Abstract

A headbox, for example, in a pulp or board machine, is suitable for high basis weights which are over 400 g/m<SUP>2 </SUP>and for high fiber suspension consistencies which are in a range of 2-5%. The headbox has a turbulence part ( 1 ), into which a fiber suspension flows from a tube bank ( 2 ), and a slice part ( 3 ) which is situated after the turbulence part and from which the fiber suspension flows to a forming section of a fibrous web. The turbulence part ( 1 ) of the headbox has at least two passages ( 5, 6 ), which converge in the flow direction of the fiber suspension towards the slice part ( 3 ). In that connection, the fiber suspension flow is first fluidized in a tortuous turbulence passage part ( 11 ) and, after that, it decelerates in another widening deceleration passage ( 12 ).
