Description

Verfahren zum fortlaufenden Herstellen von Seitennahtbeuteln mit Bodenfalte In dem Patent 1033 021 ist -ein Verfahren zum fortlaufenden Herstellen von Seitennahtbeuteln mit Bodenfalte beschrieben, bei welchem man eine doppelt liegende, an den Rändern mit nach innen geschlagenen Längsfalten versehene Folienbahn aus schweißbarem Kunststoff in bestimmten Abständen quer zur Folienbahn verschweißt und mittels der Länge nach durch diese Schweißnähte gehender Schnitte und eines in Transportrichtung der Folienbahn gehenden Mittelschnittes durchtrennt. Das Verfahren ist dadurch gekennzeichnet, daß man einen nahtlosen Seitenfaltenschlauch aus Polyäthylen in der angegebenen Weise quer verschweißt und quer und längs durchtrennt.Method for the continuous production of side-seam bags with a bottom gusset Patent 1033 021 describes a method for the continuous production of side-seam bags with a bottom gusset, in which a double-lying film web made of weldable plastic with inwardly folded longitudinal gussets at the edges is transversely arranged at certain intervals welded to form the film web and severed by means of cuts going lengthwise through these weld seams and a central cut going in the transport direction of the film web. The method is characterized in that a seamless gusseted tube made of polyethylene is welded transversely in the specified manner and severed transversely and longitudinally.

Gemäß der Erfindung kann man auch in der Weise verfahren, daß das Querverschweißen unter Anwendung des Trennschweißens ausgeführt wird.According to the invention you can also proceed in such a way that the Cross welding is carried out using cut welding.

An Hand des folgenden Beispiels und durch Bezugnahme auf die Abbildung, ine#velcher in vereinfachter Weise in einer Draufsicht dargestellt ist, wie die Beutel nach der Erfindung hergestellt werden, wird das Verfahren weiter erläutert. Von einer Rolle R läuft ein mit Seitenfalten 2 von je 3 cm Tiefe versehener, flach liegender Schlauch 1 von 30 cm Breitebei eingeschlagenen Seitenfalten 2 gemessen - aus Polyäthylen ab. Der Schlauch wird in Abständen von 16 cm durch Legen von Trennschweißnähten 3 quer durchgetrennt und gleichzeitig damit den Trennungskanten entlang durchgehend verschweißt. Dadurch werden 16 cm lange, beiderseits zugeschweißte Abschnitte 4 von dem Seitenfaltenschlauch abgetrennt. Die Schlauchabschnitte 4 werden dann quer zu den Trennschweißnähten 3 durch Schnitte 5 in der Mitte durchgetrennt, wodurch aus jedem Abschnitt 4 zwei Beutel 6 von 16 cm Breite und 15 cm Höhe entstehen. Das Trennschweißverfahren ist an sich bekannt. Gegenstand der vorliegenden Erfindung ist die Anwendung des Trennschweißens nur insoweit, als sie in Verbindung mit dem durch das Hauptpatent 1033 021 geschützten Verfahren erfolgt.The method is further explained with the aid of the following example and by referring to the figure, in which a top view of how the bags according to the invention are produced in a simplified manner. From a roll R a flat tube 1 with gussets 2 each 3 cm deep and 30 cm wide, measured with folded gussets 2 - made of polyethylene, runs off. The hose is cut transversely at intervals of 16 cm by laying separating welds 3 and at the same time it is continuously welded along the separating edges. As a result, 16 cm long sections 4 welded shut on both sides are separated from the side-gusseted tube. The tube sections 4 are then severed transversely to the separating weld seams 3 by cuts 5 in the middle, as a result of which two bags 6 16 cm wide and 15 cm high are created from each section 4. The separation welding process is known per se. The subject of the present invention is the use of cut-off welding only insofar as it is carried out in connection with the process protected by the main patent 1033 021.
