Abstract

A headbox intended for pulp with a consistency of 6-15%. The headbox comprises a pressure chamber 1 in which one wall 2 is formed by flow openings 3 that discharge into a chamber 14 from which the pulp is supplied fluidized onto a forming surface 7 through an outlet opening 17 directed toward the forming surface. An opposite wall in chamber 14 forms a stop surface 15 for the pulp streams from openings 3, as well as an outlet gap 16 between the lower edge of the walls and the forming surface. <IMAGE>
