Verfahren zum Heißkleben und Schneiden einer Anordnung'aus übereinanderliegenden Lagen einer thermoplastischen Folie und Vorrichtung zur Ausführung des Verfahrens.Method for hot gluing and cutting an arrangement superimposed layers of a thermoplastic film and device for carrying out the method.

Die Erfindung bezieht sich auf ein Verfahren zum Heißkleben und Schneiden einer Anordnung aus übereinanderliegenden Lagen einer thermoplastischen Folie entlang einer Linie, bei dem die Lagen festgeklemmt und geschnitten werden, sowie auf eine Vorrichtung zur Ausführung dieses Verfahrens. ■The invention relates to a method for hot gluing and cutting an arrangement of layers lying one on top of the other a thermoplastic film along a line in which the layers are clamped and cut, and on a device to carry out this procedure. ■

Es sind zahlreiche Verfahren zum Heißkleben und Schneiden thermoplastischer Folien bekannt, bei denen ein erwärmtes Messer oder ein Draht oder impulsbeheizte Drähte oder Metallbänder verwendet werden, welch letztere so angeordnet sind, daß ein Rand des Bandes mit der thermoplastischen Folie in Eingriff kommt, oder die flache Seite des Bandes die Folie berührt. Die bekannten Verfahren weisen jedoch zahlreiche Nachteile auf. So ergeben sie z.B. keine optimale Abdichtung an den Schweißrändern von gerichteten, wärmeschrumpfbaren thermoplastischen Folien, die Heißklebevorgänge können nur intermittierend durchgeführt werden, sie laufen verhältnismäßig langsam ab, hängen von der Art der thermoplastischen Folie ab und es tritt häufig eine Materialanhäufung auf. Außerdem werden die Heizquellen in Form von Drähten oder Bändern sowie die Messer zum Abtrennen der Folien leicht von dem geschmolzenen Folienmaterial überzogen, und verschmutzt,so daß sie ihre Funktion nicht mehr einwandfrei ausführen können. Ein weiterer Nachteil ist der, daß die Abdeckung auf den Gegendruckschienen für die Trennmesser leicht zerstört wird, so daß ein häufiges Auswechseln erforderlich ist, und im Falle von Draht- oder Band-Heißklebeelementen können diese leicht zerstört werden. Die Verschmutzung üerThere are numerous methods of hot gluing and cutting thermoplastic Films known in which a heated knife or a wire or pulse-heated wires or metal strips are used the latter being arranged so that one edge of the tape engages the thermoplastic film, or the flat one Side of the tape touches the foil. However, the known methods have numerous disadvantages. For example, they do not result in any Optimal sealing at the welding edges of oriented, heat-shrinkable thermoplastic films, the hot-melt adhesive processes can only be carried out intermittently, they proceed relatively slowly, depend on the type of thermoplastic Foil off and there is often a build-up of material. Also, the heating sources are in the form of wires or tapes as well as the Knife for separating the foils slightly coated by the molten foil material, and soiled, so that they do their function can no longer work properly. Another disadvantage is that the cover on the counter pressure rails for the cutting knife is easily destroyed, requiring frequent replacement, and in the case of wire or tape hot-melt adhesive elements these can easily be destroyed. The pollution over

Trennmesser und Heizquellen sowie der elektrisch beheizten Messer rührt also vor allem daher, daß diese bei den bekannten Verfahren in Berührung mit den Folienlagen kommen, während der Heißversiegel-Vorgang durchgeführt wird.Separating knife and heating sources and the electrically heated knife is mainly due to the fact that these are used in the known processes come into contact with the film layers during the heat sealing process is carried out.

Der Erfindung liegt die Aufgabe zugrunde, die obigen Mangel bekannter Verfahren zu vermeiden und ein Verfahren anzugeben, bei dem eine Strahlungsheizquelle verwendet wird, die die Trennung und Verschweißung der Folienlagen ausführt, ohne diese zu berühren, wobei die Heißklebung schnell und wirkungsvoll ausgeführt werden soll.The invention is based on the object of making known the above deficiencies Process to avoid and specify a process that uses a radiant heating source that does the separation and welding of the film layers without touching them, whereby the hot-melt adhesive should be carried out quickly and effectively.

