Abstract

The method involves forming the sheet (1) into a tube around a filling pipe (2), welding the edges to form a longitudinal seam (4) and forming corner welds and cross-welds. The novelty is that one of the corner welds forms part of the longitudinal seam.

Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the Preamble of claim 1.

Aus der EP 0 627 355 sind ein Verfahren und eine Vorrichtung zur Herstellung von Schlauchbeuteln nach dem Oberbegriff des Patentanspruchs 1 bekannt. Die Längssiegelnaht dieser Schlauchbeutel ist als Umle­ genaht ausgebildet und im Bereich einer Seitenwand angeordnet. Diese regelmäßig als Werbefläche dienende Seitenwand wird also durch die Umlegenaht unterbrochen.EP 0 627 355 describes a method and a method Device for the production of tubular bags according to the preamble of claim 1 known. The The longitudinal sealed seam of this tubular bag is as umle sewn and in the area of a side wall arranged. These regularly as advertising space serving side wall is thus through the fold seam interrupted.

Aus der WO 00/37245 ist gleichfalls eine Vorrichtung zum Herstellen von Schlauchbeutelpackungen nach dem Oberbegriff des Patentanspruchs 1 bekannt. Deren Längsnaht ist ebenfalls in einer Seitenwand angeordnet.A device is also from WO 00/37245 for the manufacture of tubular bag packs after The preamble of claim 1 is known. their Longitudinal seam is also in a side wall arranged.

Der Erfindung liegt als Aufgabe zugrunde, standfähige Schlauchbeutel ohne sichtbare Längssiegelnaht zu schaffen. Diese Aufgabe wird nach dem kennzeichnenden Teil des Patentanspruchs 1 gelöst.The invention has for its object Sturdy tubular bags with no visible To create longitudinal seal seam. This task is after the characterizing part of claim 1 solved.

Die Ausgestaltung der Längssiegelnaht zugleich als Ecknaht gestattet eine ununterbrochene Gestaltung der Seitenwände des Schlauchbeutels als Werbefläche. Etwaige Ungenauigkeiten bei der Führung der beiden Folienränder wirken sich optisch nicht aus. Die möglichen Motive auf den beiden an die Längssiegelnaht anschließenden Seitenflächen schließen nicht unmittelbar aneinander an. The design of the longitudinal seal seam also as Corner seam allows uninterrupted design the side walls of the tubular bag as advertising space. Any inaccuracies in the management of the two Foil edges have no visual impact. The possible motifs on the two to the Longitudinal seal seam adjoining side surfaces do not directly connect to each other.  

Die Erfindung wird nachstehend anhand der Figur an einem Ausführungsbeipiel erläutert.The invention is described below with reference to the figure an exemplary embodiment explained.

Die Figur zeigt schematisch den Aufbau zur kontinuierlichen Durchführung des Verfahrens. Zunächst wird die ebene Folienbahn 1 in bekannter Weise durch eine Formschulter um ein rechteckiges Füllrohr 2 zu einem Schlauch geformt. Die an einer Ecke des Füllrohrs 2 angeordnete Siegeleinrichtung 3 siegelt die Längssiegelnaht 4 als Umlegenaht. Die Längssiegelnaht 4 bleibt der Ecke des Füllrohrs 2 im weiteren Verlauf zugeordnet. Dann werden in bekannter Weise mit Formteilen 5 die drei anderen Ecknähte geformt und mit nachgeordneten Siegeleinrichtungen 6 gesiegelt. Dabei wird die Längssiegelnaht 4 nachgesiegelt. Schließlich wird ein überstehender Teil der Längssiegelnaht 4 durch Schneiden mit einer bekannten Schneidvorrichtung 7 entfernt. Nach dem Schneiden weisen alle vier Ecknähte die gleiche Breite auf. Die Längssiegelnaht 4 ist von den anderen drei Ecknähten optisch nicht unterscheidbar. The figure shows schematically the structure for the continuous implementation of the method. First, the flat film web 1 is formed in a known manner by a shape shoulder around a rectangular filling tube 2 to form a tube. Which is arranged at a corner of the filling tube 2 sealing device 3 seals the longitudinal sealing seam 4 as Umlegenaht. The longitudinal sealing seam 4 remains assigned to the corner of the filling tube 2 in the further course. Then the three other corner seams are formed in a known manner with molded parts 5 and sealed with downstream sealing devices 6 . The longitudinal sealing seam 4 is resealed. Finally, a protruding part of the longitudinal sealing seam 4 is removed by cutting with a known cutting device 7 . After cutting, all four corner seams have the same width. The longitudinal seal seam 4 is optically indistinguishable from the other three corner seams.
