An apparatus is disclosed for blending wood strands with a liquid resin. A process is also disclosed for continuously blending wood strands with a liquid resin. The apparatus overcomes some of the problems that exist with present day blenders because it avoids clogging spray nozzles and allows complete coating of the strands with a minimum amount of resin. The apparatus forms a substantially constant flow of wood strands into a first falling curtain of separated wood strands, the first curtain having a predetermined substantially constant width, a first liquid spray including at least one spray nozzle located on each side of the first falling curtain of separated wood strands away from the first falling curtain, adapted to spray liquid resin droplets for the width of the first curtain, but not substantially beyond; collector for collecting the first sprayed wood strands and forming them into a second falling curtain of separated wood strands, the second curtain having a predetermined width, and a second liquid spray including at least one spray nozzle located on each side of the second falling curtain of separated wood strands away from the second falling curtain, adapted to spray liquid resin droplets for the width of the second curtain but not substantially beyond.

A process for continuously blending wood strands with a liquid resin, comprising the steps of: advancing a substantially constant flow of wood strands to form a first falling curtain of separated wood strands, the first curtain having a predetermined substantially constant width; spraying liquid resin droplets on each side of the first curtain, the spraying extending from both sides of the width of the first curtain, but not substantially beyond; collecting the first sprayed wood strands and advancing the first sprayed wood strands to form a second falling curtain of separated wood strands, the second curtain having a predetermined substantially constant width; and spraying liquid resin droplets on each side of the second curtain, the spraying extending from both sides of the width of the second curtain, but not substantially beyond.
