Zusammenfassung:The head box (1) has a nozzle (2) with two areas (8.1, 8.2), which are separated from each other by a separating wall (6), guide pulp suspensions (5.1, 5.2) as pulp suspension streams (7.1, 7.2) and extend over a breadth (B) of a multi-layered fiber web producing machine. Each nozzle area has an external wall (10.1, 10.2), an upstream supply device and a downstream outlet gap (9.1, 9.2) that extends over the breadth of the machine. The wall has a projection in the range of 0.2 to 1.5, and each outlet gap of the respective nozzle area has increased individual gap width (s9.1, s9.2).
