Description

Die Erfindung betrifft ein Verfahren zur Herstellung von sogenannten Hemdchenbeuteln, bei dem eine flachliegende, beidseits mit mindestens einer Seitenfalte versehene Schlauchbahn mit die Seitenfaltenbereiche schlaufenartig zu Traggriffen schließenden Kopfschweißnähten, mit die Innenkanten der Seitenfalten erfassenden Hemdchenausschnitten und nach Falten um ihre Längsmittellinie auf sich selbst mit alle Lagen erfassenden Bodenschweißnähten und zwischen den Kopf- und Bodenschweißnähten mit die Beutel trennenden Querperforationen oder Quertrennschnitten versehen wird.The invention relates to a process for the production of so-called shirt bags, in which a flat-lying tubular web provided on both sides with at least one side gusset with welded head seams closing the side gusset areas to form handles, with shirt cutouts capturing the inner edges of the side gussets and after folding around their longitudinal center line on all of them Layer-capturing bottom weld seams and between the head and bottom weld seams with the bag-separating cross perforations or cross cuts.

Ein übliches Verfahren dieser Art zur Herstellung von aus der DE-OS 25 26 961 bekannten Hemdchenbeuteln mit sogenannten Kronenböden wird anhand der Fig. 8 der Zeichnung näher erläutert: Eine mit Seitenfalten 1 versehene Schlauchbahn 2 wird in einem ersten Verfahrensabschnitt mit Hemdchenbeutelausschnitten 3, Kopfnähten 4 und dem Abreißen dienenden Querperforationen 5 versehen. Anschließend wird die derart vorbereitete Schlauchbahn über nicht dargestellte Mittel um ihre Längsmittellinie auf sich gefaltet und die gefaltete Schlauchbahn wird dann mit alle Lagen erfassenden Bodenschweißnähten 6 versehen.A conventional method of this type for the production of shirt bags with so-called crown bottoms known from DE-OS 25 26 961 is explained in more detail with reference to FIG. 8 of the drawing: A tubular web 2 provided with gussets 1 is in a first process section with shirt bag cutouts 3, top seams 4 and the tear-off transverse perforations 5. Subsequently, the tubular web prepared in this way is folded over itself about its longitudinal center line by means not shown, and the folded tubular web is then provided with bottom weld seams 6 covering all layers.

Dieses bekannte Verfahren zur Herstellung von Hemdchenbeuteln mit Kronenböden ist sehr aufwendig, weil dieses eine Vorrichtung mit zwei Schweißstationen bedingt, die im größeren Abstand voneinander angeordnet sein müssen, weil zwischen diesen die Faltstation angeordnet ist. Weiterhin erfordert die bekannte Vorrichtung zur Herstellung der Hemdchenbeutel mit Kronenböden eine aufwendige Steuerung, die gewährleistet, daß die von den beiden Schweißeinrichtungen erzeugten Schweißnähte lagerichtig zunächst an die ungefaltete und dann an die gefaltete Schlauchbahn angebracht werden.This known method for the production of shirt bags with crown bottoms is very complex because it requires a device with two welding stations, which have to be arranged at a greater distance from one another, because the folding station is arranged between them. Furthermore, the known device for producing the shirt bags with crown bottoms requires a complex control which ensures that the weld seams produced by the two welding devices are first positioned correctly on the unfolded and then on the folded tube sheet.

Aufgabe der Erfindung ist es daher, ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 vorzuschlagen, nach dem sich Hemdchenbeutel mit Kronenböden in einfacher Weise mit einer weniger aufwendigen Vorrichtung herstellen lassen.The object of the invention is therefore to propose a method according to the preamble of claim 1, according to which shirt bags with crown bottoms can be produced in a simple manner with a less complex device.

Erfindungsgemäß wird diese Aufgabe bei einem Verfahren der gattungsgemäßen Art dadurch gelöst, daß die Schlauchbahn vor ihrem Falten um die Längsmittellinie im Bereich der späteren Kopfschweißnähte mit ein Verschweißen verhindernden, quer über die Bahn verlaufenden Trennschichten versehen und die Schlauchbahn anschließend derart gefaltet wird, daß die Trennschichten aufeinander liegen, und daß sodann die auf sich gefaltete Schlauchbahn mit den Kopf- und Bodenschweißnähten versehen wird. Zur Durchführung des erfindungsgemäßen Verfahrens ist eine Vorrichtung mit nur einer Schweißeinrichtung erforderlich, so daß nicht nur der Investitionsaufwand geringer ist, sondern auch die Schweißnähte in einfacher Weise lagerichtig zueinander angebracht werden können.According to the invention, this object is achieved in a method of the generic type in that the tubular web, before it is folded around the longitudinal center line in the region of the subsequent head weld seams, is provided with a separating layer which prevents welding and extends across the web, and the tubular web is then folded in such a way that the separating layers lie on top of each other, and then the folded one Hose track is provided with the top and bottom weld seams. To carry out the method according to the invention, a device with only one welding device is required, so that not only is the investment required less, but also the weld seams can be attached to one another in a simple manner in the correct position.

