Description

Die Erfindung betrifft eine Beutelmaschine zur Herstellung von Beuteln aus Papiermaterial nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Herstellung von Beuteln aus Papiermaterial nach dem Oberbegriff des Anspruchs 9.The invention relates to a bag machine for the production of bags of paper material according to the preamble of claim 1 and a method for the production of bags of paper material according to the preamble of claim 9.

Derartige Beutelmaschinen sind seit Längerem bekannt. Die Offenlegungsschrift DE 35 29 746 A1 und die Patentschrift GB 918 381 geben einen guten Überblick über solche Maschinen. Auch Herstellungsverfahren für Papierbeutel sind hier beschrieben.Such bagging machines have been known for some time. The publication DE 35 29 746 A1 and the patent GB 918,381 give a good overview of such machines. Also manufacturing methods for paper bags are described here.

Beutelmaschinen umfassen in der Regel zunächst eine Abwickeleinrichtung, in der bahnförmiges Papiermaterial abgezogen wird. Das Material wird dann in einer Transportrichtung der eigentlichen Beutelmaschine zugeführt. In einem ersten Bearbeitungsschritt, der in einer entsprechenden Station durchgeführt wird, wird das Bahnmaterial mit Querperforationen oder Querschnitten versehen, so dass Schwächungslinien entstehen. Hierzu ist in der Regel ein Schneid- und/oder Perforationswerkzeug auf einer rotierenden Welle aufgebracht. Dieses Werkzeug taucht in das bahnförmige Material, welches über eine Gegenwalze läuft, ein, wobei die Schwächungslinien entstehen. Entlang dieser Schwächungslinien lässt sich das Papiermaterial in Abschnitte trennen. Der Abstand zweier Schwächungslinien legt also die Länge des Beutels fest. Das Trennen in Abschnitte erfolgt in der Regel nach dem Durchlaufen einer Schlauchbildungsstation, in welcher die Seitenbereiche des bahnförmigen Papiermaterials unter Ausbildung eines Überlappungsbereiches umgeschlagen und in welcher die sich zugewandten Seiten des Überlappungsbereiches miteinander verbunden werden, beispielsweise durch Auftragen eines geeigneten Papierleims. Die auf diese Weise gebildete Längsnaht umfassende Wand des Schlauchmaterials wird in der Regel als obere Wand des Schlauches beziehungsweise des Schlauchabschnitts bezeichnet. Entsprechend wird die andere Wand als untere Wand bezeichnet. Weiterhin ist es möglich, Seitenfalten in den Schlauch einzulegen. Die Seitenfaltenbildung erfolgt bevorzugt zusammen mit der eigentlichen Schlauchbildung. Vor dem Zusammenlegen zum Schlauch muss für eine dauerhafte Verbindung der spätere Überlappungsbereich mit Klebstoff, beispielsweise Stärkeleim, belegt werden.Pouch machines usually initially comprise an unwinding device in which web-shaped paper material is withdrawn. The material is then fed in a transport direction of the actual bag machine. In a first processing step, which is carried out in a corresponding station, the web material is provided with transverse perforations or cross sections, so that lines of weakness arise. For this purpose, a cutting and / or perforation tool is usually applied to a rotating shaft. This tool dips into the sheet-like material, which runs over a counter roll, whereby the lines of weakness arise. Along these lines of weakness, the paper material can be separated into sections. The distance between two lines of weakness thus determines the length of the bag. The separation into sections is usually carried out after passing through a hose forming station, in which the side regions of the web-shaped paper material to form an overlap region turned over and in which the facing sides of the overlapping area are joined together, for example by applying a suitable paper glue. The wall of the tubing comprising the longitudinal seam formed in this way is generally referred to as the upper wall of the tubing or of the tubing section. Accordingly, the other wall is referred to as the bottom wall. Furthermore, it is possible to insert gussets in the hose. The gusseting is preferably carried out together with the actual tube formation. Prior to folding into the hose, the subsequent overlap area must be covered with adhesive, such as starch glue, for a permanent connection.

Wurde ein Schlauch gebildet, so wird folglich der Schlauch in der Trenneinrichtung entlang der Schwächungslinien zu Schlauchabschnitten vereinzelt.If a hose has been formed, the hose in the separating device is consequently separated along the weakening lines to form hose sections.

