    摘要： The invention relates to a method for producing highly filled papers, in particular decorative papers for application on a substrate material, from an aqueous suspension, wherein the suspension is applied onto a revolving drainage screen by means of a headbox (1), comprising a turbulence generator (2) having a plurality of turbulence channels (7.1n, 7.2n, 7.3n, 7,4n) arranged side by side forming a row. Immediately adjacent to and downstream of the turbulence generator (2), a nozzle (3) is arranged, and the suspension is guided through the turbulence channels (7.1n, 7.2n, 7.3n, 7,4n) and through the nozzle (3) to form a suspension jet. The method according to the invention is characterized in that the papers are produced from an aqueous suspension having a total stock consistency of more than 1.5 %, a fiber stock consistency of less than 1.2 %, an ash mass fraction of greater than 30 %, and that at least three rows (7.1, 7.2, 7.3, 7.4) are arranged one above the other, and that the suspension is guided through the turbulence channels (7.1n, 7.2n, 7.3n, 7,4n) having a maximum hydraulic diameter (12) of less than 25 mm, in particular less than 20 mm, and subsequently, is guided through a nozzle (3) having a length (6) of more than 500 mm, in particular more than 700 mm, and that lamellae (4) are placed in the nozzle (3) between the adjacent rows of the turbulence generator (2), which, starting at the turbulence generator (2), extend over at least a portion of the length (6) of the nozzle. The invention further relates to a headbox for carrying out the method.

    摘要： The invention relates to a valve (1) for regulating a fluid flow (2), in particular a fibrous material suspension flow (2.1) preferably guided in a machine for producing a fibrous material web, in particular a paper, cardboard or packaging paper web, said valve comprising a hollow body (3) having a cavity (4) which at least in some sections is substantially rotationally symmetrical and has a longitudinal axis (L.4). Said cavity includes at least one inlet opening (5) having a longitudinal axis (L.5) and an inlet conduit (5.1), and further includes a variable and substantially rotationally symmetrical passage surface (6) and an outlet opening (7) having an outlet conduit (7.1). The valve further comprises a preferably rotationally symmetrical valve rod (8) which can be displaced coaxially in the cavity (4) of the hollow body (3) preferably by means of at least one actuating means (10), can vary the passage surface (6) as a result of a displacement (V) and in particular comprises a valve disc (9). The valve (1) according to the invention is characterised in that the inlet opening (5) in the hollow body (3) is disposed in such a way that the longitudinal axis (L.5) thereof intersects the longitudinal axis (L.4) of the cavity (4) of the hollow body (3) at an intersection point(P), and that the cavity (4) of the hollow body (3) is designed in such a way that the fluid flow (2), in particular a fibrous material suspension flow (2.1), having a main flow direction (H) flows through said cavity without stagnation points or approximately without stagnation points and without rotations or approximately without rotations relative to the longitudinal axis (L.4) of the cavity (4).
