ABSTRACT This invention relates to a wear means, which is arranged within a rotary drum barker as a wear protection of the drum mantle and is connected with this by means of a bolt joint. In rotary drum barkers the regions where discharge openings for the bark are arranged are subjected to a heavy wear. Therefore the wear means of the invention are preferably arranged in these areas. What characterizes the wear means of the invention is that it comprises a wear body of wear-resistant rubber and a prestressing means which is connected to the wear body so that it absorbs forces. Moreover, the wear means has a sleeve-shaped central portion in connection with the prestressing means, the central portion extending into a hole in the drum mantle of a bolt included in the bolt joint and surrounding this.
