Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von Beuteln oder Säcken aus mindestens zwei Lagen aus Kunststoff oder Papier und einen Beutel oder Sack.The invention relates to a device for producing bags or sacks of at least two layers of plastic or paper and a bag or sack.

Nach dem heute bekannten Stand der Technik werden die Beutel oder Säcke nach dem Verschweißen in einer Schweißeinrichtung in Paketen durch Klemmen oder Aufnadelung gesammelt.According to the prior art known today, the bags or sacks are collected after welding in a welding device in packages by clamping or pinning.

Bekannt ist aus der DE 41 02 877 A1 eine Vorrichtung zum Herstellen und Stapeln von Beuteln. Die Vorrichtung enthält eine Schweißeinrichtung die aus einem oberen auf- und abbewegbaren Schweißbalken besteht, an dem ein Trennmesser befestigt ist. Zusätzlich enthält die Schweißeinrichtung einen zugehörigen unteren Schweißbalken, der unbeweglich im Maschinengestell gehalten wird. Der untere Schweißbalken weist eine querverlaufende Nut auf, in die ein an dem oberen Schweißbalken befestigtes Messer eintauchen kann, so dass von einer Schlauchbahn bei dem jeweiligen Absenken des oberen Schweißbalkens ein Bodennahtbeutel abgetrennt wird. Die Bodennaht wird jeweils durch die Schweißeinrichtung gebildet. In dem Moment, in dem das Messer in die Nut eintaucht, wird ein Schieber nach unten bewegt, der den Beutel auf eine Reihe von Nadeln aufnadelt.Is known from the DE 41 02 877 A1 a device for producing and stacking bags. The device comprises a welding device which consists of an upper movable up and down welding bar on which a cutting knife is attached. In addition, the welder includes an associated lower welding bar that is immovably held in the machine frame. The lower welding bar has a transverse groove into which a knife attached to the upper welding bar can dip, so that a bottom seam bag is separated from a tube web at the respective lowering of the upper welding bar. The bottom seam is formed in each case by the welding device. The moment the knife dips into the groove, a pusher is moved down, pincing the bag onto a series of needles.

Nachteilig ist nach dem heute bekannten Stand der Technik, dass der Trennschnitt zwischen herzustellenden Beuteln oder Säcken nur mittels eines umlaufenden Messers möglich ist. Alternativ kann der Trennschnitt nur mit Hilfe eines Zackenschnittmessers in Verbindung mit Nadeleinstichen erzeugt werden.The disadvantage of the prior art known today is that the separating cut between bags or sacks to be produced is possible only by means of a rotating knife. Alternatively, the severance cut can only be created by means of a serrated knife in conjunction with needle punctures.

Aufgabe der Erfindung ist es daher, bei der Herstellung von Beuteln oder Säcken aus Kunststoff oder Papier eine glatte Füllkante ohne Nadeleinstiche zu erzeugen. Des Weiteren soll ein kurzer Abstand zwischen Schnittkante und Schweißnaht erzeugt werden.The object of the invention is therefore to produce a smooth filling edge without needle puncture in the manufacture of bags or bags made of plastic or paper. Furthermore, a short distance between cutting edge and weld should be generated.

Die Aufgabe der Erfindung wird dadurch gelöst, dass die Vorrichtung ein oberes heb- und senkbares beheizbares Heizelement zur Herstellung einer Schweißnaht zwischen den Lagen aufweist, dass ein heb- und senkbares Schneidmesser in Vorschubrichtung hinter dem oberen heb- und senkbaren beheizbaren Heizelement angeordnet ist und dass eine auslaufseitige Schneidkante einer Auflageplatte als gegenwirkende Schneidkante für das klingenförmige Schneidmesser gestaltet ist, wobei das obere heb- und senkbare beheizbare Heizelement gegen die Auflageplatte bewegbar angeordnet ist und die Auflageplatte die Lagen abstützt.The object of the invention is achieved in that the device has an upper raisable and lowerable heatable heating element for producing a weld between the layers, that a liftable and lowerable cutting blade is arranged in the feed direction behind the upper raised and lowered heatable heating element and that an outlet-side cutting edge of a support plate is designed as a counter-cutting edge for the blade-shaped cutting blade, wherein the upper raisable and lowerable heated heating element is arranged movable against the support plate and the support plate supports the layers.

