Description

Die Verbindung von Folien, im besonderen Kunststoffolien, z.B. zur Herstellung der Längsnähte an Beuteln in Verpackungsmaschinen geschieht in fast allen Fällen mittels Wärme, sofern es sich um thermoplastische Folien handelt oder um Folien, welche mit einem thermoplastischen Belag beschichtet sind oder einen wärmeempfindlichen Kleber aufgetragen haben. Dabei wird eine erhitzte Schiene auf die zu verbindende Stelle gedrückt und dadurch die sich berührenden Folien entweder verschmolzen oder, wenn sich nur die Oberflächen der Folien verbinden - versiegelt. Dieser Vorgang ist allgemein bekannt und wird in vielen Packmaschinen prinzipiell so gehandhabt.The connection of foils, in particular plastic foils, e.g. for the production of the longitudinal seams on bags in packaging machines, is done in almost all cases by means of heat, provided that it is thermoplastic foils or foils that are coated with a thermoplastic layer or have applied a heat-sensitive adhesive . A heated rail is pressed onto the point to be connected, thereby either fusing the touching foils or, if only the surfaces of the foils connect, sealing them. This process is well known and is basically used in many packaging machines.

Der Nachteil ist jedoch, daß bei jedem Siegelvorgang die beheizte Schiene die Folie während des Andrückens blockiert, d.h. die Folie kann nicht kontinuierlich laufen; die Maschinen arbeiten intermittierend.The disadvantage, however, is that the heated rail blocks the film during every sealing process, i.e. the film cannot run continuously; the machines work intermittently.

In vielen Fällen ist es jedoch von Vorteil, einen kontinuierlichen Maschinen- oder Folienlauf zu erreichen.In many cases, however, it is advantageous to achieve a continuous machine or film run.

Bei dem anzumeldenden Verfahren handelt es sich um eine Schiene oder ein Siegelelement, welches eine vibrationsähnliche hämmernde Bewegung auf die Folie ausführt. Durch dieses Behämmern in rascher Folge entsteht ebenso eine Verbindung der Folien wie durch das normale Aufdrücken der Siegelelemente nur mit dem Unterschied, daß die Folien nicht während der ganzen Dauer der Versiegelung festgehalten werden, sondern nur für kurze Momente. Die Folien können praktisch zwischen die Siegelelemente kontinuierlich durchgezogen werden, wobei sich die Durchlaufgeschwindigkeit nach der Höhe und Stärke der Vibrationsbewegung der Siegelelemente richtet.The method to be registered is a rail or a sealing element that performs a vibration-like hammering movement on the film. This pounding in rapid succession creates a connection between the foils as well as normal pressing on of the sealing elements, with the only difference that the foils are not held for the entire duration of the seal, but only for short moments. The foils can practically be pulled through continuously between the sealing elements, the throughput speed depending on the level and strength of the vibration movement of the sealing elements.

Weiter ist es möglich, die Folien durch Strahlung, Heißgas o.ä. zu erwärmen und sofort anschließend durch hämmernde kalte Siegelelemente die plastisch gewordenen Oberflächen zu verbinden und gleichzeitig zu kühlen.It is also possible to heat the foils by radiation, hot gas or the like and then immediately afterwards to connect the surfaces that have become plastic by hammering cold sealing elements and to cool them at the same time.

Außerdem ist es möglich, durch einen entsprechenden Anstellwinkel der Vibrationsbewegung der Siegelelemente zur Folie, diese in Bewegung zu versetzen.In addition, it is possible to set the sealing elements in motion by means of a corresponding angle of incidence of the vibration movement of the sealing elements in relation to the film.
