Des Weiteren betrifft die Erfindung ein Verfahren zur Herstellung eines Beutels mit einer Vorderwand und einer zur Vorderwand parallel angeordneten Rückwand, einem in die Ebene der Wände faltbaren Boden, so dass ein einseitig offener Füllraum sich ergibt, und einem Tragegriffpaar, das an der Vorderwand und der Rückwand befestigt ist.The invention relates to a bag with a front wall and a rear wall arranged parallel to the front wall, a bottom which can be folded into the plane of the walls, so that there is a filling space open on one side, and a pair of handles which are fastened to the front wall and the rear wall. Furthermore, the invention relates to a method for producing a bag with a front wall and a rear wall arranged parallel to the front wall, a bottom which can be folded into the plane of the walls, so that a filling space which is open on one side results, and a pair of handles which are attached to the front wall and the Rear wall is attached.

Aus der EP 0 781 710 A1 ist ein Beutel mit einem Tragegriff offenbart, wobei der Beutel zwei parallele Wände und einen in die Ebene der Wände faltbaren Boden aufweist. Die zwei Tragegriffe weisen jeweils zwei parallele Schenkel und einen diese verbindenden Steg auf. Zudem weisen die Tragegriffe an ihren Schenkeln ausgebildete Befestigungsabschnitte auf, die an den Außenwänden des Beutels befestigt sind, wodurch die eigentliche Befestigung der Tragegriffe erzielt wird. Zudem weist der Tragegriff Faltlinien auf, so dass der Tragegriff zurückfaltbar ist, so dass beide Tragegriffe im zurückgefalteten Zustand nicht über die Wände des Beutels hinaus vorspringen.From the EP 0 781 710 A1 discloses a bag with a handle, the bag having two parallel walls and a bottom foldable into the plane of the walls. The two handles each have two parallel legs and a web connecting them. In addition, the handles have fastening sections formed on their legs, which are fastened to the outer walls of the bag, as a result of which the actual fastening of the handles is achieved. In addition, the handle has fold lines so that the handle can be folded back, so that both handles do not protrude beyond the walls of the bag when folded back.

Darüber hinaus ist aus der Schrift US 2,985,355 A ein Beutel und ein Verfahren zur Herstellung eines Beutels offenbart, wobei der Beutel eine Vorderwand und eine parallel zur Vorderwand angeordnete Rückwand aufweist sowie einen in die Ebene der Wände faltbaren Boden. Damit entsteht ein einseitig offener Füllraum. Ferner offenbart der Beutel ein Tragegriffpaar, das an der Vorderwand und der Rückwand gemäss dem Oberbegriff von Anspruch 1 befestigt ist.It is also from Scripture US 2,985,355 A discloses a pouch and a method for producing a pouch, the pouch having a front wall and a rear wall arranged parallel to the front wall and a base which can be folded into the plane of the walls. This creates a filling space that is open on one side. Furthermore, the bag discloses a pair of handles which are attached to the front wall and the rear wall according to the preamble of claim 1.

Zwar wird auf diese Weise die Bildung eines kompakten Stapels oder Paketes aus flach übereinander liegenden Beuteln ermöglicht, doch kommt es beim Stapeln im Bereich der Tragegriffpaare, insbesondere wenn außenseitig am Beutel befestigt, zu einem verhältnismäßig starken Materialaufbau. Hierdurch wird die Stapelung der Beutel und die Verpackung zu einem kompakten Paket erschwert. Zudem hat sich gezeigt, dass bei der Herstellung der Tragegriffpaare zu vermeidender Abfall entsteht.In this way, the formation of a compact stack or package of bags lying flat one above the other is made possible, but when stacking in the area of the pairs of handles, particularly when attached to the outside of the bag, a relatively strong material build-up occurs. This makes it difficult to stack the bags and package them into a compact package. In addition, it has been shown that waste to be avoided is produced during the manufacture of the pairs of handles.

Die Aufgabe der vorliegenden Erfindung ist es, die oben genannten Nachteile zu vermeiden, insbesondere einen Beutel, sowie ein Verfahren zur Herstellung von Beuteln und ein Maschinensystem zur Herstellung von Beuteln zu schaffen, bei dem sich der Beutel besser stapeln lässt und die Bildung kompakterer Stapel oder Pakete möglich ist. Zudem soll die Effizienz zur Herstellung des Beutels erhöht werden.The object of the present invention is to avoid the disadvantages mentioned above, in particular to create a bag, as well as a method for producing bags and a machine system for producing bags, in which the bag can be stacked better and the formation of more compact stacks or Packages is possible. In addition, the efficiency for the production of the bag is to be increased.

Diese Aufgaben werden erfindungsgemäß durch sämtliche Merkmale der Patentansprüche 1 und 12 gelöst. In den jeweiligen abhängigen Ansprüchen sind bevorzugte Ausführungsformen beschrieben.According to the invention, these objects are achieved by all the features of claims 1 and 12. Preferred embodiments are described in the respective dependent claims.

