In the wood-working industry, bark is often undesired. There are several methods of mechanical debarking for further processing in the pellet, paper and pulp industry, but also for preventive treatment against pest and fungal infestation.

The roller debarker by Rudnick & Enners effectively removes the bark from cut wood and thinning material of various diameters, at a low rotational speed of the rotating cylinders and via reciprocal friction.