Gemäß der Erfindung wird diese Aufgabe bei einem Verfahren der eingangs bezeichneten Art dadurch gelöst, daß die Lagen zunächst entlang den beiden Seiten der Linie zusammengeklemmt werden, daß anschließend eine Strahlungsheizquelle gegen die zusammengeklemmten Lagen entlang der Linie vorwärts bewegt wird, ohne die Lagen zu berühren, wodurch die Lagei/entlang der Linie aufgeheizt und geschmolzen werden und ein Spalt in den zusammengeklemmten Lagen entlang der Linie ausgebildet wird. Die Strahlungsheizquelle wird hierbei durch das geschmolzene Folienmaterial weder überzogen noch sonstwie verschmutzt und die Einklemmung der übereinanderliegenden Folienlagen gewährleistet zusammen mit der Wärme von der Strahlungsheizquelle die Ausbildung von Schweißwülsten mit optimaler ^ Festigkeit und Dichtheit. Nach dem erfindungsgemäßen Verfahren können ferner thermoplastische Folien mit einer Vielzahl von Öffnungen nach einem gewünschten Schema versehen werden. Außerdem können die thermoplastischen Folien miteinander in einer sich überlappenden Klebenaht heißversiegelt werden.According to the invention, this object is achieved in a method of the opening paragraph designated type solved in that the layers are first clamped together along the two sides of the line, that then a radiant heating source is moved forward against the clamped layers along the line without touching the layers, causing the layer to be heated and melted along the line and a gap is formed in the clamped sheets along the line. The radiant heating source is here neither coated nor otherwise contaminated by the melted film material and the jamming of the superimposed Foil layers, together with the heat from the radiant heating source, ensure the formation of weld beads with optimum ^ Strength and tightness. According to the method according to the invention Furthermore, thermoplastic films can be provided with a multiplicity of openings according to a desired scheme. aside from that the thermoplastic films can be heat-sealed to one another in an overlapping adhesive seam.

Es ist zwar bereits ein Verfahren zum Verschweißen thermoplastischer Folien bekannt,das mit einem Heißgasstrom arbeitet. ^ Es sieht jedoch keine vorherige Zusammenklemmung der miteinander «o zu verschweißenden Folienlagen vor und ermöglicht auch nicht _* ohne weiteres deren Auftrennung.

Der zusammengeklemmte Teil der übereinanderliegenden Lagen kann fortlaufend gegen die Heizquelle vorwärts bewegt werden, um stetig einen Spalt in dem vorderen Rand des zusammengeklemmten Teils auszubilden.The clamped together part of the superimposed layers can continuously advanced against the heat source to steadily leave a gap in the leading edge of the clamped part to train.

Zur Ausführung des Verfahrens geht die Erfindung aus von einer Vorrichtung mit einer ersten Fläche und einer zweiten von der ersten Fläche im Abstand angeordneten Fläche, die einen ersten Hohlraum bilden, einer dritten Fläche und einer vierten im Abstand von der dritten angeordneten Fläche, die einen zweiten Hohlraum bilden, wobei die erste und die zweite Fläche zusammen und die dritte und vierte Fläche zusammen die übereinanderliegenden Folienlagen zwischen sich aufnehaen, mit einer linearen Strahlungsheizquelle in dem ersten Hohlraum, einer Einrichtung, die das erste und zweite Paar von Flächen aus einer getrennten Stellung relativ gegeneinander bewegt, wobei die erste und dritte Fläche und die zweite und vierte Fläche gemeinsam die Folienlagen einklemmen und zwischen sich einen eingeklemmten Abschnitt der Folienlagen ausbilden, und mit einer Einrichtung, die die Heizquelle relativ gegen den eingeklemmten Folienteil bewegt, wodurch dem eingeklemmten Teil der Folienlagen durch die Heizquelle Wärme zuführbar ist und ein Spalt in dem eingeklemmten Teil ausgeschmolzen sowie die Ränder der übereinanderliegenden Folienlagen miteinander verschmolzen werden, die den Spalt begrenzen. Gemäß der Erfindung wird die Einrichtung zur Bewegung der Flächen so gesteuert, daß die Flächen zunächst die Folienlagen einklemmen und die Einrichtung zur Bewegung der Heizquelle ist so steuerbar, daß sie anschließend die Heizquelle gegen die eingeklemmten Folienlagen bewegt. To carry out the method, the invention is based on a device with a first surface and a second surface arranged at a distance from the first surface, which form a first cavity, a third surface and a fourth surface, which is a second surface, arranged at a distance from the third surface Form cavity, the first and second surfaces together and the third and fourth surfaces together sandwiching the superimposed film layers, with a linear radiant heating source in the first cavity, a device which moves the first and second pairs of surfaces from a separated position relative moved against each other, wherein the first and third surface and the second and fourth surface together clamp the film layers and form a clamped portion of the film layers between them, and with a device that moves the heat source relatively against the clamped film part, whereby the clamped part of the film layers through the Hei zquelle heat can be supplied and a gap in the clamped part melted and the edges of the superimposed film layers are fused together, which limit the gap. According to the invention, the device for moving the surfaces is controlled so that the surfaces first clamp the film layers and the device for moving the heating source is controllable so that it then moves the heating source against the clamped film layers.
