Abstract

Ein Verfahren dient zur Herstellung von Stapeln aus Beuteln aus thermoplastischem Kunststoff, die von einer schlauchförmigen oder halbschlauchförmigen Folienbahn oder einer Folienbahn mit auf das mittlere Bahnteil umgeschlagenen Seitenteilen durch Querschweißtrennähte und/oder Schweißnähte und Trennschnitte abgeschweißt und/oder abgetrennt und gestapelt werden. An die noch in der Bahn zusammenhängenden, die späteren Beutel bildenden Bahnabschnitte werden lappenartige Folienabschnitte begrenzende Abreißperforationslinien angebracht, die mit Stapellöcheren versehen und/oder in den Stapeln miteinander verblockt werden. Damit einerseits während der Herstellung die Ausgangsbahn durch Abreißperforationslinien nicht in einer Weise geschwächt wird, daß durch das Herstellungsverfahren bedingte Zugspannungen in der Bahn nicht mehr sicher übertragen werden können, und andererseits eine Ausbildung der Steglängen der Abreißperforationslinien gestattet wird, die einen zerstörungs­ freien Abriß der Beutel von den späteren Beutelstapeln ermöglicht, werden die Abreißperforationslinien (5) mit unterschiedlich langen Stegen (9) gestanzt, wobei die Steglängen dem Kraftverlauf beim Abreißen der Beutel entlang der Abreiß­ perforationslinie (5) in der Weise angepaßt sind, daß ein Abriß entlang der Abreißperforationslinie (5) gewährleistet ist (einzige Figur). One method is used to make stacks from bags thermoplastic made by a tubular or semi-tubular film web or a film web with on the middle part of the web Cross weld seams and / or weld seams and separating cuts welded and / or separated and stacked. To the still connected in the web, the later bags forming web sections are tab-like film sections limiting tear perforation lines attached with Provide stack holes and / or in the stack with each other be blocked. So that on the one hand during production Exit path through tear perforation lines not in any way is weakened that due to the manufacturing process Train tension can no longer be transmitted safely can, and on the other hand training the web lengths of the Tear-off perforation lines are allowed, which are destructive free tear-off of the bags from the later stack of bags allows the tear-off perforation lines (5) with different lengths of webs (9) punched, the web lengths the course of force when the bags are torn off along the tear     perforation line (5) are adapted in such a way that a demolition along the tear-off perforation line (5) is guaranteed (only figure).
