Abstract
A method and apparatus for hydraulically debarking logs is disclosed, in which water at a substantially constant, ultra high pressure of, say, at least 25,000 KPa, is caused to impinge upon, generally radially with respect to, the surface of a log to be debarked. The apparatus of a preferred embodiment has ultra high pressure nozzles mounted upon resilient members circumferentially surrounding the log to be debarked, the members being biassed radially inwardly of the leg to bear upon the undulating surface thereof, and to maintain the nozzles at a predetermined distance therefrom, thereby maintaining the impinging water at a constant ultra high pressure.
Claims2
