Förfarande och anordning vid formning av en matta av partiklar

摘要

Methods for forming particle mat from lignocellulose-containing particles in the production of sheet material are disclosed including providing a flow of lignocellulose-containing particles from a supply source at an elevated height, depositing the flow of lignocellulose-containing particles from that height by means of gravity onto a forming belt at a lower height, and retarding the flow of lignocellulose-containing particles as it passes from the upper height to the lower height. Apparatus for carrying out the method is also disclosed.
