Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines aus einer Polyäthylen/Papier-Polyäthylen-Verbundfolie bestehenden Schlauchbeutels, bei dem die Verbundfolie getaktet von einer Vorratsrolle abgezogen und in einer Formschulter zu einem Schlauch geformt und als solcher zu einer Siegelstation geführt wird, in der die gefüllten Beutel durch Setzen einer Querversiegelung gebildet werden.The invention relates to a method for producing a tubular bag consisting of a polyethylene / paper-polyethylene composite film, in which the composite film is removed in a clocked manner from a supply roll and shaped into a tube in a forming shoulder and as such is guided to a sealing station in which the filled Bags are formed by placing a cross seal.
Schlauchbeutel, die aus einer Polyäthylen/Papier-Poly äthylen-Verbundfolie geformt sind, finden in vielfältiger Weise Verwendung.Tubular bags made of a polyethylene / paper poly Ethylene composite film are shaped, are used in many ways.
Es ist erwünscht, derartige Schlauchbeutel aus einer Polyäthylen/Papier-Polyäthylen-Verbundfolie mit einer Griffausnehmung zu versehen, die das Transportieren erleichtert.It is desirable to provide such tubular bags made of a polyethylene / paper-polyethylene composite film with a handle recess, which facilitates transportation.
Die bekannten Schlauchbeutel aus einer Polyäthylen/Papier-Polyäthylen-Verbundfolie sind jedoch nicht ausreichend stabil, um das Einbringen einer Griffausnehmung zu erlauben; eine derartige Griffausnehmung würde alsbald einreißen.However, the known tubular bags made of a polyethylene / paper-polyethylene composite film are not sufficiently stable to allow the insertion of a handle recess; such a recess would soon tear.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen eines aus einer Polyäthylen/Papier-Polyäthylen-Verbundfolie zu schaffen, der mit einer Griffausnehmung versehen ist.The invention has for its object to provide a method for producing a from a polyethylene / paper-polyethylene composite film, which is provided with a handle recess.
Erfindungsgemäß wird diese Aufgabe gelöst durch Aufbringen eines beidseitig mit Polyäthylen beschichteten Polypropylengewebes auf die Verbundfolie vor dem Formen zu einem Schlauch, Anheften des Polypropylengewebes auf die Folie vor deren Formung zu einem Schlauch, beidseitiges Verschweißen des beidseitig mit Polyäthylen beschichteten Polypropylengewebes mit der Verbundfolie nach dem Formen zu einem Schlauch, und Stanzen einer Griffausnehmung durch die Verbundfolie und das Polypropylengewebe.According to the invention, this object is achieved by applying a polypropylene fabric coated on both sides with polyethylene to the composite film before forming it into a tube, attaching the polypropylene fabric to the film before forming it into a tube, welding the polypropylene fabric coated on both sides with polyethylene to the composite film after molding to a tube, and punching a handle recess through the composite film and the polypropylene fabric.
Weiter wird vorgeschlagen, daß das Polypropylengewebe von einer Endlosrolle abgezogen und nach Aufbringen auf die Verbundfolie abgeschnitten wird.It is further proposed that the polypropylene fabric be pulled off an endless roll and cut off after application to the composite film.
Eine bevorzugte Ausführungsform zeichnet sich dadurch aus, daß das Polypropylengewebe durch thermische Einwirkung an die Verbundfolie angeheftet wird.A preferred embodiment is characterized in that the polypropylene fabric is attached to the composite film by thermal action.
Weiter wird vorgeschlagen, daß das Verschweißen des Polypropylengewebes gleichzeitig mit dem Verschweißen der Randsiegelnaht erfolgt.It is also proposed that the polypropylene fabric be welded simultaneously with the welding of the edge sealing seam.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:
- Fig. 1 eine schematische Darstellung des Herstellungsverfahrens,
- Fig. 2 eine Detaildarstellung der Siegelbacke,
- Fig. 3 einen Schlauchbeutel bei Verlassen der Siegelstation, und
- Fig. 4 den Schlauchbeutel nach der Stanzung der Profilsiegelung und der Griffstanzung.
