Description

Die Erfindung betrifft eine Maschine zur Herstellung von Beuteln gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a machine for the production of bags according to the preamble of claim 1.

Beutelmaschinen sind bekannt. Sie werden beispielsweise in Schriften DE 42 05 062 A1 , DE 197 02 144 A1 und F 2 548 161 gezeigt. Zur Herstellung der gewünschten Beutel müssen an solchen Maschinen eine Vielzahl von Fertigungsparametern eingestellt werden. Zu solchen Fertigungsparametern zählen nicht nur die Maße des Beutels, sondern auch beispielsweise die Größe und die Dicke der Klebstoffaufträge, die zur Verklebung einzelner Beutelbestandteile wichtig sind. Darüber hinaus müssen zahlreiche weitere Parameter an der Maschine eingestellt werden.Pouch machines are known. They are for example in fonts DE 42 05 062 A1 . DE 197 02 144 A1 and F 2 548 161 shown. In order to produce the desired bags, a large number of production parameters have to be set on such machines. Such manufacturing parameters include not only the dimensions of the bag, but also, for example, the size and thickness of the adhesive jobs that are important for bonding individual bag components. In addition, numerous other parameters must be set on the machine.

An bekannten Maschinen steht zu diesem Zweck in der Regel ein Bedienpult zur Verfügung, an welchem derartige Fertigungsparameter eingestellt werden.On known machines, a control panel is generally available for this purpose, on which such production parameters are set.

Aus der DE 37 07 866 A1 ist eine Maschine bekannt, bei der Fertigungsparameter mit Hilfe eines taktilen Bildschirms eingestellt werden können.From the DE 37 07 866 A1 is a machine known in which manufacturing parameters can be adjusted using a tactile screen.

Die Eingabe der Fertigungsparameter und die damit verbundene Einstellung der Maschine, die zu den gewünschten Beuteln führen sollen, ist an sich relativ einfach. Jedoch müssen die Auswirkungen der Einstellung zunächst am fertigen Beutel beurteilt werden. Entspricht der fertige Beutel nicht den Anforderungen, so muss die Einstellung der Maschine gegebenenfalls mehrfach angepasst werden. Daher ist die Eingabe der Fertigungsparameter der Beutel und die damit verbundene Einstellung der Maschine sehr umständlich.The input of the manufacturing parameters and the associated setting of the machine, which should lead to the desired bags, is relatively easy in itself. However, the effects of the adjustment must first be assessed on the finished bag. If the finished bag does not meet the requirements, the setting of the machine may need to be adjusted several times become. Therefore, the input of the manufacturing parameters of the bag and the associated adjustment of the machine is very cumbersome.

Die Aufgabe der vorliegenden Erfindung ist es, eine Maschine zur Herstellung von Beuteln vorzuschlagen, die sich einfacher einstellen lässt.The object of the present invention is to propose a machine for the production of bags, which can be adjusted more easily.

Die Aufgabe wird gelöst durch die Im kennzeichnenden Teil des Anspruchs 1 aufgeführten Merkmale.The object is solved by the features listed in the characterizing part of claim 1.

Demnach umfasst das Bedienpult eine Anzeigevorrichtung, mit welcher eine graphische Darstellung des Beutels vornehmbar ist. Auf diese Weise hat der für die Einstellung der Maschine zuständige Bediener alle einzustellenden Fertigungsparameter im Blick. Das Vergessen wichtiger Fertigungsparameter wird vermieden, so dass die Einstellung der Maschine insgesamt einfacher ist. Auf der Anzeigevorrichtung können zugleich die Wertebereiche der Parameter angezeigt werden, so dass Fehleinstellungen vermieden werden. Neben der einfacheren Einstellung der Maschine ist es dabei von Vorteil, dass die Einstellung der Maschine deutlich schneller erfolgen kann und dass zugleich Ausschuss in Form von nicht wunschgemäßen Beuteln vermieden wird.Accordingly, the control panel comprises a display device with which a graphical representation of the bag is vornehmbar. In this way, the operator responsible for setting the machine has all the production parameters to be set in mind. Forgetting important manufacturing parameters is avoided, making the overall machine setting easier. At the same time, the value ranges of the parameters can be displayed on the display device, so that incorrect settings are avoided. In addition to the easier setting of the machine, it is advantageous that the adjustment of the machine can be done much faster and at the same time that rejects in the form of unwanted bags is avoided.

