Abstract

Gemäß einem ersten Aspekt betrifft die Erfindung eine Pressanordnung zur Entwässerung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn in einer Maschine zur Herstellung derselben mit zumindest einem, von zwei Presswalzen gebildeten Pressspalt, durch den neben der Faserstoffbahn beidseitig je ein Pressfilz läuft. Dabei soll eine sichere Führung der Faserstoffbahn beim und nach dem Wegführen des oberen Pressfilzes dadurch erreicht werden, dass nach dem Pressspalt beide Pressfilze gemeinsam mit der Faserstoffbahn eine Leitwalze des unteren Pressfilzes teilweise umschlingen und zu einem, mit dem unteren Pressfilz in Kontakt stehenden Saugkasten laufen, wobei der obere Pressfilz im Bereich des Saugkastens von der Faserstoffbahn weggeführt wird. Gemäß einem zweiten Aspekt betrifft die Erfindung ein stationäres Saugelement zum Ansaugen einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn an ein luftdurchlässiges, endlos umlaufendes Band einer Maschine zur Herstellung und/oder Veredelung der Faserstoffbahn, wobei das Band über eine Kontaktfläche des Saugelementes gleitet und die Kontaktfläche mehrere Saugöffnungen besitzt. Dabei soll eine gute Haftung der Faserstoffbahn am Band insbesondere auch bei einer notwendigen Umlenkung des Bandes dadurch erreicht werden, dass die Kontaktfläche in Bahnlaufrichtung konvex gekrümmt läuft.
