摘要

The electromagnetic roller arrangement has two magnetic rollers (1) with a cylindrical or a pipe shaped roller base (2), where a coaxial supporting tube (3) is arranged on the roller base. The supporting tube has a non-ferromagnetic material. The magnetic rollers are partially or totally encased on both sides of levels of a roller axis on total working width of magnetic yokes. The yokes have a ferromagnetic material, forming a shell shape at periphery. The material thickness of the yokes, decreases from the working level of a rolling gap (13) in the peripheral direction of the rollers.
