<p>A multivariabie controller (634) receives from a recycled fibre line at least two measuring results, of which at least one relates to accept measurement and at least one to reject measurement. The multivariable controller (634) controls on the basis of at least one accept-related measuring result and at least one reject- related measuring result the mechanical processing of the flotation process and the supply of at least one chemical affecting flotation into the recycled fibre process</p> |
