Abstract

Frequency of a rotating roller sleeve's (1) passage through a pressing gap lies below the inherent frequency of a fixed single-piece axle (2) in a direction (6) of pressing. While ensuring required stability under load and vibrational stability, the weight of the fixed single-piece axle is minimized by the fact that the inherent frequency of this axle crosswise to the direction of pressing lies below the inherent frequent of this axle in the direction of pressing. An independent claim is also included for a pressing system with a pressing roller.
