Description
Die Patentanmeldung P 22 30 220.1-16 betrifft ein Preßpolster für eine Heizpresse zum Aufpressen von mit härtbaren Kunstharzen getränkten Trägerbahnen CKder härtbaren Kunststoffolien auf die Oberfläche von Holzwerkstoffplatten, welches Preßpolster zwischen Preßwerkzeug und Preßblech eingelegt ist und als komprimierbares Metallfaservlies, welches nach Druckentlastung zumindest annähernd wieder die ursprüngliche Preßpolsterdicke annimmt, ausgebildet ist.The patent application P 22 30 220.1-16 relates to a press pad for a heating press for pressing on with curable synthetic resins impregnated carrier webs of the curable plastic films on the surface of Wood-based panels, which press pad is inserted between the press tool and press plate and as compressible metal fiber fleece, which after pressure relief at least approximately returns to the original Press pad thickness assumes is formed.
Dem nicht zum Stande der Technik gehörenden Gegenstand der Hauptanmeldung liegt als Aufgabe zugrunde,
das bekannte Metallfaservlies als Preßpolster so einzusetzen, daß es zwar den Wärmedurchgang von
der Heizpresse zum Preßblech unter Druck begünstigt, $0 daß die Heizpresse auf niedrigere Temperaturen erhitzt
werden kann, andererseits aber nach dem öffnen der Presse den Wärmedurchgang wieder so reduziert,
daß das Preßblech abkühlt, so daß ein vorzeitiges Aushärten der abgelegten Kunstharzfilme beim erneuten
Beschicken vermieden wird. Nach dem Schließen der Presse soll dann die Temperatur des Preßbleches aber
wieder schnell ansteigen. Die Lösung dieser Aufgabe gelingt gemäß Patentanmeldung P 22 30220.1-16 dadurch,
daß das Metallfaservlies allseitig offen Luftzu- und -austritt ermöglichend ausgebildet ist
Im Rahmen der Aufgabenstellung der Patentanmeldung P 22 30 220.1-16 und in Weiterbildung der Lösung
dieser Aufgabe wurde nun gefunden, daß man die Standzeit (Gebrauchsdauer) des Metallfaservlieses wesentlich
verbessern kann, wenn erfindungsgemäß das Metallfaservlies ein- oder beidseitig oder als MittellageThe object of the main application, which does not belong to the prior art, is based on the task of using the known metal fiber fleece as a press pad in such a way that, although it promotes the passage of heat from the heating press to the press plate under pressure, the heating press can be heated to lower temperatures, but on the other hand After opening the press, the heat transfer is reduced again so that the press plate cools down, so that premature hardening of the synthetic resin films deposited is avoided when they are loaded again. After the press is closed, the temperature of the press plate should rise again quickly. The solution to this problem is achieved according to patent application P 22 30220.1-16 in that the metal fiber fleece is designed to allow air inlet and outlet to be open on all sides
In the context of the task of patent application P 22 30 220.1-16 and in a further development of the solution to this problem, it has now been found that the service life (service life) of the metal fiber fleece can be significantly improved if, according to the invention, the metal fiber fleece is one or both sides or as a central layer
ίο ein mit ihm verbundenes Geflecht aufweistίο has a mesh connected to it
Unter dem Ausdruck Geflecht sollen dabei alle Gebilde verstanden werden, die aus Fasern flächig hergestellt werden können, ausgenommen Vliese. Ein typisches Beispiel für ein Geflecht ist ein Gewebe.The term braid should be understood to mean all structures that are made of two-dimensional fibers with the exception of nonwovens. A typical example of a braid is a woven fabric.
Vorzugsweise wird als Faser zur Herstellung des Geflechtes eine Metallfaser oder eine Glasfaser verwendet Im Falle der Verwendung einer Metallfaser braucht diese nicht aus dem gleichen Werkstoff zu bestehen wie das Metallfaservlies.The preferred fiber used to manufacture the braid a metal fiber or a glass fiber is used In the case of using a metal fiber it does not need to be made of the same material as the metal fiber fleece.
Das Geflecht is' vorzugsweise dünn und engmaschig, soll elastisch sein und sich so dem Metallfaservlies anschmiegen. Durch die Verbindung des Vlieses oder der Vlieslagen mit dem Geflecht oder den Geflechten wird ein Verschieben des Vlieses oder der Vlieslagen gegenüber dem Geflecht oder den Geflechten verhindert. Der Verbund kann dadurch hergestellt werden, daß man das Geflecht oder die Geflechte mit dem Vlies oder den Vlieslagen durch einfache oder mehrfache Nadelung oder durch Steppnähte miteinander verbindet. The braid is preferably thin and close-meshed, should be elastic and thus cling to the metal fiber fleece. By connecting the fleece or fleece layers with the braid or braids a displacement of the fleece or fleece layers with respect to the braid or braids is prevented. The composite can be produced in that the braid or braids with the fleece or the fleece layers are connected to one another by single or multiple needling or by quilting seams.
In den Abbildungen ist ein Ausführungsbeispiel eines erfindungsgemäßen Metallfaservlieses vereinfacht dargestellt. Dabei sind die Steppnähte bzw. die Verbindung durch Nadelung nicht gezeichnet.In the figures, one embodiment is one Metal fiber fleece according to the invention shown in simplified form. Here are the stitching or the connection not drawn by needling.
A b b. 1 zeigt ein Preßpolster, welches aus drei Lagen (3. 4 und S) eines Metallfaservlieses besteht, wobei die Vlieslagen in ihrer bevorzugten Faserrichtung einen Winkel gegeneinander bilden. Dieses Paket aus mehreren Vlieslagen ist oben mit einem Metallgeflecht (1) und unten mit einem Metallgeflecht (2) abgedeckt und mit dem Vlies durch Nadelung verbunden;A b b. 1 shows a press pad which consists of three layers (3.4 and S) of a metal fiber fleece, the Fleece layers form an angle to one another in their preferred fiber direction. This package of several Fleece layers are covered at the top with a metal mesh (1) and at the bottom with a metal mesh (2) and connected to the fleece by needling;
A b b. 2 zeigt ein Ausführungsbeispiel eines erfindungsgemäßen Preßpolsters, bei dem das Metallgeflecht (6) in der Mitte des Polsters angeordnet ist, wobei oberhalb und unterhalb des Geflechtes jeweils zwei Lagen Metallfaservlies (4 und 5) angeordnet sind, wobei die bevorzugten Richtungen der Fasern im Vlies einen Winkel zueinander bilden.A b b. 2 shows an embodiment of a press pad according to the invention, in which the metal mesh (6) is arranged in the middle of the pad, with two each above and below the braid Layers of metal fiber fleece (4 and 5) are arranged, with the preferred directions of the fibers in the fleece form an angle to each other.