Mittels der Vorrichtung gemäß der Erfindung sind Beutel oder Säcke herstellbar, die eine leicht zu öffnende Einfüllseite bei gleichbleibender Nahtqualität und gleichbleibendem Nahtüberstand aufweisen. Auch sind mittels der Vorrichtung gleichwertige Produkte herstellbar, die eine hohe Wiederholgenauigkeit haben. Weiterhin ist eine hohe Produktionsgeschwindigkeit möglich. Des Weiteren lassen sich Beutel oder Säcke herstellen, bei denen Folien mit unterschiedlicher Dicke verwendet werden, die anschließend mit einer Schweißnaht verschweißt werden. Auch ist die Bauweise der bevorzugten Vorrichtung nach der Erfindung einfach und preiswert.By means of the device according to the invention bags or sacks can be produced, which have an easy-to-open filling side with constant seam quality and consistent seam overhang. Also, by means of the device equivalent products can be produced, which have a high repeatability. Furthermore, a high production speed is possible. In addition, bags or sacks can be made using films of different thickness, which are then welded together with a weld. Also, the construction of the preferred device according to the invention is simple and inexpensive.

Eine vorteilhafte Ausgestaltung ist, dass die Auflageplatte ein beheizbares Heizelement enthält.An advantageous embodiment is that the support plate includes a heatable heating element.

Eine weitere vorteilhafte Ausgestaltung ist, dass das obere heb- und senkbare beheizbare Heizelement oberhalb der Auflageplatte, insbesondere oberhalb des beheizbaren Heizelementes der Auflageplatte, angeordnet ist.A further advantageous embodiment is that the upper raisable and lowerable heatable heating element above the support plate, in particular above the heated heating element of the support plate, is arranged.

Eine weitere vorteilhafte Ausgestaltung ist, dass das beheizbare Heizelement der Auflageplatte ein Glühband ist. Die Verwendung eines Glühbandes ist vorteilhaft, da die Erwärmung und Kühlung sehr schnell durchführbar ist.A further advantageous embodiment is that the heatable heating element of the support plate is an annealing strip. The use of an annealing strip is advantageous because the heating and cooling can be carried out very quickly.

Eine weitere vorteilhafte Ausgestaltung ist, dass das obere heb- und senkbare beheizbare Heizelement ein Querschweißbalken ist.A further advantageous embodiment is that the upper raisable and lowerable heated heating element is a transverse welding bar.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Auflageplatte des Weiteren eine Isolierung, vorzugsweise eine thermische und elektrische Isolierung, und eine Gummilage, vorzugsweise eine Gummilage aus Silikon, enthält. Die Isolierung hat den Vorteil, dass das Heizelement der Auflageplatte gegenüber der Auflageplatte thermisch und elektrisch isoliert ist. Auch ist das Heizelement der Auflageplatte mittels der Isolierung schnell erwärmbar, da mittels der Isolierung die Wärmeübertragung in die Auflageplatte reduziert wird. Die Verwendung einer Gummilage hat den Vorteil, dass die Gummilage in der Auflageplatte bei der Herstellung einer Schweißnaht dämpfend wirkt. Zusätzlich ist das Heizelement in der Auflageplatte mittels der Gummilage beweglich angeordnet.A further advantageous embodiment is that the support plate further includes insulation, preferably a thermal and electrical insulation, and a rubber layer, preferably a rubber layer of silicone. The insulation has the advantage that the heating element of the support plate is thermally and electrically insulated from the support plate. Also, the heating element of the support plate can be heated quickly by means of the insulation, since by means of the insulation, the heat transfer is reduced in the support plate. The use of a rubber layer has the advantage that the rubber layer in the support plate in the production of a weld has a damping effect. In addition, the heating element is movably arranged in the support plate by means of the rubber layer.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Auflageplatte mittels einer Kühleinheit kühlbar ist. Dadurch ist es möglich, dass nur der Bereich um das beheizbare Heizelement in der Auflageplatte beheizbar ist und dass der Schneidbereich an der auslaufseitigen Schneidkante mit Hilfe der Kühleinheit kühlbar ist.A further advantageous embodiment is that the support plate can be cooled by means of a cooling unit. This makes it possible that only the area around the heatable heating element in the support plate can be heated and that the cutting area can be cooled at the outlet-side cutting edge with the aid of the cooling unit.

