Underfeed Rewinder in Paper Production Line

The underfeed rewinder is a vital machine at the end of the paper making line. It takes the full-width paper rolls from the paper machine and rewinds them into finished rolls with the right width, diameter, and tightness. Our underfeed rewinder is a shaftless, double bottom roll type. This underfeed rewinder uses a modular design for easy observation and simple operation. The main drives are placed directly on the floor to reduce vibration. The unwind, slitting, and rewind sections have independent foundations, so vibration does not transfer. The slitting knives use a single motor drive with pneumatic positioning for quick size changes. Also, the two bottom rolls have different masses to lower resonance. These features make our underfeed rewinder very stable and efficient.
