Description

Kaschieren von SpanplattenLaminating chipboard

Die Erfindung betrifft eine Einrichtung zum kontinuierlichen Kaschieren von Spanplatten in Bahnform mit einer Dekorschicht mit und/oder ohne Haftvermittler, wobei das Material zwischen einer Trommel und einem endlosen die Trommel umschlingenden Band kaschiert wird.The invention relates to a device for the continuous lamination of chipboard in web form with a decorative layer with and / or without an adhesion promoter, the material wrapping around the drum between a drum and an endless one Tape is laminated.

Es sind für die Durchführung eines Kaschiervorganges massive Stahlbänder bekannt, wobei das zu kaschierende Material zwischen der umlaufenden Trommel und dem endlosen massiven Stahlband kaschiert wird.There are solid steel strips known for the implementation of a laminating process, with the to concealing material between the rotating drum and the endless solid steel band will.

Beim Einsatz endloser massiver Stahlbänder in entsprechenden Kaschiereinrichtungen hat sich gezeigt, daß bei geringen Deformationen sowo-hl des Stahlbandes selbst als auch hinsichtlich der Dickentoleranz der zu kaschierenden Spanplatte an derartigen Deformationsstellen keine gleichmäßige Anpressung des zu' kaschierenden Materials an die Spanplatte erfolgt. Es wird somit an derartigen Stellen eine mangelhafte bzw. keine Verbindung des zu kaschierenden Materials an die Spanplatte erreicht, d. h., daß die an diesen Stellen eingeschlossene Luft zwischen beiden Materialschichten beim Einlauf inWhen using endless solid steel belts in appropriate laminating devices, it has been shown that that with slight deformations of the steel belt as well itself as well as with regard to the thickness tolerance of the chipboard to be laminated on such Deformation points, the material to be laminated is not evenly pressed against the chipboard he follows. It becomes a Inadequate or no connection between the material to be laminated and the chipboard is achieved, d. H., that the air trapped at these points between the two layers of material when entering

den Spalt zwischen der Trommel und dem endlosen Band nicht herausgepreßt wird.the gap between the drum and the endless belt is not pressed out.

Während nun das zu kaschierende Material eingepreßt zwischen der Walzentrommel und dem unter Zugspannung stehenden endlosen Druckband die beheizte Trommel umschlingt, wird die an diesen Stellen eingeschlossene Luft erwärmt und dehnt sich aus, wodurch ein Verschweißen bzw. Verkleben, beispielsweise einer Dekorschicht, die mittels eines Haftvermittlers beispielsweise einer Polyäthylen-Folie an eine dünne Spanholzplatte kaschiert werden soll, verhindert wird, weil ein massives Stahlband sich Unebenheiten nicht anpassen kann.While now the material to be laminated is pressed between the roller drum and the under Tension standing endless pressure belt wraps around the heated drum, is applied to this Places enclosed air heats and expands, causing welding or sticking, for example a decorative layer, which by means of an adhesion promoter, for example a Polyethylene film is to be laminated to a thin chipboard, is prevented because a massive steel band cannot adapt to unevenness.

Weiterhin ist die Lebensdauer eines massiven Stahlbandes wesentlich geringer, weil durch die vielen Wechselbiegungen, Spannungen in das Band gebracht werden, wodurch sich nach einer bestimmten Betriebszeit Ermüdungserscheinungen zeigen.Furthermore, the service life of a solid steel belt is much shorter because of the many Alternating bends, stresses are brought into the belt, causing it to change after a certain period of operation Show signs of fatigue.

Die Aufgabe der Erfindung besteht darin, diesen Mangel beim Kaschieren von Spanholzplatten mittels anderen Materialien zu beheben.The object of the invention is to remedy this deficiency when laminating chipboard panels by means of fix other materials.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß das endlose unter Zugspannung stehende, dieThe object of the invention is achieved in that the endless under tension, the

beheizte Trommel teilweise umschlingende Band, ein Stahldrahtseilgewebe ist, welches sich bei der Verpressung der zu kaschierenden Materialien allen Dickentoleranzen und Unebenheiten des zu kaschierenden Materials anpaßt und somit einen während der Umschlingung der beheizten Trommel vollkommen gleichmäßigen Druck erzeugt und eine gute Kaschierung gewährleistet.heated drum partially wrapping belt, a steel wire rope mesh, which is at the pressing of the materials to be laminated, all thickness tolerances and unevenness of the to laminating material and thus a generated during the wrapping of the heated drum perfectly even pressure and a good lamination guaranteed.

In weiterer Ausgestaltung der Erfindung wird das endlose Stahldrahtseilgewebe mit einer elastischen Schicht aus einer vulkanisierten mit dem Stahldraht seil gewebe mittels Haftvermittler verbundenen Gummibahn belegt und umschlingt die beheizte Trommel mindestens um l/4 des Trommelumfanges*In a further embodiment of the invention, the endless steel wire rope fabric with an elastic Layer of a vulcanized fabric connected to the steel wire rope by means of an adhesion promoter Rubber sheet covers and wraps around the heated drum at least by 1/4 of the drum circumference *

Der Vorteil beim Einsatz eines mit einem Gummibelag beschichteten Stahldrahtseilgewebes zum Kaschieren von wenig elastischen Spanplattenbahnen ist insbesondere darin zu sehen, daß sich ein derartiges endloses Druckband auch den geringsten Unebenheiten sowohl der Spanplattenbahn selbst als auch der Dekorschicht 100%ig anpaßt und somit eine ausgezeichnete Kaschierung der Spanplattenbahnen mit anderen Materialien erreicht wird.The advantage of using a steel wire rope fabric coated with a rubber covering for the lamination of less elastic chipboard webs is to be seen in particular in the fact that such an endless printing belt adapts 100% to even the slightest unevenness of both the chipboard web itself and the decorative layer and thus an excellent lamination of the Chipboard sheets with other materials is achieved.

Ein Ausführungsbeispiel des erfindungsgemäßen endlosen Bandes in einer Kaschiereinrichtung wird in An embodiment of the endless belt according to the invention in a laminating device is shown in FIG
