Abstract (en)
[origin: WO2021073997A1] The invention relates to a monitoring method for monitoring at least one part of a production process of a film extrusion system (10) using a production model (PM), having the following steps: − detecting at least one model parameter (MP) in the form of an output parameter (AP) of the production model (PM) in order to detect a film product situation, − determining a differential value (DW) between the at least one detected output parameter (AP) and a correlating set-point value (OW), − forming a parameter relationship between the determined differential value (DW) and at least one model parameter (MP) in the form of an input parameter (EP) of the production model (PM), and − generating at least one control value (TW) as a specification for the at least one input parameter (EP) of the formed parameter relationship.
