Abstract: A log bark peeling apparatus comprising nozzles (55) through which high-pressure water is sprayed onto the log. Conveyor means are provided to advance the log in a path (16) through the bark peeling apparatus. The apparatus comprises a first unit (21) which is mounted for rotation about said path, said unit comprising an annular water housing (28) arranged, upon its rotation, to contain a co-rotating ring of water, and a second rotatably mounted unit (22) which supports at least one pitot tube (60). The pitot tube is intended to move with a mouth (61) formed therein foremost in a direction opposite to the rotation of the ring of water and via a channel (48) it communicates with one of the nozzles (55). Upon rotation of the two units in opposite directions water from the ring of water is forced into the mouth (61) of the pitot tube (60) through said channel (48) to be ejected through said nozzle (55) in the form of a jet. The jet is directed against the log (6) which is located in the path and thus in the centre of rotation upon advancement of said log along the path.
