METHOD AND SYSTEM FOR PRODUCING A FIBER WEB
The invention relates to a method and to a system for preparing a finished fiber suspension for the production of a web of paper, cardboard, tissue or any other fiber by mixing at least one high consistency flow (1) constituted of freshly prepared fiber and filler material with at least one rejects flow (3) constituted of remnants and fragments of the fiber web and at least one low consistency flow (2) constituted of fresh water, white water or the like, the flows (1, 2, 3) being guided towards a headbox (7) of a machine for producing the web of fiber. In order to reduce the costs and/or effort required, the rejects flow (3) is processed separately before it is mixed with the high consistency flow (1) and is not subjected to a cleaning step in the approach flow system (6) of the machine.