Bei der vorliegenden Erfindung wird ein Monitor als Anzeigevorrichtung verwendet. Auf einem Monitor können der Beutel und gegebenenfalls seine Fertigungsparameter besonders umfassend und übersichtlich dargestellt werden.In the present invention, a monitor is used as the display device. On a monitor, the bag and, where appropriate, its production parameters can be displayed in a particularly comprehensive and clear manner.

Dieser Monitor ist berührungsempfindlich, ein so genannter Touchscreen, welcher Bedienfelder aufweist, durch deren Betätigung sich Fertigungsparameter einstellen lassen. Erfindungsgemäß liegt dabei ein Teil der Bedienungsfelder im Bereich der graphischen Darstellung des Beutels. Diese Bedienungsfelder können so aufgebaut sein, dass der Wert des festzulegenden Fertigungsparameters direkt eingegeben werden kann. Die Bedienungsfelder können aber auch so aufgebaut sein, dass ausgehend von einem angezeigten Wert dieser über Inkrement- beziehungsweise Dekrementtasten erhöht oder erniedrigt werden kann. Durch diese Art der Darstellung und der Bedienung kann die Anzahl der Bedienungsfelder, die nicht direkt dem Beutel zuzuordnen sind, gering gehalten werden. Somit wird die Eingabe der Fertigungsparameter und die Einstellung der Maschine sehr stark vereinfacht.This monitor is sensitive to touch, a so-called touch screen, which has control panels, by the operation of which can set production parameters. According to the invention, a part of the control panels lies in the area of the graphical representation of the bag. These control panels can be designed so that the value of the manufacturing parameter to be defined can be entered directly. However, the control panels can also be constructed so that, starting from a displayed value, this can be increased or decreased via increment or decrement keys. By this way of presentation and operation, the number of control panels that can not directly attributable to the bag are kept low. Thus, the input of the manufacturing parameters and the setting of the machine is greatly simplified.

Vorteilhaft ist es auch, wenn die Abmaße des Beutels oder seiner Bestandteile in der Anzeigevorrichtung veränderbar sind. Wird also ein Fertigungsparameter verändert, so wird unmittelbar auch die Darstellung des Beutels in der Anzeigevorrichtung verändert. Der Einfluss des veränderten Fertigungsparameters auf das Aussehen des Beutels ist sofort wahrnehmbar.It is also advantageous if the dimensions of the bag or its components in the display device can be changed. Thus, if a manufacturing parameter is changed, the representation of the bag in the display device is also changed immediately. The influence of the changed manufacturing parameter on the appearance of the bag is immediately noticeable.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass verschiedene Ausschnitte und/oder Ansichten des Beutels mit der Anzeigevorrichtung darstellbar sind. Da bei einer zweidimensionalen Darstellung des Beutels nicht alle Fertigungsparameter gleichzeitig darstellbar sind beziehungsweise die gleichzeitige Darstellung unübersichtlich wäre, kann das Bedienpersonal zunächst eine gewünschte Ansicht wählen, um zu den Bedienfeldern zu gelangen, mit welchen Fertigungsparameter einzugeben sind. Zu diesen Ansichten kann auch eine perspektivische Ansicht des Beutels zählen, die sehr hilfreich sein kann.In a further embodiment of the invention, it is provided that different cutouts and / or views of the bag can be displayed with the display device. Since in a two-dimensional representation of the bag not all manufacturing parameters are displayed simultaneously or the simultaneous display would be confusing, the operator can first select a desired view to get to the panels with which manufacturing parameters are entered. These views can also include a perspective view of the bag, which can be very helpful.

