ABSTRACT:
The headbox contains a nozzle channel merging at a distributor device for the fiber stock suspension. The nozzle channel contains two lip members bounding a slice opening for forming a substantially flat stock jet. At least one of these lip members is subdivided into at least two lip portions which extend over longitudinal sections of the nozzle channel which are located behind one another in the flow direction of the fiber stock suspension and which are adjustably connected with one another and can be fixed in their adjusted position. At least one of these lip portions is adjustable relative to the distributor device and the neighboring lip portion of the same lip member essentially transversely to the stock flow direction towards and away from the oppositely located lip member, in order to change the pattern or course of the cross-sectional area of the nozzle channel. This enables accommodation of the geometry of the nozzle channel to different products and production requirements.
