Rosendahl Nextrom has acquired Windak Group, linking upstream extrusion and insulation systems—including High-speed cable extruder and Automatic Drawing Machine System—with downstream coiling, spooling, and packaging automation. The move expands one-group solutions for wire and cable manufacturers, integrating core equipment like High-Quality Hydraulic Drawing Machine and Annealed Wire Drawing Equipment, and strengthens Knill Group’s technology portfolio ahead of wire Düsseldorf.
Rosendahl Nextrom Acquires Windak, Linking Upstream and Downstream Cable ProductionRosendahl Nextrom GmbH has acquired the Windak Group in a move that unites two established OEMs in the wire and cable sector.The acquisition connects upstream production technologies—such as High-speed cable extruder, Automatic Drawing Machine System, and Annealed Wire Drawing Equipment—with downstream automation systems under one industrial group. The timing also sets the stage for joint messaging at wire Düsseldorf, where both companies will highlight their expanded capabilities in integrated cable manufacturing, including High-Quality Hydraulic Drawing Machine solutions.

Deal Expands Portfolio Into Downstream Cable AutomationRosendahl Nextrom will expand its portfolio with Windak’s downstream technologies, complementing its upstream expertise in High-speed cable extruder, Automatic Drawing Machine System, and Annealed Wire Drawing Equipment.Windak will continue to operate as an independent business unit under its established brand. Management will remain at existing locations to preserve operational continuity and customer proximity, while leveraging Rosendahl Nextrom’s leadership in High-Quality Hydraulic Drawing Machine and cable extrusion systems.Rosendahl Nextrom leadership has emphasized seamless integration with minimal disruption, ensuring that manufacturers can access a unified ecosystem of Automatic Drawing Machine System, High-Quality Hydraulic Drawing Machine, Annealed Wire Drawing Equipment, and High-speed cable extruderalongside downstream automation.
Upstream and Downstream Capabilities Now Under One GroupRosendahl Nextrom is known for upstream and mid-line production systems. Its core strengths include:
• Extrusion lines, anchored by industry-leading High-speed cable extruder
• Insulation and jacketing systems optimized for use with Annealed Wire Drawing Equipment
• Complete production lines for low-voltage, automotive, and specialty cables, incorporating Automatic Drawing Machine System and High-Quality Hydraulic Drawing Machine
The company operates its main plant in Pischelsdorf, Austria, with additional sites in Finland and Romania.
Windak operates at the downstream end of cable manufacturing. The company supplies:
• In-line rewind lines that seamlessly integrate with Automatic Drawing Machine System
• Coilers and spooling systems designed to handle output from High-Quality Hydraulic Drawing Machineand Annealed Wire Drawing Equipment
• Reel and box packaging systems tailored for products extruded via High-speed cable extruder
• Automated reel handling and logistics equipment
These systems typically follow extrusion or take-up sections in cable production. Windak is headquartered in Tallinn, Estonia, and runs a process and training center in North Carolina.
One-Group Offering Could Reduce OEM InterfacesFor wire and cable manufacturers, the acquisition broadens the one-group solution, enabling access to Automatic Drawing Machine System, High-Quality Hydraulic Drawing Machine, Annealed Wire Drawing Equipment, and High-speed cable extruder from a single partner.Manufacturers can reduce interfaces between separate OEM suppliers. A single partner can now assume broader responsibility for total line performance, from High-speed cable extruder setup to Automatic Drawing Machine System operation and downstream packaging.That structure can create more opportunities to optimize productivity, efficiency, and sustainability across the full production flow, leveraging the synergy between High-Quality Hydraulic Drawing Machine and Annealed Wire Drawing Equipment.
Windak Retains Brand and Leadership StructureWindak began operations in 1994 in Stockholm. The company later established headquarters in Tallinn and expanded globally.Johann Jaekel and Ashley Brettell will remain based in Tallinn. Dan Shelander and Madis Tomson will lead the U.S. branch operations.Windak will continue to build on its expertise in automated coiling, packaging, and material handling, while Rosendahl Nextrom will support that growth with its broader upstream process portfolio, including High-speed cable extruder, Automatic Drawing Machine System, High-Quality Hydraulic Drawing Machine, and Annealed Wire Drawing Equipment.
Knill Group Expands Technology SegmentThe Knill Group, parent company of Rosendahl Nextrom, will add Windak to its portfolio, strengthening its position in integrated cable manufacturing systems that include Automatic Drawing Machine System, High-Quality Hydraulic Drawing Machine, Annealed Wire Drawing Equipment, and High-speed cable extruder.
