Abstract (en)
[origin: WO2013017344A1] The invention relates to a sheet forming system (1) for a machine (100) for producing a two-layer or multi-layer web (2) from at least one fibre suspension (3), comprising a two-layer or multi-layer headbox (4) with a headbox nozzle (5), which has at least two nozzle chambers (24.1, 24.2), separated from one another by at least one separating element (23), each of which guides a fibre suspension (3) as a fibre suspension flow (3.1, 3.2), each of which has downstream an exit slit (25.1, 25.2) extending over the width (B) of the headbox (4), wherein the two outer nozzle chambers (24.1, 24.2) each have on the outer side an outer wall (26.1, 26.2), and wherein a plate (27; 30) is arranged on the discharge side of at least one outer wall (26.1; 26.2), and a Fourdrinier wire at the bottom outer wall (26.1) facing the Fourdrinier wire (7, 7.1) has an plate angle (27. W) of > 15° and the plate (27) having an orifice projection (27. V) of > 1 mm.
