Description

Verfahren zum fortlaufenden Herstellen von Seitennahtbeuteln mit Bodenfalte In dem Hauptpatent 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.Process for the continuous production of side-seam bags with a bottom gusset In the main patent is a method for continuously manufacturing side seam bags described with a bottom fold, with a double lying on the edges with inwardly folded longitudinal folds made of weldable plastic welded transversely to the film web at certain intervals and along the length cuts going through these weld seams and one in the transport direction of the film web going central cut. The procedure is characterized by that you can use a seamless gusseted tube made of polyethylene in the specified Way welded crosswise and cut crossways and lengthways.

Gemäß der Erfindung kann man auch in der Weise verfahren, daß bei dem nahtlosen Seitenfaltenschlauch aus Polyäthylen erst der Länge nach ein Schnitt angebracht und danach durch Legen von Trennschweißnähten die Ouerverschweißung gleichzeitig mit der Querdurchtrennung ausgeführt wird.According to the invention one can also proceed in such a way that at the seamless gusseted tube made of polyethylene is only cut lengthways attached and then the over-welding at the same time by laying separating welds is carried out with the transverse severing.

Es ist an sich bekannt, bei der Herstellung von Beuteln eine ihrer Länge nach gefaltete Folienbahn mit Querschweißungen zu versehen, danach einen Längsschnitt in der Bahnmitte anzubringen und dann erst von den beiden Bahnhälften die Beutel durch quergehende Schnitte abzutrennen. Doch hat man in dieser Weise noch nicht Beutel mit Bodenfalte hergestellt. Auch erfolgt bei dem Verfahren nach der Erfindung das Längszerteilen der Seitenfaltenschlauchbahn schon, bevor sie quer verschweißt wird. Es ist an sich ferner bekannt, bei der Herstellung von Beuteln aus Polyäthylenfolien das sogenannte Trennschweißen anzuwenden. Doch konnte man nicht voraussehen, daß die Anwendung des Trennschweißens in Verbindung mit der Maßnahme, vorher den Längsschnitt bei dem Seitenfaltenschlauch anzubringen, die Arbeitsweise ist, mit der man beim Herstellen von Seitennahtbeuteln mit Bodenfalte aus einem Polyäthylenseitenfaltenschlauch am leichtesten mit den Schwierigkeiten fertig wird, welche beim Transport des Schlauches durch die Beutelmaschine wegen seiner Weichheit auftreten.It is known per se to use one of theirs in the manufacture of bags To provide lengthwise folded film web with cross welds, then a longitudinal cut to be attached in the middle of the web and only then the bags from the two web halves to be separated by transverse cuts. But one has not yet done so in this way Bag made with bottom gusset. Also takes place in the method according to the invention the lengthways splitting of the side-gusseted tubular web before it is welded transversely will. It is also known per se in the manufacture of bags from polyethylene films to use the so-called cut-off welding. But one could not foresee that the use of cut-off welding in connection with the measure, previously the longitudinal cut to be attached to the gusseted tube, the way of working is the same as that used for the Manufacture of side-seam bags with a bottom gusset from a polyethylene tube with side gussets easiest to cope with the difficulties encountered in transporting the hose occur through the bag machine because of its softness.

Nach dem beanspruchten Verfahren erhält man Polyäthylen-Seitennahtbeutel mit einer Bodenfalte auf einfachere Weise und mit größerer Maßgenauigkeit als nach den bisher bekannten Verfahren zur kontinuierlichen Herstellung von Seitennahtbeuteln mit Bodenfalte.The claimed process gives polyethylene side-seam bags with a bottom fold in a simpler way and with greater dimensional accuracy than after the previously known process for the continuous production of side seam bags with bottom fold.

Das Verfahren wird unter Bezugnahme auf die Zeichnung erläutert, in welcher in vereinfachter Weise in einer Draufsicht dargestellt ist, wie die Beutel nach der Erfindung hergestellt werden. In der Zeichnung ist 1 ein von der Rolle R ablaufender mit Seitenfalten 2 versehener flach liegender Schlauch aus Polyäthylen. Er wird kontinuierlich vorwärts bewegt und dabei mit einem Schnitt 6 versehen, durch den er der Länge nach geteilt wird. Mit senkrecht zum Längsschnitt 6 durch die geteilte Seitenfaltenschlauchbahn gelegten Schweißungen 3, die außer der Verschweißung 3 zugleich eine Trennung 4 längs durch die Schweißnaht bewirken, sogenannten Trennschweißungen, werden jeweils zwei Beutel ? von der geteilten Seitenfaltenschlauchbahn abgetrennt.The method is explained with reference to the drawing in which is shown in a simplified manner in a plan view, like the bags be produced according to the invention. In the drawing, 1 is one of the reels R draining flat hose made of polyethylene with gussets 2. It is continuously moved forward and provided with a cut 6 through which it is divided lengthways. With perpendicular to the longitudinal section 6 through the divided Side-gusseted tubular web welds 3, which apart from the weld 3 at the same time cause a separation 4 longitudinally through the weld seam, so-called separation welds, are there two bags each? separated from the split gusseted tubular web.
