Abstract

Es wird ein Kalander (1) angegeben mit mehreren in einem Walzenstapel angeordneten Walzen (2-6) und einer Sensoranordnung (25), die eine Schwingung mindestens einer Walze (5) erfaßt.A calender (1) is specified with several in one Roll stack arranged rollers (2-6) and a Sensor arrangement (25), the vibration at least a roller (5) detected.

Man möchte eine Barring-Bildung vermindern.You want to reduce a barring education.

Hierzu weist mindestens eine Walze (3, 4) eine steuerbare Magnetfeld-Erzeugungseinrichtung (21, 23) auf, die ein auf eine andere Walze (4, 3) einwirkendes Magnetfeld in Abhängigkeit von Signalen der Sensoranordnung (25) erzeugt.

Figure 00000001
For this purpose, at least one roller (3, 4) has a controllable magnetic field generating device (21, 23) which generates a magnetic field acting on another roller (4, 3) as a function of signals of the sensor arrangement (25).
