Abstract

The present invention relates to a roller device for treating flat material in particular for smoothing foils (F*) or plates comprising a first roller unit (1) and a second roller unit (2) wherein each roller unit (1 2) comprises: at least one drive motor having a motor moment of inertia ; a roller (10 20) having a roller moment of inertia ; and at least one gear unit for kinematically coupling the roller (10 20) and the at least one drive motor at a transmission ratio between the at least one drive motor and the roller (10 20) wherein the roller (20) in the second roller unit (2) can be rotated in the opposite direction to that of the roller (10) in the first roller unit (1) and wherein a first roller gap (40) through which the flat material is guided is formed between the roller (10) of the first roller unit (1) and the roller (20) of the second roller unit (2). According to the invention the roller device is characterised in that for at least one of the first and the second roller units (1 2) the moment of inertia speed ratio between the at least one drive motor and the roller (10 20) is = 6 and the transmission ratio 1 < = 40 is selected wherein the following applies: (formula I) where speed of the drive motor and = speed of the roller (10 20). The invention further relates to a smoothing device for smoothing foils or plates as well as a method for producing flat material in particular foils or plates.
