Der zunächst flachliegende Folienbeutel wird in Beutelfülleinrichtungen mit Füllgut beschickt. Die Befüllung erfolgt am Kopf des Beutels. Das Füllgut wird in eine Öffnung, die noch zwischen dem Wiederverschluss und einer Frontseite des Folienbeutels vorhanden ist, eingeführt. Danach wird diese Öffnung durch eine Siegelnaht verschlossen. Folienbeutel mit den beschriebenen Merkmalen werden unter anderem zur Verpackung von Tierfutter verwendet.wherein one of the profile strips is connected to a front side and the other profile strip is connectable after filling the bag with the other front side, wherein the superimposed layers of film of the bag with transverse and longitudinal sealing seams on the bottom side and along the edges of the gussets are connected and wherein along the Gussets extending longitudinal sealing seams extending from the bottom to the top of the bag. The initially flat foil bag is filled with filling material in bag filling devices. The filling takes place at the head of the bag. The contents are introduced into an opening which is still present between the reclosure and a front side of the film bag. Thereafter, this opening is closed by a sealed seam. Foil bags with the described features are used, inter alia, for packaging animal feed.
Ein Folienbeutel mit den beschriebenen Merkmalen ist aus DE 202 07 333 U1 bekannt. Der Schieber des Wiederverschlusses übergreift Verschlusskanten der Profilstreifen reiterartig und steht an der Oberseite des Beutels vor. Die Profilstreifen sind an ihrem dem Schieber gegenüberliegenden Ende miteinander verbunden und bilden einen Originalitätsverschluss, der beim erstmaligen Gebrauch des Folienbeutels aufreißbar ist. Nachteilig ist, dass von außen nicht ohne weiteres ersichtlich ist, ob der Originalitätsverschluss noch unbeschädigt ist. Ferner besteht die Gefahr, dass der vorstehende Schieber beim Transport des Beutels oder bei seiner Handhabung im Handel an Widerständen hängen bleibt und sich dabei unkontrolliert verschiebt. Die Fertigung des Folienbeutels ist ebenfalls aufwendig. Im Anschluss an die Beutelher- Stellung werden in einem nachgeschalteten Anlagenteil die Wiederverschlüsse appliziert. Dazu wird ein Folienabschnitt des bereits gefertigten Folienbeutels im Kopfbereich des Beutels aufgeklappt, ein Wiederverschluss auf die darunter liegende Folienbahn aufgelegt und mit dieser verbunden. Danach müssen der aufgeklappte Folienabschnitt zurückgefaltet und die noch fehlenden Siegel- nähte angebracht werden. Zur Applikation der Wiederverschlüsse müssen bestehende Anlagen zur Herstellung von Folienbeuteln durch eine zusätzliche Anlage zur Applikation der Wiederverschlüsse erweitert werden. Die zusätzliche Anlage zur Applikation der Wiederverschlüsse ist aufwendig und erfordert einen erheblichen Platz. Insofern besteht auch ein Bedürfnis, Applikationen von Wiederverschlüssen in das übliche Beutelherstellungsverfahren zu integrieren.A foil bag with the described features is known from DE 202 07 333 U1. The slider of the reclosure overlaps closure edges the profile strip rider-like and protrudes at the top of the bag. The profile strips are connected to each other at their opposite end of the slider and form a tamper-evident, which is torn when first using the foil bag. The disadvantage is that from the outside is not readily apparent whether the tamper-evident closure is still undamaged. Furthermore, there is a risk that the projecting slide will hang on resistors during transport of the bag or its handling in the trade and thereby shifts uncontrollably. The production of the foil bag is also expensive. Following the Beutelher- position the reclosures are applied in a downstream part of the plant. For this purpose, a film section of the already fabricated film bag is unfolded in the head region of the bag, placed a reclosure on the underlying film web and connected to this. Afterwards the unfolded film section must be folded back and the missing sealing seams must be applied. To apply the reseals, existing systems for the production of film bags must be extended by an additional system for applying the reseals. The additional system for applying the reclosures is expensive and requires considerable space. As such, there is also a need to integrate reseal applications in the standard bag making process.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Folienbeutel anzugeben, der einen verdeckt angeordneten Schieberverschluss aufweist und sich einfach herstellen lässt. Ferner soll ein Verfahren angegeben werden, bei dem die Applikation der Wiederverschlüsse während des kontinuierlichen Bahnvorlaufs einer ebenen Folienbahn vor der Beutelformung erfolgt.Against this background, the invention has for its object to provide a foil bag, which has a concealed slide closure and can be easily produced. Furthermore, a method is to be specified in which the application of the reclosures during the continuous web advance of a flat film web takes place before the bag is formed.
