Abstract (en)
[origin: WO03080922A1] The invention relates to a method for adjusting the fibrous properties of chemical pulp, mechanical pulp or chemi-mechanical pulp, for adjusting the smoothness of the properties and for decreasing any variation in quality. According to the method, in the manufacture of pulp, a wood material is used, which is selected according to the number of the tree's annual rings. The wood material is classified according to the number of annual rings into categories that represent a certain fibre dimension property, such as the fibre length or the fibre coarseness. The wood material is classified by log or group of logs at any stage in connection with the felling of the wood or in the plant or at some stage of the chain between the stub and pulping and grinding or a refiner.
