Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Beuteln mit Zugbändern aus thermoplastischer Kunststoffolie, die in Saumumschläge entlang der Folienränder eingelegt werden, wobei die Saumumschläge angeschweißt werden und die Beutel durch Querschweißen der Seitennähte abgeteilt werden, bei dem doppellagige Zugbänder durch Falten und Auftrennen eines Folienbandes verwendet werden und Zugrifflöcher und Entlüftungsöffnungen in die flachgelegte noch nicht zu Saumumschlägen gefaltete Folienbahn gestanzt werden. The invention relates to a method and an apparatus for Manufacture of bags with drawstrings made of thermoplastic Plastic film wrapped around the edges of the film be inserted, the hem envelopes being welded on and divided the bags by cross welding the side seams be, in the double-layered drawstrings by folding and Cutting a film tape can be used and Access holes and vents in the flat lay yet foil sheet not folded into hem envelopes are punched.
