A conveying and conditioning roller for a harvesting machine is provided on the surface thereof with teeth in the form of toothed strips which extend over the longitudinal extent of the roller and in each case have a leading tooth flank and a trailing tooth flank as well as a tooth edge. The roller is provided with wear protection zones continuously or in partial regions, the wear resistance thereof being greater than that of the material of the base body of the roller. The base body has a tooth structure determining the shape of the teeth and tooth wear protection zones are formed on the trailing tooth flanks by a high energy radiation process, substantially maintaining the geometry of the tooth structure, roller wear protection zones being formed together thereby on the rollers, as well as a method for producing such a roller wear protection zone.