Eine einzelne Schwächungslinie kann lediglich Perforationen aufweisen, sie kann aber gemäß der eingangs erwähnten DE 35 29 746 A1 auch Glattschnitte umfassen. Eine Schwächungslinie umfasst dabei im Regelfall mehrere Abschnitte, die in Transportrichtung gesehen verschiedene Positionen einnehmen, also gegeneinander versetzt sind. Der Verlauf der Schwächungslinie ist dabei so gewählt, dass das voraus laufende Ende der unteren Wand das voraus laufende Ende der oberen Wand überragt. Auf diese Weise ist es möglich, im weiteren Verarbeitungsprozess die untere Wand auf die obere Wand umzufalten, so dass die Innenseite der unteren Wand auf der Außenseite der oberen Wand zu liegen kommt. Zur eigentlichen Bodenbildung wird der umzufaltende Teil vor der Faltung mit Leim versehen. Beim nachlaufenden, im späteren Beutel offenen Ende überragt die obere Wand dann die untere Wand. Bei bestimmten Beuteln wird jedoch vor oder während des Vereinzelungsvorgangs zu einzelnen Schlauchabschnitten zusätzlich noch ein Abschnitt der oberen Wand entfernt, so dass auch beim nachlaufenden Ende die untere Wand die obere Wand überragt. Der die andere Wand überragende Teil der einen Wand wird als Lasche bezeichnet. Im Oberbegriff des Anspruchs 1 wird die Wand, deren nachlaufendes Ende die Lasche aufweist, als erste Wand bezeichnet, wobei dies unabhängig davon gelten soll, ob die Wand die obere oder die untere Wand ist.A single line of weakness can only have perforations, but it can according to the above-mentioned DE 35 29 746 A1 also include smooth cuts. As a rule, a weakening line comprises a plurality of sections which, as seen in the transport direction, occupy different positions, ie are offset from one another. The course of the weakening line is chosen so that the forward end of the lower wall projects beyond the leading end of the upper wall. In this way it is possible, in the further processing process, to fold over the lower wall onto the upper wall, so that the inner side of the lower wall comes to rest on the outer side of the upper wall. For the actual bottoming the part to be folded is provided with glue before folding. At the trailing, open in the later bag end, the upper wall then dominates the lower wall. For certain bags, however, a section of the upper wall is additionally removed before or during the separation process to individual tube sections, so that even at the trailing end of the lower wall projects beyond the upper wall. The part of the one wall projecting beyond the other wall is called a tab. In the preamble of claim 1, the wall whose trailing end is the tab , referred to as the first wall, this being irrespective of whether the wall is the upper or the lower wall.

Auf die beschriebene Weise werden Beutel für zahlreiche Anwendungen hergestellt. Wird ein zu transportierendes Gut in die Beutel eingefüllt, so wird ein solcher Beutel in der Regel verschlossen. Häufig wird nach dem Befüllen das obere Ende oft einfach umgeschlagen, mehrfach umgeschlagen oder gerollt. Um ein selbstständiges Rückstellen dieser Faltungen zu vermeiden, werden diese Faltungen oft mit einem Klebefilmstreifen gesichert, der händisch aufgebracht wird. Man hat erkannt, dass Klebefilmstreifen oft nicht zur Hand sind, wenn sie benötigt werden. Es sind daher Beutel bekannt, auf denen eine Klebemittelfläche bereits beim Herstellungsprozess auf eine Außenwand aufgebracht wurde. Um einen solchen Beutel sicher zu verschließen, muss nur die die Klebemittelfläche schützende Schutzschicht, beispielsweise ein beschichtetes und daher wenig haftendes Papierstück, abgezogen werden und das offene Ende des Beutels einmal umgeschlagen werden, so dass die Außenwand anschließend auf sich selbst aufliegt oder die Lasche auf der Klebemittelfläche aufliegt. Dabei ist darauf zu achten, dass das Ende des Beutels die Klebemittelfläche gerade genau überdeckt. Ist das Ende zu kurz umgefaltet worden, sind Bereiche der Klebemittelfläche nicht abgedeckt. Ist das Ende hingegen zu weit umgefaltet worden, wird das Ende selbst nicht fixiert. Daher kann der Beutel ungewollt wieder geöffnet werden, wenn er beispielsweise an anderen Gegenständen hängen bleibt.In the manner described, bags are produced for numerous applications. If a good to be transported filled in the bag, such a bag is usually closed. Often, after filling, the upper end is often simply turned over, folded several times or rolled. In order to avoid an independent resetting of these folds, these folds are often secured with an adhesive film strip which is applied by hand. It has been recognized that adhesive film strips are often out of reach when needed. Therefore, bags are known on which an adhesive surface has already been applied to an outer wall during the manufacturing process. In order to securely close such a bag, only the protective layer protecting the adhesive surface, for example a coated piece of paper that has little adherence, must be peeled off and the open end of the bag must be turned once so that the outer wall subsequently rests on itself or on the flap the adhesive surface rests. It is important to ensure that the end of the bag just exactly covers the adhesive surface. If the end has been folded over too short, areas of the adhesive surface are not covered. If, on the other hand, the ending has been folded too far, the end itself is not fixed. Therefore, the bag can be unintentionally reopened, for example, when it gets stuck on other objects.

