Embodiment Construction
[0034] figure 1 The smoothing device shown in an extremely schematic sectional view comprises a total of three rolling units 1 , 2 , 3 which each comprise a motor with a moment of inertia J M1,M2,M3 drive motor with roll moment of inertia J W1,W2,W3 The temperature-regulated rolls 10, 20, 30 and the transmission for the transmission ratio i between the drive motor and the rolls 10, 20, 30 MW1,MW2,MW3 The respective roll 10 , 20 , 30 is kinematically coupled to the associated drive motor. In this case, the rolls 20 of the second rolling unit 2 can rotate counter to the rolls 10 of the first rolling unit 1 . Likewise, the rolls 30 of the third rolling unit 3 can rotate counter to the rolls 10 of the first rolling unit. A first roll gap 40 is formed between the rolls 10 of the first rolling unit 1 and the rolls 20 of the second rolling unit 2 . Furthermore, the rolls 10 of the first rolling unit 1 and the rolls 30 of the third rolling unit 3 form a second nip 50, wherein the ...

The present invention relates to a roller device for treating a 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 J; - a roller (10, 20) having a roller moment of inertia J; and - at least one gear unit for kinematically coupling the roller (10, 20) and the at least one drive motor at a transmission ratio i 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 M<=6 and the transmission ratio 1<=40 is selected, wherein the following applies: (formula I) where n=speed of the drive motor, and n=speed of the roller (10, 20). The invention further relates to a smoothing device for smoothing the foils or the plates, as well as a method for producing the flat material, in particular the foils or the plates.
Description
technical field [0001] The invention relates to a rolling device for processing planar materials, in particular for smoothing films or plates, comprising a first rolling unit and a second rolling unit, wherein each rolling unit comprises a Motor moment of inertia J M at least one drive motor with a roll moment of inertia J W The roll and at least one transmission device, which is used to drive the transmission ratio i between the at least one drive motor and the roll MW Kinematically coupling the rolls to the at least one drive motor, wherein the rolls of the second rolling unit are rotatable against the rolls of the first rolling unit, and wherein the rolls of the first rolling unit are in contact with the second Between the rolls of the rolling unit a first roll gap is formed, through which the planar material is guided. Furthermore, the invention relates to a method for producing a planar material, in particular a film or a plate. Background technique [0002] Product...