Ausgehend von einem Folienbeutel mit den eingangs beschriebenen Merk- malen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass der Wiederverschluss einschließlich seines Schiebers mit Abstand zum oberen Beutelrand innerhalb des Beutels angeordnet ist und dass zumindest eine Frontseite des Beutels eine an die Abmessung des Schiebers angepasste Schieberausstan- zung enthält, in welcher der Schieber vor dem erstmaligen Gebrauch des Beutels positioniert ist. Erfindungsgemäß ist der Wiederverschluss im Kopfbereich des Folienbeutels verdeckt angeordnet, wobei der Schieber durch die Schieberausstanzung sichtbar bleibt. Für den Verbraucher ist damit sofort von außen erkennbar, dass der Beutel mit einem Schieberverschluss ausgerüstet ist und der Schieberverschluss ordnungsgemäß geschlossen ist. Darüber hinaus erfüllt die Schieberausstanzung eine wichtige Funktion bei der Folien- beutelherstellung. Die Schieberausstanzung, welche an die Größe des Schiebers angepasst ist und diesen umschließt, ermöglicht eine Applikation des Wiederverschlusses auf einer ebenen Folienbahn, bevor diese Faltstationen durchläuft, in denen die Folienbahn umgefaltet wird und Seitenfalten eingeformt werden. Die Schieberausstanzung sitzt genau an der Position des Schiebers und verhindert beim Bahnlauf über Führungsbleche der Faltstationen eine Ver- Schiebung des Wiederverschlusses entgegen der Folienlaufrichtung.Starting from a foil pouch with the features described in the introduction, the object is achieved according to the invention in that the reclosure, including its slide, is arranged at a distance from the upper edge of the pouch within the pouch and at least one front side of the pouch The bag contains a pusher fitting adapted to the size of the pusher in which the pusher is positioned prior to the first use of the bag. According to the reclosure in the head region of the film bag is arranged concealed, the slider remains visible through the Schieberausstanzung. For the consumer it is immediately apparent from the outside that the bag is equipped with a slide closure and the slide closure is properly closed. In addition, the slide punching fulfills an important function in the production of film pouches. The Schieberausstanzung, which is adapted to the size of the slider and encloses this, allows application of the reclosure on a flat sheet of film before passing through these folding stations, in which the film web is folded and gussets are formed. The slide punching is located exactly at the position of the slide and prevents during web travel on guide plates of the folding stations a displacement of the reclosure against the direction of film travel.
Die Frontseiten des Folienbeutels weisen am oberen Ende des Beutels einen den Wiederverschluss verdeckenden streifenförmigen Abschnitt auf, der gemäß einer bevorzugten Ausführung der Erfindung entlang einer etwa in Höhe des Schiebers oder unterhalb des Schiebers angeordneten Perforationslinie abreißbar ist. An den Enden der Perforationslinie schließen zweckmäßig Stanzlinien an, die sich durch die Längssiegelnähte bis zu den Außenkanten des Beutels erstrecken. Der Streifen kann bei der beschriebenen Ausgestaltung vollständig und auf einfache Weise von dem Folienbeutel als Abfallstreifen entfernt werden, wenn ein Folienbeutel erstmals in Gebrauch genommen wird. Um das Abtrennen des Streifens zu erleichtem, ist es zweckmäßig, wenn die Seitenfalten unterhalb der Perforationslinie enden.The front sides of the film bag have at the upper end of the bag on a reclosing occlusive strip-shaped portion which can be torn off according to a preferred embodiment of the invention along a arranged approximately at the level of the slider or below the slider line of perforation. At the ends of the perforation line suitably include punching lines which extend through the longitudinal sealing seams to the outer edges of the bag. The strip can be completely and easily removed from the foil bag as a waste strip in the described embodiment, when a foil bag is first taken into use. In order to facilitate the separation of the strip, it is useful if the gussets end below the perforation line.
