Abstract
Multilayer headbox in a paper machine or cardboard machine, which has two or more flow channels for pulp suspension on each, via which the pulp suspension is fed onto the wire, above which the paper or cardboard web is formed. The flow channels include a distribution bar 10, a distribution pipe system 11 or the like, a turbulence part and a lift part. In conjunction with the flow channels, lying on each other, of the multilayer headbox, an intermediate part is installed with channel divisions, in whose intermediate walls 15D, 15E; 15'D, 15'E, which separate the flow channels from each other, there are openings along a part or the entire length of the intermediate part in which opening a moving disk-like wall parts 40 are arranged, which function as pressure equalizers between the different flow channels of the headbox. <IMAGE>
