Abstract: A rotary log singulator for singulating logs received from an intake station to a downstream discharge station. The apparatus includes at least two longitudinally displaced rotating drums and at least one lifting and separating bar located adjacent to and upstream of the drums. The rotating drums have two perimeter portions defined by two chord stretches joined at an outwardly facing obtuse angle. Logs received by the drums are supported and rotationally transferred within the perimeter portions defined by the chord stretches. The lifting and separating bars are driven by a shaft connected to or synchronized with the shaft which drives the rotating drums and are displaced vertically up and down as the rotating drums rotate.
