The pack (8) is inserted through a first slot (10) and the papers are received one after the other through a second slot (14, 16, 18). The slot 10 is closed by an adhesive strip (20)

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, Verfahren, Vorrichtungen und Beutel weiterzuentwickeln.Proceeding from this, the invention is based on the object of further developing methods, devices and bags.

Ein Verfahren zur Lösung dieser Aufgabe weist die Merkmale des Anspruchs 1 auf. Es ist demnach vorgesehen, dass die fortlaufende Materialbahn gefaltet wird, sodass eine wenigstens teilweise zweilagige fortlaufende Materialbahn entsteht, und dass danach die beiden Lagen der fortlaufenden Materialbahn durch Anbringung wenigstens einer Verbindungsnaht miteinander verbunden werden, wobei die Verbindungsnaht vorzugsweise unterbrochen und in Längsrichtung der Materialbahn verläuft, und dass danach eine Lage der doppellagigen fortlaufenden Materialbahn durch einen vorzugsweise durchgehenden Trennschnitt aufgetrennt wird, zur Bildung der Öffnung für die Beutel, und dass danach Längs- und/oder Quernähte für die Beutel an der fortlaufenden Materialbahn angebracht werden und dass danach die Beutel aus der fortlaufenden Materialbahn vereinzelt werden.A method for solving this problem has the features of claim 1. It is therefore provided that the continuous material web is folded so that an at least partially two-layer continuous material web is created, and that then the two layers of the continuous material web are connected to one another by applying at least one connecting seam, the connecting seam preferably being interrupted and running in the longitudinal direction of the material web , and that a layer of the double-layer continuous material web is then separated by a preferably continuous severing cut to form the opening for the bags, and that longitudinal and / or transverse seams for the bags are then attached to the continuous material web and that the bags are then removed the continuous web of material are separated.

Durch die Verwendung einer zweilagigen Materialbahn ist es möglich, dass die Innenseite der Beutellasche eine Bedruckung aufweist, selbst wenn die Materialbahn nur einseitig bedruckt ist. Somit wird auf einfache und kostengünstige Weise der Gestaltungsspielraum erweitert bzw. mehr Fläche für gestalterische oder informative Zwecke zur Verfügung gestellt. Es hat sich dabei überraschend herausgestellt, dass es aus verschiedenen Gründen vorteilhafter ist, eine doppellagige Materialbahn zu verwenden, die einseitig bedruckt ist, als eine einlagige Materialbahn, die auf beiden Seiten bedruckt ist.By using a two-layer material web, it is possible for the inside of the bag flap to have printing, even if the material web is only printed on one side. In this way, the scope for design is expanded in a simple and inexpensive manner or more space is made available for design or informational purposes. It has surprisingly been found that for various reasons it is more advantageous to use a double-layer material web that is printed on one side than a single-layer material web that is printed on both sides.

Gemäß einer bevorzugten Weiterentwicklung kann vorgesehen sein, dass eine vorzugsweise obere bzw. innenseitige Lage der doppellagigen fortlaufenden Materialbahn von der anderen Lage beabstandet wird, insbesondere durch Anheben, und dass ein Verschlussmittel für die Tasche der Beutel im Bereich der Öffnung angebracht wird, um die Öffnung der Beutel mehrfach öffnen und schließen zu können.According to a preferred further development it can be provided that a preferably upper or inner layer of the double-layer continuous material web is spaced from the other layer, in particular by lifting, and that a closure means for the bag of the bag is attached in the area of the opening around the opening to be able to open and close the bag several times.

In diesem Zusammenhang bietet es sich insbesondere an, dass ein Materialstreifen zur Bildung eines Ziplocks an der fortlaufenden Materialbahn angebracht wird, und dass spätere Enden des Materialstreifens im Bereich von seitlichen Rändern der Beutel verschweißt werden, nachdem das Ziplock wenigstens partiell geöffnet wurde.In this context, it is particularly advisable that a material strip is attached to the continuous material web to form a ziplock, and that later ends of the material strip are welded in the area of the side edges of the bag after the zip lock has been at least partially opened.

In einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass Quernähte der Beutel angebracht werden, nachdem der Materialstreifen für die Ziplocks angebracht wurde und bevor die späteren Enden des Materialstreifens verschweißt werden.In a preferred embodiment of the invention it is provided that transverse seams of the bags are applied after the material strip for the zip locks has been attached and before the later ends of the material strip are welded.

Eine Besonderheit kann darin bestehen, dass Leimstreifen für eine Peel-Seal-Naht des Beutels an der fortlaufenden Materialbahn vorgesehen sind und durch das Falten der Materialbahn zur Anlage aneinander gebracht werden, und dass nach dem Befüllen der Beutel mit Tabak als Packungsinhalt, die Peel-Seal-Naht im Bereich der Öffnung des Beutels verschlossen wird.A special feature can be that strips of glue are provided for a peel-seal seam of the bag on the continuous material web and are brought into contact with one another by folding the material web, and that after the bag has been filled with tobacco as the package content, the peel- Seal seam in the area of the opening of the bag is closed.

Von besonderem Vorteil kann es sein, wenn die beiden Lagen der fortlaufenden Materialbahn durch zwei parallele Verbindungsnähte miteinander verbunden werden, wobei eine Verbindungsnaht entlang eines Randes der doppellagigen fortlaufenden Materialbahn und eine zweite Verbindungsnaht mit Abstand zur ersten Verbindungsnaht oberhalb der später herzustellenden Öffnung angebracht wird, und dass danach der Trennschnitt mit vorzugsweise geringem Abstand unterhalb der zweiten Verbindungsnaht angebracht wird, insbesondere derart, dass sich in der durch den Trennschnitt aufgetrennte Lage der fortlaufenden Materialbahn beim Anbringen des Trennschnitts möglichst wenig Falten bilden.It can be particularly advantageous if the two layers of the continuous material web are connected to one another by two parallel connecting seams, one connecting seam being attached along an edge of the double-layer continuous material web and a second connecting seam at a distance from the first connecting seam above the opening to be made later, and that the severing cut is then made at a preferably small distance below the second connecting seam, in particular in such a way that as few folds as possible are formed in the layer of the continuous material web severed by the severing cut when the severing cut is made.

Entsprechend kann es von Vorteil sein, wenn die durch den Trennschnitt aufzutrennende Lage der fortlaufenden Materialbahn niedergehalten wird, insbesondere durch ein Rollen zu beiden Seiten des Trennschnitts, sodass eine Bildung von Falten in der Lage beim Anbringen des Trennschnitts entgegengewirkt wird.Accordingly, it can be advantageous if the layer of the continuous material web to be separated by the separating cut is held down, in particular by rolling on both sides of the separating cut, so that the formation of folds in the position when the separating cut is made is counteracted.

Eine weitere Besonderheit, für die auch unabhängig von den anderen Merkmalen Schutz beansprucht wird, kann darin bestehen, dass ein weiterer Trennschnitt in der anderen Lage der fortlaufenden Materialbahn angebracht wird, nämlich im Bereich der Beutellasche, zur Bildung einer weiteren Tasche für Raucherartikel, die (auch) bei geschlossener Beutellasche von außen zugänglich ist.Another special feature, for which protection is also claimed independently of the other features, can be that another separating cut is made in the other layer of the continuous web of material, namely in the area of the bag flap, to form another pocket for smokers' articles, which ( also) is accessible from the outside when the bag flap is closed.