Erfindungsgemäß ist vorgesehen, dass das Tragegriffpaar in eine Gebrauchsstellung und in eine Ruhestellung bringbar ist, wobei in der Ruhestellung das Tragegriffpaar vollständig innerhalb des Füllraumes zurückgefaltet ist und in der Gebrauchsstellung das Tragegriffpaar zumindest bereichsweise aus dem Füllraum herausragt, wobei das Tragegriffpaar eine Faltlinie aufweist, die in der Gebrauchsstellung im und/oder am Füllraum angeordnet ist. Ein wesentlicher Vorteil der Erfindung ist, dass in der Ruhestellung der Tragegriffpaare ein sehr flacher Beutel im zusammengefalteten Zustand erreicht wird, der einen geringen Materialaufbau beim Stapeln der Beutel benötigt. Die Tragegriffpaare sind erfindungsgemäß flach ausgebildet und begünstigen somit ein geringes Transportvolumen. Ein weiterer Vorteil der innerhalb des Füllraumes gefalteten Tragegriffpaare ist, dass während des Transports oder beim Stapeln der Beutel nicht die Gefahr besteht, dass die Tragegriffpaare beschädigt werden.According to the invention it is provided that the pair of handles can be brought into a position of use and into a rest position, the pair of handles being folded back completely within the filling space in the rest position and the pair of handles protruding at least in regions from the filling space in the position of use, the pair of handles being one Has fold line which is arranged in the use position in and / or on the filling space. A major advantage of the invention is that when the pairs of handles are in the rest position, a very flat bag in the folded state is achieved, which is a small one Material build-up required when stacking the bags. The pairs of handles are flat according to the invention and thus favor a small transport volume. Another advantage of the pairs of handles that are folded within the filling space is that there is no risk of the pairs of handles being damaged during transport or when the bags are being stacked.

Erfindungsgemäß ist es ferner vorgesehen, dass das Tragegriffpaar zwei Griffe aufweist, die innerhalb des Füllraumes an der Vorderwand und der Rückwand befestigt sind, wobei ein Griff an der Innenseite der Vorderwand und der weitere Griff an der Innenseite der Rückwand befestigt ist. Vorteilhafterweise bilden die Griffe in ihrer Gebrauchsstellung fluchtende Grifföffnungen, wodurch der Tragekomfort für den Benutzer wesentlich erhöht ist. Zudem ist es denkbar, dass jeder Griff aus mehreren Materiallagen gebildet ist, wodurch das Tragegriffpaar materialverstärkt ist.According to the invention, it is further provided that the pair of carrying handles has two handles which are fastened to the front wall and the rear wall within the filling space, one handle being fastened to the inside of the front wall and the further handle being fastened to the inside of the rear wall. In their position of use, the handles advantageously form aligned handle openings, as a result of which the wearing comfort for the user is significantly increased. In addition, it is conceivable that each handle is formed from several layers of material, whereby the pair of handles is reinforced.

Zudem ist es erfindungsgemäß, dass der Griff ein Teil eines Trägerelementes ist, das an der Innenseite der Vorderwand oder/oder an der Innenseite der Rückwand befestigt ist. Im Rahmen des erfindungsgemäßen Beutels schließt die Erfindung mit ein, dass das Trägerelement als Zettel ausgeführt ist. Besonders vorteilhaft ist, dass dieses Trägerelement günstig herzustellen ist, wobei gleichzeitig eine innenseitige Befestigung des Trägerelementes an der Vorderwand sowie an der Rückwand schnell durchführbar ist.It is also in accordance with the invention that the handle is part of a carrier element which is fastened to the inside of the front wall or / or to the inside of the back wall. Within the scope of the bag according to the invention, the invention includes the carrier element being designed as a slip. It is particularly advantageous that this carrier element is inexpensive to manufacture, and at the same time an inside fastening of the carrier element to the front wall and to the rear wall can be carried out quickly.

