Abstract: An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a “bull-nose” configuration with substantially vertical sides.
