Gerhard Groz and Michael Helbig brought the family business into the 21st century with numerous innovations.

Egon Franke, who had no children of his own, took steps at an early stage to continue the company beyond his lifetime. In 1974, he brought Gerhard Groz into the company, a man with an entrepreneurial mindset and approach. In Michael Helbig, Gerhard Groz has not only gained an innovative engineer as a colleague, but also a hands-on doer. Together, the two initiated extensive, sometimes far-reaching innovations in all areas of the company.
