- the severing of the sealing seams can comprise a renewed heating of the sealing seams in order to heat-seal the material web layers which have been folded onto one another.
- the possibly first heating of the material web and the severing of the sealing seams take place at separate stations.
- the in Figure 1 The bag 1 shown in the unfilled state is formed from a continuous material web 24.
- the material has a paper layer 2 and a sealable coating 3 arranged over the entire surface.
- the paper layer 2 on the outside of the bag and the sealable coating 3 face an interior 4 of the bag.
- the bag has a rectangular shape with a Longitudinal dimension 7 and a transverse dimension 8, the longitudinal dimension 7 being greater than the transverse dimension 8.
- the material web 24 is folded back onto itself in the area of a folding arrangement 11 in the illustrated embodiment with an inserted head fold 22, that is, by means of three folds, so that a front bag wall 5 and a rear bag wall 6 are formed.
- the head fold is inserted between the front and rear bag walls 5, 6 by about 6 to 7 centimeters.
- the material web sections placed on top of one another have aligned side edges 13 which extend in the longitudinal dimension of the bag.

- the front and rear bag walls are not directly welded to one another, but the front bag wall 5 is welded to the head fold portion facing it and the rear bag wall 6 is welded to the head fold portion facing it.
- the bag 1 is open, so that in the direction of the transverse dimension 8 no sealing seam is provided on the bottom transverse side 9.
- a protruding material section 26 projecting beyond the bag opening 30 is provided on the rear wall of the bag 6.
- a short material web section is also folded back on this, which is fastened at the side edges 13 also by corresponding sealing seams 25 on the rear bag wall 6.
- two holes 27 are provided which are used to attach the bag to wicket pins. The purpose of the folding back is to prevent the holes 27 from being torn out when the bag 1 is pulled off the wicket pins.
- Figure 2 shows in particular the folding arrangement 11, the head fold 22 on the basis of two bags 1 lying next to one another the third fold is arranged therebetween and connects the folded-back portions to one another, so that the head region 10 has the shape of a "Y" from a side perspective.
- the sealing seam 25 follows the course of the head fold 22 and is formed on the one hand between the front bag wall 5 and the head fold portion folded back onto it and on the other hand between the rear bag wall 6 and the head fold portion folded back onto it.
- the illustrated bags 1 also each have sealing seams 25 with a predetermined width b of 1 cm.

- the handle strip 23 has an oval punched handle 29, via which the bag can be carried. If the grip strip is alternatively arranged in the head area, it can be produced before the bag is filled, that is, if the bag is still flat, by producing a flat sealing seam in the predetermined grip width Gb. If the grip strip is provided in the bottom area, it is heat-sealed over its entire surface after the bag 1 has been filled. The interior 4 of the bag 1 is also closed. At the upper end of the grip strip 23, the section having the wicket pin holes 27 is cut off. In a separate step, the handle 29 is punched out.
- Figure 7 shows the bottom area 28 in an enlarged view.
- the protruding material section 26 Adjacent to the bag opening 30, the protruding material section 26 is provided, which has a free section immediately adjacent to the opening 30, in which the sealable coating 3 of the rear wall of the bag is exposed.