Soll der Beutel also korrekt verschlossen werden, so ergibt sich im Wesentlichen nur ein einziges Format des verschlossenen Beutels. Dies ist allerdings häufig unerwünscht, wenn der Beutel nur zum Teil gefüllt ist. In diesem Fall ist es also gewünscht, das Ende soweit umlegen zu können, dass das Format des befüllten Beutels nicht größer als notwendig ist. Dies ist allerdings mit Beuteln des Standes der Technik nicht möglich, wenn diese die Möglichkeit bieten sollen, sicher verschlossen zu werden.If the bag is to be closed correctly, essentially only one single format of the sealed bag results. However, this is often undesirable if the bag is only partially filled. In this case, it is therefore desirable to be able to relocate the end so far that the format of the filled bag is not larger than necessary. However, this is not possible with bags of the prior art, if they should offer the opportunity to be securely closed.

Die DE 43 14 685 A1 schlägt eine Maschine und ein Verfahren zur Herstellung von Beuteln vor, so dass die Beutel die genannten Nachteile nicht mehr aufweisen.The DE 43 14 685 A1 proposes a machine and a method for the production of bags, so that the bag no longer have the disadvantages mentioned.

Dabei ist in der Maschine eine Einrichtung zur Aufbringung von Klebemittelflächen auf das Papiermaterial vorgesehen, mit welcher jeweils eine Klebemittelfläche auf einen Bereich des Papiermaterials aufbringbar ist, welcher beim fertigen Beutel die der anderen Wand zugewandte Seite der Lasche ist. Mit anderen Worten wird die Klebemittelfläche auf der Seite der Lasche aufgebracht, die die Verlängerung der Innenseite der Wand darstellt. Mit dieser Maßnahme kann also die Klebemittelfläche direkt an dem offenen Ende angeordnet werden. Im Idealfall stößt ein Rand der Klebemittelfläche direkt an die Schnitt- oder Perforationskante des Beutels.In this case, a device for applying adhesive surfaces is provided on the paper material in the machine, with each of which an adhesive surface can be applied to a portion of the paper material, which is the other wall facing side of the tab in the finished bag. In other words, the adhesive surface is applied to the side of the tab that represents the extension of the inside of the wall. With this measure, therefore, the adhesive surface can be arranged directly at the open end. Ideally, an edge of the adhesive surface directly abuts the cut or perforated edge of the bag.

Die in der Schrift DE 43 14 685 hat jedoch den Nachteil, dass die Klebemittelflächen auf die fertigen Beutel aufzutragen sind. Dies ist jedoch sehr umständlich.The in the Scriptures DE 43 14 685 However, has the disadvantage that the adhesive surfaces are applied to the finished bag. This is very complicated.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung und ein Verfahren vorzuschlagen, mit denen sich die Klebemittelflächen sehr einfach auf das Material aufbringen lassen.The object of the present invention is therefore to propose an apparatus and a method with which the adhesive surfaces can be very easily applied to the material.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention, this object is solved by the features of the characterizing part of claim 1.