Der entlang der Perforationslinie abreißbare Abfallstreifen kann auch die Funk- tion eines Originalitätsverschlusses erfüllen, wenn der doppellagige Streifen nach der Befüllung des Folienbeutels an seinem oberen Rand mit einer Quersiegelnaht versiegelt wird. Bei erstmaliger Ingebrauchnahme des Folienbeutels muss der oberseitige Streifen abgetrennt werden, wobei der Wiederverschluss am oberen Rand des Folienbeutels freigelegt wird. Ist die Quersiegelnaht des Abfallstreifens unbeschädigt, so ist sichergestellt, dass der Folienbeutel zuvor nicht geöffnet worden ist.The tear-off strip along the perforation line can also fulfill the function of a tamper-evident closure if the double-layered strip is sealed with a transverse sealing seam at its upper edge after the film bag has been filled. When first putting the foil bag into use the top strip must be severed exposing the reclosure at the top of the foil bag. If the transverse sealing seam of the waste strip is undamaged, it is ensured that the foil bag has not previously been opened.
Im Rahmen der Erfindung liegt es, dass der vor einer Beutelbefüllung mit der Frontseite verbundene Profilstreifen auf seiner gesamten Länge nur mit der Frontseite verbunden ist und sich bis in den Bereich der Seitenfalten erstreckt. Bei dieser Ausführung lässt sich der Beutel zum Befüllen an seiner Oberseite vollständig öffnen. Eine alternative Ausführung sieht vor, dass der vor einer Beutelbefüllung mit der Frontseite verbundene Profilstreifen über die Seitenfalten gelegt und mit diesen verbunden ist. Bei dieser Ausführung ist die Be- füllöffnung etwas geringer.It is within the scope of the invention that the profile strip connected to the front before bag filling is connected over its entire length only to the front side and extends into the region of the side folds. In this embodiment, the bag can be fully opened for filling at its top. An alternative embodiment provides that the profile strip connected to the front before bag filling is laid over the side folds and connected to them. In this embodiment, the filling opening is slightly smaller.
Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung des beschriebenen Folienbeutels. Das erfindungsgemäße Verfahren weist folgende Verfahrensschritte auf:The invention also provides a process for producing the film bag described. The method according to the invention comprises the following method steps:
a) in eine ebene Folienbahn werden Schieberausstanzungen einge- bracht;a) Schieberausstanzungen be introduced into a flat film web;
b) Wiederverschlüsse bestehend aus zwei aufeinanderliegenden und miteinander verbundenen Profilstreifen sowie einem Schieber, der Verschlusskanten der Profilstreifen reiterartig übergreift, werden quer zur Bahnrichtung so auf die ebene Folienbahn aufgelegt, dass die Schieber in den Schieberausstanzungen liegen, und werden an den Enden mit der Folienbahn verbunden;b) reclosing consisting of two superimposed and interconnected profile strips and a slider which engages over tabs of the profile strip like a rider are placed transversely to the web direction on the flat film web that the slides are in the Schieberausstanzungen, and are connected at the ends of the film web ;
c) anschließend wird die Folienbahn durch Faltstationen geführt, in denen die Folienbahn gefaltet wird und Seitenfalten gebildet werden; d) die aufeinanderliegenden Folienlagen der Folienbahn werden durch Siegelnähte verbunden, wobei mit Quersiegelnähten quer zur Bahnrichtung der Boden der Beutel gebildet und die Wiederverschlüsse mit einer Frontseite der Beutel verbunden werden und wobei entlang den Seitenfalten Längssiegelnähte in Bahnlängsrichtung angebracht werden, die sich vom Boden bis zum oberen Rand der Beutel erstrecken;c) then the film web is passed through folding stations, in which the film web is folded and gussets are formed; d) the superimposed film layers of the film web are joined by sealing seams, formed with transverse sealing seams transverse to the web direction of the bottom of the bag and the reclosures are connected to a front side of the bag and along the side pleats longitudinal sealing seams are attached in the web longitudinal direction extending from the ground to the extend the upper edge of the bag;
e) von dem im Verfahrensschritt d) gebildeten Beutelstrang werden Beutel abgetrennt.e) bags are separated from the bag strand formed in process step d).