Zweckmäßigerweise wird die gefaltete und mit den Kopf- und Bodenschweißnähten versehene Schlauchbahn mit den die Hemdchenausschnitte bildenden Stanzschnitten versehen. Infolge der mittigen Faltung der Schlauchbahn können dann die Stanzausschnitte entsprechend kleiner gehalten werden.The folded and provided with the top and bottom weld seams is expediently provided with the punched cuts forming the shirt cutouts. As a result of the central folding of the tubular web, the punched cutouts can then be kept correspondingly smaller.

An embodiment of the invention is explained below with reference to the drawing. In this show
  • 1 is a schematic side view of a device for the production of camisole bags with crown bottoms,
  • FIG. 2 shows a plan view of the tubular web processed in the device according to FIG. 1, illustrating the processing steps carried out in the individual processing stations, FIG.
  • 3 to 5 sections through the tubular path along the section lines III - III, IV - IV and V - V in Fig. 2,

  • Fig. 8 is a plan view of a tube sheet explaining the known method for producing shirt bags with crown bottoms.

Wie aus Fig. 1 ersichtlich ist, wird von einer Vorratsrolle 7 eine mit Seitenfalten versehene Schlauchbahn 8 abgezogen. Diese Schlauchbahn 8 durchläuft zunächst ein Auftragswerk 9, in welchem die Bahn 8 einseitig und im gleichen, den Beutellängen entsprechenden Abständen mit streifenförmigen Aufträgen 10 aus Trennlack versehen wird, die sich über die gesamte Breite der Schlauchbahn 8 erstrecken. Anschließend wird die Schlauchbahn 8 durch eine übliche, ein Faltdreieck enthaltende Falteinrichtung 11 um ihre Längsmittellinie auf sich gefaltet, so daß die streifenförmigen Aufträge 10 aus Trennlack innerhalb des durch die Faltung gebildeten Halbschlauchs aufeinander liegen.As can be seen from FIG. 1, a tubular web 8 provided with side folds is drawn off from a supply roll 7. This tubular web 8 first passes through an applicator unit 9, in which the web 8 is provided on one side and at the same spacing, corresponding to the bag lengths, with strip-shaped applications 10 made of release lacquer, which extend over the entire width of the tubular web 8. Subsequently, the tubular web 8 is folded over itself about its longitudinal center line by a conventional folding device 11 containing a folding triangle, so that the strip-shaped applications 10 of separating lacquer lie one on top of the other within the half-tube formed by the folding.

Anschließend durchläuft die so gefaltete Schlauchbahn 8 eine Schweißeinrichtung 12, in der die Schlauchbahn 8 mit den Kopfnähten 13 und den Bodennähten 14 versehen wird.The tubular web 8 folded in this way then passes through a welding device 12, in which the tubular web 8 is provided with the top seams 13 and the bottom seams 14.

Wie aus Fig. 2 zu erkennen ist, verlaufen die Kopfnähte 13 innerhalb der streifenförmigen Aufträge 11 aus Trennlack, so daß in diesen Bereichen jeweils die vier oberhalb und die vier unterhalb der mit Aufträgen 10 aus Trennlack versehenen Bahnen miteinander verschweißt werden. Im Bereich der Bodennähte 14 befindet sich kein Trennlackauftrag, so daß die Schweißnähte 14 durch alle acht Lagen hindurchgehen. Der so gebildete Beutel kann im Bodenbereich nicht aufgeklappt werden, weil hier alle acht Lagen der gefalteten Schlauchbahn 8 miteinander verschweißt sind.As can be seen from FIG. 2, the head seams 13 run within the strip-shaped orders 11 made of release lacquer, so that in these areas the four above and the four below the webs provided with orders 10 made of release lacquer are welded together. In the area of the bottom seams 14 there is no separating lacquer application, so that the weld seams 14 pass through all eight layers. The bag thus formed can Bottom area can not be opened, because here all eight layers of the folded tube sheet 8 are welded together.

Nach dem Anbringen der Kopf- und Bodenschweißnähte wird die gefaltete Schlauchbahn 8 in einer Stanzstation mit den Hemdchenausschnitten versehen, die bis über die Innenkanten der Seitenfalten hinaus ausgeführt werden. Die in der beschriebenen Weise gebildete Beutelkette wird dann in der aus Fig. 1 ersichtlichen Weise zu einer Vorratsrolle aufgewickelt.After the head and bottom welds have been made, the folded tube sheet 8 is provided with the shirt cutouts in a punching station, which are carried out beyond the inner edges of the side gussets. The bag chain formed in the manner described is then wound up into a supply roll in the manner shown in FIG. 1.

Ein von der Beutelkette längs einer Querperforationslinie abgerissener Hemdchenbeutel mit Kronenboden nimmt nach seiner Befüllung die aus Fig. 7 ersichtliche Form an.A shirt bag with a crown bottom torn off from the bag chain along a transverse perforation line assumes the shape shown in FIG. 7 after it has been filled.