Die Anbringung der Klebemittelflächen kann grundsätzlich nach verschiedenen Herstellungsphasen des Beutels erfolgen. Lediglich nach der Schlauchbildung und vor der Vereinzelung des Schlauches zu Schlauchabschnitten ist das Aufbringen der Klebemittelflächen auf der Innenseite einer der beiden Wände nicht oder nur durch weitere konstruktive Elemente möglich. Während oder nach den nachfolgenden Herstellungsphasen und in den zugehörigen Bearbeitungsstationen ist das Aufbringen der Klebemittelflächen denkbar

  • Vereinzelung zu Schlauchabschnitten,
  • Vorbruch der Bodenfalzung
  • Leimauftrag für die Bodenleimung
  • Faltung des Bodens.
The attachment of the adhesive surfaces can in principle be carried out after different production phases of the bag. Only after the formation of the tube and before the separation of the tube into tube sections is it possible to apply the adhesive surfaces on the inside of one of the two walls or only by means of further structural elements. While or After the subsequent production phases and in the associated processing stations, the application of the adhesive surfaces is conceivable
  • Singulation to tube sections,
  • Pruning of the bottom fold
  • Glue application for floor sizing
  • Folding the floor.

Diese Auflistung ist nicht abschließend. Erfindungsgemäß ist jedoch vorgesehen, die Aufbringung der Klebemittelflächen vor der Schlauchbildung durchzuführen. Die Einrichtung zur Aufbringung der Klebemittelflächen ist also der Schlauchbildungseinrichtung vorgeordnet. Vor der Schlauchbildung liegt das Papiermaterial noch als Bahn vor, so dass sämtliche Bereiche dieser Bahn noch erreichbar sind. Insbesondere ist die gesamte Fläche erreichbar, die später die Innenseiten der Beutelwände bildet. Insbesondere wenn die vorliegende Bahn mit der späteren Außenseite der Beutel auf einer Fläche, beispielsweise die Umfangsfläche einer Führungswalze, aufliegt, kann die Klebemittelflächen sehr einfach auf die spätere Innenseite platziert werden. Auch ist die Position der Klebemittelflächen noch frei wählbar, da keine geometrischen Einschränkungen vorliegen. Insbesondere kann die Position quer zur Bahntransportrichtung variiert werden. Diese Variation ist vor allem dann wichtig, wenn Beutel produziert werden sollen, bei denen, wie eingangs beschrieben, die untere Wand sowohl am voraus laufenden als auch am nachlaufenden Ende die obere Wand überragt.This listing is not exhaustive. According to the invention, however, it is provided to carry out the application of the adhesive surfaces before the tube formation. The means for applying the adhesive surfaces is thus upstream of the tube forming device. Before the tube formation, the paper material is still present as a web, so that all areas of this web are still accessible. In particular, the entire surface can be reached, which later forms the insides of the bag walls. In particular, when the present web with the later outer side of the bag rests on a surface, for example, the peripheral surface of a guide roller, the adhesive surfaces can be easily placed on the later inside. Also, the position of the adhesive surfaces is still freely selectable, since there are no geometric restrictions. In particular, the position can be varied transversely to the web transport direction. This variation is particularly important when producing bags in which, as described above, the lower wall projects beyond the upper wall both at the front and at the trailing end.

Ein besonderes Merkmal bei der genannten Anordnung und Vorgehensweise also der Aufbringung der Klebemittelflächen vor der Schlauchbildung, ist, dass die Klebemittelflächen vor der Vereinzelung des Schlauches zu Schlauchabschrtitten innerhalb des Schlauches angeordnet sind.A special feature in the said arrangement and procedure, ie the application of the adhesive surfaces before the formation of the tube, is that the adhesive surfaces are arranged before the separation of the tube into Schlauchabschrtitten within the tube.

Während der Einbringung der Schwächungslinlen läuft die Bahn auf einer Walze, die einem Schneid- und/oder Perforationsmesser als Gegenlage dient. Daher ist es denkbar, während der Einbringung der Schwächungslinie auch die Klebemittelflächen aufzutragen.During the introduction of the weakening lines, the web runs on a roller which serves as a counter-blade to a cutting and / or perforating knife. Therefore, it is conceivable to apply the adhesive surfaces during the introduction of the weakening line.

