摘要:
A perforator apparatus for continuous photo film (10) includes a perforator unit (68) having a punch (66) and a die (67). The perforator unit is disposed between first and second suction chambers (82, 83). The photo film is extended past each of the suction chambers. A blower (93, 100, 101) applies suction of air through the suction chambers, to apply tension (TA, TB) to the photo film through the perforator unit. The perforator unit is disposed between a feed roller (84) and a sprocket roller (85), which convey intermittently the photo film by a punching length. A first pass roller (86) continuously conveys the photo film into the first suction chamber (82). A second pass roller (87) continuously conveys the photo film from the second suction chamber (83). A first loop (RA) and second loop (RB) of the photo film in the first and second suction chamber respectively are maintained with a length substantially of an arc of a semi-circle defined between the first pass roller and the feed roller and the second pass roller and the sprocket roller respectively. The perforator unit forms a train of perforations in the photo film along at least one of its edges when the photo film is stopped. Further a photo film working/securing apparatus is disclosed by which a photo film strip (23) of predetermined length is cut from continuous photo film (10) and a combination of said photo film strip (23) and a spool (25) is produced with said photo film strip (23) secured to said spool (25).
