2500mm Underfeed Rewinder for Paper Production Line

The Underfeed rewinder is the final key step in the paper making line. It takes the large full-width paper rolls from the main machine and cuts them into finished rolls. These finished rolls have the exact width, diameter, and tightness needed for shipping. It also helps remove any poor-quality paper and fixes broken ends. A reliable Underfeed rewinder ensures your paper production line delivers high-quality rolls with less waste.
Here are the main features of our Underfeed rewinder:
1. It provides constant tension control during the whole rewinding process.
2. The bottom knife speed automatically tracks changes in the paper web speed.
3. It has an automatic slowdown function to keep the system safe when the unwind roll gets small.
4. It has an automatic stop function for both set diameter and set length.
The rider roll pressure is automatically controlled based on the roll diameter. You can set the pressure curves and switch between them for different paper grades.