Ferner kann die Erfindung vorsehen, dass die Befestigung stoffschlüssig an beiden Wänden erfolgt, wobei insbesondere ein Heißleimverbindung oder ein Kaltleimverbindung vorliegt. Der Heißleim kann zumindest einen der folgenden Inhaltsstoffe umfassen: Basispolymer, Harz, Stabilisatoren, Wachs, Nukleierungsmittel. Als Basispolymer ist beispielsweise PA (Polyamide), PE (Polyethylen), APAO (Amorphe Polyalphaolefine), EVAC (Ethylenvinylacetat-Copolymere), TPE-E (Thermoplastische Polyester-Elastomere), TPE-U (Thermoplastische Polyuretan-Elastomere), TPE-A (Thermoplastische Copolyamid-Elastomere). Als Harz können Kolophonium und/oder Terpene und/oder Kohlenwasserstoffharze zum Einsatz kommen. Erfindungsgemäß sind für Stabilisatoren beispielsweise Antioxidantien und/oder Metalldesaktivatoren und/oder Lichtschutzmittel einsetzbar. Hinsichtlich der Nukleierungsmittel ist es erfindungsgemäß denkbar, diese zur Modifizierung teilkristalliner Kunststoffe zuzugeben. Diese sorgen dafür, dass die Kristallbildung bei höherer Temperatur eintritt. Über die Verwendung des Heißklebers ergibt sich der Vorteil, dass verschiedenste Materialien verklebt werden können. Zudem können Unebenheiten von zu verklebenden Oberflächen leicht ausgeglichen werden.Furthermore, the invention can provide that the attachment takes place cohesively on both walls, in particular a hot glue connection or a cold glue connection being present. The hot melt can comprise at least one of the following ingredients: base polymer, resin, stabilizers, wax, nucleating agent. The base polymer is, for example, PA (polyamides), PE (polyethylene), APAO (amorphous polyalphaolefins), EVAC (ethylene-vinyl acetate copolymers), TPE-E (thermoplastic polyester elastomers), TPE-U (thermoplastic polyurethane elastomers), TPE-A (Thermoplastic copolyamide elastomers). Rosin and / or terpenes and / or hydrocarbon resins can be used as the resin. According to the invention, antioxidants and / or metal deactivators and / or light stabilizers, for example, can be used for stabilizers. With regard to the nucleating agents, it is conceivable according to the invention to add these for modifying partially crystalline plastics. These ensure that the Crystal formation occurs at a higher temperature. Using the hot glue has the advantage that a wide variety of materials can be glued. In addition, unevenness of the surfaces to be glued can be easily compensated.

Ein Vorteil beim Einsatz eines Kaltleims ist, dass sehr hohe Maschinengeschwindigkeiten bei der Kaltklebetechnik erzielt werden können. Zudem lässt sich der Kaltleim relativ einfach auftragen.One advantage of using cold glue is that very high machine speeds can be achieved with cold glue technology. In addition, the cold glue is relatively easy to apply.

Der erfindungsgemäße Beutel kann in einer möglichen Ausführungsform ein Trägerelement aufweisen, das derart ausgestanzt oder gelasert oder perforiert ist, dass der Griff aus dem Trägerelement erfindungsgemäss herausfaltbar ist. Ein wesentlicher Vorteil dieser Ausführungsform ist, dass bei der Herstellung der Tragegriffpaare kein Abfall entsteht. In der Ruhestellung ist der Griff vollständig im Trägerelement integriert und bildet mehr oder weniger eine Einheit. Vorteilhafterweise weist das Trägerelement hierbei eine flache Form auf, die wenig Volumen innerhalb des Beutels benötigt.In one possible embodiment, the bag according to the invention can have a carrier element which is punched out or lasered or perforated such that the handle can be folded out of the carrier element according to the invention. A major advantage of this embodiment is that there is no waste during the manufacture of the pairs of handles. In the rest position, the handle is fully integrated in the carrier element and more or less forms a unit. The carrier element advantageously has a flat shape which requires little volume within the bag.

Ebenfalls ist es erfindungsgemäß möglich, dass das Trägerelement bündig zum Rand der Vorderwand und/oder der Rückwand angeordnet ist, wobei der Rand gegenüberliegend zum Boden angeordnet ist. Es hat sich gezeigt, dass durch eine derartige Maßnahme die Stapelung der Beutel bezüglich der Kompaktheit verbessert werden kann. Beispielsweise ist es denkbar, dass das Trägerelement rechteckförmig und/oder quadratisch ausgeführt ist. Zudem kann es in eigenen Anwendungsfällen, bezogen auf den Beutel, Sinn machen, dass das Trägerelement eine Materialstärke aufweist, die größer ist als die der Vorderwand und/oder der Rückwand. Alternativ und/oder zusätzlich schließt die Erfindung mit ein, dass das Trägerelement aus einem materialverstärkten und/oder gewebeverstärkten Papier und/oder Gewebe und/oder Vlies oder aus einem Kunststoff ausgeführt ist. Erfindungsgemäß kann das Trägerelement ein Gewicht von ungefähr 200 g/m2 bis 300 g/m2 aufweisen. Erfindungsgemäß kann das Trägerelement ein Gewicht von weniger als 200 g/m2 aufweisen, bevorzugt ein Gewicht von weniger als 100 g/m2 aufweisen, besonders bevorzugt ein Gewicht von weniger als 65 g/m2 aufweisen. Ein weiterer Vorteil ist, dass das Trägerelement als Randverstärkung, die außenseitig nicht sichtbar ist, für den Beutel dient. Ebenfalls ist es denkbar, dass das Trägerelement beabstandet vom Rand der Vorderwand und/oder Rückwand angeordnet ist.It is also possible according to the invention that the carrier element is arranged flush with the edge of the front wall and / or the rear wall, the edge being arranged opposite the floor. It has been shown that the stacking of the bags can be improved in terms of compactness by such a measure. For example, it is conceivable that the carrier element is rectangular and / or square. In addition, it can make sense in individual applications, based on the bag, that the carrier element has a material thickness that is greater than that of the front wall and / or the rear wall. Alternatively and / or additionally, the invention includes that the carrier element is made from a material-reinforced and / or fabric-reinforced paper and / or fabric and / or non-woven or from a plastic. According to the invention, the carrier element can have a weight of approximately 200 g / m 2 to 300 g / m 2 . According to the invention, the carrier element can have a weight of less than 200 g / m 2 , preferably have a weight of less than 100 g / m 2 , particularly preferably have a weight of less than 65 g / m 2 . Another advantage is that the carrier element serves as an edge reinforcement for the bag, which is not visible on the outside. It is also conceivable that the carrier element is arranged at a distance from the edge of the front wall and / or rear wall.

