Abstract

The method is used for producing a half-tube web from which fillable and closable bags can be produced. The half-tube web consists of a material which is capable of being adhesively bonded and/or sealed. In the region of the first of the two longitudinal outer edges (8) running in the direction of feeding of the half-tube web, at least one continuous strip (17) is fitted in each case to the top side and to the underside of the half-tube web in pockets which are continuously integrally formed on the web during its feeding, before the separation and filling and subsequent closing of the bags from the open, second longitudinal outer edge which is parallel to the first longitudinal outer edge. In this method, before the strips are fitted in the pockets, parts (12) of the half-tube web are punched out at an interval corresponding to one bag width in the region of the first longitudinal outer edge. After the continuous strips have been fitted, they are then separated in the region of the punched-out part and the two separated, adjacent ends of the top side and underside are interconnected without nodes (20). <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Halbschlauch-Bahn gemäß dem Oberbegriff des Haupt­anspruchs.The invention relates to a method for producing a half-tube web according to the preamble of the main claim.

Bei diesem bekannten Verfahren wird die Halbschlauch­bahn hergestellt und zugleich kontinuierlich die Bänder, Schnüre, Kordeln oder dergleichen in Taschen an der Ober- und Unterseite der Längsaußenkante angebracht. Danach werden die einzelnen Beutel quer zur Vorschub­richtung abgesiegelt, die Beutel dabei auseinandergezo­gen, um das für den nachfolgenden Knotvorgang erforderliche Maß an Band zu haben. Danach erfolgt das Verknoten der Bandenden. Die fertig hergestellten vereinzelten Beutel werden dann auf Halteröhrchen im Bereich zuvor angebrachter Ausstanzungen gesammelt.In this known method, the semi-tubular web is produced and at the same time the tapes, cords, cords or the like are continuously attached in pockets on the top and bottom of the longitudinal outer edge. The individual bags are then sealed transversely to the feed direction, the bags being pulled apart in order to have the required amount of tape for the subsequent knotting process. Then the ends of the tape are knotted. The finished individual bags are then collected on holding tubes in the area of previously punched holes.

Bei den bekannten Verfahren ist es nicht möglich, ma­schinell eine Kordel größeren Durchmessers anzubringen. Solche Beutel müssen manuell hergestellt werden. Um dennoch solche für schweres Gut einsetzbare Beutel ein­setzen zu können, ist es erforderlich, einen zusätzli­chen Griff in Form eines dickeren Kunststoffteils im Bereich der ersten Längsaußenkante durch Schweißen anzu­bringen.In the known methods, it is not possible to mechanically attach a cord of larger diameter. Such bags have to be made manually. In order to be able to use such bags that can be used for heavy goods, it is necessary to attach an additional handle in the form of a thicker plastic part in the region of the first longitudinal outer edge by welding.

Von Nachteil bei diesen bekannten Verfahren ist der große Verbrauch an Band, welches zum Knoten erforderlich ist. Ferner ist aufgrund des Verknotens das Verfahren langsam. Schließlich ist es für das Knoten erforder­lich, die Beutel herzustellen und zu vereinzeln. Danach ist dann das manuelle Sammeln und Aufstecken erforderlich, ganz abgesehen davon, daß dicke Bänder nur manuell eingelegt werden können, oder aber statt dessen ein gesondertes Teil im Bereich der ersten Längsaußen­kante eingeschweißt werden muß.A disadvantage of these known methods is the large amount of tape that is required for knotting. Furthermore, the procedure is due to the knotting slowly. Finally, it is necessary for the knot to make and separate the bags. Then manual gathering and plugging is required, quite apart from the fact that thick tapes can only be inserted manually, or instead a separate part must be welded in the area of the first longitudinal outer edge.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungs­gemäßes Verfahren so auszugestalten, daß kontinuierlich eine zusammenhängende Halbschlauchbahn erhalten werden kann, deren Weiterverarbeitung durch quer zur Vorschub­richtung erfolgendes Trennsiegeln und Befüllen sowie Verschließen des solchermaßen gefüllten Beutels im Bereich der zweiten Längsaußenkante ermöglichen soll, ohne daß nach dem Vereinzeln der Beutel ein Verknotungs­vorgang erforderlich ist. Außerdem sollen auch dicke Bänder verarbeitbar sein.The invention has for its object to design a generic method so that a coherent semi-tubular web can be continuously obtained, the further processing of which is to be made possible by separating sealing and filling and closing the bag filled in this way in the region of the second longitudinal outer edge without having to after Separating the bags requires a knotting process. It should also be possible to process thick strips.

Diese Aufgabe wird bei einem gattungsgemäßen Verfahren gemäß dem Oberbegriff des Hauptanspruchs erfindungsge­mäß durch dessen kennzeichnende Merkmale gelöst.This object is achieved in a generic method according to the preamble of the main claim according to the invention by its characterizing features.

Erfindungsgemäß wird also ein Abtrennen des Bandes in Beutelbreite und Verbinden der abgetrennten Bänder er­reicht, ohne daß es erforderlich ist, die Beutel zu ver­einzeln. Infolgedessen kann die Halbschlauchbahn rollen- oder zickzackförmig gespeichert werden und liegt in dieser Form zur Weiterverarbeitung bei dem Hersteller des Produkts vor, welches in die Beutel gepackt werden soll. Ferner ergibt sich eine beträchtliche Materialer­sparnis am Band, weil dieses nur genau in der Beutel­breite benötigt wird.According to the invention, a separation of the tape in bag width and connection of the separated tapes is achieved without the need to separate the bags. As a result, the semi-tubular web can be stored in roll or zigzag form and is in this form for further processing at the manufacturer of the product which is to be packed in the bags. Furthermore, there is considerable material savings on the belt because this is only required in the exact width of the bag.

