Abstract

Die Erfindung betrifft eine Vorrichtung zum direkten oder indirekten Auftragen eines flüssigen oder pastösen Mediums auf eine zwar fertig gebildete, aber noch nasse Materialbahn umfassend: eine Walze, ein Auftragswerk und wenigstens ein die Materialbahn tragendes Siebband, welches zwischen dem Auftragswerk und der Materialbahn angeordnet ist, wobei das Auftragsmedium im Umschlingungsbereich der Walze mit der Materialbahn in Kontakt tritt.The invention relates to a device for direct or indirect application of a liquid or pasty medium a material web that has been formed but is still wet comprising: a roller, an applicator and at least one die Web belt carrying material web, which between the Commissioned work and the material web is arranged, the Application medium in the wrapping area of the roller with the Material web comes into contact.

Weiterhin betrifft die Erfindung ein Verfahren zum Auftragen eines flüssigen oder pastösen Auftragsmediums auf eine laufende Materialbahn aus Papier oder Karton, wobei in der Naßpartie einer Papier- oder Kartonmaschine eine Materialbahn gebildet wird, die Materialbahn während des Auftragens des Auftragsmediums mittels eines laufenden, endlosen, vorzugsweise luftdurchlässigen Bandes geführt wird und das Auftragsmedium von einer, sich in Bahnlaufrichtung bewegenden Oberfläche, auf die noch nasse Materialbahn übertragen wird.The invention further relates to a method for application a liquid or pasty application medium on a running material web of paper or cardboard, whereby in the Wet section of a paper or board machine a web of material is formed, the material web during the application of the Order medium by means of a running, endless, preferably air-permeable tape and that Application medium from a moving in the direction of web travel Surface to which the wet web of material is transferred.

Das Verfahren zeichnet sich dadurch aus, daß das Auftragsmedium von mindestens einem laufenden, endlosen, luftdurchlässigen Transferband auf die Materialbahn übertragen wird.
