Abstract

The invention relates to a method for producing a dry film (3), wherein a dry powder mixture is processed into the dry film (3) by a rolling device comprising a first roller (2a) and a second roller (2b). The first roller (2a) has a higher circumferential rotational speed than the second roller (2b), and the dry film (3) is placed on the first roller (2a).
