Perforator apparatus and perforating method for photo film, and photo film working/securing apparatus and method |
摘要 |
A perforator apparatus for continuous photo film includes a perforator unit having a punch and a die. The perforator unit is disposed between first and second suction chambers. The photo film is extended past each of the suction chambers. A blower applies suction of air through the suction chambers, to apply tension to the photo film through the perforator unit. The perforator unit is disposed between a feed roller and a sprocket roller, which convey intermittently the photo film by a punching length. A first pass roller continuously conveys the photo film into the first suction chamber. A first loop of the photo film in the first suction chamber is maintained with a length substantially of an arc of a semi-circle defined between the first pass roller and the feed roller. A second pass roller continuously conveys the photo film from the second suction chamber. A second loop of the photo film in the second suction chamber is maintained with a length substantially of an arc of a semi-circle defined between the second pass roller and the sprocket roller. The perforator unit forms a train of perforations in the photo film along each of its two edges when the photo film is stopped.