Description
Die Erfindung betrifft einen Beutel zum Aufnehmen einer Mehrzahl Hygieneartikel, insbesondere Windeln, welcher aus einem Material gebildet ist, das eine Papierschicht sowie eine zumindest abschnittsweise, insbesondere vollflächig, darauf angeordnete siegelfähige Beschichtung aufweist, welche einem Innenraum des Beutels zugewandt ist, wobei der Beutel eine vordere Beutelwandung und eine rückseitige Beutelwandung aufweist, welche aus einer zusammenhängenden Materialbahn gebildet sind, und welche sich zumindest in einer Längsabmessung und in einer Querabmessung erstrecken, wobei der Beutel an den gegenüberliegenden Querseiten einen Kopfbereich sowie einen Bodenbereich aufweist, wobei die vordere Beutelwandung und die rückseitige Beutelwandung über eine im Kopfbereich vorgesehene Faltungsanordnung aufeinander gefaltet sind und im Bereich von sich in der Längsabmessung erstreckenden, jeweils in einer vorbestimmten Breite die siegelfähige Beschichtung aufweisenden Seitenrändern miteinander heißversiegelt sind.The invention relates to a bag for holding a plurality of hygiene articles, in particular diapers, which is formed from a material which has a paper layer and a sealable coating arranged thereon at least in sections, in particular over the entire area, which faces an interior of the bag, the bag having a has front bag wall and a rear bag wall, which are formed from a coherent web of material, and which extend at least in a longitudinal dimension and in a transverse dimension, the bag having a head area and a bottom area on the opposite transverse sides, the front bag wall and the rear Bag wall are folded onto one another via a folding arrangement provided in the head area and are joined together in the area of longitudinally extending side edges each having the sealable coating in a predetermined width are ice-sealed.
Aus dem Stand der Technik sind insbesondere Hygieneartikelverpackungen aus PE-Folie bekannt. Obwohl es sich dabei um eine wirtschaftlich und ökologisch hochoptimierte Verpackungsanwendung handelt, gibt es bei Verbrauchern Präferenzen für das Material Papier - aufgrund der Vermutung, dass es umweltfreundlicher wäre. Eine besondere Herausforderung dabei ist jedoch, dass eine Trennung und gleichzeitige Verschweißung der Seitenränder der Beutel bei diesem Material nicht mittels Trennschweißen wie bei PE-Beuteln erfolgen kann. Für diese Funktion werden oft Papiere mit einer zusätzlichen Folienschicht, beispielsweise aus Polyethylen PE eingesetzt. Damit kann jedoch die Rezyklierbarkeit und Kompostierbarkeit eingeschränkt sein. Vor diesem Hintergrund sind beispielsweise Beschichtungen zu bevorzugen, die folienfrei sind und einen großen Anteil an biologisch abbaubaren Inhaltsstoffen aufweisen. Ferner besteht eine weitere Herausforderung bei Papier mit siegelfähiger Beschichtung darin, Verpackungsaußenseiten, bei denen jeweils die Papierlage des Materials aufeinander zuweist, beispielsweise in Eckbereichen miteinander zu verbinden.In particular, hygiene article packaging made from PE film is known from the prior art. Although this is an economically and ecologically highly optimized packaging application, consumers have preferences for paper based on the assumption that it would be more environmentally friendly. A particular challenge, however, is that a separation and simultaneous welding of the side edges of the bags cannot be done with this material by means of separation welding as with PE bags. Papers with an additional film layer, for example made of polyethylene PE, are often used for this function. However, this can limit the recyclability and compostability. Against this background, for example, coatings are to be preferred that are film-free and have a large proportion of biodegradable ingredients. Furthermore, a further challenge with paper with a sealable coating is to connect the outer sides of the packaging, in which the paper layer of the material faces one another, for example in corner areas.
Es ist daher die Aufgabe der Erfindung, eine umweltfreundliche Hygieneartikelverpackungen derart zu verbessern, dass die Herstellung vereinfacht ist.It is therefore the object of the invention to improve environmentally friendly hygiene article packaging in such a way that production is simplified.
