Abstract

A method for the processing of pulp to be used in the manufacture of paper or cardboard, in which method the pulp is led from a pulp source to pulp processing and further into the circulation and the headbox of a paper or cardboard machine. The pulp processing takes place in a pulp processing pipework in such a way that the pulp flow proceeds continuously at a rate determined by the volume flow.
