Abstract (en)
[origin: WO2016083170A1] A method for producing packaging paper, in particular sack kraft paper, is specified, in which method fibrous stock suspension is thickened in a stock preparation to a solids concentration in the range from approximately 30% to approximately 35% before high-consistency refining, the fibrous stock suspension is subjected to low-consistency refining at a solids concentration in the range from approximately 1% to approximately 3% after the high-consistency refining, the fibrous stock suspension is applied by means of a headbox with a stock consistency of < 0.5%, in particular with a stock consistency in the range from approximately 0.15% to approximately 0.25%, onto the Fourdrinier wire of a Fourdrinier former or a hybrid former for dewatering and forming of a fibrous web, the Fourdrinier wire is excited to perform shaking movements, in particular in the initial sheet forming zone, and the fibrous web which is formed is dewatered further in a pressing section and is dried in a drying section.
