Description

Die Erfindung betrifft ein Preßpolster für den Einsatz in Laminierpressen mit einem Gewebe aus sich kreuzenden Fäden, wobei Fäden vorhanden sind, welche einen Seelenfaden aufweisen, der Wenigstens an seiner Außenseite aus einem gummielastischen Werkstoff besteht und von wenigstens einem Metalldraht umgeben sind.The invention relates to a press pad for use in Laminating presses with a fabric made of crossing threads, there are threads which are a soul thread have, at least on the outside of a rubber-elastic material and of at least one Metal wire are surrounded.

Die Herstellung von Schichtmaterialien, beispielsweise dekorativen Spanplattenbeschichtungen, erfolgt in Laminierpressen, die als Nieder- oder Hochdrucketagenpressen oder Kurztaktpressen ausgebildet sein können. Dabei werden Preßpolster eingesetzt, die die Aufgabe haben, den Druck vollflächig und gleichmäßig auf das Preßgut zu übertragen. Die Preßpolster müssen hohe Drücke und auch die in solchen Pressen vorhandenen Temperaturen standhalten können, und sie müssen in der Lage sein, die von den Preßplatten ausgehende Wärme schnell und ohne große Verluste auf das Preßgut überzuleiten, also eine hohe Wärmeleitfähigkeit in dieser Richtung zu haben.The production of layer materials, for example decorative chipboard coatings, done in laminating presses, which as low or high pressure floor presses or short-cycle presses can be formed. In doing so Press pads used to do the job Full pressure on the material to be pressed evenly transfer. The press pads need high pressures as well withstand the temperatures in such presses can, and they must be able to respond to those of the Press plates outgoing heat quickly and without major losses to transfer to the pressed material, so a high thermal conductivity to have in this direction.

Im Stand der Technik sind Preßpolster bekannt, welche aus einem Gewebe bestehen, das zwei Arten von Fäden umfaßt (EP 0 493 630 A1). Bei einer ersten Gruppe bestehen die Fäden aus Metall oder haben einen Metallanteil, um den Wärmeübergang zum Preßgut zu verbessern. Für die zweite Gruppe von Fäden werden verschiedene Vorschläge gemacht, beispielsweise Fäden aus aromatischem Polyamid (EP 0 493 630 A1), aus Siliconelastomer (DE 295 18 204 U1) oder aus Gummi, hitzbeständigem Kunststoffmonofilament oder dergleichen (EP 0 713 762).Press pads are known in the prior art, which are made of a fabric consisting of two types of threads (EP 0 493 630 A1). In a first group there are Threads made of metal or have a metal component around which To improve heat transfer to the pressed material. For the second Group of threads different suggestions are made for example threads made from aromatic polyamide (EP 0 493 630 A1), made of silicone elastomer (DE 295 18 204 U1) or Rubber, heat-resistant plastic monofilament or the like (EP 0 713 762).

In der EP 0 493 630 A1 werden monofile oder multifile Metallgarne oder solche beschrieben, bei denen Metallfäden das textile Garn umwinden. Über die Art des Umwindens ist in der EP 0 493 630 A1 nichts gesagt. Bei dem Preßpolster gemäß dem DE 295 18 304 U1 sind als Metallfäden Metallitzen, also verzwirnte Metalldrähte, aus Kupfer, Messing oder Stahl vorgesehen.EP 0 493 630 A1 describes monofilament or multifilament metal yarns or described those in which metal threads wrap the textile yarn. About the type of winding is nothing said in EP 0 493 630 A1. With the press pad according to DE 295 18 304 U1 are metal strands as metal threads, so twisted metal wires, made of copper, brass or steel provided.