Vorteilhaft ist es allerdings, die Einrichtung zur Aufbringung der Klebemittelflächen der Vorrichtung zur Einbringung der Schwächungslinie nachzuordnen. An einer solchen Stelle kann Anordnung einer Einrichtung zur Aufbringung der Klebemittelflächen optional erfolgen, also nur wenn der Bedarf für eine solche Einrichtung besteht. Dies kann auch nachträglich erfolgen. Insbesondere ist hier die genannte Einrichtung sehr einfach zu erreichen und daher sehr wartungsfreundlich.However, it is advantageous to rearrange the device for applying the adhesive surfaces of the apparatus for introducing the weakening line. At such a location arrangement of a device for applying the adhesive surfaces can optionally be done, so only if there is a need for such a device. This can also be done later. In particular, the said device is very easy to reach and therefore very easy to maintain.

Im Vorfeld der Schlauchbildung durchläuft das bahnförmige Papiermaterial eine Leimauftragseinrichtung, mit der eine Leimspur auf den späteren Überdeckungsbereich aufgetragen wird. Dabei läuft das Material über eine Walze, die die Gegenlage für den Leimauftrag darstellt. Hier kann auch die Einrichtung zur Aufbringung von Klebemittelflächen vorgesehen sein, die ebenfalls die Walze als Gegenlage nutzt. Daher ist es von besonderem Vorteil, die Einrichtung an dieser Stelle vorzusehen.In the run-up to the formation of the tube, the web-shaped paper material passes through a glue application device, with which a glue trace is applied to the later covering area. The material runs over a roller, which represents the counter layer for the glue application. Here, the device for applying adhesive surfaces may also be provided, which also uses the roller as a counter-surface. Therefore, it is of particular advantage to provide the device at this point.

Eine besonders bevorzugte Ausgestaltung der Erfindung beinhaltet, dass die Einrichtung zur Aufbringung von Klebemittelflächen mit dem der Vorrichtung zur Erzeugung der von Schwächungslinien synchronisiert ist. Dabei wird bei der Einbringung einer Schwächungslinie ein Startimpuls erzeugt. In Abhängigkeit von der Maschinengeschwindigkeit und der Entfernung der Einrichtung zur Aufbringung von Klebemittelflächen von der Position, an der die Schwächungslinie eingebracht wird, errechnet eine Steuereinrichtung den Zeitpunkt, zu dem Das Aufbringen der Klebemittelschicht gestartet und/oder beendet werden muss. Im Bedarfsfall ist auch die Größe der Klebemittelschicht zu berücksichtigen, beispielsweise wenn so genannte Etiketten verwendet werden sollen.A particularly preferred embodiment of the invention includes that the means for applying adhesive surfaces is synchronized with that of the device for generating the lines of weakness. In this case, a start pulse is generated when introducing a weakening line. Depending on the machine speed and the distance of the means for applying adhesive surfaces from the position at which the line of weakness is introduced, a control device calculates the time at which the application of the adhesive layer has to be started and / or terminated. If necessary, the size of the adhesive layer is taken into account, for example, when so-called labels are to be used.

Mit der eingangs beschriebenen Vorrichtung ist es, wie bereits angedeutet wurde, möglich, anstelle von Flachbeuteln auch Seitenfaltenbeutel zu produzieren. In diesem Fall wird die Klebemittelfläche bevorzugt in dem Bereich der Lasche aufgebracht, der nicht durch die Seitenfalten bedeckt ist. Dies ist also der von Seitenfalten freie Teil der Lasche. Bei gegebener Klebemittefflächengröße kann aber umgekehrt die Perforationskontur so gestaltet werden, dass sich im Bereich der Klebemittelfläche keine Seitenfalte befindet. Die Möglichkeit, die Klebemittelfläche auch auf den durch die Seitenfalten bedeckten Teil auszudehnen, ist jedoch ebenfalls realisierbar und nicht nachteilig. Es können dabei auch die Seitenfalten fixiert werden, was dem Beutelverschluss zusätzliche Haltbarkeit verleiht.With the device described above, it is possible, as already indicated, to produce side gusset bags instead of flat bags. In this case, the adhesive surface is preferably applied in the region of the tab which is not covered by the gussets. So this is the part of the flap that is free of gussets. For a given Klebemittefflächengröße but vice versa, the perforation contour so be designed that there is no gusset in the area of the adhesive surface. However, the possibility of extending the adhesive surface also on the part covered by the side folds, is also feasible and not detrimental. It can also be fixed gussets, which gives the bag closure extra durability.

