Abstract

The invention relates to a process for individually regulating the distribution of filling material and fine material in a papermaking and board-making machine. The pulp which is fed to a multi-layered flow box is laminated with retention agent such that retention agent is dispensed to the various layers on the basis of an electromechanical property of the pulp fed to the multi- layered flow box, the distribution of the filling material and fine material in the web in the Z-direction of the web being able to be regulated according to requirement. <IMAGE>