In zweckmäßiger Ausgestaltung der Erfindung können auch zwischen je zwei zueinander benachbarter ausgestanzter Teile eine gesonderte Ausstanzung unter Unterbrechung der ersten Längsaußenkante vorgesehen sein, so daß an dieser Stelle das Band zur Verwendung als Tragschlaufe herausgezogen werden kann, die ein Tragen des Beutels zu zweit oder über die Schulter zuläßt.In an expedient embodiment of the invention, a separate punching can also be provided between two mutually adjacent punched-out parts, with the interruption of the first longitudinal outer edge, so that at this point the band can be pulled out for use as a carrying loop, which can be used to carry the bag in pairs or via the Shoulder allows.

  • Figur 1 die Herstellung der Halbschlauchbahn, in perspektivischer Darstellung;
  • Figur 2 die Halbschlauchbahn mit angebrachten Bän dern und ausgestanzten Teilen, in abgebro­chener Darstellung;
  • Figur 3 den Verfahrensschritt des Abtrennens der Bän­der, in teilweise abgebrochener schematischer perspektivischer Darstellung und
  • Figur 4 das Verbinden benachbarter Enden der benach­barten Bänder.
A preferred embodiment of the invention is explained in more detail below with reference to the drawing. In this shows:
  • Figure 1 shows the production of the semi-tubular web, in a perspective view;
  • Figure 2 shows the semi-tubular web with attached bands and punched parts, in a broken view;
  • Figure 3 shows the process step of severing the strips, in a partially broken schematic perspective view and
  • Figure 4 connecting adjacent ends of the adjacent tapes.

In Figur 1 ist eine insgesamt mit 5 bezeichnete Umlenkrolle dargestellt, um die in Vorschubrichtung 6 die insgesamt mit 7 bezeichnete Halbschlauchbahn herum­geführt wird. Die Halbschlauchbahn ist auf der einen ersten Längsaußenkante 8 mit einer einwärtslaufenden Falte 9 versehen. Die andere der beiden zu der ersten parallel verlaufende zweite Längsaußenkante 10 verläuft am offenen Teil der Halbschlauchbahn 7. In diesem Bereich sind einzelne Schweißpunkte (21) angebracht um die beiden Teile der Halbschlauchbahn aneinanderzuhef­ten.FIG. 1 shows a deflection roller, generally designated 5, around which the semi-tubular web, generally designated 7, is guided in the feed direction 6. The semi-tubular web is provided with an inward running fold 9 on the first longitudinal outer edge 8. The other of the two second longitudinal outer edge 10 running parallel to the first runs on the open part of the half-tube web 7. In this area, individual welding spots (21) are attached in order to attach the two parts of the half-tube web together.

In einer ersten Arbeitsstation werden im Abstand einer Beutelbreite 11 (Figur 2) Teile 12 der Halbschlauchbahn 7 halbkreisförmig zusammen mit dazwischenliegenden ge­sonderten rechteckförmigen Ausstanzungen 13 so ausge­stanzt werden, daß die erste Längsaußenkante 8 mit un­terbrochen wird.In a first work station, parts 12 of the semi-tubular web 7 are punched out in a semicircle at a distance of a bag width 11 (FIG. 2) together with separate rectangular punched-outs 13 in between such that the first longitudinal outer edge 8 is also interrupted.

Nach diesem ersten, in der Zeichnung nicht gesondert ausgewiesenen Arbeitsgang werden im Bereich der ersten Längsaußenkante 8 der Halbschlauchbahn 7 auf der infolge der Falte 9 gebildeten Oberseite 14 und der Unterseite 15 (Figur 3) Taschen 16 mit einem darin eingelegten, fortlaufenden Band 17 angeformt, so daß sich die in Figur 2 gezeigte Habschlauchbahn 7 ergibt. In einem nachfolgenden Arbeitsgang werden im Bereich der ausge­stanzten Teile 12 die Bänder 17 abgetrennt (Figur 3). In einem nachfolgenden Arbeitsgang werden dann die zwei abgetrennten benachbarten Enden 18, 19 der Oberseite 14 und der Unterseite 15 der Halbschlaucbahn 7 ohne Knoten dadurch miteinander verbunden, daß ein Kunststofftropfen 20 aufgespritzt wird.After this first operation, which is not shown separately in the drawing, in the region of the first longitudinal outer edge 8 of the semi-tubular web 7, pockets 16 are formed on the upper side 14 and the lower side 15 (FIG. 3) formed as a result of the fold 9, with a continuous band 17 inserted therein, so that the Habschlauchbahn 7 shown in Figure 2 results. In a subsequent operation, the strips 17 are cut off in the area of the punched-out parts 12 (FIG. 3). In a subsequent operation, the two separated adjacent ends 18, 19 of the upper side 14 and the lower side 15 of the half-hose web 7 are then connected to one another without knots in that a plastic drop 20 is sprayed on.

Danach wird die solchermaßen hergestellte Halbschlauchbahn 7 ohne Abtrennen der einzelnen Beutel fortlaufend aufgerollt oder zickzackförmig in ein Behältnist eingelegt und dieses Behältnis oder die Rolle zu dem Verwender transportiert, wo dann das Vereinzeln und Befüllen der vereinzelten Beutel von der Seite der zweiten Längsaußenkante 10 erfolgt, an der der Beutel noch offen ist.Thereafter, the semi-tubular web 7 thus produced is continuously rolled up or zigzag-shaped placed in a container without separating the individual bags and this container or the roll is transported to the user, where the separation and filling of the separated bags from the side of the second longitudinal outer edge 10 on which the bag is still open.
