Abstract

Es wird eine Vorrichtung zur Behandlung einer Materialbahn, insbesondere zur Beeinflussung von Glanz und/oder Glätte einer Papier- oder Kartonbahn oder zur Entwässerung einer Papier- oder Faservliesbahn beschrieben. Diese Vorrichtung umfasst wenigstens einen Breitnip (14), der zwischen einer Breitnipeinheit (10) mit wenigstens einem in Bahnlaufrichtung (L) verlängerten Breitnipschuh (18) sowie einem über den Breitnipschuh (18) zugeführten umlaufenden flexiblen Band (20) und einer komplementären Gegeneinheit (12) gebildet ist. Die Breitnipeinheit (10) umfasst überdies eine zwischen dem Breitnipschuh (18) und dem umlaufenden flexiblen Band (20) angeordnete, aus biegsamem und/oder elastischem Material bestehende Platte (22) sowie mehrere zwischen dieser und dem Breitnipschuh (18) vorgesehene, in Bahnlaufrichtung (L) aufeinander folgende Aktuatoren (24), über die die sich in Bahnlaufrichtung (L) ergebende Nipbreite durch eine entsprechende Beaufschlagung der biegsamen bzw. elastischen Platte (22) variabel einstellbar ist. Dabei ist eine zumindest einen Aktuator (24) umfassende einlaufseitige Aktuatoranordnung (241) und eine zumindest einen Aktuator (24) umfassende auslaufseitige Aktuatoranordnung (242) vorgesehen, die in Bahnlaufrichtung betrachtet jeweils räumlich von den dazwischen liegenden mittleren Aktuatoren (24) getrennt sind.

The invention relates to a device for treating a material web, in particular for influencing the gloss and / or smoothness of a paper or board web or for dewatering a paper or nonwoven web. This device comprises at least one wide nip (14) which is connected between a broad nip unit (10) with at least one broad nip shoe (18) extended in the web running direction (L) and a circumferential flexible belt (20) fed via the wide nip shoe (18) and a complementary counter unit (10). 12) is formed. The Breitnipeinheit (10) further comprises a between the Breitnipschuh (18) and the circulating flexible band (20) arranged, consisting of flexible and / or elastic material plate (22) and a plurality between this and the Breitnipschuh (18) provided in the web running direction (L) successive actuators (24) over which the nip width resulting in the web running direction (L) can be variably adjusted by a corresponding loading of the flexible or elastic plate (22). In this case, an at least one actuator (24) comprehensive inlet-side actuator assembly (24 1 ) and at least one actuator (24) comprehensive outlet side actuator assembly (24 2 ) is provided, each viewed spatially separated in the web running direction of the intermediate central actuators (24) ,
