Abstract
An arrangement for attaching running rings to a rotary drum includes straps which hold the bore surface of the rings on a supporting surface of the rotary drum. The straps are circumferentially spaced apart on at least one of the two sides of the respective ring, and each of the straps has an axial projection with a support surface facing an engagement surface of the ring, the support surface facing radially inward. In order to prevent contact wear between the bore surface of each running ring and the respective supporting surface, each engagement surface and/or support surface is inclined toward the axis of the drum, in the direction extending axially outward of the respective running ring. The support surface of each strap is axially adjustable with respect to the engagement surface of the respective running ring, so that the bore surface of the rings can be pushed locally against the supporting surface of the rotary drum by the straps.
