<p>The invention relates to a process for directing a papermaking pulp towards a regulated outlet (9). Accept from successively arranged cleaning stages (6, 14, 20) is lead towards the outlet (9), while the respective rejects are lead to the inlet of the succeeding cleaning stage (14, 20). Depending on the operational situation, the accept from the cleaning stages (6, 14, 20) is totally or partly lead towards the outlet (9) while excess accept is lead in the opposite direction to the inlet (5) of the preceding cleaning stage (6). The invention also relates to an arrangement for the feeding of a forming wire, wherein a collecting accept pipe (8) is provided for extending between the outlet (9) and a feeding (3) for fresh pulp, while reject pipes (11, 18) lead to the next cleaning stage (14, 20). The invention further relates to a cleaning arrangement, wherein the accept outlets from the respective cleaning stages (6, 14, 20) are consecutively connected to a common base pipe (8) whose one end (8a) is connected to the regulated outlet (9) and whose opposite end (8b) is connected to an inlet (5) to the first cleaning stage (6).</p> |