Der Erfindung liegt die Überlegung zugrunde, die Wiederverschlüsse auf der ebenen Folienbahn zu applizieren, bevor die Folienbahn Faltstationen durchläuft, in denen sie gefaltet wird und Seitenfalten gebildet werden. Die erfin- dungsgemäße Applikation der Wiederverschlüsse kann in vorhandene Beutelherstellungsanlagen integriert werden. Das erfindungsgemäße Verfahren macht Gebrauch von den in einer Beutelherstellungsanlage bereits vorhandenen Stanzeinrichtungen und Umfalteinrichtungen. Dabei ist allerdings das technische Problem zu lösen, dass sich die Wiederverschlüsse beim Transport der Folienbahn durch die Anlage, insbesondere in den Umfalteinrichtungen, verschieben können, da die Wiederverschlüsse zunächst nur an den Enden mit der Folienbahn verbunden werden. Zwischen den Profilstreifen der Wiederverschlüsse und der Folienbahn muss eine Öffnung bleiben, damit die Beutel am kopfseitigen Ende befüllt werden können. Erst nach der Beutelbefüllung wird diese Öffnung durch Verschweißen des Profilstreifens mit der Frontseite des Folienbeutels geschlossen. Das beschriebene technische Problem wird erfindungsgemäß durch den Verfahrensschritt b) gelöst. Erfindungsgemäß werden in die Folienbahn Schieberausstanzungen eingebracht, die genau an der Position der Schieber liegen und beim Bahnlauf durch die Beutelherstellungs- anläge, insbesondere auch beim Bahnlauf über die Führungsbleche von Faltstationen, eine Verschiebung der Wiederverschlüsse und der Schieber entgegen der Folienlaufrichtung verhindern. Die Schieber sind in den zugeord- neten Schieberausstanzungen gleichsam fixiert. Bei den Schieberausstan- zungen handelt es sich im einfachsten Fall um runde Löcher, deren Durchmesser an die Schiebergeometrie angepasst ist.The invention is based on the idea of applying the reseals to the flat film web before the film web passes through folding stations in which it is folded and gussets are formed. The application of the reclosures according to the invention can be integrated into existing bag production systems. The inventive method makes use of the already existing in a bag making plant punching and Umfalteinrichtungen. In this case, however, the technical problem to be solved is that the reclosures during transport of the film web through the system, in particular in the Umfalteinrichtungen move, since the reclosures are initially connected only at the ends of the film web. There must be an opening between the profile strips of the reclosures and the film web so that the bags can be filled at the head end. Only after the bag filling this opening is closed by welding the profile strip with the front side of the film bag. The technical problem described is achieved by the method step b). According to the slide slide punches are introduced into the film web, which lie exactly at the position of the slide and during web travel through the Beutelherstellungs- anläge, especially during web travel on the guide plates of folding stations, prevent displacement of the reclosures and the slide against the film travel direction. The sliders are in the assigned Neten Schieberausstanzungen as it were fixed. In the simplest case, the slide expansions are round holes whose diameters are adapted to the slide geometry.
