Method for coating wood chips with resinous liquid

Claim 3

The method of claim 1 including continuously feeding particles to be coated into one portion of said enclosure and continuously discharging coated particles from another portion of said enclosure.

Claim 4

The method of claim 1 including agitating said quantity of particles to move different portions of said quantity into wiping contact with the coated moving inner wall surface as said wall moves beneath said quantity of particles.

Claim 5

The method of claim 1 including repeatedly agitating said quantity of particles at different positions along said moving wall as the coated inner surface of said moving wall moves beneath said quantity of particles so that individual particles of said quantity are repeatedly moved into wiping contact with the coated inner wall surface.

Claim 6

The method of claim 4 including agitating the quantity of particles using a rotary stirring motion in a direction and at a speed such that individual particles of said quantity are wiped across the coated moving inner surface of said moving wall in the same direction of movement as said wall.

Claim 7

The method of claim 1 wherein said moving wall is cylindrical and said movement is rotational and unidirectional about the axis of said cylindrical wall.

Claim 8

The method of claim 1 wherein said moving wall is curved to define a concavely curved said inner wall surface and wherein said curved wall is continuouslly rotated in the same direction of rotation during the coating process so that said quantity of particles are contained generally along a lower inner surface portion of the rotating wall and so that the particles tend to be carried by the rotating wall upwardly along the coated inner wall surface in the direction of rotation.

Claim 9

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.

Claim 10

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.