Diese Aufgabe wird durch einen Beutel mit den Merkmalen des Anspruchs 1 und durch das Verfahren nach Anspruch 13 gelöst. Die abhängigen Ansprüche betreffen jeweils vorteilhafte Ausführungsformen der Erfindung.This object is achieved by a bag with the features of claim 1 and by the method according to
Demgemäß ist vorgesehen, einen Beutel zum Aufnehmen einer Mehrzahl Hygieneartikel, insbesondere Windeln, bereitzustellen, welcher aus einem Material gebildet ist, das eine Papierschicht sowie eine zumindest abschnittsweise, insbesondere vollflächig, darauf angeordnete siegelfähige Beschichtung aufweist, welche einem Innenraum des Beutels zugewandt ist, wobei der Beutel eine vordere Beutelwandung und eine rückseitige Beutelwandung aufweist, welche aus einer zusammenhängenden Materialbahn gebildet sind, und welche sich zumindest in einer Längsabmessung und in einer Querabmessung erstrecken, wobei der Beutel an den gegenüberliegenden Querseiten einen Kopfbereich sowie einen Bodenbereich aufweist, wobei die vordere Beutelwandung und die rückseitige Beutelwandung über eine im Kopfbereich vorgesehene Faltungsanordnung aufeinander gefaltet sind und im Bereich von sich in der Längsabmessung erstreckenden, jeweils in einer vorbestimmten Breite die siegelfähige Beschichtung aufweisenden Seitenrändern miteinander heißversiegelt sind.Accordingly, provision is made to provide a bag for receiving a plurality of hygiene articles, in particular diapers, which is formed from a material which has a paper layer and a sealable coating arranged thereon at least in sections, in particular over the entire area, which faces an interior of the bag, with the bag has a front bag wall and a rear bag wall, which are formed from a coherent web of material and which extend at least in a longitudinal dimension and in a transverse dimension, the bag having a head area and a bottom area on the opposite transverse sides, the front bag wall and the back wall of the bag is folded onto one another via a folding arrangement provided in the head area and in the area of side rails extending in the longitudinal dimension and each having the sealable coating in a predetermined width Change are heat-sealed together.
Da das verwendete Beutelmaterial nicht mittels Trennschweißen trenn- und verbindbar ist, ist es besonders vorteilhaft, die Seitenränder des Beutels auf einer Breite von mehreren Millimetern durch Heißversiegeln miteinander zu verbinden. Durch die dem Innenraum zuweisenden Flächen der Beschichtung und das Verschweißen dieser gegenüberliegenden Siegelbeschichtungen ist es ausreichend, die Siegelbeschichtung in einer Dicke auf das Papier aufzubringen, welche der Hälfte der zum Fügen der Seitenränder notwendigen Siegelmaterialdicke entspricht. Es kann vorgesehen sein, dass der Bodenbereich zum Entnehmen der Hygieneartikel vorgesehen ist. Dazu kann der Bodenbereich eine Perforierung aufweisen. Die Perforierung kann insbesondere in der Nähe der Seitenränder parallel zur Längsabmessung des Beutels eingebracht sein. Es kann ferner vorgesehen sein, die Beutel zum Befüllen mit Hygieneartikeln als Wicketbeutel oder Stiftstapelbeutel bereitzustellen. Dazu kann der Bodenbereich eine zum Innenraum des Beutels weisende Öffnung aufweisen. Ferner kann der Bodenbereich an vorderen oder der rückseitigen Beutelwandung einen überstehenden Materialabschnitt aufweisen. Dieser kann zum Verschließen des Beutels dienen. Der überstehende Materialabschnitt kann ferner zwei Wicket-Pin-Löcher aufweisen. Um ein Abreißen des Materials beim Abziehen vom Wicket-Pin zu vermeiden, kann vorgesehen sein, dass der überstehende Materialabschnitt auf sich zurückgefaltet ist und die Wicket-Pin-Löcher in diesem doppellagigen Abschnitt angeordnet sind.Since the bag material used cannot be separated and connected by means of cut-off welding, it is particularly advantageous to connect the side edges of the bag to one another over a width of several millimeters by heat sealing. Due to the surfaces of the coating facing the interior and the welding of these opposite sealing coatings, it is sufficient to apply the sealing coating to the paper in a thickness which corresponds to half the sealing material thickness necessary for joining the side edges. It can be provided that the bottom area is provided for removing the hygiene articles. For this purpose, the bottom area can have a perforation. The perforation can in particular be made in the vicinity of the side edges parallel to the longitudinal dimension of the bag. Provision can also be made for the bags to be provided as wicket bags or pen-stack bags for filling with hygiene articles. For this purpose, the bottom area can have an opening facing the interior of the bag. Furthermore, the bottom area can have a protruding material section on the front or the rear wall of the bag. This can be used to close the bag. The protruding material section can also have two wicket pin holes. In order to prevent the material from tearing off when it is pulled from the wicket pin, it can be provided that the protruding material section is folded back on itself and the wicket pin holes are arranged in this double-layered section.
