Method and device for the production of film bags

摘要

The invention relates to a method and a device for producing foil bags comprising V-shaped inserted lateral folds and a reclosing mechanism with a slide in a top filling hole. The inventive method encompasses the following steps: window-shaped blanks (10) which delimit the top end of the subsequently formed lateral folds as well as slide blanks (11) are introduced into a planar sheeting. Reclosing mechanisms (6) that are composed of two superimposed and interconnected profiled strips and a slide are placed on the planar sheeting (2) perpendicular to the direction of the sheeting in such a way that the slides lie inside the slide blanks (11). The reclosing mechanisms (6) are connected to the sheeting only at the ends. The sheeting (2) is then directed through a folding station (7) in which the sheeting is folded and lateral folds are molded thereinto. The reclosing mechanisms (6) are joined to the sheeting by means of a sealing seam while the top end of the lateral folds is incorporated thereinto. The superimposed foil layers are finally joined by means of additional sealing seams so as to obtain a run (16) of bags which comprises bag-shaped sections and from which individual foil bags (17) are cut off.
