Description

Die Erfindung betrifft eine gelegeverstärkte Folienbahn nach dem Oberbegriff des Patentanspruchs.
Bei einer aus der US-PS 37 91 911 bekannten gelegeverstärkten Folienbahn dieser Art fassen die Folien das von diesen abge­ deckte Gelege beidseits bis über die Umkehrpunkte der Bändchen hinaus vollständig zwischen sich ein. Wird aus einer derartigen aus einem beidseits mit Folien kachierten Gelege bestehenden Folienbahn eine durch eine Längsschweißnaht geschlossene Schlauchbahn hergestellt, von der anschließend Säcke abge­ schweißt oder Abschnitte zur Herstellung von Säcken abgetrennt werden, ist die Ausbildung einer ausreichend festen Schweißnaht wegen der vielen Lagen, die im Schweißnahtbereich miteinander zu verbinden sind, fertigungstechnisch schwierig.
Aufgabe der Erfindung ist es daher, die gelegeverstärkte Folien­ bahn nach dem Oberbegriff des Patentanspruchs 1 so zu gestalten, daß sie sich mit einer sicheren und festen Längs­ schweißnaht zu einem Schlauch verbinden läßt.
Erfindungsgemäß wird diese Aufgabe bei einer gelegeverstärkten Folienbahn der gattungsgemäßen Art durch die kennzeichnenden Merkmale des Patentanspruchs gelöst.
Beim Bilden der Schweißnaht sind wegen des erfindungsgemäßen Versatzes der Bahnen und des Geleges nur weniger Lagen miteinander zu verschweißen, so daß eine sicherere und feste Längsschweißnaht erzielt werden kann. Nach dem Bilden der Längs­ schweißnaht ist das Kunststoffbändchengelege sowohl auf der Sack­ außenseite als auch im Sackinnern durch Folien abgedeckt, so daß es weder mit in den späteren Säcken verpackten Gegenständen noch mit äußeren Hindernissen verhaken kann.
Aus der CH-PS 6 15 638 ist eine gewebeverstärkte Papierbahn für die Sackherstellung bekannt, bei der die Gewebebahn an den Längs­ kanten versetzt zur Papierbahn angeordnet ist. Diese Veröffent­ lichung betrifft jedoch ausschließlich die Verklebung von Papier­ säcken mit einer Papierlage, so daß wir keine Hinweise in Bezug auf die spezielle Problematik bei der Herstellung von festen Schweißnähten bei mehrlagigen Kunststoffsäcken entnommen werden können. Auch läßt sich dieser Veröffentlichung keine Anregung dafür entnehmen, daß das nichtgewebte Gelege beim Schweißvorgang in vorteilhafter Weise im Randbereich noch zusätzlich fixiert wird.
Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt
Fig. 1 eine gelegeverstärkte Folienbahn in Draufsicht mit versetzt zueinander angeordneten Deckfolien und
Fig. 2 einen aus der in Fig. 1 dargestellten Folienbahn gebildeten Folienschlauch im Querschnitt.
Bei der in Fig. 1 dargestellten Folienbahn 8 ist das Bändchen­ gelege 9 breiter als die Folienbahn 8 selbst, so daß die Umkehr­ punkte 10 einer Seite des Geleges 9 über den Rand 11 der Folien­ bahn 8 vorstehen. Auf das Gelege 9 ist eine zweite Folienbahn 12 aufgelegt, die gegenüber der Folienbahn 8 so weit seitlich versetzt ist, daß die überstehenden Teile des Bändchengeleges 9 von oben abgedeckt werden. Bildet man nun aus einer derart ver­ stärkten Folienbahn den aus Fig. 2 ersichtlichen Schlauch, ist das Gelege sowohl innen als auch außen von einer Folienbahn abgedeckt. Die Folien 8 bzw. 12 werden bei der Schlauchbildung im Überlappungsbereich direkt mit sich selbst verschweißt, so daß sie das Gelege 9 zwischen sich einschließen. Die Schweiß­ hitze braucht also für die Nähte 13 nicht so hoch zu sein, wie sie sein müßte, wenn die Schweißnähte durch alle einander überlappenden Lagen hindurch ausgeführt werden müßten. Natürlich ist es auch möglich, statt der Schweißnähte 13 die Längsnähte durch Einlegen eines extrudierten Hot-Melt-Streifens o.dgl. zu bilden.

Claims (1)

  1. Gelegeverstärkte Folienbahn, bestehend aus einem beidseitig mit Folien abgedeckten Gelege, insbesondere zur Herstellung von Säcken, bei der das Gelege aus sich kreuzenden, zick-zack-förmig über die Breite des Geleges verlaufenden Bändchen mit seitlichen Umkehrpunkten besteht, dadurch gekennzeichnet, daß die beiden Folienbahnen (8, 12) in Querrichtung gegeneinander versetzt liegen, so daß dadurch in Längsrichtung die Rand­ streifen des Bändchengeleges (9) einschließlich der Umkehrpunkte (10) der Bändchen jeweils nur einseitig von einer Folienbahn (8, 12) abgedeckt sind.
