Abstract

Disclosed is a process for manufacturing a bag, wherein an edge region of a double-layer starting material is welded together by means of a seam, said process being characterized in that a sealing seam is created in the edge region, and a separating seam is introduced in the area of the sealing seam, parallel to the sealing seam.

Description

B E S C H R E I B U N G  DESCRIPTION
In einer Siegelnaht liegende Trennnaht bei der Herstellung von Beuteln Sealing seam in a sealed seam during the production of bags
Die Erfindung betrifft ein Verfahren zur Herstellung von Beuteln. The invention relates to a method for producing bags.
Aus der EP 2 361 842 B1 ist es bekannt, einen Beutel aus Kunststoffmaterial mit einer Griffleiste herzustellen. Damit die Dichtheit des Beutels in seinen Randbereichen gewährleistet ist, erfolgt im Randbereich sowohl das Einbringen einer Trennnaht als auch das Einbringen einer gegenüber der Trennnaht breiteren Siegelnaht. Dadurch soll sichergestellt werden, dass es in Folge der Handhabung des fertigen Beutels nach dem Befüllen mit einem Füllgut nicht zu einem Aufreißen an der Seitenkante kommt, falls nur eine Naht (entweder Trennnaht oder Siegelnaht) dort vorhanden ist. From EP 2 361 842 B1 it is known to produce a bag made of plastic material with a handle strip. Thus, the tightness of the bag is ensured in its edge regions, carried out in the edge region both the introduction of a cutting seam and the introduction of a relation to the separating seam wider seal. This is to ensure that there is no tearing at the side edge as a result of handling the finished bag after filling with a product, if only one seam (either seam or seal seam) is present there.
Bei diesem Stand der Technik ist zu diesem Zweck im Randbereich des Beutels die Trennnaht vorhanden, die die beiden Lagen des Muttermaterials miteinander verbindet Da es zu Rissbildungen kommen kann, wenn nur eine Trennnaht vorhanden ist, ist parallel im Abstand zu der Trennnaht verlaufend eine Siegelnaht vorgesehen. Obwohl durch diese beiden insbesondere parallel verlaufenden Nähte das Aufplatzen des Randbereiches des Beutels, in dem die beiden Lagen des uttermaterials miteinander verbunden sind, deutlich eingeschränkt ist, benötigen die beiden Nähte einen verhältnismäßig breiten Randstreifen, damit sie auf Abstand zueinander vorgenommen werden können. In this prior art, the separating seam is present for this purpose in the edge region of the bag, which connects the two layers of parent material together since it can cause cracking, if only one septum is present, a sealing seam is provided parallel to the separation seam running parallel , Although the bursting of the edge region of the bag, in which the two layers of the uttermaterials are connected to each other, is significantly limited by these two, in particular parallel seams, the two seams require a relatively wide edge strip, so that they can be made at a distance from each other.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Beutels und einen danach hergestellten Beutel zu verbessern, insbesondere Materialverschwendung zu vermeiden. Diese Aufgabe ist durch die Merkmale der beiden unabhängigen Patentansprüche gelöst. The invention is therefore an object of the invention to improve a process for the preparation of a bag and a bag made thereafter, in particular to avoid waste of material. This object is solved by the features of the two independent claims.