Fig. 1 zeigt eine Anzeigevorrichtung 1 einer erfindungsgemäßen Maschine zum Herstellen von Beuteln 2. Mithilfe dieser Anzeigevorrichtung 1 wird ein Beutel 2 in der Draufsicht darstellt. In dieser Darstellung sind vom Beutel 2 der Boden 3 sowie der Tragegriff 4 zu erkennen. Zusätzlich ist ein Balken 5 gezeigt, der die Druckmarke, die für die Positionierung des Druckbildes nötig ist, symbolisiert. Druckmarken werden oft schon auf Schläuche aufgedruckt. Diese Druckmarken sind in der Regel für Lesevorrichtungen wie Lichtschranken oder auch Digitalkameras besser erkenn- bzw. lesbare Marken, welche die Position des Druckbildes für diese Lesevorrichtungen leichter sichtbar machen. So kann zum Beispiel beim Aufdrucken eines gelben Druckbildes eine schwarze Druckmarke zusätzlich aufgedruckt werden, die Auslesevorrichtung erkennt dann anhand der schwarzen Marke einfacher die Lage des gesamten Druckbildes. Die Maße der soeben genannten Beutelbestandteile 3, 4, 5 lassen sich über das Bedienpult der Maschine eingeben. An dieser Stelle sei nochmals darauf hingewiesen, dass auf gleiche Weise zahlreiche weitere Fertigungsparameter durch die Anzeigevorrichtung 1 darstellbar sind. Die Anzeigevorrichtung zeigt zudem Inkrementfelder 6 und Dekrementfelder 7, über welche sich die Werte der Fertigungsparameter, welche in Anzeigefeldern 8 angezeigt werden, erhöhen respektive erniedrigen lassen. Die Werte der Fertigungsparameter können aber auch direkt über die Eingabefelder 9 eingegeben werden. Ist die Anzeigevorrichtung 1 als Touchscreen ausgeführt, kann diese gleichzeitig als Eingabegerät fungieren, so dass die jeweiligen Felder 6, 7, 9 durch Berühren des Bildschirms bedient werden können. Fig. 1 shows a display device 1 of a machine according to the invention for producing bags 2. Using this display device 1, a bag 2 is shown in plan view. In this illustration, the bottom 2 and the carrying handle 4 can be seen from the bag 2. In addition, a bar 5 is shown, which is the Print mark, which is necessary for the positioning of the print image, symbolizes. Print marks are often already printed on hoses. These print marks are usually better readable or readable brands for reading devices such as photoelectric or digital cameras, which make the position of the printed image for these reading devices easier to see. Thus, for example, when printing a yellow print image, a black print mark can be additionally printed, the read-out device then recognizes the position of the entire print image more easily on the basis of the black mark. The dimensions of the just mentioned bag components 3, 4, 5 can be entered via the control panel of the machine. At this point, it should again be noted that in the same way numerous other manufacturing parameters can be represented by the display device 1. The display device also shows increment fields 6 and decrement fields 7, via which the values of the production parameters which are displayed in display fields 8 can be increased or decreased. The values of the production parameters can also be entered directly via the input fields 9. If the display device 1 is designed as a touchscreen, it can simultaneously act as an input device, so that the respective fields 6, 7, 9 can be operated by touching the screen.

Durch Betätigen des dem Balken 5 zugeordneten Inkrementfeldes 6 kann also die Position des Druckbildes verschoben werden. Eine Veränderung des Wertes des Parameters wird durch eine Verschiebung des Balkens 5 dargestellt.By pressing the bar 5 associated increment field 6 so the position of the printed image can be moved. A change in the value of the parameter is represented by a shift of the bar 5.

Auf gleiche Weise kann mit den Fertigungsparametern aller anderen dargestellten Beutelbestandteile verfahren werden.In the same way can be moved with the manufacturing parameters of all other bag components shown.

Insgesamt wird der Beutel 2 in Abhängigkeit von den eingestellten Werten der Fertigungsparameter in der Anzeigevorrichtung 1 dargestellt. Mit der Aktualisierung der Einstellung werden durch Steuer- und Recheneinheiten die entsprechenden Maschinenteile auf die gewählten Werte eingestellt, was beispielsweise elektromotorisch erfolgen kann. Der aktuell eingestellte Werte kann durch Sensoren ermittelt und auf den Anzeigefeldern 8 der Anzeigevorrichtung 1 angezeigt werden.Overall, the bag 2 is represented as a function of the set values of the production parameters in the display device 1. By updating the setting, the corresponding machine parts are set to the selected values by means of control and computing units, which can be done, for example, by an electric motor. The currently set values can be detected by sensors and displayed on the display panels 8 of the display device 1.

Die Anzeigevorrichtung zeigt zusätzlich noch weitere Anzeige- und Eingabefelder 10, welchen weitere Funktionen zugeordnet sein können. Zu diesen Funktion können beispielsweise die Wahl anderer Ansichten des Beutels 2 gehören. Diese Funktion können aber auch Fertigungsparametern zugeordnet sein, die sich nicht der graphischen Darstellung des Beutels 2 zuordnen lassen. Dieses können beispielsweise Betriebsparameter der Maschine sein.The display device additionally shows further display and input fields 10, to which further functions can be assigned. This function may include, for example, the choice of other views of the bag 2. However, this function can also be assigned to production parameters which can not be assigned to the graphical representation of the bag 2. This can be, for example, operating parameters of the machine.