In weiterer Ausgestaltung der Beutelmaschine sind zumindest Teile der Einrichtung zur Aufbringung von Klebemittelflächen querverschieblich. Dazu können zwei Führungen quer zur Transportrichtung der Bahn vorgesehen sein. Zur Bewegung kann eine motorisch angetriebene Spindel-Mutter-Kombination vorgesehen sein.In a further embodiment of the bag machine at least parts of the device for applying adhesive surfaces are transversely displaceable. For this purpose, two guides can be provided transversely to the transport direction of the web. For movement, a motor-driven spindle-nut combination can be provided.

Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.

Fig. 1 zeigt bahnförmiges Papiermaterial 1 vor der eigentlichen Schlauchbildung, welches in Transportrichtung x durch die Beutelmaschine geführt wird. In dieses Papiermaterial 1 sind bereits Perforationen 2 eingebracht worden, die im Wesentlichen quer zur Transportrichtung x verlaufen. Man erkennt, dass Abschnitte der Perforationen in Transportrichtung x an verschiedenen Positionen angeordnet sind. So ist der Abschnitt 2a gegenüber den Abschnitten 2b in Transportrichtung verschoben. Die in Längsrichtung verlaufenden Linien zeigen die Längsfalzkanten 3 an. In der Figur ist erkennbar, dass der Versatz der Abschnitte 2a und 2b im Bereich dieser Falzkanten erfolgt. Punktiert dargestellt sind noch die Falzlinien 4, um die das bahnförmige Material bei der Schlauchbildung gefaltet wird, wenn Seitenfaltenbeutel produziert werden sollen. Fig. 1 shows sheet-like paper material 1 before the actual tube formation, which is guided in the transport direction x through the bag machine. In this paper material 1 perforations 2 have already been introduced, which extend substantially transversely to the transport direction x. It can be seen that sections of the perforations in the transport direction x are arranged at different positions. Thus, the portion 2a is shifted relative to the sections 2b in the transport direction. The longitudinal lines indicate the Längsfalzkanten 3 at. It can be seen in the figure that the offset of the sections 2a and 2b takes place in the region of these folded edges. The fold lines 4, around which the web-shaped material is folded during tube formation when puncture-side bags are to be produced, are also shown in dotted lines.

Die Fläche 5 bezeichnet die Innenseite 5 der unteren Wand. Die Flächen 6a und 6b stellen nach der Schlauchbildung die Innenseite der oberen Wand dar, Im gezeigten Ausführungsbeispiel sind auf der Fläche 6a Klebemittelflächen 7 gezeigt. Die Klebemittelflächen 7 sind dabei so auf dem Papiermaterial angebracht, dass sie in Transportrichtung x gesehen vollständig vor dem Perforationsabschnitt 2b liegen. Es sollte zwischen dem Klebemittelfläche 7 und dem Abschnitt 2b allerdings auch nur relativ wenig Fläche sein, so dass Klebemittelfläche 7 und Abschnitt 2b aneinander grenzen. Eine Klebemittelfläche 7 kann zusätzlich oder alternativ auf der Fläche 6b angeordnet sein. Der Doppelpfeil y deutet an, dass die Klebemittelfläche bei Bedarf quer zur Transportrichtung x verschiebbar und damit an beliebigen Stellen anordenbar ist.The surface 5 denotes the inner side 5 of the lower wall. The surfaces 6a and 6b represent the inside of the upper wall after the formation of the tube. In the embodiment shown, adhesive surfaces 7 are shown on the surface 6a. The adhesive surfaces 7 are mounted on the paper material in such a way that, viewed in the transport direction x, they lie completely in front of the perforation section 2 b. However, it should also be relatively little surface between the adhesive surface 7 and the portion 2b, so that adhesive surface 7 and section 2b adjoin one another. An adhesive surface 7 may additionally or alternatively be arranged on the surface 6b. The double arrow y indicates that the adhesive surface can be displaced transversely to the transport direction x, if necessary, and can therefore be arranged at any desired location.

