Description
Verfahren für das Anbringen eines Verschlussbandes an einem Kunststoffsack
Die Erfindung betrifft ein Verfahren für das Anbringen eines Verschlussbandes an einem Kunststoffsack, welcher aus einer Halbschlauchfolie, oder einer Schlauchfolie, die einseitig aufgeschnitten wird, durch Schweissen von quer verlaufenden Seitennähten und Trennen der Folie zwischen zwei Seitennähten hergestellt wird.
Der Erfinder hat sich die Aufgabe gestellt, bei der Herstellung eines Kunststoffsackes in der beschriebenen Weise gleichzeitig am Sack ein Verschlussband anzubringen.
Gemäss dem erfindungsgemässen Verfahren geschieht dies dadurch, dass ein Verschlussband von einer Vorratsrolle abgezogen und mit der Sackfolie transportiert und dabei an eine Sackseitenwand örtlich angeschweisst und anschliessend bei der Bildung der Seitennähte auch an den Stellen dieser Nähte mitverschweisst wird.
Das Verschlussband kann auf diese Weise an dem Kunststoffsack angebracht werden, ohne dass dafür ein besonderer Arbeitsgang notwendig ist.
Das erfindungsgemässe Verfahren wird nachstehend anhand einer aüf der Zeichnung gezeigten Vorrichtung beispielsweise beschrieben.
Fig. 1 ist eine Seitenansicht der Vorrichtung und
Fig. 2 ein Grundriss derselben.
Eine aus Kunststoff bestehende Halbschlauchfolie 1, die vorne offen ist, ist auf einer Rolle 2 gespeichert und läuft über mehrere Umlenkwalzen 3. Ein Verschlussband 4, das ebenfalls aus Kunststoff bestehen kann, läuft von der Bandspule 5 zur Bandführung 6 und wird durch eine Walze 7 gegen die Folie 1 gedrückt.
An der Schweissstation 8 der Vorrichtung werden die beiden Hälften an der vorderen offenen Seite voneinander getrennt und die obere Folienwand wird mit dem Verschlussband 4 verschweisst, so dass eine Schweissstelle 9 entsteht. Die Halbschlauchfolie 1 und das Verschlussband 4 gelangen nun an die Schweiss- und Trennstation 10, an welcher zwei parallele, quer verlaufende Seitennähte 11 und 12 in der Folie 1 erzeugt und gleichzeitig das Band 4 mitverschweisst wird. Zwischen den Seitennähten 11, 12 wird die Folie 1 getrennt, so dass nun der rechts in Fig. 1 und 2 ersichtliche Sack entsteht, der vorn offen und hinten zweckmässig einen einwärtsgefalteten Boden sowie die Seitennähte 11, 12 aufweist und an den das Band 4 an drei Stellen angeschweisst ist.
Bei Benutzung des Sackes kann das Band 4 von den beiden Seitennähten 11, 12 gelöst werden, so dass es nur noch in der Mitte bei 9 mit dem Sack verbunden ist. Mit diesem Band kann der gefüllte Sack dann verschlossen werden.
Wenn für die Herstellung eines Kunststoffsackes statt einer Halbschlauchfolie eine Schlauchfolie benutzt wird, weist die Vorrichtung vor der Schweissstation 8 noch eine Schneidvorrichtung auf, durch welche die Schlauchfolie in an sich bekannter Weise vorn aufgeschnitten wird, um die Sacköffnung zu bilden.

Procedure for attaching a sealing tape to a plastic bag
The invention relates to a method for attaching a closure tape to a plastic bag, which is made from a semi-tubular film or a tubular film that is cut open on one side by welding transverse side seams and separating the film between two side seams.
The inventor has set himself the task of simultaneously attaching a closure tape to the sack when producing a plastic sack in the manner described.
According to the method according to the invention, this is done by pulling a fastener tape off a supply roll and transporting it with the sack film, locally welding it to a sack side wall and then also welding it at the locations of these seams when the side seams are formed.
In this way, the closing tape can be attached to the plastic bag without a special operation being necessary.
The method according to the invention is described below using an apparatus shown in the drawing, for example.
Fig. 1 is a side view of the device and
Fig. 2 is a plan view of the same.
A semi-tubular film 1 made of plastic, which is open at the front, is stored on a roll 2 and runs over several deflection rollers 3. A sealing tape 4, which can also be made of plastic, runs from the tape reel 5 to the tape guide 6 and is driven by a roller 7 pressed against the film 1.
At the welding station 8 of the device, the two halves are separated from one another on the open front side and the upper film wall is welded to the closure tape 4, so that a weld point 9 is created. The semi-tubular film 1 and the sealing tape 4 now reach the welding and separating station 10, at which two parallel, transverse side seams 11 and 12 are produced in the film 1 and the tape 4 is welded at the same time. The film 1 is separated between the side seams 11, 12, so that the bag shown on the right in FIGS. 1 and 2 is created, which has an inwardly folded base and the side seams 11, 12 to which the band 4 adjoins three places is welded.
When the sack is used, the band 4 can be detached from the two side seams 11, 12 so that it is only connected to the sack in the middle at 9. The filled sack can then be closed with this strap.
If a tubular film is used instead of a semi-tubular film for the production of a plastic sack, the device in front of the welding station 8 also has a cutting device by which the tubular film is cut open at the front in a manner known per se to form the bag opening.
PATENT CLAIM
A method for attaching a sealing tape to a plastic bag, which is made from a semi-tubular film or a tubular film that is cut open on one side, by welding transverse side seams and separating the film between two side seams, characterized in that a sealing tape is pulled off a supply roll and transported with the bag film and is locally welded to a bag side wall and then also welded together at the points of these seams when the side seams are formed.
