Abstract: A barking machine comprises a container for accommodating logs longitudinally therein, this container having a longitudinal side wall with a lower end, and a bottom wall including a first longitudinal opening adjacent to the lower end of the first side wall, a second intermediate longitudinal opening, and a third longitudinal opening. First, second and third longitudinal drum members are rotatively mounted in the first, second and third longitudinal openings, respectively, to expose a top portion thereof inside the container. A plurality of outer barking teeth are distributed on the rotary drum members to contact the logs and thereby bark these logs. Finally, a drive system rotates the drum members in the same direction for moving the barking teeth of the top portion thereof toward the longitudinal side wall.
