Product Overview
The Craft/White Paper Roll Slitter Rewinder Machine is designed for slitting and rewinding wide paper rolls into narrower rolls according to required specifications. It integrates roll unwinding, slitting, tension control, and rewinding functions in one machine.
This machine is suitable for processing kraft paper, white paper, and other roll materials that require width adjustment and rewinding before further converting or printing processes. By trimming and rewinding paper rolls, it helps improve roll appearance, edge quality, and usability for subsequent production.
Key Features
- The main machine is driven by a variable frequency motor.
- Single-axis hydraulic winding is used for winding.

FAQ
1. What is a Slitter Rewinder Machine used for?
A Slitter Rewinder Machine is used to slit wide rolls of paper or other roll materials into narrower rolls and rewind them according to required specifications.
2. What materials can this machine process?
It can process kraft paper, white paper, thermal paper, carbonless paper, coated paper, films, aluminum foil, non-woven fabrics, composite materials, and other roll materials within the machine specifications.
3. Why do paper rolls need slitting and rewinding?
Paper rolls may have uneven edges, loose winding, or unsuitable widths after initial production. Slitting and rewinding help adjust roll width, improve edge quality, and prepare rolls for further processing.
4. What is the maximum working speed of this machine?
The working speed of this model is up to 300 m/min.
5. How is paper tension controlled during rewinding?
The machine uses automatic tension control during unwinding to help maintain stable roll processing.
6. What loading method does the machine use?
The machine supports manual assisted loading or shaftless hydraulic loading methods according to configuration requirements.
7. Can the machine process different roll widths?
Yes. The machine can process paper rolls within the specified width range. The maximum paper roll width is 1600 mm, and the minimum paper roll width is 800 mm.