Eine Vorrichtung zur Lösung der eingangs genannten Aufgabe weist die Merkmale des Anspruchs 9 auf. Es ist demnach vorgesehen, dass:

  • in einer Faltstation die fortlaufende Materialbahn gefaltet wird, sodass eine wenigstens teilweise zweilagige fortlaufende Materialbahn entsteht,
  • in einer der Faltstation folgenden Verbindungsstation die beiden Lagen der fortlaufenden Materialbahn durch Anbringung wenigstens einer Verbindungsnaht miteinander verbunden werden, wobei die Verbindungsnaht vorzugsweise unterbrochen und in Längsrichtung der Materialbahn verläuft,
  • in einer der Faltstation folgenden Schneidstation eine Lage der doppellagigen fortlaufenden Materialbahn durch einen vorzugsweise durchgehenden Trennschnitt aufgetrennt wird, zur Bildung der Öffnung der Beutel,
  • in einer Siegelstation Längs- und/oder Quernähte für die Beutel an der fortlaufenden Materialbahn angebracht werden,
  • in einer Vereinzelungsstation die Beutel aus der fortlaufenden Materialbahn abgetrennt werden.
A device for solving the aforementioned object has the features of claim 9. It is therefore provided that:
  • the continuous material web is folded in a folding station so that an at least partially two-ply continuous material web is created,
  • in a connecting station following the folding station, the two layers of the continuous material web are connected to one another by attaching at least one connecting seam, the connecting seam preferably being interrupted and running in the longitudinal direction of the material web,
  • in a cutting station following the folding station, a layer of the double-layer continuous material web is separated by a preferably continuous separating cut to form the opening of the bags,
  • longitudinal and / or transverse seams for the bags are attached to the continuous material web in a sealing station,
  • the bags are separated from the continuous web of material in a separation station.

Die Erfindung befasst sich mit der Herstellung von Beuteln 10 aus Folie. Die Beutel 10 verfügen über eine Tasche 11 zur Aufnahme des Beutelinhalts. Bei diesem handelt sich im vorliegenden Fall um eine Portion 12 auf geschnittenem Tabak. Der Beutelinhalt kann über eine Öffnung 13 in die Tasche 11 eingefüllt werden, bzw. durch diese später entnommen werden. Eine Beutellasche 14 dient zum Verschließen bzw. Verdecken der Öffnung 13. In Schließstellung wird die Beutellasche 14 durch ein Verschlussmittel, insbesondere ein Verschlusstape 15 am Beutel 10 gesichert. Ferner kann eine (Steuer-) Banderole 16 am Beutel 10 angebracht sein (Fig. 1).The invention is concerned with the manufacture of bags 10 from film. The bags 10 have a pocket 11 for receiving the contents of the bag. In the present case, this is a portion 12 on cut tobacco. The contents of the bag can be filled into the bag 11 through an opening 13 or removed later through this. A bag flap 14 is used to close or cover the opening 13. In the closed position, the bag flap 14 is secured to the bag 10 by a closure means, in particular a closure tape 15. Furthermore, a (tax) banderole 16 can be attached to the bag 10 ( Fig. 1 ).

Im Bereich der Tasche 11 verfügt der Beutel 10 über eine Vorderwand 17 und eine Rückwand 18. Die Öffnung ist durch ein Ziplock 19 mehrfach verschließbar sowie durch eine vorzugsweise unterhalb des Ziplocks 19 angeordnete Peel-Seal-Naht 20. Es ist auch denkbar, dass auf eines der beiden Verschlussmittel verzichtet wird. Seitlich sind die Vorderwand 17 und die Rückwand 18 durch Seitennähte 21 miteinander verbunden. Die Beutellasche 14 ist in Verlängerung der Rückwand 18 gebildet.In the area of the pocket 11, the bag 10 has a front wall 17 and a rear wall 18. The opening can be closed several times by a zip lock 19 and by a peel-seal seam 20 preferably arranged below the zip lock 19. It is also conceivable that on one of the two closure means is dispensed with. At the side, the front wall 17 and the rear wall 18 are connected to one another by side seams 21. The bag flap 14 is formed as an extension of the rear wall 18.

Der Beutel 10 wird aus einer fortlaufenden Materialbahn 22 aus Folie gefertigt. Eine Besonderheit besteht darin, dass die fortlaufende Materialbahn 22 in einem ersten Schritt derart gefaltet wird, dass eine doppellagige, fortlaufende Materialbahn 22 gebildet wird.The bag 10 is made from a continuous web 22 of film. A special feature is that the continuous material web 22 is folded in a first step in such a way that a double-layer, continuous material web 22 is formed.

