Abstract: 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.

Abstract: A toothed crushing disk for a grain processor includes teeth having a trailing tooth flank, which is a so-called tooth back, and a leading tooth flank, which is a so-called tooth face, on the surface of the teeth. The teeth have a wear protection zone in the region of the tooth back which is continuous or is divided into partial zones and has a wear resistance which is greater than that of the material of a base member of the toothed crushing disk. The base member has a tooth structure which determines the shape of the teeth and the wear protection zone is produced by using a high-energy beam method with the geometry of the tooth structure being substantially maintained. A method for producing a toothed crushing disk for a grain processor having teeth on the surface thereof is also provided.

Abstract: A cutter bar has a cutter body with a substantially rectangular cross section formed by an upper face, two side faces and a lower face. The upper face together with at least one side face defines a cutting edge, which is formed by one or more hard metal profile strips fastened in a groove in the cutter body. The wall of the groove which adjoins the upper face of the cutter body encloses with the upper face of the cutter body an angle less than 90°, preferably 89 to 15°, particularly preferably 80 to 40°. The wall of the groove which adjoins the lateral face of the cutter body encloses with the lateral face of the cutter body an angle less than 90°, preferably 89 to 15°, particularly preferably 80 to 40°. The hard metal profile strip or hard metal profile strips is or are positively inserted in the groove.