Dabei kann insbesondere vorgesehen sein, dass die miteinander versiegelten Seitenränder als Flachnähte ausgebildet sind. Um die Eigenschaften des siegelfähigen Papiers optimal für den Beutel zu nutzen, bieten sich insbesondere Flachnähte zum Verbinden der beiden Materiallagen an. Dadurch können die Lagen besonders leicht beim Durchlaufen der flachen Materialbahn durch eine Schweißstation beispielsweise durch senkrechtes Absenken von Schweißbalken miteinander verbunden werden. Ferner kann die Nahtbreite so gewählt werden, dass zwei Flachnähte benachbarter Beutel gleichzeitig hergestellt werden und in einem nachfolgenden Schritt getrennt werden können.In particular, it can be provided that the side edges sealed to one another are designed as flat seams. In order to optimally use the properties of the sealable paper for the bag, flat seams are particularly useful for connecting the two layers of material. As a result, the layers can be connected to one another particularly easily when the flat material web runs through a welding station, for example by vertically lowering welding bars. Furthermore, the seam width can be selected so that two flat seams of adjacent bags are produced at the same time and can be separated in a subsequent step.
Außerdem kann vorgesehen sein, dass die vorbestimmte Breite der Seitenränder zwischen 5 bis 15 mm, bevorzugt, 8 bis 12 mm, besonders bevorzugt 10 mm beträgt. Die Nahtbreite kann beispielsweise abhängig von der Beutelgröße oder vom zu verpackenden Artikel gewählt werden, um individuell die notwendige Stabilität bereitstellen zu können.In addition, it can be provided that the predetermined width of the side edges is between 5 to 15 mm, preferably 8 to 12 mm, particularly preferably 10 mm. The seam width can be selected depending on the bag size or the article to be packaged, for example, in order to be able to provide the necessary stability individually.
Ferner kann der Beutel im befüllten Zustand einen durch die vordere und rückseitige Beutelwandung ausgebildeten Körper aufweisen, welcher eine Vorderfläche, eine Rückfläche, zwei die Vorderfläche und die Rückfläche verbindenden Seitenflächen sowie zwei die Vorderfläche und die Rückfläche verbindende und an die Seitenflächen angrenzende Kopf- und Bodenflächen aufweist.Furthermore, in the filled state, the bag can have a body formed by the front and rear bag walls, which body has a front surface, a rear surface, two side surfaces connecting the front surface and the rear surface, and two top and bottom surfaces connecting the front surface and the rear surface and adjoining the side surfaces having.
Darüber hinaus kann vorgesehen sein, dass im befüllten Zustand des Beutels die Flachnähte im Bereich der Seitenflächen verlaufen. Im befüllten Zustand können sich die vordere und die rückseitige Beutelwandung um die verpackten Artikeln herumwölben, so dass die Flachnähte im Bereich von durch die Artikelform erzeugte Seitenflächen verlaufen. Die Flachnähte können dabei senkrecht zu den Seitenflächen abstehen. Ferner können die Flachnähte mittels eines auf diese oder auf entsprechende Abschnitte der Seitenflächen aufgebrachten Siegellacks mit den Seitenflächen heißversiegelt sein.In addition, it can be provided that when the bag is filled, the flat seams run in the area of the side surfaces. In the filled state, the front and the rear bag wall can arch around the packaged articles, so that the flat seams run in the area of the side surfaces produced by the article shape. The flat seams can protrude perpendicular to the side surfaces. Furthermore, the flat seams can be heat-sealed to the side surfaces by means of a sealing lacquer applied to them or to corresponding sections of the side surfaces.
