摘要： Stock inlet of a paper machine that includes at least one stock suspension supply, a diffusor block having a plurality of tubular elements, dividing elements which extend across a width of the machine, and a stock inlet aperture having a top wall and a bottom wall. The dividing elements are located between the top wall and the bottom wall, so that a plurality of suspension conduits are formed, which extend across the width of the machine. Further, the stock inlet aperture is positioned one of adjacent one wire and between two wires. The suspension conduits include a first region and a second region disposed downstream of the first region, with respect to a stock flow direction. The first region is formed by flat boundary surfaces which extend across the width of the machine and converge in the stock flow direction, and each of the dividing elements has a sharper convergence of surfaces in the second region than in the first region. The plurality of tubular elements are associated with a turbulence generating element to produce secondary turbulence currents in partial suspension flows conveyed through the plurality of tubular elements. In this way, the secondary turbulence currents overlap a primary current of each partial suspension flow, and all of the dividing elements have a contour and an arrangement so that the second region for each suspension conduit is of equal length and has an identical cross sectional course.

The paper or cardboard machine includes at least one headbox that extends across a machine width. The at least one headbox is adapted to provide a machine-wide distribution of a material suspension onto one of a screen and between two screens. The machine also includes at least one material suspension supply coupled to the at least one headbox and adapted to supply a material suspension to the at least one headbox. The at least one material suspension supply has at least one concentration. At least one first control loop is provided that includes at least one actuator being adapted to adjust the at least one concentration of the at least one material suspension supply, at least one detector for determining a basis weight of a finished web, at least one supply being adapted to modify the at least one concentration of the at least one material suspension supply, and at least one device that adjusts the at least one actuator. In this manner, the at least one concentration of the at least one material suspension supply is adjusted. At least one second control loop is provided that is adapted to regulate the concentration of the material suspension supply. The method includes determining a basis weight at an end of the manufacturing process, calculating a deviation of the determined basis weight from a predetermined target value, adjusting a concentration of a material suspension supplied to a headbox via a first control loop such that the calculated deviation is corrected, one of directly and indirectly measuring a basis weight of a resulting web in a region upstream, with regard to a web travel direction, a drying section, and supplying a signal related to the measured basis weight to a second control loop.