Die Faltlinie kann auch am Rand der Vorderwand und/oder der Rückwand angeordnet sein. Auch hier versteht die vorliegende Erfindung darunter, dass die Faltlinie des Tragegriffpaares im Füllraum sich befindet. Die Faltlinie kann auch erst bei einem Überführen der Tragegriffpaare aus der Ruhestellung in die Gebrauchsstellung als Knicklinie entstehen. Die Faltlinie kann auch bereits während des Herstellungsprozesses des Beutels entstehen oder vorgebrochen sein, zum Beispiel wenn die Trägerelemente mit den Tragegriffpaaren entstehen, bevor das Trägerelement auf die Materialbahn gebracht wird.The fold line can also be arranged on the edge of the front wall and / or the rear wall. Here, too, the present invention understands that the fold line of the pair of handles is in the filling space. The fold line can also only emerge as a crease line when the pairs of handles are transferred from the rest position into the use position. The fold line can also arise during the manufacturing process of the bag or be broken, for example if the carrier elements with the pairs of handles are created before the carrier element is brought onto the material web.

Ferner umfasst ein erfindungsgemäßer Beutel das Merkmal, dass am Rand der Vorderwand oder der Rückwand eine Öffnungshilfe ausgeführt ist, insbesondere dass die Öffnungshilfe als Ausnehmung ausgebildet ist. Um den zusammengefalteten Beutel zu nutzen, kann der Benutzer die Öffnungshilfe verwenden, um einfacher den Beutel in Richtung Vorderwand und/oder Rückwand zu drücken, damit beispielsweise Gegenstände in den Füllraum gelegt werden können. Die Geometrie der Öffnungshilfe kann halbkreisförmig sein, damit beispielsweise ein Daumen oder Finger zielgerichteter durch diese Öffnungshilfe geführt werden kann. Weitere geometrische Formgestaltungen der Öffnungshilfe sind denkbar.Furthermore, a bag according to the invention comprises the feature that an opening aid is implemented on the edge of the front wall or the rear wall, in particular that the opening aid is designed as a recess. In order to use the folded bag, the user can use the opening aid to press the bag more easily in the direction of the front wall and / or rear wall so that, for example, objects can be placed in the filling space. The geometry of the opening aid can be semicircular so that, for example, a thumb or finger can be guided through this opening aid in a more targeted manner. Further geometrical shapes of the opening aid are conceivable.

Zudem ist es denkbar, dass der Rand perforiert und/oder ausgefilzt und/oder ausgefasert ist. Der umlaufende Rand des Beutels ist somit stumpf ausgeführt, ohne dass ein Schneidrisiko für den Benutzer am Rand des Beutels besteht. Vorteilhafterweise ist der Beutel aus einem Papiermaterial ausgebildet und kann in Form eines flexiblen Beutels unterschiedlichst eingesetzt werden. Der speziell ausgeführte Rand kann erfindungsgemäß mikroskopisch filzartig ausgeführt sein, wodurch ein relativ "weicher" Rand entsteht. Erfindungsgemäß kann der Rand perforationsartig ausgebildet sein, das bedeutet, dass beispielsweise über einen Abreißvorgang dieser Rand am Beutel entsteht bzw. entstanden ist.It is also conceivable that the edge is perforated and / or felted out and / or frayed. The peripheral edge of the bag is thus made blunt, without there being a risk of cutting for the user at the edge of the bag. The bag is advantageously formed from a paper material and can be used in a wide variety of ways in the form of a flexible bag. According to the invention, the specially designed edge can be microscopically felt-like, which creates a relatively "soft" edge. According to the invention, the edge can be designed like a perforation, which means that this edge is or has been created on the bag, for example, by a tear-off process.

Der Griff des erfindungsgemäßen Beutels kann die Form eines Werbeträgers aufweisen, insbesondere kann der Griff M-förmig ausgebildet sein. Dieser Werbeträger kann zum Beispiel auf den Inhalt des Beutels hinweisen oder einen Markenhinweis dem Benutzer liefern.The handle of the bag according to the invention can have the shape of an advertising medium, in particular the handle can be M-shaped. This advertising medium can, for example, refer to the content of the bag or provide the user with a brand reference.

