Abstract (en)
[origin: WO2010066514A2] The invention relates to an arrangement for obtaining a fiber suspension for producing a web of paper, cardboard, tissue, or other fibers from at least one high-consistency flow (1) containing fibrous material and filling material in the approach flow system of a fiber web manufacturing machine, at least one high-consistency flow (1) being directed through at least one screening device (3). In order to reduce the screening effort, the accept (4) from the screening device (3) is directed to the headbox (12) of the machine, and the reject (5) from the screening device (3) is redirected upstream into a high-consistency flow (1).