Die Figur 2 zeigt den Schlauchbildungsvorgang. Mittels geeigneter Führungselemente in der Beutelmaschine, beispielsweise mittels entsprechend gebogener Führungsbleche wird das bahnförmige Papiermaterial 1 umgeschlagen. Dazu werden die Bahnkanten 8a, 8b von den Führungselementen derart geführt, dass sie auf die Fläche 5 gelegt werden, wobei Faltungen entlang der Längsfalzkanten 3 entstehen. Das bedarfsweise Einlegen von Seitenfalten ist dem Fachmann bekannt und wird daher hier nicht näher beschrieben.The FIG. 2 shows the tube forming process. By means of suitable guide elements in the bag machine, for example by means of correspondingly curved guide plates, the sheet-like paper material 1 is turned over. For this purpose, the web edges 8a, 8b are guided by the guide elements so that they are placed on the surface 5, wherein folds along the Längsfalzkanten 3 arise. The need for inserting gussets is known in the art and therefore will not be described here.

Bei dem Umschlagen wird die Bahnkante 8b zuerst umgelegt, gefolgt von der Bahnkante 8a, so dass die Kante 8a nach erfolgter Schlauchbildung sichtbar bleibt. Denkbar ist es aber auch, dass zuerst die Kante 8a und anschließend die Kante 8b umgelegt wird. Bei der Draufsicht auf den soeben gebildeten Schlauch 9 fällt auf, dass der Perforationsabschnitt 2b sichtbar ist, da dieser in die nun oben liegende Wand eingebracht ist. An dieser oben liegenden Wand befindet sich nun auch die Klebemittelfläche 7. Da sie sich aber im Schlauchinneren befindet und in der Draufsicht nicht sichtbar ist, ist sie in der Figur 2 punktiert dargestellt. Der Perforationsabschnitt 2a ist nun ebenfalls nicht sichtbar, da die Fläche 5, in der sie eingebracht ist, nun durch die Flächen 6a und 6b bedeckt, so dass der Abschnitt 2a ebenfalls punktiert dargestellt ist. Aus der Figur 2 wird deutlich, dass vorteilhafterweise die Erstreckung der Klebemittelfläche 7 in Transportrichtung x maximal gleich der Differenz der Positionen der Abschnitte 2a und 2b ist. Auf diese Weise ist die Klebemittelfläche auf den Bereich der Lasche 10 beschränkt, was in den Figuren 3 und 4 deutlich wird.During the turnover, the web edge 8b is folded first, followed by the web edge 8a, so that the edge 8a remains visible after the hose is formed. It is also conceivable, however, that first the edge 8a and then the edge 8b is folded. In the plan view of the just formed tube 9 it is noticeable that the perforation section 2b is visible, since this is introduced into the wall now above. At this top wall is now also the adhesive surface 7. However, since it is inside the tube and is not visible in the plan view, it is in the FIG. 2 shown dotted. The perforation section 2a is now also not visible, since the surface 5 in which it is introduced, now covered by the surfaces 6a and 6b, so that the portion 2a is also shown dotted. From the FIG. 2 It is clear that advantageously the extent of the adhesive surface 7 in the transport direction x is at most equal to the difference in the positions of the sections 2a and 2b. In this way, the adhesive surface is limited to the region of the tab 10, which in the FIGS. 3 and 4 becomes clear.

Die Figur 3 zeigt den Schlauch 9, nach dem er zu Schlauchabschnitten vereinzelt worden ist. Diese Vereinzelung erfolgt in der Regel dadurch, dass der Schlauch durch einen ersten Walzenspalt geführt wird. Die Walzen eines weiteren Walzenspaltes, der in Transportrichtung folgt und mit mindestens einer Schlauchabschnittslänge von dem ersten Walzenspalt entfernt ist, werden mit höherer Geschwindigkeit als die Walzen des ersten Walzenspaltes angetrieben. Erfassen die Walzen des weiteren Walzenspaltes das voraus laufende Ende des Schlauches 9, so reißt dieser entlang der Schwächungslinie oder Perforation 2. Nach der Vereinzelung wird des voraus laufende Ende des Schlauchabschnitts, welches zumindest aus einer Verlängerung unteren Fläche 5 besteht, umgefaltet und auf der oberen Wand, die die Flächen 6a und 6b umfasst, fixiert.The FIG. 3 shows the tube 9, after which it has been separated into tube sections. This separation is usually carried out in that the tube is passed through a first nip. The rollers of a further nip following in the transport direction and having at least one length of hose section away from the first nip are driven at a higher speed than the rollers of the first nip. If the rollers of the further nip detect the leading end of the tube 9, this tears along the weakening line or perforation 2. After singling, the leading end of the tube section, which consists of at least one lower surface extension 5, is folded over and on the upper one Wall, which includes the surfaces 6a and 6b, fixed.