Die Erfindung schließt mit ein, dass die Vorderwand und/oder die Rückwand ein Sichtfenster oder ein Sichtstreifen oder ein Netz aufweisen. Das Sichtfenster ist vorzugsweise aus einem transparenten Material ausgeführt. Das transparente Material ermöglicht, dass der Benutzer zumindest teilweise in die Kavität des Beutels Einsicht nehmen kann.The invention includes that the front wall and / or the rear wall have a viewing window or a viewing strip or a net. The viewing window is preferably made of a transparent material. The transparent material enables the user to at least partially inspect the cavity of the bag.

Zusätzlich kann erfindungsgemäß vorgesehen sein, dass zwischen der Vorderwand und der Rückwand zumindest eine Seitenfaltung verläuft. Die Seitenfaltung kann eine oder mehrere Seitenfalten aufweisen. Vorteilhafterweise erstreckt sich die Seitenfaltung von der Öffnung bzw. vom Rand des Beutels ausgehend in Richtung des Bodens. Die Funktion der Seitenfaltung ist, dass der Füllraum bzw. die Kavität innerhalb des Beutels zuverlässig vergrößert werden kann, indem die Vorderwand und die Rückwand voneinander vom Benutzer weggedrückt werden. Im nicht zu benutzenden Zustand des Beutels können beide Wände aufeinander liegen, wobei die Seitenfalten zwischen diesen beiden Wänden liegen können.In addition, it can be provided according to the invention that at least one side fold runs between the front wall and the rear wall. The gusset may have one or more gussets. The side fold advantageously extends from the opening or from the edge of the bag in the direction of the bottom. The function of the side fold is that the filling space or the cavity within the bag can be reliably enlarged by pushing the front wall and the rear wall away from one another by the user. When the pouch is not in use, both walls can lie on top of one another, the side folds being able to lie between these two walls.

Der Boden des erfindungsgemäßen Beutels kann als Kreuzboden oder als Blockboden oder als Flach- und Seitenfaltenboden oder als Falzboden oder als Pinchboden ausgeführt sein. Ein Vorteil in der Verwendung eines Kreuzbodens ist, dass viel Fläche an der Vorderwand sowie an der Rückwand des Beutels geschaffen werden kann, wodurch das Füllvolumen vergrößert werden kann. Zudem bietet der Beutel an den Außenwänden ein größeres "Gesicht", um zum Beispiel als Informationsträger und/oder Werbeträger zu dienen. Ein besonderer Vorteil des Blockbodens ist hierbei, dass das Standvermögen des Beutels durch einen derartigen Boden verbessert ist, insbesondere wenn der Beutel Seitenfalten aufweist.The bottom of the bag according to the invention can be designed as a cross bottom or as a block bottom or as a flat and gusseted bottom or as a folded bottom or as a pinch bottom. An advantage of using a cross bottom is that a lot of space can be created on the front wall and on the back wall of the bag, which can increase the filling volume. In addition, the bag has a larger "face" on the outer walls, for example to serve as an information carrier and / or advertising medium. A particular advantage of the block bottom is that the stability of the bag is improved by such a bottom, especially if the bag has gussets.

Zudem wird die oben genannte Aufgabe durch ein Verfahren zur Herstellung mindestens eines Beutels gelöst, wobei der Beutel mit einer Vorderwand und einer zur Vorderwand parallel angeordneten Rückwand ausgeführt ist, wobei zudem der Beutel einen in die Ebene der Wände faltbaren Boden aufweist, so dass sich ein einseitig offener Füllraum ergibt. Ferner weist der Beutel ein Tragegriffpaar auf, das an der Vorderwand und an der Rückwand befestigt ist, wobei das erfindungsgemäße Verfahren folgende Schritte aufweist:

  1. a) Befestigen von zwei zueinander beabstandeten Trägerelementen an einer sich translatorisch bewegenden Materialbahn, wobei an dem Trägerelement zumindest ein herausfaltbarer Griff integriert ist,
  2. b) Schlauchbildung der Materialbahn, so dass die Materialbahn einen Schlauch bildet und die Trägerelemente übereinanderliegen,
  3. c) Vereinzelung der Materialbahn, so dass einzelne Schlauchabschnitte mit zumindest zwei übereinanderliegenden Trägerelementen entstehen, die innerhalb des Schlauches liegen,
  4. d) Faltung des Schlauches, so dass zumindest ein Boden entsteht, wobei weitere Details Anspruch 12 zu entnehmen sind.
In addition, the above-mentioned object is achieved by a method for producing at least one bag, the bag being designed with a front wall and a rear wall arranged parallel to the front wall, the bag also having a bottom which can be folded into the plane of the walls, so that a filling space open on one side results. Furthermore, the bag has a pair of handles which are fastened to the front wall and to the rear wall, the method according to the invention comprising the following steps:
  1. a) attaching two spaced-apart support elements to a translationally moving material web, at least one fold-out handle being integrated on the support element,
  2. b) hose formation of the material web so that the material web forms a hose and the carrier elements lie one above the other,
  3. c) separation of the material web so that individual tube sections with at least two superimposed support elements are formed which lie within the tube,
  4. d) folding the hose so that at least one base is formed, further details being set out in claim 12.