Eine weitere vorteilhafte Ausgestaltung ist, dass im Bereich zwischen dem Schneidmesser und dem oberen heb- und senkbaren beheizbaren Heizelement eine thermische Isolierung angeordnet ist. Mit Hilfe der thermischen Isolierung wird die Wärmeübertragung des oberen heb- und senkbaren beheizbaren Heizelements in den Schneidbereich des Schneidmessers abgeschirmt.A further advantageous embodiment is that in the area between the cutting blade and the upper raisable and lowerable heatable heating element, a thermal insulation is arranged. With the help of thermal insulation, the heat transfer of the upper raisable and lowerable heatable heating element is shielded in the cutting area of the cutting blade.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Vorrichtung einlaufseitig vor dem oberen heb- und senkbaren beheizbaren Heizelement eine thermische Isolierung enthält. Mit Hilfe der thermischen Isolierung ist es möglich, dass die zugeführten Lagen nicht durch die Wärmeübertragung des oberen heb- und senkbaren beheizbaren Heizelementes beeinflusst werden.A further advantageous embodiment is that the device contains a thermal insulation upstream of the upper raised and lowered heatable heating element. With the help of thermal insulation, it is possible that the layers supplied are not affected by the heat transfer of the upper raisable and lowerable heatable heating element.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Auflageplatte um 180° drehbar ist. Dadurch ist es möglich, sowohl die eine Seite als auch nach der Drehung um 180° die andere Seite der Auflageplatte zu verwenden. Die Auflageplatte weist dabei zwei Schneidkanten auf, die jeweils als gegenwirkende Schneidkante für das klingenförmige Schneidmesser verwendbar sind.A further advantageous embodiment is that the support plate is rotatable by 180 °. This makes it possible to use both the one side and after rotation by 180 ° the other side of the support plate. The support plate has two cutting edges, which can be used as counteracting cutting edge for the blade-shaped cutting blade.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Auflageplatte heb- und senkbar ist. Dadurch ist es möglich, dass die Auflageplatte alternativ oder ergänzend zu der Bewegung des oberen heb- und senkbaren beheizbaren Heizelementes und der Bewegung des heb- und senkbaren Schneidmessers in der Vorrichtung bewegbar ist. Im Bedarfsfall ist es somit möglich, dass die heb- und senkbare Auflageplatte den Schneid- und Schweißvorgang unterstützt.A further advantageous embodiment is that the support plate can be raised and lowered. This makes it possible that the support plate is movable as an alternative or in addition to the movement of the upper raisable and lowerable heatable heating element and the movement of the raisable and lowerable cutting blade in the device. If necessary, it is thus possible that the liftable and lowerable support plate supports the cutting and welding process.

Eine weitere vorteilhafte Ausgestaltung ist, dass die Vorrichtung ein abgestuftes Transportband zum Abtransport der mit einer Schweißnaht verschweißten Lagen aufweist. Die Aufgabe des abgestuften Transportbandes ist es dabei, dass die mit einer Schweißnaht verschweißten Lagen nicht vollständig übereinander liegen, so dass die jeweiligen Schweißnähte nicht mit einer Lage verkleben. Weiterhin ist es möglich, dass die jeweiligen Schweißnähte mit Hilfe der Abstufung weiter auskühlen.A further advantageous embodiment is that the device has a stepped conveyor belt for removing the welded to a weld layers. The task of the stepped conveyor belt is that the layers welded together with a weld do not lie completely over one another, so that the respective welds do not stick to one layer. Furthermore, it is possible that the respective welds continue to cool with the aid of the gradation.

Alternativ können die beiden Lagen sich auch aus einem Halbschlauch bilden, der nur an der offenen Seite des einen sich bildenden Randes, der parallel zur Vorschubrichtung 17 verläuft, mit einer Seitennaht verschweißt ist. Alternativ können die beiden Lagen sich auch aus einem Vollschlauch bilden, bei dem keine Seitennaht notwendig ist.In the example below 1 become the device 1 for the production of bags or sacks at least two layers in the feed direction 17 fed. The layers consist of paper or plastic. In the example below 1 and 2 be two layers of plastic in the feed direction 17 the device 1 with the help of the preferred roller pair 8th fed. In the example, the two layers of plastic are each individual layers, at the two edges, which are parallel to the feed direction 17 run, each welded to a side seam. Alternatively, the two layers can also form a half-tube, which only at the open side of a forming edge, which is parallel to the feed direction 17 runs, is welded with a side seam. Alternatively, the two layers can also form a full hose, in which no side seam is necessary.