Die Fig. 2 zeigt eine Anzeigevorrichtung 1 mit gleichem Aufbau und gleichen Funktionen wie in Fig. 1. Jedoch ist in der Anzeigevorrichtung 1 eine Ansicht des Bodens 3 des herzustellenden Beutels 2 dargestellt.The Fig. 2 shows a display device 1 with the same structure and the same functions as in Fig. 1 , However, in the display device 1, a view of the bottom 3 of the bag 2 to be produced is shown.

In der Fig. 3 ist eine Anzeigevorrichtung 1 dargestellt, welche eine Auswahl zeigt, über welche die Ansicht des Beutels 2 mit verschiedenen darzustellenden Fertigungsparametern auswählbar ist. Jede der möglichen Beutelansichten zeigt den Beutel 2 in der Draufsicht, jedoch zeigen diese verschiedene, zu beleimende Flächen, was durch die Darstellung eines entsprechenden Symbols 11 verdeutlicht wird. Durch die Anwahl einer der gezeigten Ansichten sind die entsprechenden Fertigungsparameter zugänglich. Dazu wird nach Anwahl eine Darstellung des Beutels 2 gemäß Figur 1 auf der Anzeigevorrichtung 1 erzeugt.In the Fig. 3 a display device 1 is shown, which shows a selection over which the view of the bag 2 can be selected with different production parameters to be displayed. Each of the possible bag views shows the bag 2 in plan view, but these show different areas to be glued, which is illustrated by the representation of a corresponding symbol 11. By selecting one of the views shown, the corresponding manufacturing parameters are accessible. For this purpose, after selection of a representation of the bag 2 according to FIG. 1 generated on the display device 1.

Mit der beschriebenen Erfindung wird ein übersichtliches Bedienpult geschaffen, mit welchem die Eingabe der Fertigungsparameter und damit die Einstellung der Maschine stark vereinfacht wird. Zugleich wird durch die sofortige Anzeige des Beutels 2 gemäß der eingestellten Fertigungsparameter die Herstellung von Probebeuteln überflüssig, was Zeitaufwand und Ausschuss vermeidet.With the invention described a clear control panel is created with which the input of the manufacturing parameters and thus the setting of the machine is greatly simplified. At the same time, the immediate display of the bag 2 in accordance with the set production parameters makes the production of sample bags superfluous, which avoids time and waste.

