Intelligent straightening for roll formers
The intelligent straightening device developed by Dreistern assists the operator in quality control during the roll forming process. By continuously monitoring profile quality, it is designed to not only reduce the operator’ s workload but also enhance process transparency. The device recently won a“ best Award”, in the‘ presses and forming technologies’ category, at the Blechexpo / Schweisstec trade show in Stuttgart( October 2025).
Dr. Cornelia Tepper( Dreistern GmbH & Co. KG) and Johannes Hofmann, M. Sc.( PtU Darmstadt, Institute for Production Engineering and Forming Machines), outlined the benefits of the device for the roll-forming process.
“ In industry, the pressure to design production processes that are resourceefficient, effective and sustainable is continuously increasing. This is driven by rising material and energy costs, stricter legal requirements and growing public expectations for sustainable production. Additionally, advancements in material science are leading to new materials being introduced into manufacturing, thereby increasing the complexity of existing forming processes. The automotive industry is one of the key examples in this field, as it is increasingly employing ultra-high-strength materials in sheet metal applications. This presents challenges for existing process chains in forming technology, for which the roll-forming process provides the ideal solution,” they told ISMR.
“ The range of applications for the rollforming process is continuously expanding, driven by advances in forming, punching and welding technologies. This enables the processing of increasingly demanding materials in rollforming lines. However, it also leads to greater overall process complexity. Smart components in the roll forming line, such as the intelligent straightening device and its integrated evaluation algorithms, assist the operator in process control and enhance overall process efficiency,” they continued.