Es entsteht ein Beutel, der die Vorteile aufweist, die bereits hinsichtlich des erfindungsgemäßen Beutels, bezogen auf den unabhängigen Patentanspruch 1, genannt wurden. Zudem zeichnet sich das erfindungsgemäße Verfahren durch eine hohe Herstellungseffizienz bezogen auf die Stückzahl der Beutel aus, die produzierbar sind. Die Materialbahn kann auch ein einzelner Materialbogen, insbesondere Papierbogen sein, der ein Anfang und ein Ende aufweist.The result is a bag which has the advantages which have already been mentioned with regard to the bag according to the invention, based on independent claim 1. In addition, the method according to the invention is characterized by a high manufacturing efficiency based on the number of bags that can be produced. The material web can also be a single sheet of material, in particular paper sheet, which has a beginning and an end.

Vorteilhafterweise ist es denkbar, dass der Schritt d) vor dem Schritt c) erfolgt, das bedeutet, dass vor einer Vereinzelung der Materialbahn bereits eine Faltung des Bodens erfolgen kann. Dieses ist beispielsweise denkbar, wenn der Boden als ein Blockbodenbeutel oder als Kreuzbodenbeutel gefaltet wird.Advantageously, it is conceivable that step d) takes place before step c), which means that the base can already be folded before a separation of the material web. This is conceivable, for example, if the bottom is folded as a block bottom bag or as a cross bottom bag.

Vorteilhafterweise kann vor dem Schritt b) eine Öffnungshilfe am Randbereich eines der beiden Trägerelemente eingebracht werden, insbesondere die Öffnungshilfe als eine Materialausnehmung im Trägerelement und in der Materialbahn ausgeführt werden. Somit wird erreicht, dass lediglich eine der beiden Beutelwände mit einer Öffnungshilfe ausgestattet ist.Before step b), an opening aid can advantageously be introduced at the edge region of one of the two carrier elements, in particular the opening aid can be designed as a material recess in the carrier element and in the material web. It is thus achieved that only one of the two bag walls is equipped with an opening aid.

Des Weiteren kann das erfindungsgemäße Verfahren derart ausgeführt sein, dass das Trägerelement zwei herausfaltbare Griffe aufweist, die im Schritt a) in Richtung der Materialbahnbewegung hintereinander angeordnet werden. Hierdurch kann die Effizienz zur Herstellung der Beutel verdoppelt werden. Zudem ist es denkbar, dass vor dem Schritt b) eine Öffnungshilfe mittig an einem der beiden Trägerelemente eingebracht wird, insbesondere dass die Öffnungshilfe als eine Materialausnehmung im Trägerelement und in der Materialbahn ausgeführt wird. Hierbei kann eine Lochstanze oder eine Kreislochstanze diese Materialausnehmung bewirken. Die Geometrie der Ausnehmung kann z. B. wie folgt sein: kreisförmig, ovalförmig, quadratisch, eckig, rechteckig, vieleckig. Alternativ und/oder zusätzlich kann das Verfahren erfindungsgemäß derart ausgeführt sein, dass die übereinanderliegenden Trägerelemente gemäß Schritt b) bei der Aufbringung auf die Materialbahn nach Schritt a) senkrecht zur Materialbahnbewegungsrichtung zueinander ausgerichtet und angeordnet werden.Furthermore, the method according to the invention can be carried out in such a way that the carrier element has two fold-out handles which are arranged one behind the other in step a) in the direction of the material web movement. As a result, the efficiency for producing the bags can be doubled. In addition, it is conceivable that an opening aid is introduced centrally on one of the two carrier elements before step b), in particular that the opening aid is designed as a material recess in the carrier element and in the material web. A hole punch or a circular hole punch can effect this material recess. The geometry of the recess can, for. B. as follows be: circular, oval, square, angular, rectangular, polygonal. Alternatively and / or additionally, the method can be carried out according to the invention in such a way that the support elements lying one above the other are aligned and arranged relative to one another perpendicularly to the direction of material movement in step b) when applied to the material web after step a).

Im Falle eines Trägerelementes mit zwei herausfaltbaren Griffen ist es von Vorteil, wenn im Schritt d) zwei zueinander gegenüberliegende Böden gefaltet werden und im Anschluss der sich gebildete Schlauch mit Böden und Trägerelementen mittig durchtrennt wird, so dass zwei Beutel entstehen. Somit kann die Effizienz verdoppelt werden, da in einem Verfahrenszyklus gleichzeitig zwei Beutel entstehen.In the case of a carrier element with two fold-out handles, it is advantageous if in step d) two bottoms lying opposite one another are folded and then the tube formed is trimmed in the center with bottoms and carrier elements, so that two bags are created. Efficiency can thus be doubled, since two bags are created simultaneously in one process cycle.

