A new chapter begins
Josef Altmayr has assumed leadership of the business, succeeding Johann Jäkel after a carefully planned transition.
Having joined Rosendahl Nextrom in 1990 as a process engineer for cable and wire, Altmayr brings decades of experience and a deep understanding of the business. Over the course of his career, he has held a variety of leadership positions, including Head of R&D, Technical Director, and Group COO. Most recently, he served as Head of Supply Chain Management for the entire Rosendahl Nextrom Group.
Along the way, Altmayr helped shape important technological and organizational milestones, including advancements in foaming technology and the development of the ROEX extruder generation. His broad experience across engineering, operations, and management gives him a unique perspective on the challenges and opportunities facing the cable and wire industry today.
Returning to Cable & Wire feels like coming back to my roots. I look forward to reconnecting with our customers and working closely with our dynamic team to further strengthen our position as a technology leader and build on the strong foundation established by Johann Jäkel.
For Altmayr, innovation begins with understanding customer needs and translating them into practical solutions.
“Our ambition is not only to follow technological developments, but to anticipate them — and to help our customers turn them into competitive advantages.”
Looking ahead, he sees digitalization, artificial intelligence, and automation as important drivers of future growth.
“The pace of technological change is accelerating. We want to make even greater use of technologies such as AI and robotics – both within our operations and in our equipment – to further increase quality, performance, and value for our customers.”
Building on a strong foundation
Altmayr succeeds Johann Jäkel, who has led the Cable & Wire Business Unit since 2019. During his tenure, the business strengthened its position in key growth markets such as e-mobility, energy, and data center solutions, expanded its global footprint through the opening of the Mexican office, and completed the acquisition of the Estonian Windak Group.
“We set the right strategic direction and built a strong foundation for long-term success,” says Jäkel. “Josef is the ideal successor because he has personally helped develop many of our core technologies and brings unique experience across technology, operations, and the commercial side of the business.”
As part of the planned transition, Jäkel will dedicate his final year with Rosendahl Nextrom to supporting the integration of Windak into the Rosendahl Nextrom Group.
