Die
Es ist die Aufgabe der vorliegenden Erfindung, ein Band für eine Maschine zur Herstellung von Bahnmaterial sowie ein Verfahren zur Herstellung eines derartigen Bandes vorzusehen, mit welchem in einfacher Weise ein die in Presssektion auftretenden Anforderungen erfüllendes Band realisierbar ist.It is the object of the present invention to provide a belt for a machine for the production of web material and a method for producing such a belt, with which a simple in. The in Pressing section occurring requirements fulfilling tape is feasible.
Gemäß der vorliegenden Erfindung wird diese Aufgabe gelöst durch ein Band für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, umfassend eine Tragestruktur und wenigstens eine Lage aus Schaumstoffmaterial. Erfindungsgemäß ist dabei weiter vorgesehen, dass die Tragestruktur in das Schaumstoffmaterial eingeschäumt ist.According to the present invention, this object is achieved by a belt for a machine for producing web material, in particular paper or cardboard, comprising a support structure and at least one layer of foam material. According to the invention it is further provided that the support structure is foamed into the foam material.
Bei dem erfindungsgemäßen Band ist also die Tragestruktur vollständig in das Schaumstoffmaterial eingeschäumt, also eingebettet. Dadurch wird eine einfache Herstellbarkeit ermöglicht, da das Schaumstoffmaterial einerseits und die Tragestruktur andererseits nicht in zusätzlichen Arbeitsgängen miteinander zu verbinden sind. Andererseits kann insbesondere durch die Auswahl des Schaumstoffmaterials den in Wechselwirkung mit dem zu fertigenden Bahnmaterial auftretenden Anforderungen optimiert Rechnung getragen werden, während durch die Auswahl der Tragestruktur den in Maschinenlängsrichtung und in Maschinenquerrichtung auftretenden mechanischen Belastungen Rechnung getragen werden kann.In the band according to the invention, therefore, the support structure is completely foamed into the foam material, that is embedded. This allows easy manufacturability, since the foam material on the one hand and the support structure on the other hand are not to be connected in additional operations with each other. On the other hand, in particular by the selection of the foam material, the requirements arising in interaction with the web material to be produced can be optimally taken into account, while the selection of the carrying structure can take into account the mechanical loads occurring in the machine longitudinal direction and in the cross machine direction.
Das eingesetzte Schaumstoffmaterial ist vorzugsweise offenzellig. Insbesondere kann thermoplastisches Polymermaterial, vorzugsweise Polyurethanmaterial, als Schaumstoffmaterial vorgesehen sein. Das Schaumstoffmaterial kann alternativ oder zusätzlich duroplastisches Polymermaterial, vorzugsweise Melamin-Formaldehyd, umfassen.The foam material used is preferably open-celled. In particular, thermoplastic polymer material, preferably polyurethane material, may be provided as a foam material. The foam material may alternatively or additionally comprise thermosetting polymeric material, preferably melamine-formaldehyde.
Die Tragestruktur kann beispielsweise ausgebildet sein als:
- Fasermaterial,
- Gewebe,
- Gelege oder
- Kettengewirk.
- Fiber material,
- Tissue,
- Clutch or
- Warp knit.
Weiter kann zur Anpassung der Oberflächeneigenschaften des erfindungsgemäßen Bandes an die in einem Herstellungsvorgang auftretenden Anforderungen vorgesehen sein, dass das Schaumstoffmaterial an wenigstens einer Seite mit Vlies- oder Filzmaterial verbunden ist.Furthermore, in order to adapt the surface properties of the strip according to the invention to the requirements occurring in a production process, it may be provided that the foam material is connected to nonwoven or felt material on at least one side.
Das Schaumstoffmaterial kann mit der darin eingeschäumten Tragestruktur in einem Filmextrusionsverfahren hergestellt werden.The foam material can be made with the support structure foamed therein in a film extrusion process.
Gemäß einem weiteren Aspekt der Erfindung kann bei einem gattungsgemäß aufgebauten Band vorgesehen sein, dass das Schaumstoffmaterial offenporig ist und auf einer damit verbundenen Tragestruktur aufliegt.According to a further aspect of the invention may be provided in a generic constructed band, that the foam material is open-pored and rests on a support structure connected thereto.
Auch durch das voneinander getrennte Herstellen des Schaumstoffmaterials einerseits und der Tragestruktur andererseits und darauf folgend das Verbinden dieser beiden Lagen wird insbesondere aufgrund des Einsatzes des Schaumstoffmaterials der gesamte Herstellungsvorgang im Vergleich zum Einsatz einer Auflage aus Vliesmaterial vereinfacht.Also due to the separate production of the foam material on the one hand and the support structure on the other hand and then connecting these two layers, the entire manufacturing process is simplified in comparison with the use of a pad of nonwoven material in particular due to the use of the foam material.
