Abstract: The invention relates to a method for controlling the formation of a fiber web of a fiber or paper producing process. The method consists of a plurality of successive individual method steps in which controllable chemical and/or physical sequences or process steps are carried out dependent on measured values, and the materials required for the formation of the fiber web are treated, combined, and/or dewatered in said sequences or process steps, wherein at least some of the measured values are detected inline and directly or indirectly used in order to control the formation. The proposed method is characterized in that at least the manipulated variables, which influence the formation in a relevant manner, of the individual sequences or processes are formed dependent on definable secondary conditions during the entire process.

Abstract: The invention relates to a method for conducting water in a machine for producing and/or finishing a paper, cardboard, tissue or other fibrous web having a plurality of machine elements and at least one water circuit (I, II). Here, the outlay for the water conditioning is to be reduced by virtue of the fact that the wastewater (1) with low contamination of at least one machine element is collected separately and is reused in a machine element without being mixed with a wastewater from the water circuit (I, II).
