The invention relates to a method for renovating an inner drum shell surface (4) of a barking drum (1), said barking drum comprising a cylindrical drum, rotatable around its substantially horizontally disposed centre axis (2), through which tree trunks (3) to be barked are delivered for barking the tree trunk and separating the bark from wood material and which barking drum (1) includes a number of log lifters (5) extending inwards from the inner drum shell surface (4) and a number of elongated bark slots (6) extending through the inner drum shell surface (4) of the barking drum. The inner drum shell surface (4) of the barking drum (1) is coated intermittently with an annular section at a time. A new inner surface for the barking drum (1) is compiled from two or more annular sections, and each annular section is produced by welding a number of form-moulded plates (8, 9, 10, 11) of substantially equal mutual size and shape securely to the inner drum shell surface (4) of the barking drum (1) and to each other. |
