Description

Die Erfindung betrigt ein Verfahren zur kontinuierlichen Herstellung von Flachbeuteln aus kaschierter und mit einem Heißklebelack gestrichener Folie aus Aluminium oder anderen ähnlichett Stoffen. Zu diesem Zwecke werden von der sich von einer Rolle abwickelnden Stoffbahn bestimmte Längen abgeschnitten, und diese Längen werden dann auf einem umlaufenden Zylinder durch ein flach liegendes Falzmesser und eine flach liegende Falzzange flach liegend quer gefalzt. Bei dem weiteren Umlauf des sog. Zylinders trifft darin der auf ihm liegende quer gefa17te Beutelzuschnitt mit einem auf einem Gegenzylinder angeordneten beheizten Formsiegelmuster zusammen, durch dessen Druck- und Wärmewirkung der gefalzte Beutelzuschnitt an seinen beiden Längskailten und seiner Bodenkante verklebt bzw. versiegelt wird. Die vierte Seite des Beutels, nämlich die Füllöffnung, wird nach dem Füllen des Beutels vom 'Verbraucher verschlossen und versiegelt.The invention relates to a method of continuous manufacture of flat bags made of laminated film coated with a hot glue varnish made of aluminum or other similar materials. For this purpose are used by the cut off certain lengths from a roll unwinding fabric, and these Lengths are then measured on a rotating cylinder using a flat folding knife and a flat-lying pliers folded flat across it. In the further circulation of the so-called cylinder meets the transversely folded bag blank lying on it together with a heated shape seal pattern arranged on an opposing cylinder, due to its pressure and heat effect, the folded bag blank on both of them Längskailten and its bottom edge is glued or sealed. The fourth page of the bag, namely the filling opening, is used by the consumer after the bag has been filled locked and sealed.

Derartige Flachheutel sind sehr haltbar, äußerst wetterbeständig und nach dem Verschließen durchaus luftdicht, so daß'sie sich insbesondere zum Verpacken von licht-, luft- und feuchtigkeitseinpfindlichen Füllgütern, wi# Suppenkonserven, Limonadenpulvern. u. dgl., sehr gut eignen. Außerdem ist ihre Herstellung sehr einfach und wirtschaftlich.Such flat bags are very durable, extremely weather-resistant and after closing it is completely airtight, so that it is particularly suitable for packaging of light-, air- and moisture-sensitive filling goods, wi # canned soup, Soda powders. and the like, very well suited. They are also very easy to manufacture and economical.

Die Erfindung wird an Hand der Zeichnung näher erläutert. In dieser veranschaulichen Abb. i bis 5 das Querfalzen der Beutelzuschnitte, Abb. 6 und 7 den mit dem Falzzylinder zusammenarbeitenden Gegenzylinder, mit dem auf seiner .Mantelfläche angeordneten beheizbaren Formsiegelmuster und Abb. 8 den genannten Gegenzylinder mit dein Formsiegelmuster in perspektivischer Ansicht. Die sich von einer nicht dargestellten Rolle abwickelnde Stoffbahn, insbesondere kaschierte und auf der Innenseite mit einem Heißklebelack bestricherie Aluminiumfolie, gelangt in den lierzustellenden Beuteln entsprechend geschnittenen Längen auf den umlaufenden Zylinder i, auf deni die Beutelzuschnitte 2 durch ein von oben her einschwingendes, flach liegendes Falzmesser 3 und eine mit dem Zylinder mit umlaufende flach liegende Falzzatige 4 quer gefalzt und die beiden Beutel-2 a b (Abb. 4) bei dein weiteren Umlauf des fl äChell 2 , 2 Zylinders i und nach dem Ausschwitigen des Falzmessers 3 durch eine Anschlagführung 5 flach aufeinandergelegt werden. Bei dem weiteren Umlauf des Zylinders i trifft dann der Beutelztischnitt mit einem in der Pfeilrichtung tunlaufenden Gegenzylinder 6 zusammen, auf dessen 'Mantelfläche (las beispielsweise elektrisch beheizbare Forinsiegelmuster 7 auswechselbar befestigt ist. Dieses Siegelmuster besteht aus einer k-reisbogenförmig gewölbten, derKrümmung desGegenzyliriders6 angepaßten etwa rechteckigen Platte, die auf den beiden Längsseiten und einer Querseite ralitileiiartig durch erhabene Stege 8 begrenzt wird, die elektrisch beheizbar und auf ihrer _Mantelfläche mit irgendeiner feinen Riffelung 9 versehen sind.The invention is explained in more detail with reference to the drawing. In this Fig. 1 to 5 illustrate the cross-folding of the bag blanks, Fig. 6 and 7 the counter-cylinder working together with the folding cylinder, with the heatable seal pattern arranged on its .Mantle surface and Fig. 8 the mentioned counter-cylinder with the seal pattern in a perspective view. The fabric web unwinding from a roll (not shown), in particular laminated and coated on the inside with a hot-melt adhesive lacquer, reaches the circumferential cylinder i, on which the bag blanks 2 swing in from above and which is lying flat, in the bags that are to be provided with correspondingly cut lengths Folding knife 3 and a folding sheet 4 lying flat all round with the cylinder, folded across and the two bags 2 a b (Fig. 4) during your further rotation of the flat 2 , 2 cylinder i and after the folding knife 3 has been switched off by a stop guide 5 are laid flat on top of one another. During the further rotation of the cylinder i, the bag table cut meets a counter-cylinder 6 running in the direction of the arrow, on whose outer surface (read, for example, the electrically heated forin seal pattern 7 is exchangeably attached rectangular plate, which is delimited ralitileii-like on the two long sides and one transverse side by raised webs 8 , which are electrically heatable and are provided with some fine corrugation 9 on their jacket surface.

Die beiden Zylinder i und 6 sind in ihrem Umlauf so zueinander eingestellt und der .'#J)stand der genannten Stege so bemessen, daß letztere jeweils auf die Längskanten und die Bodenkante des Beiltelzuschnittes treffen, so daß durcli deren Wärme- und Druckwirkung eine fleißverklehting bzw. Versiegelung an den genannten Kanten des herzustellenden Beutels erfolgt.The two cylinders i and 6 are so adjusted in their rotation to each other and the. '# J) stand of the mentioned webs are dimensioned so that the latter meet the longitudinal edges and the bottom edge of the beeille blank, so that due to their heat and pressure effect, a fleißverklehting or sealing takes place at the named edges of the bag to be produced.
