Abstract

In a paper or cardboard making machine, the transverse surface-weight profile of the web is regulated by feeding an additional flow to various sites in front of the lip opening 2 in the transverse direction to the main pulp flow entering the inlet box. The additional liquid flow is fed to the main pulp flow at one or more flow pathways, such as a distributing pipe 7, which are separated from each other in the transverse direction in such a way that it is mixed in with the main pulp flow through the action of the flow in said flow pathway no later than at the junction site of the flow pathways, such as in the rear wall of the equalising chamber 8. The feed sites are situated in the zone of action of one or more flow pathways which are separated from each other in the transverse direction of the inlet box, which flow pathways are joined into a chamber. The feed sites 11 are in communication with an element for controlled feeding of pulp, whose thickness differs from the flow of main pulp or water for the flow of main pulp. The feeding site is a channel 11 which opens up near the beginning of the flow pathway 7. <IMAGE>
