Overview: What the Tecnau U9 Roll Unwinder Does
The Tecnau U9 paper unwinder performs one critical task exceptionally well—maintaining constant, precise web tension as large paper rolls are fed into a continuous-feed inkjet press.
Core functions include:
- Feeding large-diameter paper rolls smoothly into digital inkjet presses
- Maintaining consistent web tension regardless of roll diameter
- Buffering speed differences between upstream roll handling and the press
- Supporting non-stop production with stable, predictable web delivery
This makes the Tecnau U9 Unwinder an essential component in high-volume inkjet environments where consistency and throughput are non-negotiable.
Tecnau U9 Unwinder – Key Capabilities
- High-speed operation suitable for modern colour inkjet presses

- Automatic, closed-loop tension control for consistent print quality
- Wide media compatibility (coated and uncoated stocks)
- Supports multiple core sizes (commonly 3″, 5″, and 6″)
- Designed for large roll diameters to reduce roll changes and downtime

Where the Tecnau U9 Unwinder Fits in the Production Line
The Tecnau U9 Unwinder is positioned upstream of the digital press and forms the foundation of a roll-to-sheet or roll-to-roll system:
Roll → Tecnau U9 Unwinder → Digital Inkjet Press → Cutter / Merger / Stacker
It is commonly paired with Tecnau cutter and stacker systems (such as C-series cutters and S-series stackers) to create a complete roll-to-sheet finishing line.
Why the Tecnau U9 Unwinder Matters
In high-volume inkjet production, the unwinder sets the tone for everything downstream. Poor web control leads to print defects, press stoppages, and finishing inaccuracies. The Tecnau U9 is built to remove that risk by delivering stable tension control and reliable feeding—shift after shift.
Compared to basic roll stands or entry-level unwinders, the U9 provides the active tension management and buffering required for today’s high-speed inkjet presses.