Daneben ist auch vorgeschlagen, die Außenseite von siliconummantelten Metalldrähten mit geflochtenem rostfreiem Stahldraht zu bedecken. Die Herstellung solcher Fäden ist außerordentlich aufwendig, insbesondere wegen des Flechtvorgangs für den Stahldraht. Außerdem erhält man eine unebene, zerklüftete Oberfläche. Es hat sich gezeigt, daß hierdurch der Kontakt zu der Preßplatte und dem Preßgut nur punktuell und damit schlecht ist, wodurch der Wärmeübergang behindert ist.In addition, it is also suggested the outside of silicon-coated Metal wires with braided stainless Cover steel wire. The manufacture of such threads is extremely complex, especially because of the braiding process for the steel wire. You also get an uneven, rugged surface. It has been shown that hereby the contact to the press plate and the material to be pressed is only punctual and therefore bad, which causes heat transfer is disabled.

Der Erfindung liegt demnach die Aufgabe zugrunde, ein Preßpolster der eingangs genannten Art so zu gestalten, daß der Wärmeübergang verbessert wird und damit die Aufheizung des Preßgutes beschleunigt werden kann und daß es kostengünstig herstellbar ist.The invention is therefore based on the object To design press pads of the type mentioned at the beginning, that the heat transfer is improved and thus the heating of the pressed material can be accelerated and that it is inexpensive to manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Metalldraht bzw. die Metalldrähte um den zumindest teilweise gummielastisch ausgebildeten Seelenfaden gewikkelt ist bzw. sind oder daß um diesen Seelenfaden Metalldrähte verseilt sind. Solche Fäden, die einerseits aufgrund ihres gummielastischen Anteils kompressibel sind, andererseits aber außenseitig mit wenigstens einem Metalldraht versehen sind, und zwar vorzugsweise in vollständiger Abdeckung des Seelenfadens, sind vergleichsweise einfach und kostengünstig herzustellen. Sie zeichnen sich zudem durch einen konstant runden Querschnitt und eine vergleichsweise glatte Oberfläche haben, selbst wenn sie aus mehreren Metalldrähten aufgebaut sind. Hierdurch werden der Kontakt zur Preßplatte bzw. zum Preßgut und damit der Wärmeübergang wesentlich verbessert. Dabei ist es zweckmäßig, wenn der Seelenfaden in zumindest zwei Lagen von Metalldrähten umgeben ist, und zwar vorzugsweise in jeder Lage mit vollständiger Abdeckung.This object is achieved in that the metal wire or the metal wires around the at least partially rubber-elastic soul thread is or are or that around this soul thread metal wires are stranded. Such threads, on the one hand compressible due to their rubber-elastic content are, but on the outside with at least one Metal wire are provided, preferably in full Covering the soul thread are comparative easy and inexpensive to manufacture. they draw is also characterized by a constantly round cross section and have a comparatively smooth surface, even if they are made up of several metal wires. Hereby are the contact to the press plate or to the material to be pressed and so that the heat transfer is significantly improved. It is it is expedient if the soul thread in at least two layers is surrounded by metal wires, preferably in any position with full coverage.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß das gummielastische Material eine Shore A-Härte von 60 bis 75 hat. Diese Härte begünstigt das Einlagern von quer dazu verlaufenden Fäden und damit einen festen Gewebeverband. Außerdem bleibt die Restkomprimierbarkeit der erfindungsgemäßen Fäden bei dieser Härte über lange Zeit erhalten. In a further embodiment of the invention, that the rubber-elastic material has a Shore A hardness of Has 60 to 75. This hardness favors the storage of threads running transversely to it and thus a firm fabric bond. In addition, the residual compressibility remains Threads according to the invention at this hardness for a long time receive.

Für das gummielastische Material kommen alle Materialien in Frage, die gummielastische Eigenschaften haben und die in der Lage sind, den Temperaturen in den Fressen standzuhalten. Besonders eignen sich Siliconelastomere. Empfehlenswert ist ein geschäumtes gummielastisches Material, vorzugsweise mit einem spezifischen Gewicht von 0,3 bis 0,5 g/cm3.All materials that have rubber-elastic properties and are able to withstand the temperatures in the feed are suitable for the rubber-elastic material. Silicone elastomers are particularly suitable. A foamed rubber-elastic material is recommended, preferably with a specific weight of 0.3 to 0.5 g / cm 3 .

