ABSTRACT:
An apparatus for separating bark, such as birchbark, from timber during conveyance of the timber has a conveyor for advancing logs leaving a stripping drum. To achieve an effective separation of bark, rollers conveying the logs form a bark separating unit, where successive ones of the rollers are arranged at two levels, the rollers at the upper level being provided with spikes for scraping or detaching the bark, and the rollers on the lower level being substantially smooth-surfaced.
