Abstract
A drum for stripping branches, bark and like so-called waste from trees or like woody plants, or for at least pre-treating the trees or like woody plants in a manner to soften or crush the branches and bark thereon, comprises a plurality of mutually co-axial drum sections (1-6). For the purpose of preventing a tree from being lifted in the drum under the action of obliquely positioned stripping bars, the drum sections are rotated alternately in clockwise and anti clockwise directions, which also prevents the tree from being rotated about its longitudinal axis. The stripping bars, which co-act with openings (22, 23, 24) through which removed waste material is released from the drum, are obliquely positioned relative to the axis of rotation (27) of the drum. The stripping bar of each drum section is obliquely positioned relative to the stripping bar of an adjacent drum section.