Gemäß einer bevorzugten Ausführung der Erfindung werden in Zonen der ebenen Folienbahn, aus denen die Seitenfalten gebildet werden, fensterförmige Aussparungen eingestanzt, welche das obere Ende der Beutelseitenfalten begrenzen. Zweckmäßig werden ferner in die ebene Folienbahn quer zur Bahnlängsrichtung Perforationslinien eingestanzt, die in Höhe der fensterförmigen Aussparungen angeordnet sind und im Beutelstrang jeweils einen streifenförmigen Abschnitt begrenzen, der über den Schieber des Wiederverschlusses bis zur Bodensiegelnaht des benachbarten Beutels übersteht. Der Streifen kann als Originalitätsverschluss genutzt werden. Vor dem erstmaligen Gebrauch eines Beutels wird der Streifen abgerissen, wobei der Schieber des Wiederver- Schlusses freigelegt wird. Die fensterförmigen Aussparungen ebenso wie die Perforationslinien werden in die ebene Folienbahn eingebracht, bevor diese Faltstationen durchläuft, in denen sie umgefaltet wird und Seitenfalten eingeformt werden. Hierbei besteht das technische Problem, dass die Folienbahn in den Faltstationen an den Perforationslinien und fensterförmigen Ausstanzungen einreißen kann, wenn die Formwerkzeuge in die Perforation oder Ausstanzungen greifen und die Folienbahn an den Werkzeugen hängen bleibt. Dieses Problem lässt sich auf überraschend einfache Weise dadurch lösen, dass die Perforationslinien sich zwar im Wesentlichen über die Bahnbreite erstrecken, jedoch mit der Maßgabe, dass zwischen der Perforation und den fenster- förmigen Aussparungen jeweils ein 5 mm bis 50 mm breiter nicht perforierter Folienbereich verbleibt. Die Folienbahn wird in den Faltstationen so geführt, dass die Kanten der Faltwerkzeuge an den nicht perforierten Folienbereichen zwischen der Perforation und den Aussparungen anliegen. Die Umfaltung der Folienbahn zu einer schlauchförmigen Bahn erfolgt unter Verwendung von dreieckförmigen Umfaltblechen. Wenn die fensterförmigen Ausstanzungen mittig über die dreieckförmigen Bleche geführt werden, bleiben sie überraschenderweise nicht an den Blechen hängen. In die Längssiegelnähte können schließlich noch Stanzschnitte eingebracht werden, die an die Perforationslinien anschließen.According to a preferred embodiment of the invention, in zones of the flat film web, from which the side folds are formed, window-shaped recesses are punched, which delimit the upper end of the bag side folds. Appropriately be perforated in the flat film web transverse to the web longitudinal direction perforation lines, which are arranged at the level of the window-shaped recesses and each define a strip-shaped section in the bag strand, which projects beyond the slide of the reclosure to the bottom seam of the adjacent bag. The strip can be used as a tamper evident closure. Before the first use of a bag, the strip is torn off, exposing the slider of the re-closure. The window-shaped recesses as well as the perforation lines are introduced into the flat film web before it passes through these folding stations, in which it is folded over and gussets are formed. In this case, there is the technical problem that the film web can tear in the folding stations on the perforation lines and window-shaped punched out when the molds engage in the perforation or punching and the film web gets caught on the tools. This problem can be solved in a surprisingly simple way by the fact that the perforation lines extend essentially over the web width, but with the proviso that between the perforation and the window-shaped recesses in each case a 5 mm to 50 mm wide non-perforated film area remains , The film web is guided in the folding stations so that the edges of the folding tools abut the non-perforated film areas between the perforation and the recesses. The folding of the film web into a tubular web is carried out using triangular Umfaltblechen. If the window-shaped cutouts are centered over the triangular sheets, they surprisingly do not stick to the sheets. In the longitudinal sealing seams finally punched cuts can be introduced, which connect to the perforation lines.

Die Frontseiten 1 , 1' weisen am oberen Ende des Beutels einen den Wiederver- Schluss 3 verdeckenden streifenförmigen Abschnitt 9 auf, der entlang einer etwa in Höhe des Schiebers 5 oder unterhalb des Schiebers angeordneten Perforationslinie 10 abreißbar ist. An den Enden der Perforationslinie 10 schließen Stanzlinien 11 an, die sich durch die Längssiegelnähte 6 bis zu den Außenkanten des Beutels erstrecken. Die Seitenfalten 2 enden unterhalb der Perforationslinie 10. Der streifenförmige Abschnitt 9 ist entlang der Perforationslinie 10 und den anschließenden Stanzlinien 11 von dem Folienbeutel abtrennbar. Dabei wird der Wiederverschluss 3 freigelegt.The front sides 1, 1 'have at the upper end of the bag a strip-like section 9 covering the reclosure 3, which can be torn off along a perforation line 10 arranged approximately at the level of the slider 5 or below the slider. At the ends of the perforation line 10 close punching lines 11, which extend through the longitudinal sealing seams 6 to the outer edges of the bag. The gussets 2 terminate below the perforation line 10. The strip-shaped portion 9 can be separated along the perforation line 10 and the subsequent punching lines 11 of the foil bag. The re-closure 3 is exposed.
