Roller leveller
Roller leveller
The GEORG high-performance Roller leveller includes integrated, fully and semi-automatic changing systems, whose sets of levelling rollers have a six-high or four-high design, depending on requirements. The change cassettes are easy to install and remove and considerably extend the levelling range as a result of the different diameters of the levelling rollers.
The settings of the roller leveller can be called up at any time on the optimized visual display system at the control panel. Operating instructions and error messages inform the user about the system’s status in real time.
The compact main drive unit ensures that the roller leveller has a smaller space requirement. The hardened gear wheels are mounted on anti-friction bearings, while their flanks and bearing seats are ground. The required high torques for levelling high-tensile strips with the smallest possible diameter levelling rollers are transferred via ball joint shafts with reinforced fork heads and balls. The joints are lubricated internally for better cooling and lubrication of sliding surfaces.

Roller leveller handling systems
The demands placed on surface finishes in the steel and aluminium strip processing are becoming more and more stringent. This means, e.g., for the manufacturers of outer skin panels for the automotive industry a significant increase in additional expenses for cleaning the levelling roller cassettes. We have broadened our range in order to provide producers support in this regard.
Gentle surface treatment calls for clean levelling rollers. Our automatic levelling roller cleaning unit ensures a long-lasting cleaning of the levelling rollers without the machine being stopped.
The GEORG cassette quick-change systems have been developed for a crane-independent changing of the levelling roller cassettes. The change systems offer the following advantages.
- Extension of levelling range: With two levelling roller cassettes, it is possible to process the strip thickness range of 1:10 (e.g. 0.4 - 4.0 mm) with one levelling machine.
- Variety of materials: On a cut-to-length system, different materials, such as stainless steel and aluminium strips or even hot- and cold-rolled strips, can be processed with 2 or 3 levelling roller cassettes.
- Saving time: The cassette change time is reduced by 10 to 25 min, depending of the degree of automation.
Our cassette inspection table simplifies the acceptance of the upper part of the cassette and enables a quick maintenance of levelling rollers.