Der Querschweißbalken 2 wird mittels der Heizeinrichtung 9 kontinuierlich auf eine Temperatur oberhalb der Schmelztemperatur der beiden Lagen beheizt. Im Ausführungsbeispiel ist der Querschweißbalken 2 auf eine Temperatur von etwa 250°C, die oberhalb der Schmelztemperatur der beiden Lagen ist, beheizt.The transverse welding bar 2 is by means of the heater 9 continuously heated to a temperature above the melting temperature of the two layers. In the embodiment, the transverse welding bar 2 heated to a temperature of about 250 ° C, which is above the melting temperature of the two layers.

Das Glühband 12 wird von einer erhöhten Grundtemperatur getaktet auf eine Temperatur oberhalb der Schmelztemperatur der beiden Lagen aufgeheizt. Im Ausführungsbeispiel wird das Glühband 12 von der erhöhten Grundtemperatur getaktet auf eine Temperatur von etwa 250°C aufgeheizt. Das Gühband 12 wird nur dann von der erhöhten Grundtemperatur weiter beheizt, wenn ein Schweißvorgang erfolgt. Bei keiner Schweißung wird das Glühband 12 nicht beheizt und kühlt sich somit aufgrund seiner geringen Wärmekapazität wieder auf die erhöhte Grundtemperatur ab. Alternativ kann das Glühband 12 auch auf eine Temperatur oberhalb der Schmelztemperatur der beiden Lagen dauerbeheizt sein, so dass sich das Glühband 12 bei keiner Schweißung nicht abkühlt. Ein dauerbeheiztes Glühband 12 wird im Ausführungsbeispiel nicht verwendet.The glow band 12 is clocked from an elevated base temperature heated to a temperature above the melting temperature of the two layers. In the embodiment, the glow band 12 timed from the elevated base temperature to a temperature of about 250 ° C heated. The belt 12 is only further heated by the increased base temperature when a welding operation takes place. No welding will make the glow band 12 not heated and thus cools due to its low heat capacity back to the increased base temperature. Alternatively, the glow band 12 also be permanently heated to a temperature above the melting temperature of the two layers, so that the glow band 12 not cool at any weld. A permanently heated glow band 12 is not used in the embodiment.

Das Vorzugswalzenpaar 8 ist in Vorschubrichtung 17 vor dem Querschweißbalken 2 und der Auflageplatte 3 nach 2 angeordnet. Die Wärmeübertragung des Querschweißbalkens 2 in die beiden Lagen wird mit Hilfe des einlaufseitigen Kühlblechs 7b reduziert.The preferred roller pair 8th is in the feed direction 17 in front of the transverse welding bar 2 and the platen 3 to 2 arranged. The heat transfer of the transverse welding bar 2 in the two layers is using the inlet side cooling plate 7b reduced.

Die in Vorschubrichtung 17 zugeführten zwei Lagen aus Kunststoff werden dabei diskontinuierlich zwischen dem Querschweißbalken 2 und der Auflageplatte 3 beziehungsweise zwischen dem Schneidmesser 4 und der Schneidkante 10 hindurch geführt.The in feed direction 17 supplied two layers of plastic are doing discontinuously between the transverse welding bar 2 and the platen 3 or between the cutting blade 4 and the cutting edge 10 passed through.

Im Folgenden wird die Herstellung eines Beutels oder Sacks in der Vorrichtung 1 beispielhaft beschrieben.The following is the preparation of a bag or bag in the device 1 described by way of example.

Dazu befinden sich die beiden Lagen in einer Ruhelage zwischen dem Schneidmesser 4 und der Schneidkante 10 beziehungsweise zwischen dem Querschweißbalken 2 und der Auflageplatte 3.For this purpose, the two layers are in a rest position between the cutting blade 4 and the cutting edge 10 or between the transverse welding bar 2 and the platen 3 ,