Gemäß einem weiteren Aspekt betrifft die vorliegende Erfindung ein Verfahren zur Herstellung eines Bands für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Papier oder Karton, bei welchem Verfahren eine Tragestruktur in einem Extrusionsverfahren mit wenigstens einer Lage aus Schaumstoffmaterial umschäumt wird.According to a further aspect, the present invention relates to a method for producing a belt for a machine for producing sheet material, in particular paper or cardboard, in which method a support structure is foamed in an extrusion process with at least one layer of foam material.
Die vorliegende Erfindung wird nachfolgend mit Bezug auf die beiliegende
Das in der
Die Tragestruktur 12 wird in einem Filmextrusionsverfahren durch einen Extrusionskopf hindurchgeführt und dabei mit offenzelligem Schaumstoffmaterial 18 umschäumt. Auf diese Art und Weise ist das Schaumstoffmaterial 18 die Tragestruktur vollständig einbettend an dieser vorgesehen und sehr stabil gehalten. Durch diesen Verbund werden insbesondere auch bei Einsatz eines Geleges die einzelnen Gelegefäden stabil bezüglich einander arretiert. Die an dem Schaumstoffmaterial 18 gebildeten Oberflächen können beispielsweise eine Bandmaterialkontaktoberfläche 20 sowie eine Maschinenkontaktoberfläche 22 bilden.The
Das Schaumstoffmaterial 18 kann beispielsweise thermoplastisches Polymermaterial, wie z. B. Polyurethanmaterial, umfassen und weist aufgrund seiner offenzelligen Struktur eine hervorragende Wasser abführende Eigenschaft auf. Durch die Einstellung der Größe der im Schaumstoffmaterial 18 vorhandenen Zellen, der Auswahl des Schaumstoffmaterials an sich und dessen Dimensionierung wird es möglich, den im Bereich einer Presssektion auftretenden Anforderungen hinsichtlich der Entfeuchtungseigenschaften, hinsichtlich der Abrasionseigenschaften bzw. auch den druckelastischen Eigenschaften optimiert Rechnung zu tragen. Die mechanische Stabilität in Längs- und Querrichtung wird durch die Tragestruktur 12 gewährleistet. Diese kann, wie bereits erwähnt, beispielsweise als Gelege ausgebildet sein. Selbstverständlich können auch anders strukturierte Tragestrukturen, beispielsweise ein Gewebe, ein Filz- oder Vliesmaterial oder ein netzartiges Material zum Einsatz kommen. Auch ist der Einsatz von Fasermaterial, also ein mehr oder weniger lose verteiltes, langfaseriges Material als Tragestruktur möglich, wobei die einzelnen Fasern dann primär durch das diese umgebende Schaumstoffmaterial 18 zu einem Verbund zusammengehalten werden, der in Längsrichtung und auch in Querrichtung die auftretenden Kräfte aufnehmen kann.The
Es ist weiterhin möglich, an einer oder an beiden Seiten bezüglich der Tragestruktur 12 mehrere Lagen von Schaumstoffmaterial vorzusehen, wobei sich diese Lagen hinsichtlich ihrer strukturellen bzw. materiellen Eigenschaften unterscheiden können. Weiterhin ist es alternativ oder zusätzlich möglich, an zumindest einer Seite eine Lage von Vlies- oder Filzmaterial vorzusehen, um beispielsweise durch Vernadeln mit der darunter liegenden Schaumstoffmateriallage zu verbinden. Auch dadurch kann eine Anpassung der Eigenschaften eines derartigen Bandes 10 an die in einer Papiermaschine auftretenden Anforderungen erfolgen.It is also possible to provide on one or both sides with respect to the support structure 12 a plurality of layers of foam material, which layers may differ in their structural or physical properties. Furthermore, it is alternatively or additionally possible to provide a layer of nonwoven or felt material on at least one side in order to connect, for example by needling, to the underlying foam material layer. This also makes it possible to adapt the properties of such a strip 10 to the requirements occurring in a paper machine.
Bei einer alternativen Ausgestaltungsform kann vorgesehen sein, dass das Schaumstoffmaterial 18 die Tragestruktur 12 nicht einbettet, sondern separat hergestellt wird und auf die Tragestruktur 12 aufgelegt und nachfolgend damit verbunden wird, beispielsweise materialschlüssig oder durch Vernadeln oder dgl. Auch dadurch wird aufgrund des Ersatzes von bisher eingesetztem Vliesmaterial oder Filzmaterial durch das Schaumstoffmaterial eine einfachere Herstellbarkeit gewährleistet.In an alternative embodiment, it may be provided that the