Dabei kann vorgesehen sein, dass an den Übergängen zwischen der Kopffläche und den angrenzenden Seitenflächen jeweils zumindest eine vom Körper abstehende Ecke ausgebildet ist. Durch Befüllen des Beutels mit einer Mehrzahl Artikel, welche im Verbund eine im Wesentlichen würfelförmige Außenkontur aufweisen, passt sich der Beutel an diese Form an und bildet an seinen nicht befüllten Randbereichen nach außen abstehende Ecken aus. Beispielsweise können bei einem Beutel ohne Kopffalte, das heißt, bei Aufeinanderfalten der vorderen und der rückseitigen Beutelwand mittels einer einzigen Umfaltung, zwei Ecken abstehen.It can be provided that at least one corner protruding from the body is formed at the transitions between the top surface and the adjoining side surfaces. By filling the bag with a plurality of articles which, when combined, have an essentially cube-shaped outer contour, the bag adapts to this shape and forms outwardly protruding corners at its unfilled edge areas. For example, in the case of a bag without a head fold, that is to say when the front and the rear bag wall are folded onto one another by means of a single fold, two corners can protrude.
Außerdem kann die im Kopfbereich vorgesehene Faltungsanordnung eine eingelegte Kopffalte aufweisen, so dass an den Übergängen zwischen der Kopffläche und den angrenzenden Seitenflächen jeweils zumindest zwei gegenüberliegende vom Körper abstehende Ecken ausgebildet sind. Die Kopffalte kann insbesondere so ausgebildet sein, dass die Faltenanordnung im Kopfbereich drei Umfaltungen aufweist, so dass eine Falte zwischen vorderer und rückseitiger Beutelwandung eingelegt ist. Die Kopffalte kann beispielsweise dazu dienen, einen Standfuß zu erzeugen, mit welchem der befüllte Beutel aufrecht hingestellt werden kann, ohne umzufallen. Ferner kann die Kopffalte bewirken, dass der Beutel eine ansprechende Optik aufweist beziehungsweise mehr Artikel im Beutel aufgenommen werden können. Bei Vorsehen einer Kopffalte weist der Beutel im Kopfbereich vier anstelle von zwei Ecken auf, welche aufgrund der zwei außenliegenden Umfaltungen der entsprechenden Faltenanordung entstehen.In addition, the folding arrangement provided in the head area can have an inserted head fold, so that at least two opposite corners protruding from the body are formed at the transitions between the head surface and the adjoining side surfaces. The head fold can in particular be designed such that the fold arrangement has three folds in the head area, so that a fold is inserted between the front and rear wall of the bag. The head fold can be used, for example, to create a stand with which the filled bag can be placed upright without falling over. Furthermore, the head fold can have the effect that the bag has an attractive appearance or that more articles can be accommodated in the bag. If a head fold is provided, the bag has four instead of two corners in the head area, which are created due to the two outer folds of the corresponding fold arrangement.
Es kann vorgesehen sein, dass die an den Übergängen zwischen der Kopffläche und den angrenzenden Seitenflächen jeweils zumindest eine vom Körper abstehende Ecke auf die Kopffläche zurückgefaltet ist. Bei der Faltenanordnung ohne Kopffalte kann der Kopfbereich insbesondere zwei Ecken aufweisen. Bei der Faltenanordnung mit Kopffalte kann der Kopfbereich insbesondere vier Ecken aufweisen. Aus optischen und aus räumlichen Gründen kann es dabei sinnvoll sein, die abstehenden Ecken auf den Beutelkörper zurückzufalten.Provision can be made for the at least one corner protruding from the body at the transitions between the head surface and the adjoining side surfaces to be folded back onto the head surface. In the case of the fold arrangement without a head fold, the head area can in particular have two corners. In the case of the fold arrangement with a head fold, the head area can in particular have four corners. For optical and spatial reasons, it can be useful to fold the protruding corners back onto the bag body.