- 1 is a schematic representation of the manufacturing process,
- 2 shows a detailed illustration of the sealing jaw,
- Fig. 3 shows a tubular bag when leaving the sealing station, and
- Fig. 4 the tubular bag after punching the profile seal and the handle punch.
Zur Herstellung des Schlauchbeutels wird eine Polyäthylen/Papier-Polyäthylen-Verbundfolie 10 von einer Vorratsrolle 12 getaktet abgezogen. Diese Verbundfolie 10 wird - in bekannter Weise - in einer Formschulter 14 zu einem Beutel geformt. Nach Verschweißen der längs der Erstreckung der Folie verlaufenden Randsiegelnaht wird der Beutel durch die Formschulter 14 hindurch gefüllt und sodann in einer Siegelstation 16 mit einer Quernaht versehen, durch die die einzelnen Beutel definiert werden.To produce the tubular bag, a polyethylene / paper-polyethylene composite film 10 is removed from a
Um den Schlauchbeutel mit einer Griffausnehmung versehen zu können, wird auf die von der Vorratsrolle 12 abgezogene Verbundfolie ein von einer weiteren Vorratsrolle 20 abgezogenes, beidseitig mit Polyäthylen beschichtetes Polypropylengewebe auf die Verbundfolie 10 aufgelegt und durch eine Siegelbacke 24 auf diese aufgeheftet. Das von der Rolle 20 abgezogene Gewebe wird durch eine geeignet ausgebildete Einrichtung, die in der Zeichnung lediglich schematisch durch eine Schere angedeutet wird, abgeschnitten.In order to be able to provide the tubular bag with a handle recess, a polypropylene fabric pulled off from a
Die derart mit einer Griffverstärkung 30 aus einem Polypropylengewebe versehene Folie wird in üblicher Weise durch die Formschulter 14 zu der Siegelstation 16 geführt.The film provided with a
Durch geeignete, zeichnerisch im einzelnen nicht dargestellte Mittel wird das beidseitig mit Polyäthylen beschichtete Polypropylengewebe mit den an diesen anliegenden Flächen der Polyäthylen/Papier-Polyäthylen-Verbundfolie verschweißt, wobei dieses Verschweißen einfach zu bewerkstelligen ist, da bei diesem Vorgang lediglich die Polyäthylenbeschichtung des Polypropylengewebes mit der Polyäthylenbeschichtung der Verbundfolie miteinander zu verschweißen sind.By means of suitable means not shown in the drawing, the polypropylene fabric coated on both sides with polyethylene is welded to the surfaces of the polyethylene / paper-polyethylene composite film adjacent to these, this welding being easy to accomplish, since in this process only the polyethylene coating of the polypropylene fabric is used the polyethylene coating of the composite film are to be welded together.
Anschließend (oder aber auch gleichzeitig mit dem Verschweißen) wird eine Griffausnehmung 28 durch die beiden Lagen der Verbundfolie und durch das Polypropylengewebe gestanzt und eine Profilsiegelung vorgenommen.Subsequently (or also simultaneously with the welding), a handle recess 28 is punched through the two layers of the composite film and through the polypropylene fabric and a profile seal is carried out.
Bei einem Vorgehen nach der Erfindung kann ein Schlauchbeutel aus einer Polyäthylen/Papier-Polyäthylen-Verbundfolie geschaffen werden, der mit einer Griffausnehmung versehen ist, die das Transportieren des Beutels erleichtert. Dabei bildet das Polypropylengewebe eine Griffverstärkung, so daß ein Ausreißen des Beutels im Griffbereich nicht zu befürchten ist.In a procedure according to the invention, a tubular bag made of a polyethylene / paper-polyethylene composite film can be created, which with a Handle recess is provided, which facilitates the transport of the bag. The polypropylene fabric forms a grip reinforcement so that there is no fear of the bag tearing out in the grip area.
Das Verschweißen des Polypropylengewebes kann gleichzeitig oder aber anschließend an das Schweißen der Randsiegelnaht erfolgen. Die Fertigstellung des Beutels kann in der Schlauchbeutelmaschine oder aber in einer separaten Maschine erfolgen.The polypropylene fabric can be welded simultaneously or after the edge seal seam has been welded. The bag can be finished in the tubular bag machine or in a separate machine.