Figur 4 zeigt eine skizzierte Seitenansicht einer Beutelmaschine 135. Diese Figur wurde eingefügt, um den technischen Hintergrund erfindungsgemäßer Vorrichtungen beispielhaft zu erläutern. Hierbei geht es in ersten Linie um die Beschreibung der Kernfunktion einer solchen Beutelmaschine, die im Bereich der Schlauchabschnittbildung und Bodenmachung besteht. Hierzu wird an dieser Stelle noch einmal angemerkt, dass der Bodenmacherzylinder und der Bodenöffner auch in den deutschen Auslegeschriften 1611699 sowie 1080846 erklärt sind. Der in Figur 4 gezeigten Beutelmaschine wird eine Papierbahn 100 von rechts nach links in der Transportrichtung der Papierbahn beziehungsweise der Beutelbestandteile z zugeführt. In der Schlauchbildungsstation 101, welche die Walzen 102 umfasst, die auch das Transportband 103 führen, wird die Papierbahn zu einem Schlauch 130 zusammengelegt. Dieser Vorgang wird auch durch die Striche 104 symbolisiert, welche die Ränder der Papierbahn bei ihrem Zusammenlegen darstellen. Der fertige Papierschlauch 130 wird dem Abreißwerk 131 zugeführt. Zu diesem Abreißwerk gehören zunächst die Vorzugswalzen 106, welche die Papierbahn führen und die Papierbahnen zwischen gegeneinander in Opposition stehenden Vorzugswalzen arretieren. Nach dem Durchlaufen der Walzenspalte zwischen den Vorzugswalzen wird der Papierschlauch von dem Messer 108, welches an dem rotierenden Messerträger 107 arretiert ist, welcher das Messer entlang der gestrichelten Bahn 107a führt, perforiert. Beim Perforationsvorgang selbst bildet der Gegendruckzylinder 109 eine Gegenlage. An dem Messerträger 107 sind zwei Messer 108 angebracht, so dass bei einer Umdrehung des Messerträgers 107 zwei Querschnitte auf der Schlauchbahn 130 entstehen. Der Gegendruckzylinder 109 vollführt während dieser Zeit zwei Umdrehungen. Der vorperforierte Schlauch kommt sodann in den Walzenspalt zwischen den beiden Abreißzylindern 110, welche schneller laufen als die Vorzugswalzen 106. Dadurch wird der Schlauch an der Perforationsstelle abgerissen, was zwischen dem Messer 108 und dem Walzenspalt zwischen den Abreißzylindern 110 erfolgt. Es bleibt anzumerken, dass der Papierschlauch jetzt zu Papierschlauchabschnitten 112 vereinzelt ist. Diese Papierschlauchabschnitte 112 werden zunächst von den Transportwalzen 111 weiter transportiert. Sie erreichen die Längseinschnittstation 105, bei der zwischen den beiden Walzen 116 ein Längsschnitt in das vordere Ende des Schlauchabschnitts eingebracht wird, was zur anschließenden Bodenbildung notwendig ist. Nach der Längseinschnittstation 105 werden die Schlauchabschnitte der Bodenöffnungsstation 114, welche hauptsächlich aus dem Bodenöffner 113 besteht, zugeführt. Hier werden die Böden geöffnet. Wie bereits erwähnt zeigt die vorgenannte deutsche Auslegeschrift 1611609 einen solchen Bodenöffner. Schließlich werden die Schlauchstücke dem Bodenmacherzylinder 115 zugeführt, der diese übernimmt und an verschiedenen Bearbeitungsstationen, welche um den Bodenmacherzylinder angeordnet sind, vorbeiführt. Die erste dieser Stationen ist die Bodenfaltungs- und -Beleimungsstation 117. Die einzelnen Elemente dieser Station sind nur skizziert dargestellt und können den zitierten Druckschriften entnommen werden. In jedem Fall sind sie dem Fachmann bekannt. Nach Durchlaufen der Bodenfaltung- und-beleimungsstation werden die Böden in der Bodenschließungsstation fixiert beziehungsweise angepresst. Dieses geschieht hauptsächlich dadurch, dass die Schlauchabschnitte beziehungsweise Beutel zwischen dem Bodenmacherzylinder 115 und einem Pressband 119, welches von den Walzen 125 geführt wird, verpresst werden. Bei der gezeigten Beutelmaschine laufen die Schlauchabschnitte beziehungsweise Beutel 112 dann um einen Umkehrzylinder 120, welcher dafür sorgt, dass sich die Beutel beziehungsweise Schlauchabschnitte weiter von rechts nach links in der Transportrichtung der Beutelbestandteile z bewegen. In der Regel werden die mit fertig gelegten und fixierten Böden versehenen Schlauchabschnitte dann weiteren Bearbeitungsstationen zugeführt. So werden die Beutel oft bedruckt und/oder mit Tragegriffen versehen. An dieser Stelle wird jedoch auf die Darstellung solcher Arbeitsstationen verzichtet. Es wurde ebenfalls darauf verzichtet, die Abwicklungen für die Papierbahn 100, welche der Schlauchbildungsstation 101 vorgelagert sind, zu zeigen. FIG. 4 shows a sketched side view of a bag machine 135. This figure has been added to illustrate the technical background of inventive devices by way of example. This is in the first line to the description of the core function of such a bag machine, in the field the tube section formation and grounding exists. For this purpose, it is again noted at this point that the Bodenmacherzylinder and the Bodenöffner are also explained in the German Auslegeschriften 1611699 and 1080846. The in FIG. 4 The bag machine shown is fed to a paper web 100 from right to left in the transport direction of the paper web or the bag components z. In the hose forming station 101, which comprises the rollers 102, which also guide the conveyor belt 103, the paper web is folded into a tube 130. This process is also symbolized by the lines 104, which represent the edges of the paper web in its collapsing. The finished paper tube 130 is fed to the tear-off unit 131. To this Abreißwerk initially include the feed rollers 106 which guide the paper web and lock the paper webs between opposing opposing rollers. After passing through the nip between the feed rolls, the paper tube is perforated by the knife 108, which is locked to the rotating knife carrier 107, which guides the knife along the dashed line 107a. During the perforation process itself, the counter-pressure cylinder 109 forms an abutment. Two knives 108 are attached to the knife carrier 107, so that two cross-sections are formed on the tube web 130 during one revolution of the knife carrier 107. The impression cylinder 109 performs during this time two revolutions. The pre-perforated tube then enters the nip between the two tear-off cylinders 110, which run faster than the feed rollers 106. As a result, the tube is torn at the perforation, which takes place between the knife 108 and the nip between the Abreißzylindern 110. It should be noted that the paper tube is now singulated into paper tube sections 112. These paper tube sections 112 are first transported further by the transport rollers 111. They reach the longitudinal cutting station 105, in which a longitudinal section is introduced into the front end of the hose section between the two rollers 116, which is necessary for the subsequent bottoming. After the longitudinal incision station 105, the tube sections are supplied to the bottom opening station 114, which mainly consists of the bottom opener 113. This is where the floors are opened. As already mentioned shows the aforementioned German Auslegeschrift 1611609 such a bottom opener. Finally, the pieces of hose are fed to the bottom maker cylinder 115, which takes over these and at different processing stations, which are arranged around the Bodenmacherzylinder passes. The first of these stations is the bottom folding and gluing station 117. The individual elements of this station are shown only in outline and can be found in the cited references. In any case, they are known to the person skilled in the art. After passing through the bottom folding and gluing station, the floors are fixed or pressed in the floor closing station. This is done mainly by the tube sections or bags between the bottom maker cylinder 115 and a press belt 119, which is guided by the rollers 125, are pressed. In the bagging machine shown, the tube sections or bags 112 then run around a reversing cylinder 120, which ensures that the bags or tube sections move further from right to left in the direction of transport of the bag components z. In general, provided with finished and fixed floors hose sections are then supplied to other processing stations. Thus, the bags are often printed and / or provided with carrying handles. At this point, however, the representation of such workstations is omitted. It has also been omitted to show the developments for the paper web 100, which are upstream of the hose forming station 101.

