PROCESS FOR IDENTIFYING CONTROLLING ELEMENTS DURING THE CROSS-SECTION REGULATION OF A CONTINUOUSLY PRODUCED WEB OF MATERIAL
A plurality of controlling elements to be identified are adjusted by the same amounts which at the end of the web intervene only within the noise level. A series of cross-section measurements are then carried out, from which a previously determined mean value of the cross-section is subtracted and the results are superimposed until a number of measurement signals corresponding to one of the controlling elements to be identified clearly detach themselves by their amplitude and/or shape from the superimposed noise components of the cross-section.
