In a process for producing wood-fibre boards, the raw material is first defibrated, then mixed with aqueous binder liquor in a blast pipe. The binder-coated fibrous material thus obtained is dried to the required residual-moisture content and then spread out into strips which are converted by the action of pressure and heat into boards. The mixing procedure is carried out using a liquor containing 20-35 % by wt. of solid resin, and the amount of binder used, relative to the total dry weight of the fibre material, is less than 10 % by wt. |
