Beschreibung
Zusammenfassung:	Measuring devices measure at least one characteristic of the fibres of recycled fibre pulp and at least one characteristic of ink, and the measuring devices feed the measurement results to controllers of a pulping subprocess and a dispersing subprocess, the controllers performing multivariable-based predictive calculation and optimization of control functions. The controllers of the pulping sub-process and the dispersing subprocess generate control variables on the basis of the measurement results for mechanical and chemical processing of the recycled fibre pulp to be performed in the pulping subprocess and the dispersing subprocess.
