| 摘要 |
The invention concerns an equipment for combining a dilution flow (L1) with the stock flow (L2) passed out of the inlet header (J1) in a paper/board machine. The equipment comprises dilution flow ducts (D1, D2...), through which the dilution flow (L1) is passed to the desired location across the width of the headbox of the paper/board machine so as to regulate the basis weight of the paper/board web to the desired level. The dilution flow duct (D1, D2...) is constructed in such a way in its final end (D1a, D2a...) that it becomes narrower towards its end. Branch ducts (E1.1, E1.2...; E2.1, E2.2...) are placed in the area of said narrowing, out of which branch ducts the dilution flow is passed into the system of pipes (11, G), in which the dilution flow is combined with the stock flow (L2) passed out of the inlet header (J1).
