Method for coating wood chips with resinous liquid

In a process of manufacturing a composite board product, the method of coating a quantity of wood particles with a resinous liquid binder preparatory to forming the coated particles into said composite board product comprising the steps:

• feeding wood particles continuously into an entrance end of a continuously, unidirectionally rotating, generally horizontally disposed drum so that said particles tend to accumulate along a lower inner wall portion of said drum,
• coating an inner wall portion of said rotating drum with a resinous binder at a position upstream of the accumulation of said particles so that rotation of the drum moves said coated inner wall portion toward said accumulation,
• continuing the rotation of said drum to move the coated inner wall portion beneath the accumulation of particles,
• simultaneously with the movement of said coated inner wall portion beneath the accumulation of particles, stirring the accumulation of particles to move the particles into wiping contact with the coated inner wall portion to transfer the resinous binder from said inner wall portion to said particles,
• and while continuing the wiping contact of the particles with the rotating coated inner wall portion of said drum as aforesaid, moving the particles from said entrance end of said drum to an opposite exit end thereof and discharging the coated particles from said exit end.