Im vorliegenden Fall ist die Materialbahn 22 komplett doppellagig ausgebildet (über die gesamte Breite der Materialbahn 22). Denkbar sind natürlich auch Varianten, bei denen die Materialbahn 22 so gefaltet wird, dass sie nur teilweise doppellagig ausgebildet ist. Denkbar sind ferner Lösungen, bei denen die Materialbahn mehr als zwei Lagen aufweist.In the present case, the material web 22 is completely double-layered (over the entire width of the material web 22). Variants are of course also conceivable where the web of material 22 is folded so that it is only partially formed with two layers. Solutions are also conceivable in which the material web has more than two layers.

Die Materialbahn 22 wird entlang einer Faltkante 23 gefaltet, die bei den späteren Beuteln 10 im Bereich des Bodens zwischen der Vorderwand 17 und der Rückwand 18 angeordnet ist. Eine untere Lage 24 bzw. hintere Lage der Materialbahn 22 bildet demnach die Rückwand 18 der Tasche 11 und eine Rückwand 25 der Beutellasche 14. Eine obere Lage 26 bzw. vordere Lage der Materialbahn 22 bildet entsprechend die Vorderwand 17 der Tasche 11 und eine Vorderwand 27 der Beutellasche 14.The material web 22 is folded along a fold edge 23 which, in the case of the later bags 10, is arranged in the area of the bottom between the front wall 17 and the rear wall 18. A lower layer 24 or rear layer of the material web 22 accordingly forms the rear wall 18 of the pocket 11 and a rear wall 25 of the bag flap 14. An upper layer 26 or front layer of the material web 22 correspondingly forms the front wall 17 of the pocket 11 and a front wall 27 the bag flap 14.

Das Falten der Materialbahn 22 erfolgt in einer Faltstation 28, in der die in einer aufrechten Ebene einlagig zugeführte Materialbahn 22 mit Hilfe eines Faltdreiecks 29 auf sich selbst gefaltet und in Verbindung mit einer horizontalen Umlenkrolle 30 in eine horizontale Ebene umgelenkt wird (Fig. 7). Dabei werden auch zwei Leimstreifen 58, 59 für die Peel-Seal-Naht 20 zur Anlage aneinander gebracht.The material web 22 is folded in a folding station 28, in which the material web 22, which is fed in a single layer in an upright plane, is folded onto itself with the help of a folding triangle 29 and, in conjunction with a horizontal deflection roller 30, is deflected into a horizontal plane ( Fig. 7 ). Two strips of glue 58, 59 for the peel-seal seam 20 are also brought to bear against one another.

Im nächsten Schritt werden die beiden Lagen 24, 26 der Materiabahn 22 in einer Verbindungsstation miteinander verbunden, bzw. aneinander fixiert, bevor ein Trennschnitt durch die Materialbahn 22 durchgeführt wird.In the next step, the two layers 24, 26 of the material web 22 are connected to one another or fixed to one another in a connecting station before a separating cut is made through the material web 22.

Im vorliegenden Fall werden die beiden Lagen 24, 26 durch zwei Rollsonotroden 31, 32 miteinander verschweißt, wodurch Längsnähte 33, 34 gebildet werden, die in Längsrichtung der Materialbahn 22 gerichtet verlaufen. Natürlich können auch andere Methoden gewählt werden, um die beiden Lagen 24, 26 miteinander zu verbinden, bspw. durch Verklebung.In the present case, the two layers 24, 26 are welded to one another by two roller sonotrodes 31, 32, whereby longitudinal seams 33, 34 are formed which run in the longitudinal direction of the material web 22. Of course, other methods can also be selected in order to connect the two layers 24, 26 to one another, for example by gluing.

