In order to accelerate the processing speed of a form-fill-seal packaging machine by continuously running a strip-like film even if using a printing device of an intermittent printing type the structure and control of which are comparatively facilitated. Arm members (35) pivoting around support axes (36) are provided on a feed path of a strip-like film (F). Rollers (37,38) guiding the film (F) are provided at front and rear end portions of the arm members (35) whereby portions of the film (F) meander. A stopper member (32) stopping the running of the film (F) is arranged between accumulating portions (A,B). Printing is carried out on the film (F) by a printer (28) of an intermittent printing type in a period of time during which a portion of the film (F) is stopped by the stopper member (32) and the continuous running of the film (F) is not hampered during this stoppage period since a portion of the film (F) is accumulated at the accumulating portion (A) on the downstream side. <IMAGE> |
