Abstract (en)
[origin: WO2020094644A1] The invention relates to a method for monitoring an edge section (RA) of a film web (FB) in a flat film machine (100), having the following steps: - sensing a thickness profile (DP) in at least one edge section (RA) of the film web (FB) in a transverse direction (QR) transverse to the production direction (PR) of the film web (FB), - comparing at least a portion of the thickness profile (DP) of the edge section (RA) sensed with a reference profile (VP), - determining a profile deviation (PA) as a result of the comparison, - performing a control intervention on the flat film machine (100) on the basis of the profile deviation (PA) determined.