In einer weiteren Ausgestaltung der Erfindung kann es Sinn machen, dass nach dem Schritt a) oder vor dem Schritt a) eine Perforationslinie senkrecht zur Materialbahnbewegungsrichtung auf der Materialbahn aufgebracht wird. Insbesondere kann eine Perforationslinie Sinn machen, wenn der Boden als Flach- und Seitenfaltenboden gefaltet wird.In a further embodiment of the invention, it can make sense that after step a) or before step a), a perforation line is applied to the material web perpendicular to the direction of material web movement. In particular, a perforation line can make sense if the bottom is folded as a flat and gusseted bottom.

Erfindungsgemäß kann vor dem Schritt a) das Trägerelement derart gestanzt oder perforiert oder gelasert wird, dass zumindest ein aus dem Trägerelement herausfaltbarer Griff entsteht. Ebenfalls es ist denkbar, dass in einem Trägerelement zwei herausfaltbare Griffe entstehen. Zudem ist zu beachten, dass kein Materialabfall entsteht, welches aus Umweltgesichtspunkten vorteilhaft ist.According to the invention, the carrier element can be punched or perforated or lasered before step a) in such a way that at least one handle that can be folded out of the carrier element is produced. It is also conceivable that two fold-out handles are created in a carrier element. It should also be noted that there is no material waste, which is advantageous from an environmental point of view.

Vorteilhafterweise ist die Transportrichtung der Materialbahn oder des Schlauches oder des Schlauchabschnittes im Schritt a) bis Schritt b) oder bis Schritt c) senkrecht zur Transportrichtung für den Schritt d) und/oder für den Schritt zum Durchtrennen des Schlauches, das zwei gegenüberliegende Böden aufweist. Mitumfasst ist, dass die senkrecht zueinander stehenden Transportrichtungen auch übereinander liegen können.Advantageously, the transport direction of the material web or the hose or the hose section in step a) to step b) or to step c) is perpendicular to the transport direction for step d) and / or for the step for severing the hose, which has two opposite floors. It also includes that the transport directions that are perpendicular to one another can also lie one above the other.

Besonders vorteilhaft ist, dass die Transportrichtung der Materialbahn oder des Schlauches oder des Schlauchabschnittes im Schritt d) quer zur Beutellängserstreckung ist, wodurch sich die Effizienz bei der Bodenfaltung erhöhen lässt.It is particularly advantageous that the direction of transport of the material web or the hose or the hose section in step d) is transverse to the longitudinal extension of the bag, as a result of which the efficiency in the bottom folding can be increased.

Zudem kann ein Maschinensystem vorgesehen sein zur Herstellung eines Beutels mit einer Vorderwand und einer zur Vorderwand parallel angeordneten Rückwand, einem in die Ebene der Wände faltbaren Boden, so dass ein einseitig offener Füllraum sich ergibt, und einem Tragegriffpaar, das an der Vorderwand und der Rückwand innerhalb des Füllraumes befestigt ist. Hierbei weist das Maschinensystem folgende Aggregate bzw. Maschinenkomponenten auf:

  1. a) Vorrichtung zur Aufbringung mindestens eines Tragegriffpaares auf eine Materialbahn,
  2. b) Schlauchbildungsvorrichtung, mit der die Materialbahn in die Form eines Schlauches bringbar ist,
  3. c) Vereinzelvorrichtung, mit der die schlauchförmige Materialbahn in Schlauchabschnitte derart trennbar ist, dass das Tragegriffpaar verdeckt innerhalb des Schlauchabschnittes verbleibt,
  4. d) Bodenleger, mit dem zumindest ein Boden am Schlauch faltbar ist.
In addition, a machine system can be provided for producing a bag with a front wall and a rear wall arranged parallel to the front wall, a bottom which can be folded into the plane of the walls, so that a filling space is open on one side, and a pair of handles which are on the front wall and the rear wall is fixed within the filling space. Here, the machine system has the following units or machine components:
  1. a) device for applying at least one pair of handles to a material web,
  2. b) hose forming device with which the material web can be brought into the form of a hose,
  3. c) separating device with which the tubular material web can be separated into tubular sections in such a way that the pair of carrying handles remain concealed within the tubular section,
  4. d) Floor layer, with which at least one floor can be folded on the hose.

