A rolling device for producing a dry film having

• a first calender roll and a second calender roll,
• wherein a dry powder
• mixture is introduced into a nip between the first calender roll and the second calender roll,
• wherein the first and the second calender rolls are configured or driven such that the first calender roll has a higher rotational peripheral speed than the second calender roll, and such that the first and the second calender rolls respectively have an opposite direction of rotation,
• wherein the rolling device is configured to maintain a ratio of the rotational peripheral speed of the first calender roll to the rotational peripheral speed of the second calender roll of 10:9 to 10:1.