Die in Fig. 1 dargestellten Folienbeutel werden beispielsweise zum Verpacken von Tierfutter eingesetzt. Die Befüllung erfolgt am Kopf des Beutels. Das Füllgut wird in eine Öffnung, die noch zwischen dem Wiederverschluss 3 und einer Frontseite 1' des Folienbeutels vorhanden ist, eingeführt. Danach wird diese Öffnung durch eine Siegelnaht verschlossen. Zusätzlich wird als Originalitäts- verschluss der obere Rand des streifenförmigen Abschnittes 9, der beim erst- maligen Gebrauch des Folienbeutels abgerissen wird, versiegelt. Die Versiegelung erfolgt mit einer Quersiegelnaht 12, welche die Folienlagen verbindet. In der Beutelbefüllanlage wird der Boden des Folienbeutels noch zu einem Standboden umgefaltet. Die Fig. 2 zeigt den befüllten Standbodenbeutel.The film bags shown in Fig. 1 are used for example for packaging animal feed. The filling takes place at the head of the bag. The contents are introduced into an opening which is still present between the reclosure 3 and a front side 1 'of the film bag. Thereafter, this opening is closed by a sealed seam. In addition, the top edge of the strip-shaped section 9, which is torn off when the foil bag is used for the first time, is sealed as a tamper-evident closure. The sealing takes place with a transverse sealing seam 12, which connects the film layers. In the Beutelbefüllanlage the bottom of the film bag is folded over to a floor stand. Fig. 2 shows the filled stand-up pouch.
Das Verfahren zur Herstellung der in Fig. 1 dargestellten flachgelegten Folienbeutel ist schematisch in Fig. 3 dargestellt. In eine ebene Folienbahn 13 werden Schieberausstanzungen 8 eingebracht. Auf die mit Schieberausstanzungen 8 versehene Folienbahn 13 werden Wiederverschlüsse 3 bestehend aus zwei aufeinanderliegenden und miteinander verbundenen Profilstreifen 4, 4" sowie einem Schieber 5, der Verschlusskanten der Profilstreifen 4, 41 reiterartig übergreift, quer zur Bahnrichtung so auf die ebene Folienbahn 13 aufgelegt, dass die Schieber 5 in den Schieberausstanzungen 8 liegen. Die Profilstreifen 4, 4' werden lediglich an den Enden mit der Folienbahn 13 verbunden. Anschließend durchläuft die Folienbahn 13 Faltstationen, in denen die Folienbahn 13 zu einem Schlauch gefaltet wird und Seitenfalten 2 gebildet werden. In Siegelstationen 15 werden die aufeinanderliegenden Folienlagen der Folienbahn durch Siegelnähte 6, 16, 16' verbunden, wobei mit Quersiegelnähten 16, 16' quer zur Bahnrichtung der Boden der Beutel gebildet und die Wiederverschlüsse 3 mit einer Frontseite 1 der Beutel verbunden werden und wobei entlang den Seitenfalten 2 Längssiegelnähte 6 in Bahnlängsrichtung angebracht werden, die sich vom Boden bis zum oberen Rand 7 der Beutel erstrecken. Auf diese Weise entsteht ein Beutelstrang 17 aus Beuteln, die am boden- bzw. kopfseitigen Ende zusammenhängen. Von dem Beutelstrang 17 werden schließlich die Beutel abgetrennt.The process for producing the flattened foil pouches shown in FIG. 1 is shown schematically in FIG. In a flat film web 13 Schieberausstanzungen 8 are introduced. On the provided with Schieberausstanzungen 8 film web 13 reclosures 3 consisting of two superimposed and interconnected profile strips 4, 4 "and a slider 5, the locking edges of the profile strips 4, 4 1 like a rider engages across the web direction on the flat film web 13, the slides 5 lie in the slide punch-outs 8. The profile strips 4, 4 ' are connected only at the ends of the film web 13. Subsequently, the film web passes through 13 folding stations, in which the film web 13 is folded into a tube and gussets 2 are formed. In sealing stations 15, the superimposed film layers of the film web by sealing seams 6, 16, 16 'are connected, formed with transverse sealing seams 16, 16' transverse to the web direction of the bottom of the bag and the reclosures 3 are connected to a front side 1 of the bag and wherein along the Gussets 2 longitudinal sealing seams 6 are mounted in the web longitudinal direction, which extend from the bottom to the upper edge 7 of the bag. In this way, a bag string 17 of bags, which are connected at the bottom or head end. From the bag string 17, the bags are finally separated.