Für die Metalldrähte sollten solche Metallwerkstoffe verwendet werden, die eine hohe Wärmeleitfähigkeit haben. Hierfür bieten sich insbesondere Kupfer oder festigkeitsmodifizierte Kupferlegierungen an. Auf diese Weise kann die hohe Wärmeleitfähigkeit und der günstige Preis dieses Werkstoffs für das erfindungsgemäße Preßpolster genutzt werden. Besonders vorteilhaft ist die Verwendung von nicht geglühtem Kupfer (Kupfer-Hart), da es eine hohe Festigkeit hat. Aber auch geglühtes Kupfer (Kupfer-Weich) kommt in Frage.Such metal materials should be used for the metal wires that have a high thermal conductivity. Copper or strength-modified materials are particularly suitable for this Copper alloys. That way the high thermal conductivity and the low price of this Material used for the press pad according to the invention become. The use of is particularly advantageous not annealed copper (hard copper) as it has high strength Has. But also annealed copper (soft copper) it is an option.

Um einerseits ein sehr stabiles und steifes, andererseits aber noch hinreichend anpassungsfähiges Preßpolster zu erhalten, sollten die Fäden einen Durchmesser von wenigstens 1 mm, vorzugsweise von wenigstens 1,5 mm haben.On the one hand a very stable and rigid, on the other hand but still sufficiently adaptable press pad too the threads should have a diameter of at least 1 mm, preferably at least 1.5 mm.

Für den Seelenfaden kommen verschiedene Möglichkeiten in Frage. Der Wärmeleitung förderlich ist es, wenn der Seelenfaden als ein Metalldraht, eine Metallitze und/oder ein Metallfaden ausgebildet ist, bei dem Metalldrähte um einen Zentralfaden verseilt sind. Es kommen jedoch auch textile Materialien, wie Kunststoffmonofile oder - multifile in Frage, wobei hitzebeständige Werkstoffe, wie beispielsweise Aramide, PPS, PEK; PEEK oder dgl., zweckmäßig sind.There are various possibilities for the soul thread Question. It is conducive to heat conduction if the soul thread as a metal wire, a metal wire and / or a metal thread is formed in the metal wires around a central thread is stranded. However, it also comes textile materials, such as plastic monofilaments or - multifile in question, taking heat-resistant materials such as for example aramids, PPS, PEK; PEEK or the like, appropriate are.

In an sich bekannter Weise sollte der Seelenfaden aus einem Zentralfaden und einer diesen umgebenden Hülle aus dem gummielastischen Werkstoff bestehen, um dem Faden mehr Festigkeit zu geben. Dabei kann der Zentralfaden als Kunststoffmonofil oder -multifil oder als Metalldraht, Metallitze oder Metallfaden ausgebildet sein, bei dem Metalldrähte um einen Kernfaden verseilt sind.In a manner known per se, the soul thread should consist of one Central thread and a sheath surrounding it the rubber-elastic material consist of the thread to give more strength. The central thread can be used as Plastic monofilament or multifilament or as metal wire, Metal wire or metal thread can be formed in the metal wires are stranded around a core thread.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die verseilten Metalldrähte teilweise S- und teilweise Z-förmig verseilt sind, wobei dies zweckmäßigerweise abwechselnd geschieht. Hierdurch kann ein

Die vorstehend beschriebenen Fäden können mit Metallfäden kombiniert werden, welche keinen gummielastischen Anteil haben, sondern bei denen ein Zentralfaden aus Metall oder Kunststoff von wenigstens einem Metalldraht umwickelt ist. Alternativ dazu können um den Zentralfaden Metalldrähte verseilt sein. In beiden Fällen macht man von den schon oben erwähnten Vorteilen Gebrauch, daß eine sehr glatte Oberfläche und damit ein guter Wärmeübergang erzielt wird. Solche Metallfäden können vorgesehen sein, wenn der Wärmeübergang durch die oben beschriebenen Fäden mit gummielastischem Anteil nicht ausreicht. The threads described above can be made with metal threads be combined, which have no rubber-elastic portion but have a central thread made of metal or Plastic wrapped by at least one metal wire is. Alternatively, metal wires can be around the central thread be stranded. In both cases one makes of the already mentioned advantages use that a very smooth surface and thus good heat transfer achieved becomes. Such metal threads can be provided if the heat transfer through the threads described above with rubber-elastic content is not sufficient.

