Abstract

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von mehrwandigen, vorzugsweise doppelwandigen Kunststoffbeuteln, insbesondere Zugbandbeuteln, aus thermoplastischen Kunststoffolienbahnen (4,6), die zum Zwecke einer einfachen Handhabung bei vergleichsweise hohen Produktionsgeschwindigkeiten zunächst im Vergleich zu einer einlagigen Bahnbreite jeweils von einer Abwickelrolle (3,5) doppellagig, mit im wesentlichen halber Bahnbreite abgewickelt und danach einlagig zu voller Bahnbreite aufgefaltet werden, worauf die flachgelegten Folienbahnen nach Art eines U umgefaltet und aus diesen schließlich in an sich bekannter Weise in einem Beutelherstellautomaten die Kunststoffbeutel bzw. Zugbandbeutel hergestellt werden.

Figure 00000001
The invention relates to a method for producing multi-walled, preferably double-walled plastic bags, in particular drawstring bags, from thermoplastic plastic webs (4, 6) which, for the purpose of simple handling at comparatively high production speeds, first of all in comparison to a single-layer web width from an unwinding roll ( 3.5) double-ply, unwound with essentially half the width of the web and then unfolded to the full web width in one layer, whereupon the flat foil webs are folded over in the manner of a U and the plastic bags or drawstring bags are finally produced therefrom in a manner known per se in a bag-making machine.