Figur 5 zeigt jedoch noch einmal einen Beutel, wie er in einer solchen Beutelmaschine 135 hergestellt werden kann. Dieser Beutel 123 besitzt Seitenfalten 122. FIG. 5 however, again shows a bag as it can be made in such a bag machine 135. This bag 123 has gussets 122.

Die Figur 6 zeigt einen etwas fortgeschritteneren Beutel 121 mit Tragegriffen 124, welche zusätzlich mit einem Deckblatt 125 an dem Beutel fixiert worden sind. Auch Tragegriffe und die Verfahren und Vorrichtung zu deren Herstellung und der Anbringung am Beutel sind dem Fachmann bekannt und werden beispielsweise in der DE 42 05 062 A1 , welche eingangs schon erwähnt wurde, gezeigt. In der Regel bilden solche Tragegriffstationen Bestandteile der Beutelmaschine, welche dem Bodenmacherzylinder vorgelagert sind. Figur 6 verdeutlicht auch noch einmal die Gestaltung des Beutels. So ist die Breite und Höhe des Beutels noch einmal dargestellt. Die Höhe des Beutels wird durch die Schlauchabschnittlänge, welche von der Abreißstation definiert wird, bestimmt. Bei der gezeigten Beutelmaschine wird die Höhe des Beutels beziehungsweise die Schlauchabschnittslänge in erster Linie durch den Durchmesser des Umfangkreises des Messerträgers 107 bestimmt. Die Breite ergibt sich aus der Breite der Papierbahn und den Einstellungen der Schlauchlegestation 101. Auch bei Breitenwechseln müssen umfangreiche Änderungen der Einstellungen der Werkzeuge, beispielsweise am Bodenmacherzylinder, vorgenommen werden.

Carrying handles and the methods and apparatus for their preparation and attachment to the bag are known in the art and are used for example in the DE 42 05 062 A1 , which was already mentioned at the beginning, shown. As a rule, such carrying handle stations form part of the Bag machine, which are upstream of the Bodenmacherzylinder. FIG. 6 clarifies once again the design of the bag. So the width and height of the bag is shown again. The height of the bag is determined by the length of tube section defined by the tear-off station. In the case of the bagging machine shown, the height of the bag or the tube section length is determined primarily by the diameter of the circumferential circle of the knife carrier 107. The width results from the width of the paper web and the settings of the hose station 101. Even with width changes extensive changes in the settings of the tools, for example, on the floor maker cylinder must be made.
