the filtration process begins. The major functions of the headbox are: to assure uniform distribution of flow across the paper machine; to provide velocity control of the jet leaving the headbox by the pressure in the headbox; and break up of pulp flocs by turbulence within the headbox. These functions are achieved by causing the stock to flow

For Kraftliner production, the kraft pulping process is used. This is a highly alkaline cooking process with caustic soda and sodium sulphide as active cooking chemicals. The cooking takes place in a digester at high pressure and a temperature of 150 170 oC. The pulp yield is normally around 55% ( 1000 kg of dry wood gives 550 kg of pulp).