Im vorliegenden Fall sind die Längsnähte 33, 34 so angeordnet, dass die Lagen 24, 26 im Bereich eines oberen Randes 35 der Beutellasche 14 und im Bereich eines unteren Randes 36 bzw. Endes der Beutellasche 14 miteinander verbunden werden.In the present case, the longitudinal seams 33, 34 are arranged such that the layers 24, 26 are connected to one another in the area of an upper edge 35 of the bag flap 14 and in the area of a lower edge 36 or end of the bag flap 14.

Eine Besonderheit hinsichtlich der Anbringung der Längsnähte 33, 34 besteht darin, dass diese sich nicht durchgehend über die fortlaufende Materialbahn 22 erstrecken, sondern mit Abstand zu Seitennähten 37 der Beutellasche 14 enden, die in einem späteren Fertigungsschritt angebracht werden. Auf diese Weise werden zwischen den Längsnähten 33, 34 und den Seitennähten 37 der Beutellasche 14 Entlüftungsöffnungen 38 gebildet, durch die Luft aus dem Raum zwischen den beiden Lagen 24, 26 entweichen kann. Natürlich ist es auch denkbar, dass zunächst die Seitennähte 37 angebracht werden und erst später die Längsnähte 33, 34.A special feature with regard to the attachment of the longitudinal seams 33, 34 is that they do not extend continuously over the continuous material web 22, but end at a distance from the side seams 37 of the bag flap 14, which are attached in a later manufacturing step. In this way, ventilation openings 38 are formed between the longitudinal seams 33, 34 and the side seams 37 of the bag flap 14, through which air can escape from the space between the two layers 24, 26 can. Of course, it is also conceivable that the side seams 37 are applied first and the longitudinal seams 33, 34 only later.

Nach der Fixierung der beiden Lagen 24, 26 aneinander, wird in einer Schneidstation ein fortlaufender, durchgehender Trennschnitt 39 an der fortlaufenden Materialbahn 22 ausgebildet. Der Trennschnitt 39 betrifft allerdings nur einen Teil der Lagen der Materialbahn 22, im vorliegenden Fall die obere Lage 26 der Materialbahn 22.After the two layers 24, 26 have been fixed to one another, a continuous, continuous separating cut 39 is formed on the continuous material web 22 in a cutting station. The separating cut 39, however, only affects a part of the layers of the material web 22, in the present case the upper layer 26 of the material web 22.

Der Trennschnitt 39 wird mittels einer Messerklinge 40 durchgeführt, die an einem Messerhalter 41 angeordnet ist. Damit die Messerklinge 40 nur die obere Lage 26 der Materialbahn 22 auftrennen kann, ist unterhalb der Messerklinge 40 ein Trennschwert 42 angeordnet, welches die beiden Lagen 24, 26 voneinander beabstandet.The severing cut 39 is made by means of a knife blade 40 which is arranged on a knife holder 41. So that the knife blade 40 can only cut the upper layer 26 of the material web 22, a separating sword 42 is arranged below the knife blade 40, which separates the two layers 24, 26 from one another.

Das Trennschwert 42 ist im vorliegenden Fall als plattenförmiges Organ ausgebildet, welches sich im Grundriss in Transportrichtung der Materialbahn 22 und quer hierzu gegenüber der Messerklinge 40 erstreckt (Fig. 12).In the present case, the separating sword 42 is designed as a plate-shaped organ which, in plan, extends in the transport direction of the material web 22 and transversely to this opposite the knife blade 40 ( Fig. 12 ).

Bei Bedarf kann die Messerklinge 40 auch optional beheizt ausgebildet sein.If necessary, the knife blade 40 can also optionally be designed to be heated.

Beiderseits der Längsachse des Trennschnitts 39 sind zu beiden Seiten der doppellagigen Materialbahn 22 angetriebene Rollen 43 angeordnet, welche einem Verziehen der Materialbahn 22 bei der Ausbildung des Trennschnitts 39 wenigstens entgegenwirken sollen. Darüber hinaus wird der Trennschnitt 39 mit geringem Abstand zur Längsnaht 34 ausgebildet, sodass der Gefahr einer Faltenbildung in der Materialbahn 22 wenigstens entgegengewirkt wird.On both sides of the longitudinal axis of the separating cut 39, driven rollers 43 are arranged on both sides of the double-layer material web 22, which are intended to at least counteract any warping of the material web 22 when the separating cut 39 is formed. In addition, the separating cut 39 is formed at a small distance from the longitudinal seam 34, so that the risk of wrinkling in the material web 22 is at least counteracted.

