Abstract

A process for the manufacture of lignocellulosic material fibreboard wherein the fibre impregnation step takes place when the latter is wet, at the delivery from the grinder operating at high pressure and passage to the dryer. This impregnation is effected with a binder mixture having a resin solids content lying between 40% and 45% and a viscosity of less than 15 cps, prepared from a tack free urea-formaldehyde resin having a solids content of 60% to 70%, a viscosity at 25.degree.C lying between 150 and 300 cps and a free formaldehyde value of less than 1%.
