patent summary for: "rolling device for handling flat material, in particular for flattening films and sheets, flattening device and method for producing flat material, in particular films and sheets". The present invention relates to a rolling device for treating sheet material, in particular for the flattening of films (f *) or sheets, comprising a first bearing unit 1 and a second bearing unit 2, each bearing unit (1, 2) comprising: - at least one drive motor with a motor inertia moment jm, - a roller (10, 20) with a roller inertia moment jw, - at least one gear for kinematic coupling of the roller (10, 20) to at least one drive motor with transmission ratio imw between the at least one drive motor and the roller (10, 20) with the roller (20) of the second drive unit. The bearing (2) can be rotated in the opposite direction to the roller (10) of the first bearing unit (1) and a gap (40) is formed between the roller (10) of the first bearing unit (1) and the roller. (20) of the second bearing unit (20) by which the sheet material (f) is guided. According to the invention, the rolling device is characterized by at least one of the first and second rolling units (1, 2), the moment of inertia / speed ratio between the at least one drive motor and the roller (10). , 20) mmw is it? 6 and the transmission ratio l imw? 40 is chosen, where where nm: drive motor speed and nw: roller speed (10, 20). The invention further relates to a planing device for flattening films or sheets, and a process for producing sheet material, in particular films or sheets. fig. 1