Im nächsten Schritt wird das Ziplock 19 für die Beutel 10 im Bereich des Trennschnitts 39 angebracht (Fig. 8). Hierzu wird ein fortlaufender Materialstreifen 44 für das Ziplock 19 an der Materialbahn 22 angebracht. Der Materialstreifen 44 wird über eine Umlenkrollen 45 zugeführt und dann in seine beiden Profilstreifen 46, 47 aufgeteilt, die jeweils an einer Lage 24, 26 der Materialbahn 22 angebracht werden. Dies erfolgt auf bekannte Weise mit Hilfe von Sonotroden 48. Danach werden die beiden Profilstreifen 46, 47 mit Hilfe eines Paares von Rollen 49 wieder vereinigt.In the next step, the zip lock 19 for the bags 10 is attached in the area of the separating cut 39 ( Fig. 8 ). For this purpose, a continuous strip of material 44 for the zip lock 19 is attached to the material web 22. The material strip 44 is fed via a deflection roller 45 and then divided into its two profile strips 46, 47, which are each attached to a layer 24, 26 of the material web 22. This is done in a known manner with the aid of sonotrodes 48. The two profile strips 46, 47 are then reunited with the aid of a pair of rollers 49.

In der nächsten Station werden die Seitennähte 21, 37 mit Hilfe entsprechender Sonotroden 50 angebracht. Anschließend wird das Ziplock 19 wieder geöffnet und danach die seitlichen Enden 51 des Ziplocks für jeden Beutel 10 verschweißt. Auch hierzu kommt im gezeigten Ausführungsbeispiel wieder eine Sonotrode 52 zum Einsatz.In the next station, the side seams 21, 37 are made with the aid of corresponding sonotrodes 50. Then the zip lock 19 is opened again and then the lateral ends 51 of the zip lock for each bag 10 are welded. A sonotrode 52 is also used for this in the exemplary embodiment shown.

Im Anschluss werden die Beutel 10 vereinzelt, befüllt und das Ziplock 19 verschlossen und die Peel-Seal-Naht 20 durch Ultraschallsiegelung verschlossen (Fig. 9).The bags 10 are then separated, filled and the zip lock 19 closed and the peel-seal seam 20 closed by ultrasonic sealing ( Fig. 9 ).

Eine weitere Besonderheit des in Fig. 1 bis 3 gezeigten Beutels 10 besteht in einer weiteren Tasche 53, die in der doppellagigen Beutellasche 14 gebildet ist. Hierzu weist die Beutellasche 14 einen außenseitigen Einschnitt 54 auf, der als Öffnung zur Tasche 53 dient. In der Tasche 53 kann bei Bedarf ein Zubehörartikel platziert werden, wie beispielsweise ein Päckchen 55 mit Zigarettenpapier. Der Einschnitt 54 wird auf der anderen Seite der Materialbahn 22 angebracht als der Trennschnitt 39, nämlich der Rückwand 25 der Beutellasche 14. Auf diese Weise ist der Zubehörartikel auch in Schließstellung der Beutellasche 14 erreichbar. Zudem bleibt so die Innenseite bzw. Vorderwand 27 der Beutellasche 14 intakt und kann so beim Rollen des Tabaks benutzt werden.Another special feature of the in Figs. 1 to 3 The bag 10 shown consists of a further bag 53 which is formed in the double-layer bag flap 14. For this purpose, the bag flap 14 has an incision 54 on the outside, which serves as an opening to the pocket 53. An accessory, such as a packet 55 of cigarette paper, can be placed in the pocket 53 if required. The incision 54 is made on the other side of the material web 22 than the separating cut 39, namely the rear wall 25 of the bag flap 14. In this way, the accessory article can also be reached when the bag flap 14 is in the closed position. In addition, the inside or front wall 27 of the bag flap 14 remains intact and can thus be used when rolling the tobacco.

