Abstract
Apparatus for and method of restoring a damaged area of a coating on a drum body includes a treatment station with a coating-removal unit which initially mechanically frees the damaged area from remaining coating. After cleaning the freed damaged area, a patch is inserted and united with neighboring coating material through hot vulcanization or hot pressing for bonding to the drum body, with the patch having a material composition corresponding to the coating material. Finally after curing, the thus-restored area is surface finished to match the restored coating to the dimension and surface finish of the remaining coating of the drum body.
