Abstract
In einer Papiermaschine zur Herstellung einer Materialbahn (10) wie einer Papier- oder Kartonbahn wird die herzustellende Materialbahn (10) auf der Oberfläche eines Transfermittel (24) zu einer Abnahmestelle (30) überführt, in deren Bereich ein eine zumindest im wesentlichen offene Oberfläche aufweisendes, vorzugsweise luftdurchlässiges Band (32) über eine Abnahmewalze (34) oder dergleichen geführt ist und die Materialbahn (10) von der Oberfläche des Transfermittels (24) abnimmt. An der Abnahmestelle (30) ist ein in Bahnlaufrichtung (L) verlängerter Preßspalt (36) gebildet, in dessen Bereich die der Materialbahn (10) zugewandte Oberfläche des Transfermittels (24) sowohl unter Ausbildung einer zumindest im wesentlichen konkaven Mulde (38) umgelenkt als auch durch eine gezielt im Bereich dieser Umlenkung erzeugte Preßkraft gegen die Abnahmewalze (34) gepreßt ist, um dadurch die Abnahme der Materialbahn (10) von der Transfermitteloberfläche zu unterstützen. In a paper machine for producing a material web (10) such as a paper or cardboard web, the material web (10) to be produced is transferred on the surface of a transfer means (24) to a removal point (30), in the area of which there is an at least substantially open surface , preferably air-permeable belt (32) is guided over a removal roller (34) or the like and the material web (10) is removed from the surface of the transfer means (24). At the take-off point (30) an elongated press nip (36) is formed, in the area of which the surface of the transfer means (24) facing the material web (10) is redirected to form an at least substantially concave trough (38) is also pressed against the take-off roller (34) by a pressing force specifically generated in the region of this deflection, in order thereby to support the removal of the material web (10) from the transfer medium surface.
