Abstract (en)
The method involves forming a packaging bag in a movement film and welding opening and closing sections on the film, where the sections comprise a set of actuating cursors (4). A cut-out is made in the sections, where the cut-out has a length that is greater than the width of each cursor. One of the cursors is ejected from the sections by the cut-out, when the cursors are not found on the sections. A cut-out of the sections is performed regularly along the sections, where each cut-out is separated from the other cut-outs by a distance that is multiple of a step (6) of the bag.
