Rosendahl Nextrom GmbH, a global technology leader in the cable, wire, fiber optics and battery industries, has acquired the Estonian WINDAK Group, a specialist in automated coiling, packaging and logistics solutions. As a result of the transaction, WINDAK becomes part of the Rosendahl Nextrom Group, a member of the Austrian-based KNILL Group.

“WINDAK is an excellent strategic fit,” said Gerhard Jakopic, CEO of Rosendahl Nextrom. “By combining our strengths, we expand our technological scope and create additional value for customers worldwide. This step allows us to address customer requirements more comprehensively while continuing our global growth strategy.”

Following the acquisition, WINDAK will continue to operate as an independent business unit with a location-based management structure. Johann Jaekel and Ashley Brettell will be based in Tallinn, while Dan Shelander and Madis Tomson will be managing the US branch. This setup ensures continuity in leadership, close collaboration with customers and teams, and a smooth integration process.

“Our priority is a seamless integration with minimal disruption,” explained Siegfried Altmann, CEO of Rosendahl Nextrom. “Customers can rely on continuity, established contacts and the same high level of technical expertise.”