Insbesondere können die auf die Kopffläche zurückgefalteten Ecken mittels eines auf die Papierschicht zumindest örtlich aufgetragenen Siegellacks mit der Kopffläche heißversiegelt sein. Der Siegellack kann dabei jeweils auf die Innenseiten der Ecken und/oder auf die entsprechenden Stellen der Kopffläche punktuell oder flächig aufgebracht sein. Da das Papier nicht "Außen-auf-außen" verschweißt werden kann, bewirkt das Auftragen des Siegellacks auf diese Stellen, dass auch in diesen Bereichen das Material verbunden werden kann.In particular, the corners folded back onto the top surface can be heat-sealed to the top surface by means of a sealing lacquer applied at least locally to the paper layer. The sealing wax can be applied point-wise or flat on the inside of the corners and / or on the corresponding points of the top surface. Since the paper cannot be welded "outside-to-outside", applying the sealing lacquer to these areas means that the material can also be connected in these areas.
Ferner können über eine im Bodenbereich angeordnete, sich in der Querabmessung erstreckende und in einer vorbestimmten Breite die siegelfähige Beschichtung aufweisende Flachnaht die vordere und die rückseitige Beutelwandung miteinander heißversiegelt sein. Dadurch kann der Beutel nach dem Befüllen verschlossen werden. Die vom Beutel abstehende Flachnaht kann beispielsweise durch zumindest abschnittsweises Auftragen und Erhitzen eines Siegellacks auf dem Beutelkörper befestigt werden. Die Breite der Flachnaht kann so bemessen sein, dass im Bodenbereich eine flache Griffleiste ausgebildet ist. Der Griffbereich kann insbesondere nach Befüllen der Beutel ausgebildet werden. Dabei kann unterhalb des Griffs insbesondere eine Schließschweißung zum Abschließen des Innenraums des Beutels erfolgen. Oberhalb des Griffs kann ferner eine Schweißung umfassend einen Abtrennvorgang zum Wicket-Bereich erfolgen.Furthermore, the front and the rear bag wall can be heat-sealed to one another via a flat seam arranged in the bottom area, extending in the transverse dimension and having the sealable coating in a predetermined width. This allows the bag to be closed after filling. The flat seam protruding from the bag can be attached to the bag body, for example, by applying a sealing wax at least in sections and heating it. The width of the flat seam can be dimensioned such that a flat grip strip is formed in the bottom area. The grip area can in particular be formed after the bag has been filled. In particular, a sealing weld can be carried out below the handle to close off the interior of the bag. Above the handle, a weld comprising a separation process to form the wicket area can also take place.
Ferner kann der Beutel eine im Kopfbereich angeordnete Griffleiste aufweisen, welche durch zumindest abschnittsweises Heißversiegeln der vorderen mit der rückseitigen Beutelwandung gebildet ist, wobei sich die Griffleiste über die Querabmessung und ausgehend von der Faltungsanordnung in Längsrichtung in einer vorbestimmten Griffbreite erstreckt. Bei dieser Ausführungsform kann anstelle der eingelegten Kopffalte oder anstelle der Ausbildung des Beutels als Flachbeutel im Kopfbereich eine Griffleiste vorgesehen sein. Die vordere und die hintere Beutelwandung können über den gesamten Bereich der Griffleiste miteinander heißversiegelt sein. Die vordere und die hintere Beutelwandung können auch nur über einen Teilbereich der Griffleiste miteinander heißversiegelt sein.Furthermore, the bag can have a grip strip arranged in the head area, which is formed by at least partially heat-sealing the front and rear bag walls, the grip strip extending over the transverse dimension and starting from the folding arrangement in the longitudinal direction in a predetermined grip width. In this embodiment, a grip strip can be provided in the head area instead of the inserted head fold or instead of the bag being designed as a flat bag. The front and rear bag walls can be heat-sealed to one another over the entire area of the grip strip. The front and rear bag walls can also be heat-sealed to one another only over a partial area of the grip strip.
