Method for absorption of oscillations in nip between two rollers in machine, involves reeving viscous fluid in gap between two lamellae, where lamella is connected with bearing of two rollers

摘要

The method involves reeving a viscous fluid in a gap between two lamellae. A lamella (2,7) is connected with a bearing of two rollers and another lamella (3,8) is connected stationary with other roller. The liquid flows through the gap. The liquid is maintained at a low tmperature. The fluid is a magnetorheological fluid and viscosity is adjusted by altering an electric or a magnetic field. An independent claim is also included for a device for the absorption of oscillations in a nip between two rollers in a machine for the production or conditioning of a material web, particularly a paper or a cardboard.
