ABSTRACT:
In a continuous bag-making process, the film and zipper track moves intermittently through a bag machine in a continuous stream, so there is no end to the zipper track on which the slider can be inserted. 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 slider is inserted over one of the exposed ends.