In der Ruhelage werden die beiden Lagen mit Hilfe des klingenförmigen Schneidmessers 4 und der Schneidkante 10 der Auflageplatte 3 vor dem Querschweißen durchgeschnitten, in dem sich das Schneidmesser 4 mit der Hubbewegung 16 in Richtung Schneidkante 10 absenkt. Das Schneidmesser 4 und die Schneidkante 10 erzeugen einen Trennschnitt durch die beiden Lagen nach 1 beziehungsweise 2.In the rest position, the two layers with the help of the blade-shaped cutting knife 4 and the cutting edge 10 the platen 3 cut through before transverse welding, in which the cutting blade 4 with the lifting movement 16 in the direction of the cutting edge 10 lowers. The cutting knife 4 and the cutting edge 10 create a separation cut through the two layers 1 respectively 2 ,

Beim Durchschneiden der beiden Lagen ergibt sich ein qualitativ hochwertiger Schnitt. Mit Hilfe des auslaufseitigen Kühlbleches 7a wird der Schneidbereich von Schneidmesser 4 und Schneidkante 10 gegenüber der Wärmeübertragung des Querschweißbalkens 2 abgeschirmt.When cutting through the two layers results in a high quality cut. With the help of the outlet side cooling plate 7a becomes the cutting area of cutting knife 4 and cutting edge 10 opposite the heat transfer of the transverse welding bar 2 shielded.

In der Ruhelage der beiden Lagen senkt sich auch der Querschweißbalken 2 mit der Hubbewegung 16a in Richtung Auflageplatte 3 auf die beiden Lagen ab. Die beiden Lagen werden dabei von der Auflageplatte 3 abgestützt. Der beheizte Querschweißbalken 2 schweißt zusammen mit dem im Beispiel getaktet beheizten Glühband 12 eine Schweißnaht, im Beispiel eine Querschweißnaht. Die Querschweißnaht entspricht im Beispiel einer Bodennaht. In dem Moment des Schweißens der Querschweißnaht ist das Glühband 12 auf etwa 250°C aufgeheizt. Die Querschweißnaht verläuft jeweils über die gesamte Breite der beiden Lagen und quer zur Vorschubrichtung 17.In the rest position of the two layers also lowers the transverse welding bar 2 with the lifting movement 16a in the direction of the support plate 3 on the two layers. The two layers are thereby from the support plate 3 supported. The heated transverse welding bar 2 welds together with the clocked heated in the example glow band 12 a weld, in the example a transverse weld. The transverse weld corresponds in the example of a bottom seam. At the moment of welding the transverse weld is the glow band 12 heated to about 250 ° C. The transverse weld extends over the entire width of the two layers and across the feed direction 17 ,

Mit Hilfe der Anordnung des Schneidmessers 4, der schneidenden Schneidkante 10, des Querschweißbalkens 2 und des Glühbandes 12 in der Vorrichtung 1 ergibt sich ein Nahtüberstand, der sehr kurz ist. Der Nahtüberstand ist der Abstand zwischen der Schnittkante durch die beiden Lagen und der im gleichen Takt geschweißten Querschweißnaht, die die beiden Lagen an der Stelle der Querschweißnaht miteinander verschweißt.With the help of the arrangement of the cutting knife 4 , the cutting edge cutting 10 , the crosswelding bar 2 and the glow band 12 in the device 1 results in a seam overhang, which is very short. The seam overhang is the distance between the cutting edge through the two layers and the welded at the same time transverse weld, which welded together the two layers at the location of the transverse weld.

Anschließend hebt sich das Schneidmesser 4 von der Schneidkante 10 mit der Hubbewegung 16 wieder ab. Auch der Querschweißbalken 2 hebt sich von der Auflageplatte 3 mit der Hubbewegung 16a wieder von den beiden Lagen ab. Dabei kühlt sich das Glühband 12 wieder auf die erhöhte Grundtemperatur ab, da dieses nur beim Schweißen auf etwa 250°C beheizt wird.Then the cutting knife lifts 4 from the cutting edge 10 with the lifting movement 16 again. Also the transverse welding bar 2 rises from the platen 3 with the lifting movement 16a again from the two layers. This cools the glow band 12 again on the increased base temperature, since this is heated only at welding to about 250 ° C.

Anschließend bewegen sich die beiden durchgeschnittenen und mit einer Querschweißnaht verschweißten Lagen um die gewünschte Länge des Beutels oder Sacks in Vorschubrichtung 17 zwischen Schneidmesser 4 und Schneidkante 10 hindurch und stoppen bei Erreichen der gewünschten Länge.Subsequently, the two cut and welded with a transverse weld layers move to the desired length of the bag or bag in the feed direction 17 between cutting knife 4 and cutting edge 10 through and stop when reaching the desired length.