Erfindungsgemäß ist vorgesehen, dass die beiden miteinander zu verbindenden Endbereiche des Beutels mit einer Siegelnaht miteinander verbunden werden. Dabei erstreckt sich die Siegelnaht sowohl auf einen und einen weiteren danebenliegenden Beutel, die aus Schlauch-Muttermaterial bestehen, wobei vor dem Einbringen der Siegelnaht die beiden Randbereiche des Muttermaterials noch nicht miteinander verbunden sind. Allerdings ist jede Lage des Muttermaterials im Bereich der noch vorzunehmenden Trennung durchgehend. Nachdem die beiden Lagen des Muttermaterials mit der Siegelnaht beutelübergreifend miteinander verbunden worden sind, wird eine innerhalb der Siegelnaht parallel verlaufende Trennnaht eingebracht, um eine doppelte Verschweißung zur Erhöhung der Dichtigkeit zu erzielen und gleichzeitig die bis dahin noch nebeneinander bzw. hintereinander angeordneten und nicht voneinander getrennten Beutel voneinander zu trennen. Dadurch wird insgesamt nicht nur ein gegenüber dem Stand der Technik schmalerer Streifen im Randbereich des Beutels benötigt, um durch das Einbringen zweier Nähte die Gefahr von Rissbildungen deutlich herab zu setzen und damit die Dichtheit wesentlich zu erhöhen. Gleichzeitig wird das Einbringen zweier Nähte dazu genutzt, auch zwei Beutel voneinander, die vor dem Einbringen der Trennnaht noch nicht voneinander getrennt waren, zu trennen. According to the invention, it is provided that the two end regions of the bag to be connected to one another are connected to one another with a sealed seam. In this case, the sealing seam extends to both one and another adjacent bag, which consist of tube-mother material, wherein the two edge regions of the parent material are not yet connected to each other before the introduction of the sealed seam. However, every position of the parent material in the area of the separation still to be made is continuous. After the two layers of the mother material have been connected with the sealed seam bag across each other, a parallel within the seam seam is introduced to achieve a double weld to increase the tightness and at the same time until then next to each other or arranged one behind the other and not separated Separate bags from each other. As a result, not only is a narrower strip than the prior art required in the edge region of the bag, in order to significantly reduce the risk of crack formation by introducing two seams and thus substantially increase the tightness. At the same time the introduction of two seams is used to separate two bags from each other, which were not yet separated from each other before the introduction of the cutting seam.
Weiterhin ist erfindungsgemäß ein Beutel vorgesehen, der nach dem vorstehend beschriebenen Verfahren hergestellt worden ist. Vorzugsweise besteht dieser Beutel aus zwei Lagen Muttermaterial, die im Randbereich auf geeignete Art und Weise miteinander verbunden sind. Diese Verbindung kann in solchen Bereichen, die nicht rissgefährdet sind bei der Handhabung des Beutels nur eine Naht, z. B. nur eine Trennnaht oder nur eine Siegelnaht sein. Zumindest in denjenigen Bereichen, in denen bei der Handhabung des fertigen Beutels eine Rissbildung zu befürchten ist, wird sowohl eine Siegelnaht als auch eine innerhalb der Siegelnaht parallel zu der Siegelnaht verlaufende Trennnaht vorgesehen. Vorzugsweise erstreckt sich eine soiche Kombination aus Siegeinahi und im Bereich der Siegelnaht parallel dazu verlaufende Trennnaht über zumindest einen gesamten Randbereich (wie z. B. Seitenbereich oder Boden) des Beutels. Furthermore, a bag is provided according to the invention, which has been prepared by the method described above. Preferably, this bag consists of two layers of mother material, which are connected to each other in the edge region in a suitable manner. This compound can be in such areas that are not susceptible to crack when handling the bag only a seam, z. B. only a parting seam or just a sealed seam. At least in those areas in which cracking is to be feared during the handling of the finished bag, both a sealed seam and a separating seam running within the sealed seam parallel to the sealed seam are provided. Preferably, such a combination of sealing seams and, in the region of the sealing seam, a separating seam running parallel thereto extends over at least one entire edge region (such as side region or bottom) of the bag.
Ein Ausführungsbeispiel eines solchen Beutels ist in der Figur gezeigt und im Folgenden beschrieben. An embodiment of such a bag is shown in the figure and described below.