Dabei kann die vorbestimmte Griffbreite 4-8 cm, bevorzugt 5-7 cm, besonders bevorzugt 8 cm aufweisen.The predetermined grip width can be 4-8 cm, preferably 5-7 cm, particularly preferably 8 cm.
AuĂźerdem kann die Griffleiste einen ausgestanzten Tragegriff aufweisen.In addition, the handle strip can have a punched-out handle.
Ferner wird ein Verfahren zum Herstellen von Beuteln nach einem der vorangehenden AnsprĂĽche beansprucht, aufweisend die folgenden Schritte:
- Bereitstellen einer endlosen Materialbahn, welche eine Papierschicht sowie eine zumindest abschnittsweise, insbesondere vollflächig, auf der Papierschicht angeordnete siegelfähige Beschichtung aufweist, wobei die Materialbahn entlang der Endlosrichtung mit der Papierschicht nach außen weisend über eine Faltungsanordnung aufeinander gefaltet ist;
- Erhitzen der Materialbahn im Bereich von quer zur Endlosrichtung aufzubringenden Siegelnähten, wobei die Siegelnähte zumindest die doppelte vorbestimmte Breite aufweisen;
- Trennen der Materialbahn längs der aufgebrachten Siegelnähte zu einzelnen Beuteln.
- Providing an endless material web which has a paper layer and a sealable coating arranged at least in sections, in particular over the entire surface, on the paper layer, the material web being folded onto one another along the endless direction with the paper layer facing outwards via a folding arrangement;
- Heating the material web in the area of sealing seams to be applied transversely to the endless direction, the sealing seams having at least twice the predetermined width;
- Separation of the material web along the applied sealing seams into individual bags.
Durch das Herstellen von Siegelnähten mit einer Breite, die der doppelten vorbestimmten Breite entspricht, wird ermöglicht, dass pro Siegelungsvorgang zwei Seitennähte aneinander grenzender Beutel gleichzeitig herstellbar sind. Insbesondere kann vorgesehen sein, dass die hergestellten Nähte mittig durchtrennt werden.By producing sealing seams with a width which corresponds to twice the predetermined width, it is possible for two side seams of adjacent bags to be produced at the same time per sealing process. In particular, it can be provided that the seams produced are severed in the middle.
Dabei kann das Erhitzen der Materialbahn ein Vorwärmen der aufzubringenden Siegelnähte umfassen. Alternativ kann bereits das Erhitzen das Heißversiegeln der Siegelnähte umfassen.The heating of the material web can include preheating of the sealing seams to be applied. Alternatively, the heating can already include the heat sealing of the sealing seams.
Dabei kenn der Verfahrensschritt des Trennens der Siegelnähte ein Fixieren der Materialbahn umfassen. Vorzugsweise erfolgt das Fixieren vor dem Trennen der Siegelnähte.The process step of separating the sealing seams can include fixing the material web. The fixing preferably takes place before the sealing seams are separated.
Außerdem kann das Trennen der Siegelnähte ein erneutes Erhitzen der Siegelnähte zum Heißversiegeln der aufeinandergefalteten Materialbahnschichten umfassen. Insbesondere kann vorgesehen sein, dass das gegebenenfalls erste Erhitzen der Materialbahn und das Trennen der Siegelnähte an separaten Stationen erfolgt.In addition, the severing of the sealing seams can comprise a renewed heating of the sealing seams in order to heat-seal the material web layers which have been folded onto one another. In particular, it can be provided that the possibly first heating of the material web and the severing of the sealing seams take place at separate stations.