In der Ruhelage der beiden Lagen senkt sich das Schneidmesser 4 in Richtung der Schneidkante 10 der Auflageplatte 3 mit der Hubbewegung 16 erneut ab. Die beiden im vorherigen Takt mit einer Querschweißnaht verschweißten Lagen werden mit Hilfe des Schneidmessers 4 und der Schneidkante 10 der Auflageplatte 3 durchgeschnitten.In the rest position of the two layers, the cutting blade lowers 4 in the direction of the cutting edge 10 the platen 3 with the lifting movement 16 again. The two in the previous cycle with a transverse weld welded layers are using the cutting blade 4 and the cutting edge 10 the platen 3 cut across.

Direkt nach denn Schnitt des Schneidmessers 4 mit der Schneidkante 10 durch die beiden Lagen fällt ein jeweiliger, schon im vorherigen Takt geschnittener und mit einer Querschweißnaht geschweißter Beutel oder Sack auf das Transportband 5.Immediately after cutting the cutting blade 4 with the cutting edge 10 through the two layers falls a respective, cut in the previous cycle and welded with a transverse weld bag or bag on the conveyor belt 5 ,

Der Beutel oder der Sack haben nur noch eine Öffnung, wenn diese auf das Transportband 5 fallen. Die Öffnung des Beutels oder Sacks ist jeweils bezogen auf die Länge der Beutels oder Sacks gegenüberliegend der Querschweißnaht des Beutels oder Sacks angeordnet. Die Beutel und Säcke werden mit Hilfe des Transportbandes 5 anschließend abtransportiert. Das Transportband 5 wird dabei diskontinuierlich oder kontinuierlich bewegt. Das Transportband 5 enthält nach 2 eine Bandstufe 18, mit Hilfe der die Querschweißnaht des jeweils hergestellten Beutels oder Sacks noch weiter kühlbar ist. Je nach herzustellender Länge der Beutel oder Säcke ist die Bandstufe 18 in Richtung oder gegen die Richtung der Transportrichtung 19 verschiebbar. Bevorzugt erfolgt eine Verschiebung 20 der Bandstufe 18 manuell. Die Bandstufe 18 stuft gemäß 2 das Transportband 5 ab.The bag or sack will only have one opening when placed on the conveyor belt 5 fall. The opening of the bag or bag is arranged in each case based on the length of the bag or bag opposite the transverse weld of the bag or bag. The bags and sacks are made using the conveyor belt 5 then transported away. The conveyor belt 5 is thereby moved discontinuously or continuously. The conveyor belt 5 contains after 2 a band stage 18 , with the help of the transverse weld of the bag or bag produced in each case is still coolable. Depending on the length of the bags or sacks to be produced is the band stage 18 in the direction or against the direction of the transport direction 19 displaceable. Preferably, a shift takes place 20 the band stage 18 manually. The band stage 18 according to 2 the conveyor belt 5 from.

Die Bandstufe 18 ist in dem Transportband 5 im Ausführungsbeispiel nach 2 in eine Position verschoben worden, so dass der Abstand zwischen Bandstufe 18 und Schneidmesser 4 kleiner ist als die Länge des jeweils hergestellten Beutels oder Sacks. Dadurch ist eine Auffächerung der jeweils hergestellten Beutel oder Säcke möglich.The band stage 18 is in the conveyor belt 5 in the exemplary embodiment 2 has been moved to a position so that the distance between band stage 18 and cutting knife 4 smaller than the length of each bag or bag produced. As a result, a fanning of each bag or bags produced is possible.

Nach 2 rutschen die hergestellten Beutel oder Säcke mit Hilfe des Eigengewichts von der Bandstufe 18 und mit Hilfe der Bewegung in Transportrichtung 19 nacheinander herunter und fächern dabei gemäß 2 auf, so dass sich die geschweißten Querschweißnähte nicht durch die Auffächerung berühren und die Querschweißnähte somit weiter auskühlen.To 2 slip the bags or bags produced by the weight of the tape stage 18 and with the help of the movement in the transport direction 19 down one after the other and fan out accordingly 2 so that the welded transverse weld seams do not touch each other due to the fanning out and thus further cool the transverse weld seams.

Anschließend werden die Beutel oder Säcke beispielsweise manuell zu einem Packet gepackt.Subsequently, the bags or sacks are packed, for example, manually into a packet.