Figur 1 zeigt einen Faden 1 für ein hier nicht näher dargestelltes Preßpolster. Er ist für ein Gewebe vorgesehen, das beispielsweise in Leinwand- oder Köper-Bindung gewebt ist, und zwar als Querfaden. Solche Gewebe kommen als Preßpolster oder als Grundgewebe für Preßpolster zum Einsatz.Figure 1 shows a thread 1 for a not shown here Press pad. It is intended for a fabric for example woven in a plain or twill weave is, as a transverse thread. Such tissues come as Press pads or as a base fabric for press pads.

Der Faden 1 hat einen Elastomerkern 2 aus einem Siliconelastomer, der - was hier nicht näher dargestellt ist - einen Zentralfaden umgibt, der beliebig aufgebaut sein kann, beispielsweise als Metall- oder Kunststoffaden.The thread 1 has an elastomer core 2 made of a silicone elastomer, the - which is not shown here - surrounds a central thread, which can be constructed arbitrarily can, for example as a metal or plastic thread.

Um den Elastomerkern 2 sind sechs Metalldrähte - beispielhaft mit 3 bezeichnet - verseilt. Nach Abschluß des Verseilungsvorgangs ist der Elastomerkern 2 vollflächig von den Metall-drähten 3 umgeben, die damit eine lückenlose Metallumhüllung bilden. Der Faden 1 ist deshalb zur Verbesserung des Wärmedurchgangs durch ein damit hergestelltes Preßpolster geeignet, sei es, daß Fäden 1 allein den metallischen Anteil im Preßpolster bilden, sei es zusätzlich zu Metallängsfäden oder sei es, daß auch die Längsfäden in gleicher Weise ausgebildet sind wie der Faden 1.Around the elastomer core 2 are six metal wires - exemplary marked with 3 - stranded. After completing the Stranding process is the full area of the elastomer core 2 surrounded by the metal wires 3, making it a complete Form metal cladding. The thread 1 is therefore for Improvement of the heat transfer through a manufactured with it Press pad suitable, be it that threads 1 alone form the metallic part in the press cushion, be it additional to longitudinal metal threads or be it that the Longitudinal threads are formed in the same way as the thread 1.

Figur 2 zeigt einen Faden 4, der als Ersatz für oder in Kombination mit dem Faden 1 gemäß Figur 1 in einem Preßpolster Verwendung finden kann. Er hat ebenfalls einen Elastomerkern 5 aus einen Siliconelastomer, der - was hier gleichfalls nicht näher dargestellt ist - einen Zentralfaden umgibt, der in gleicher Weise aufgebaut sein kann wie bei dem Faden 1 gemäß Figur 1.Figure 2 shows a thread 4, which as a replacement for or in Combination with the thread 1 according to FIG. 1 in a press cushion Can be used. He also has one Elastomer core 5 made of a silicone elastomer, which - what is also not shown here - a central thread surrounds that be constructed in the same way can, as with the thread 1 according to FIG. 1.

Um den Elastomerkern 5 ist ein Metalldraht 6 gewickelt, und zwar derart, daß er den Elastomerkern 5 vollflächig umgibt und damit eine lückenlose Metallumhüllung gebildet wird. Es ist zweckmäßig, daß um den Metalldraht 6 ein weiterer Metalldraht in umgekehrter Richtung gewickelt wird, so daß sich dann eine zweilagige Metallumhüllung ergibt. Dies stellt sicher, daß auch in Biegungen einen vollständige Umhüllung des Elastomerkerns 5 gewährleistet ist.A metal wire 6 is wound around the elastomer core 5, in such a way that it covers the entire area of the elastomer core 5 surrounds and thus formed a gapless metal sheath becomes. It is appropriate that around the metal wire 6 a another metal wire wound in the opposite direction is, so that there is then a two-layer metal coating results. This ensures that even in bends one ensures complete encapsulation of the elastomer core 5 is.
