment to reduce a printing pitch correcting cost. SOLUTION: Plastic films 1H and 1L are fed longitudinally and discontinuous break forming mechanisms 13H and 13L are provided to plastic film feed routes to form discontinuous breaks to the plastic films. Tension applying mechanisms 18H and 18L are provided to the plastic film feed routes to apply longitudinal tension to the plastic films and, when the longitudinal tension is applied to the plastic films, the plastic films are stretched by the lateral discontinuous breaks to correct the printing pitch of the plastic films.
