The acquisition represents a strategic expansion of Rosendahl Nextrom’s technology portfolio, adding downstream solutions that complement the group’s existing expertise in production and processing technologies. Customers will benefit from a broader, more integrated offering along the cable and wire value chain. Headquartered in Tallinn, Estonia, Windak designs and manufactures advanced equipment for coiling, packaging and material handling for the cable and wire industry.
“Windak is an excellent strategic fit,” says 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,” explains Siegfried Altmann, CEO of Rosendahl Nextrom. “Customers can rely on continuity, established contacts and the same high level of technical expertise.”
Founded in 1994 in Stockholm, Windak has evolved over three decades from a machine builder into a global leader in automated packaging and coiling solutions for the cable industry. Today, the company operates internationally and supports customers in increasing productivity, efficiency and sustainability.
Windak former CEO Staffan Edström comments on the transaction: “Rosendahl Nextrom provides the right industrial environment to ensure stability and to continue Windak’s successful growth path.”
