Abstract
Apparatus for removing bark from logs, particularly from logs of stringy-bark eucalyts and other rough-barked tree species, and for crushing logs, consists of a plurality of pairs of concave rollers which are mounted in spaced-apart relationship along the linear passage of the log through the apparatus. Each pair of concave rollers applies pressure to regions of the log to loosen the bark from the body of the log. Knives may be included on the concave surfaces of some or all of the rollers to cut the loosened bark.
