“Our slogan, ‘Roofs and walls for generations,’ is not only a promise of quality to our customers, but also to our team! We are now in our fifth generation and want to offer good, secure, and attractive jobs – both now and in the future,” says Nadja Kratky, managing director, master roofer, and business economist in the skilled trades.

The company is managed by senior partner Thomas Kratky, Nadja Kratky, and Stefan Knopp-Kratky. With daughter Nadja and her husband Stefan, the company is now transitioning into the fifth generation.

demonstrates with nuEVOLUTION how simple and efficient the planning and production of profiles can be.
State-of-the-art technology
When you enter Kratky’s production hall, the first thing you notice is the row of machines from the Cidan Machinery Group, which are designed for highly efficient production. An 8-fold decoiling solution feeds the desired material directly into the nuSLIT, a modular straightening and cut-to-length line from Forstner that ensures precise cutting. The loading table of the Thalmann TD double folder allows easy positioning of the blanks for automatic lateral sheet feeding. After the sheets are automatically flipped, the finished profiles are transported – also automatically – to the removal unit, where they can be conveniently removed.
Software and machinery in harmony
At Kratky, nuEVOLUTION enables user-friendly and versatile planning for efficient profile production. The innovative software not only connects the linked machines, but also offers numerous useful functions: an editor for drawing profiles including a 3D view, automatic creation of order-related documents, and a comprehensive profile database whose parameters can be adjusted in no time at all.
“Yes, for us as a customer, it is a great advantage to get everything from a single source, as with Cidan Machinery Group, and to have a dedicated contact person who takes care of everything,” summarizes Stefan Knopp-Kratky, master roofer and one of the three managing directors of Kratky GmbH & Co. KG. “The investment in automation solutions has paid off in many ways. Not least, it has enabled us to ‘save’ the equivalent of 1.5 employees in production, who we can now deploy more efficiently or in other areas.”
