Abstract (en)

To satinize the surfaces of a web, and especially of paper, the web is passed through a nip formed by a roller with an elastic cladding of a plastics with a fiber reinforcement and a counter roller. The reinforcement fibers at the roller cladding are aligned according to the required surface finish, using glass or carbon fibers. The alignment and the thickness of the reinforcement fibers are set according to the required surface finish. The fiber dia. matches the dia. of the paper fibers in the web. An Independent claim is included for a roller, to satinize the paper web surface, with an even and inhomogenous hardness distribution over its surface (7). Preferred Features: The neighboring and adjacent roller surface zones (4) have a different hardness, where the dimensions of the separate hard surfaces (4) match the dia. of a paper fiber. The roller has a surface roughness Ra 0.1 mu m. The roller cladding (3) has reinforcement fibers (4) embedded in the plastics, where the fibers (4) are aligned radially by 90% at the surface, with a different hardness from the plastics material. The fibers (4) are bristles or radially aligned roving sections (6).

Abstract (de)

Es wird ein Verfahren zum Satinieren einer Materialbahn angegeben, insbesondere einer Papierbahn, bei dem die Materialbahn durch mindestens einen Nip geführt wird, der durch eine Walze (1) mit einem elastischen Bezug (3) aus einem mit Fasern oder entsprechenden Füllstoffen verstärktem Kunststoff und einer Gegenwalze gebildet ist. Ferner wird eine hierfür geeignete Walze angegeben. Beim Satinieren möchte man gezielt einen Einfluß auf die Transparenz der Materialbahn nehmen können. Hierzu wird in Abhängigkeit vom gewünschten Satinageergebnis die Hauptrichtung der Fasern (4) im Bezug (3) ausgewählt wird. Zur Erzielung einer hohen Transparenz weist die Walze eine über die gesamte Oberfläche (7) gleichmäßige inhomogene Härteverteilung auf. <IMAGE>
