Abstract: The invention relates to an installation for producing glued plant particles, in particular from annual plants (e.g. straw), in order to produce boards, e.g. fibreboards or chipboards, having at least one comminuting apparatus (2) for comminuting plant-based starting material to form scatterable plant particles, and having a gluing apparatus (15) for gluing the plant particles. This installation is characterized in that at least one first screening apparatus (3) for separating silicate particles from the plant particles is arranged between the comminuting apparatus (2) and the gluing apparatus (15).

Abstract: A laminar board having a base of bonded wood particles carrying a decorat facing is produced by sequentially moving a carrier web through a loading zone and a press zone. The carrier web consists essentially of paper impregnated with a synthetic resin composition and having a permeability to water vapor of at least 1000 g/m.sup.2 /day. A layer of loose wood particles intimately mixed with a bonding agent is superimposed on the carrier web in the loading zone, and the resulting layered material is subjected in the press zone to a temperature and pressure sufficient to bond the loose particles to each other by the bonding agent in a dense structure and simultaneously to bond the particles to the carrier web by the bonding agent and/or the synthetic resin composition.