Wie in Fig. 1 gezeigt kann der Einschnitt 54 quer oder längs an der Beutellasche 14 angeordnet sein, wobei in der Regel ein einzelner Einschnitt 54 also entweder quer oder längs ausreicht. Im Bereich der seitlichen Enden des Einschnitts 54 verläuft dieser gekrümmt zur Längsrichtung desselben, wodurch einem weiteren Einreißen der Rückwand 25 wenigstens entgegengewirkt wird.As in Fig. 1 As shown, the incision 54 can be arranged transversely or longitudinally on the bag flap 14, whereby a single incision 54 either transversely or longitudinally is usually sufficient. In the area of the lateral ends of the incision 54, the latter is curved in relation to the longitudinal direction of the latter, as a result of which further tearing of the rear wall 25 is at least counteracted.

Die Anbringung der Einschnitte 54 erfolgt bei der Verarbeitung der fortlaufenden Materialbahn 22. Denkbar ist die Anbringung der Einschnitte 54 vor dem Umfalten, also noch im Bereich der aufrechten Transportbahn (Fig. 6). Denkbar ist auch, dass die Einschnitte nach dem Umfalten angebracht werden, beispielsweise nach Fixierung der beiden Lagen 24, 26 aneinander und bevor der Trennschnitt 39 angebracht wird. Es hat sich gezeigt, dass ein längs gerichteter Einschnitts 54 besser vor dem Umfalten der Materialbahn 22 angebracht werden kann, wohingegen ein quergerichteter Einschnitt 54 besser später, nämlich vor der Anbringung des Trennschnitts 39 angebracht wird.The incisions 54 are made during the processing of the continuous material web 22. It is conceivable that the incisions 54 may be made before folding over, i.e. still in the area of the upright transport path ( Fig. 6 ). It is also conceivable that the incisions are made after folding over, for example after the two layers 24, 26 have been fixed to one another and before the separating cut 39 is made. It has been shown that a longitudinally directed incision 54 can be made better before the material web 22 is folded over, whereas a transversely directed incision 54 is better made later, namely before the separating cut 39 is made.

Eine Möglichkeit zur Anbringung eines Einschnitts 54 ist in Fig. 10 gezeigt. Dabei werden die Rückwand 25 und die Vorderwand 27 der Beutellasche 14 im Bereich von Vakuumkammern 56, 57 auf Abstand gebracht, sodass mit Hilfe einer Messerklinge 58 der Einschnitt 54 in der Rückwand 25 angebracht werden kann, ohne dass die Vorderwand 27 beschädigt wird.One way of making an incision 54 is in FIG Fig. 10 shown. The rear wall 25 and the front wall 27 of the bag flap 14 are spaced apart in the area of the vacuum chambers 56, 57 so that the incision 54 can be made in the rear wall 25 with the aid of a knife blade 58 without the front wall 27 being damaged.

Fig. 4 und 5 zeigen eine Variante des Beutels 10 ohne zusätzliche Tasche 53 in der Beutellasche 14. Hierbei wurde auch auf die Längsnähte 33, 34 verzichtet, sodass die Rückwand 25 und die Vorderwand 27 der Beutellasche 14 nur über die Seitennähte 37 verbunden sind. In diesem Fall müssen die beiden Lagen 24, 26 zunächst über eine oder mehrere Seitennähte 21, 37 aneinander fixiert werden, bevor der Trennschnitt 39 ausgebildet wird. Figures 4 and 5 show a variant of the bag 10 without an additional pocket 53 in the bag flap 14. The longitudinal seams 33, 34 have also been dispensed with, so that the rear wall 25 and the front wall 27 of the bag flap 14 are only connected via the side seams 37. In this case, the two layers 24, 26 must first be fixed to one another via one or more side seams 21, 37 before the separating cut 39 is formed.