Die Falzkanten 3 bilden nun die Längsseiten des Beutels 11. Die Projektion des Perforationsabschnitts 2a der Fläche 5 und der Perforationsabschnitt 2b begrenzen nun die Lasche 10, auf dessen Innenseite die Klebemittelfläche 7 nun angeordnet ist.The folding edges 3 now form the longitudinal sides of the bag 11. The projection of the perforation section 2a of the surface 5 and the perforation section 2b now delimit the tab 10, on the inside of which the adhesive surface 7 is now arranged.

Die Figur 4 zeigt den gleichen Beutel wie die Figur 3, lediglich um die Längsachse gewendet, so dass die Unterseite sichtbar ist.The FIG. 4 shows the same bag as the FIG. 3 , only turned around the longitudinal axis, so that the underside is visible.

Die Figur 5 zeigt schematisch eine erfindungsgemäße Beutelmaschine 20. Das bahnförmige Papiermaterial 21 befindet sich auf einer Rolle gewickelt in der Abwickelstation 22 und wird von dort über Umlenkwalzen 23 in die nicht näher dargestellte Perforationsstation 24 geführt.The FIG. 5 schematically shows a bagging machine 20 according to the invention. The sheet-like paper material 21 is wound on a roll in the unwinding station 22 and is guided from there via deflection rollers 23 into the perforation station 24, not shown.

Von dort gelangt das bahnförmige Material auf eine Gegenwalze 25. Diese Walze dient als Gegenlage für die Etikettierstation 26. In dieser Station befindet sich eine Rolle 27 mit einem Band, auf welches einzelne Etiketten aufgebracht sind, die beidseitig klebend sind. Dieses Band wird taktweise von der Rolle 27 abgerollt. In jedem Takt wird ein einzelnes Etikett zu einem vorausberechneten Zeitpunkt auf das bahnförmige Papiermaterial 1 aufgebracht. Zum Andrücken des Etiketts dient hierbei das Andrückelement 29, welches in der dargestellten Ausführungsform walzenartig ausgebildet ist. Das Band, welches nun keine Etiketten mehr trägt, wird anschließend auf der Rolle 28 aufgewickelt und kann von dort entsorgt werden. Das wie beschrieben mit Etiketten versehene bahnförmige Papiermaterial gelangt anschließend in die nicht näher gezeigte Schlauchbildungsstation 30 und danach in weitere Stationen zu Herstellung der Beutel. Die Rollen und Walzen der Etikettierstation 26 sind vorzugsweise unabhängig von der übrigen Maschine antreibbar. Der Antrieb wird allerdings vorzugsweise von der Steuerung der Beutelmaschine gesteuert. Ein separater Geber für den Antrieb ist jedoch auch denkbar.From there, the web-shaped material passes onto a counter-roller 25. This roller serves as a counter-position for the labeling station 26. In this station there is a roller 27 with a band, on which individual labels are applied, which are adhesive on both sides. This tape is unrolled cyclically from the roll 27. In each cycle, a single label is applied to the sheet-like paper material 1 at a predicted time. For pressing the label in this case serves the pressing member 29, which is formed like a roll in the illustrated embodiment. The tape, which now carries no more labels, is then wound up on the roll 28 and can be disposed of there. The sheet-like paper material provided with labels as described then passes into the hose forming station 30 (not shown in detail) and then into further stations for the production of the bags. The rollers and rollers of the labeling station 26 are preferably drivable independently of the rest of the machine. However, the drive is preferably controlled by the control of the bag machine. However, a separate encoder for the drive is also conceivable.

Die Etikettierstation kann als optionaler Aufsatz vorgesehen sein, der sich auf die Seitenwände des Maschinengestells der Beutelmaschine aufsetzen lässt.The labeling station can be provided as an optional attachment, which can be placed on the side walls of the machine frame of the bag machine.
