In the present invention, in the intermittent motion-part of the bag machine, the zipper is cut apart at the location that is to be the edge of the bag, the ends formed by the cutter moved laterally relative to each other exposing the ends and the slide (11) is inserted over one of the exposed ends.</p> |