Insbesondere aus Fig. 4 wird deutlich, dass in Zonen 18 der ebenen Folienbahn 13, aus denen die Seitenfalten 2 gebildet werden, fensterförmige Aussparungen 19 ausgestanzt werden, welche das obere Ende der Beutelseitenfalten begrenzt. Außerdem werden in die ebene Folienbahn 13 quer zur Bahnlängs- richtung Perforationslinien 10 eingestanzt, die in Höhe der fensterförmigen Aussparungen 19 angeordnet sind und im Beutelstrang 17 jeweils einen Quer- streifen bzw. streifenförmigen Abschnitt 9 begrenzen, der über den Schieber 5 des Wiederverschlusses 3 bis zur Bodensiegelnaht 16 des benachbarten Beutels übersteht. Dabei entnimmt man der Fig. 4, dass die Perforationslinie 10 sich über die Bahnbreite mit der Maßgabe erstreckt, dass zwischen den Enden der Perforation und den fensterförmigen Aussparungen 19 jeweils ein 5 mm bis 50 mm breiter nicht perforierter Folienbereich 20 verbleibt. Die nicht perforierten Folienbereiche 20 zwischen der Perforation und den fensterförmigen Aussparungen 19 verhindern, dass die Folienbahn 13 in den Faltstationen 14 aufreißt. In die Längssiegelnähte 6 werden noch Stanzschnitte bzw. Stanzlinien 11 eingebracht, die an die Perforationslinien 10 anschließen.In particular, from Fig. 4 it is clear that in zones 18 of the flat sheet of film 13, from which the gussets 2 are formed, window-shaped recesses 19 are punched, which limits the upper end of the bag side folds. In addition, perforation lines 10 are punched transversely to the web longitudinal direction in the flat film web 13, which are arranged at the level of the window-shaped recesses 19 and each define a transverse strip or strip-shaped section 9 in the bag string 17, via the slide 5 of the reclosure 3 bis to the bottom seam 16 of the adjacent bag protrudes. 4 that the perforation line 10 extends over the web width with the proviso that between the ends of the perforation and the window-shaped recesses 19 each have a 5 mm to 50 mm wide non-perforated film portion 20 remains. The non-perforated film regions 20 between the perforation and the window-shaped recesses 19 prevent the film web 13 from tearing in the folding stations 14. In the longitudinal sealing seams 6 still punching cuts or punching lines 11 are introduced, which connect to the perforation lines 10.
In dem in Fig. 1 dargestellten Ausführungsbeispiel ist der vor einer Beutelfüllung mit der Frontseite 1 verbundene Profilstreifen 4 über die Seitenfalten 2 gelegt und mit diesen verbunden. Im Rahmen der Erfindung liegt es auch, dass der vor einer Beutelbefüllung mit der Frontseite 1 verbundene Profilstreifen 4 auf seiner gesamten Länge nur mit der Frontseite 1 verbunden ist und sich bis in den Bereich der Seitenfalten 2 erstreckt. In the exemplary embodiment illustrated in FIG. 1, the profile strip 4 connected to the front side 1 prior to a bag filling is placed over the gussets 2 and connected with them. It is also within the scope of the invention that the profiled strip 4 connected to the front side 1 before a bag is filled is connected only to the front side 1 over its entire length and extends into the region of the lateral folds 2.
