Hunkeler RW7 Rewinder – Efficient, Heavy-Duty Paper Processing Solution

Introducing the Hunkeler RW7 Rewinder, a high-performance solution designed to handle continuous paper web processing in commercial printing environments. Ideal for companies looking to streamline post-printing processes, the RW7 Rewinder integrates seamlessly with the Hunkeler Print Online Paper Processing System (POPP) and is specifically built for rewinding printed paper webs.

Engineered to offer precision and reliability, the Hunkeler RW7 is perfect for commercial printers, mailrooms, and large-scale finishing operations where constant web tension and accurate rewinding are critical.

Key Features and Benefits

• Heavy-Duty Rewinding: The RW7 can handle rolls with a maximum diameter of 54 inches, ensuring that even high-volume print jobs are processed efficiently.
• Easy Operation: With its operator-friendly touch panel and automatic dancer lift, the RW7 simplifies the process of rewinding, reducing downtime and increasing productivity.
• Precise Web Tension Control: The RW7 maintains constant web tension through a non-slip brake unit, ensuring tight, straight-edge rolls every time.
• Versatile Paper Handling: The RW7 can process a wide range of paper weights (from 40 to 300 g/m²) and roll widths, accommodating both lightweight and heavyweight paper with ease.
• Flexible Roll Direction: Rolls can be rewound in either direction, providing flexibility based on your specific finishing or post-processing needs.

 
Built for Maximum Efficiency

The Hunkeler RW7 Rewinder features an electro-mechanical roll lifting system, making it simple for operators to manage and position rolls with minimal effort. Once the paper web is manually introduced, the module’s automatic initialization takes over, allowing for a smooth, consistent rewinding process.

The triple dancer system ensures clean paper web contact, even during high-speed operations, making it an ideal choice for businesses requiring fast, precise rewinding with minimal errors.
