Abstract

Ein Kalander besitzt mindestens einen Walzenstapel (1), dessen Oberwalze (2) und Unterwalze (3) je als Durchbiegungsausgleichswalze ausgebildet sind. Der Walzenmantel (15, 15a) der Oberwalze (2) und/oder der Unterwalze (3) trägt einen Bezug aus einem elastischen Kunststoff oder besteht vollständig aus elastischem Kunststoff und ist biegeweich ausgelegt. Die jeweils benachbarte Mittelwalze ist eine harte Walze (4, 13). Dies führt zu verbesserten Einstellmöglichkeiten zur Erzielung gewünschter Parameter der Papierbahn.

Figure 00000001
A calender has at least one roll stack (1), the upper roll (2) and lower roll (3) of which are each designed as a deflection compensation roll. The roller jacket (15, 15a) of the top roller (2) and / or the bottom roller (3) is covered with an elastic plastic or consists entirely of elastic plastic and is designed to be flexible. The adjacent center roll is a hard roll (4, 13). This leads to improved setting options for achieving the desired parameters of the paper web.
