• unwinding the web out into a cuffing device while at the same time a straightening element is pressed against the web on the side of the recording layer wherein the straightening element is a roller of a diameter of between 8 mm and 16 mm as a decurling bar;
• and conveying the web of the long roll body when straightening the curl such that it is contacted with the straightening element with a wrap angle of less than 60 degrees, and
• wherein the wrap angle is the angle formed by the crossing of the straight lines linking the center of the decurling bar to the edges of the area of contact of the long roll body web wrapping around the decurling bar.
