Abstract
A method and apparatus for combining a dilution flow with a stock flow passed out of an inlet header in a paper/board machine including dilution flow ducts through which the dilution flow is passed to selected locations across the width of the headbox of the paper/board machine in order to regulate the basis weight of the paper/board web. The dilution flow ducts are constructed so that they becomes narrower toward a final, downstream end. Branch ducts are placed in the area of the narrowing portion of each flow duct, and the dilution flow is passed out of the branch ducts into the system of pipes wherein the dilution flow is combined with the stock flow passed out of the inlet header.