Vorteilhafterweise kann gemäß a) die Vorrichtung geeignet sein zwei Tragegriffpaare auf der Materialbahn aufzubringen, wobei gemäß d) der Bodenleger geeignet sein kann, zwei zueinander gegenüberliegende Böden zu falten, wobei eine Trennvorrichtung vorgesehen sein kann, mit der der gebildete Schlauchabschnitt mit Böden und Trägerelementen mittig durchtrennbar ist, so dass zwei Beutel entstehen können. Beispielsweise kann die Trennvorrichtung einen Zackenschnitten vornehmen, so dass ein stumpfer nicht schneidender Rand am Beutel entsteht. Ebenfalls kann vorgesehen sein, dass der Schnitt derart durch die Trennvorrichtung durchgeführt wird, dass ein perforierter Rand oder ausgefilzter Rand oder ein ausgefaserter Rand entsteht, wodurch ebenfalls die Verletzungsgefahr am Rand gemindert wird. Der Bodenleger kann als Bodenbildungseinheit ausgeführt sein, die vorteilhafterweise auch in einem separaten Aggregat des Maschinensystems integriert sein kann. Alternativ ist ein glatter Rand denkbar, der zum Beispiel bei einem leichten Beutelmaterial zum Einsatz kommen kann, ohne dass die Gefahr besteht, dass eine Verletzung am Rand für den Benutzer sich ergibt.Advantageously, according to a) the device can be suitable to apply two pairs of handles on the material web, whereby according to d) the floor layer can be suitable to fold two floors lying opposite one another, wherein a separating device can be provided with which the tube section formed with floors and support elements is centered is severable so that two bags can be created. For example, the separating device can make a serrated cut so that a blunt, non-cutting edge is created on the bag. It can also be provided that the cut is carried out by the separating device in such a way that a perforated edge or felted edge or a frayed edge is produced, which likewise reduces the risk of injury at the edge. The floor layer can be designed as a floor formation unit, which can advantageously also be integrated in a separate unit of the machine system. Alternatively, a smooth edge is conceivable, which can be used, for example, in the case of a light bag material, without there being any risk of the user being injured at the edge.

Des Weiteren kann das Maschinensystem derart weiterentwickelt sein, dass die Vorrichtung gemäß a) geeignet ist, eine Öffnungshilfe an einem der beiden Trägerelemente einzubringen, insbesondere dass die Öffnungshilfe als eine Materialausnehmung im Trägerelement und in der Materialbahn ausgeführt ist. Solange die Materialbahn noch nicht als Schlauch gebildet ist, ist es besonders vorteilhaft, einen der beiden Trägerelemente mit der Öffnungshilfe zu versehen. Ebenfalls kann es alternativ denkbar sein, im Schlauchbildungsaggregat gemäß b) oder in den Aggregaten zur Vereinzelung der Materialbahn oder im Bodenleger die Funktion zu integrieren, eine Öffnungshilfe im Trägerelement einzubringen.Furthermore, the machine system can be further developed such that the device according to a) is suitable for introducing an opening aid on one of the two carrier elements, in particular that the opening aid as one Material recess is carried out in the carrier element and in the material web. As long as the material web has not yet been formed as a tube, it is particularly advantageous to provide one of the two carrier elements with the opening aid. Alternatively, it may also be conceivable to integrate the function of introducing an opening aid into the carrier element in the hose formation unit according to b) or in the units for separating the material web or in the floor layer.

Das Maschinensystem schließt die Möglichkeit mit ein, dass die Vorrichtung gemäß a) sowie die Schlauchbildungsvorrichtung und die Vereinzelungsvorrichtung und der Bodenleger innerhalb eines Aggregates integriert sind. Dieses ist insbesondere dann realisierbar, wenn das Maschinensystem ohne Trennvorrichtung arbeitet, bei dem in der Vorrichtung zur Aufbringung eines Tragegriffpaares auf eine Materialbahn ein Trägerelement verwendet wird, in dem lediglich ein herausfaltbarer Griff integriert ist.The machine system includes the possibility that the device according to a) as well as the hose forming device and the separating device and the floor layer are integrated within one unit. This is particularly feasible if the machine system works without a separating device, in which a carrier element is used in the device for applying a pair of handles to a material web, in which only a fold-out handle is integrated.

Alternativ ist es denkbar, dass die Vorrichtung gemäß a) sowie die Schlauchbildungsvorrichtung und die Vereinzelungsvorrichtung in einem ersten Aggregat integriert sind und der Bodenleger sowie die Trennvorrichtung in einem zweiten Aggregat integriert sind. Eine derartige Anordnung kann von Vorteil sein, wenn gemäß der Vorrichtung zur Aufbringung eines Tragegriffpaares auf eine Materialbahn ein Trägerelement verwendet wird, in dem zwei herausfaltbare Griffe integriert sind, die in Richtung der Materialbahnbewegung hintereinander angeordnet sind.Alternatively, it is conceivable that the device according to a) and the hose forming device and the separating device are integrated in a first unit and the floor layer and the separating device are integrated in a second unit. Such an arrangement can be advantageous if, according to the device for applying a pair of carrying handles to a material web, a carrier element is used in which two fold-out handles are integrated, which are arranged one behind the other in the direction of the material web movement.

Mit dem genannten Maschinensystem sind sämtliche Verfahrensschritte realisierbar, die in den Verfahrensansprüchen beansprucht sind. Das Maschinensystem kann des Weiteren Beutel herstellen, die die Merkmale beanspruchen können, die in den Patentansprüchen 1 bis 16 beschrieben sind.With the machine system mentioned, all process steps can be implemented, which are claimed in the process claims.