Ein zweitägiges Muttermaterial 1 , hier in Schlauchform, dient als Ausgangsmaterial für die Herstellung mehrerer Beutel. Zur Bildung eines Randbereiches, z. B. eines Bodenbereiches, des Beutels wird eine Siegelnaht 2 (schraffiert) in das Muttermaterial 1 eingebracht. Damit ist ein Randbereich des späteren Beutels sowie ein Randbereich eines weiteren späteren Beutels geschlossen, da die beiden Lagen des Muttermaterials 1 in Transportrichtung TR miteinander verbunden sind. Allerdings sind der eine und der weitere Beutel noch nicht voneinander getrennt. Zu diesem Zweck wird nach dem Einbringen der Siegelnaht 2 eine parallel dazu verlaufende Trennnaht 3 eingebracht, um den einen von dem weiteren Beutel zu trennen. Die Trennnaht 3 verläuft vorzugsweise genau in der Mitte der schmalen Breite der Siegelnaht 2, wobei jedoch auch davon abweichende Anordnungen denkbar sind. Dieser Schritt wird unter Vorschub des Muttermaterials 1 in Transportrichtung TR entsprechend der Länge des schlauchförmigen Muttermaterials 1 mehrfach hintereinander wiederholt, so dass jedes Mal dann, wenn das Muttermaterial 1 mit der Siegelnaht 2 verbunden worden ist, einzelne Beutel durch Einbringen der Trennnaht 3 von dem„endlos"-Muttermateriai 1 abzutrennen. Danach kann der vorgefertigte Beutel entweder seiner Bestimmung zugeführt oder weiterbearbeitet werden. A two-day mother material 1, here in tube form, serves as a starting material for the production of several bags. To form a border area, z. B. a bottom portion of the bag, a sealed seam 2 (hatched) is introduced into the mother material 1. In order for an edge region of the subsequent bag and an edge region of another subsequent bag is closed, since the two layers of the parent material 1 are connected to each other in the transport direction TR. However, one and the other bags are not yet separated. For this purpose, a parallel extending seam 3 is introduced after the introduction of the sealing seam 2 to separate the one from the other bag. The separating seam 3 preferably runs exactly in the middle of the narrow width of the sealed seam 2, but deviating arrangements are also conceivable. This step is repeated several times in succession with feed of the mother material 1 in the transport direction TR corresponding to the length of the tubular mother material 1, so that each time the parent material 1 has been joined to the sealed seam 2, individual pouches are removed by inserting the parting seam 3 from the " endless "mother material 1. After that, the prefabricated bag can either be sent to its destination or further processed.
Diese Art der Erzeugung eines dichten Randbereiches des Beutels kann bei zweilagigem Muttermaterial durchgeführt werden. Das Muttermaterial kann aber auch drei-, vier- oder sogar noch mehr als vierlagig ausgeführt sein. Die vierlagige Ausführung kann beispielsweise auch durch Umklappen (Umfalten) von einem zweilagigen Muttermaterial realisiert werden. This type of production of a dense edge region of the bag can be carried out with two-layer mother material. However, the mother material can also be made three, four or even more than four layers. The four-ply embodiment can also be realized, for example, by folding over (folding over) a two-ply mother material.
Eine besonders bevorzugte Anwendung solcher Art hergestellter Beutel ist darin zu sehen, wenn sie mit Lebensmitteln befüllt werden. Hierbei wirkt sich der erfindungsgemäße Beutel besonders vorteilhaft aus, weil er durch das vorhanden sein von Siegeinaht 2 und Trennnaht 3 besonders gut abgedichtet ist und dadurch verhindert wird, dass das in dem Beute! befindliche Lebensmittel oder Teile davon austreten können bzw. störende vor allen Dingen gesundheitsschädigende Einflüsse von außen durch eine Rissbildung an das Lebensmittel gelangen können. Außerdem wird durch die im Bereich der Siegeinaht 2 befindliche Trennnaht 3 deutlich weniger Muttermaterial 1 benötigt, so dass bei gleichzeitig erhöhter Dichtheit weniger Material für die Herstellung des Beutels erforderlich ist. Als besonders kritisches Füllgut sind frische Geflügel anzusehen, da diese nach dem Einfüllen immer noch Flüssigkeit absondern, die nicht aus dem Beutel austreten darf. Außerdem ist Geflügel besonders anfällig für Störeinflüsse von außen, wenn Risse in dem Beutel vorhanden sind, die nach der Erfindung, zusätzlich zur Materialeinsparung wirksam vermieden werden. A particularly preferred use of such kind of manufactured bags is to be seen when they are filled with food. In this case, the bag according to the invention has a particularly advantageous effect because it can be present through the bag of Siegeinaht 2 and seam 3 is particularly well sealed and thereby prevents that in the prey! located foods or parts thereof may escape or disturbing above all harmful to health influences from the outside by cracking can reach the food. In addition, much less mother material 1 is required by the located in the region of the Siegeinaht 2 seam 3, so that less material is required for the production of the bag at the same time increased tightness. As a particularly critical filling fresh poultry are to be regarded as they still secrete liquid after filling, which may not escape from the bag. In addition, poultry is particularly susceptible to external interference when cracks are present in the bag, which are effectively avoided according to the invention, in addition to saving material.
