The Paper Slitter Rewinder Machine is an industrial equipment used for the precision slitting and rewinding of paper-based materials. It is primarily designed for the continuous processing of airlaid paper, wiping paper, absorbent paper, and similar flexible web materials. This equipment integrates unwinding, stable tension control, high-precision slitting, and synchronous rewinding into a single unit.  Its integrated structure achieves a balance between high-speed operation and dimensional consistency. Compared to ordinary slitting equipment, it demonstrates superior stability in handling wide materials, ensuring stable transport of soft papers, and maintaining clean cuts at high speeds. It can maintain slitting accuracy within an operating range of 200–350 m/min. The equipment supports OEM/ODM customization and is suitable for continuous, large-scale production lines.

1. High Speed and Stability

The Paper Slitter Rewinder Machine operates at speeds of 200–350 m/min, maintaining stable material handling through multi-axis synchronous control in the high-speed range. Both unwinding and rewinding diameters support Φ1500mm, reducing the frequency of roll changes and increasing effective production time per shift, suitable for stable operation in continuous production environments.

2. Slitting Accuracy

Utilizing an independent knife shaft structure and a closed-loop tension control system, the slitting width error is stably controlled within ±0.3mm. Even when processing soft or fluffy paper materials, it ensures clean edges, reducing subsequent rewinding deviations and inconsistencies in finished product specifications.

3. Tension Control

The machine is equipped with a multi-stage tension adjustment module, which automatically matches tension parameters based on material weight and thickness. For low-strength materials such as airlaid paper, tension fluctuations are controlled within ±5%, effectively preventing stretching deformation, wrinkling, or paper breakage.

4. Material Compatibility

The Paper Slitter Rewinder Machine is compatible with materials up to 1700mm in width and can process airlaid paper, wiping paper, tissue paper, and composite paper materials. It offers stable adaptability to materials of different densities and surface structures, reducing adjustment time when changing materials.

5. Consistent Rewinding

The rewinding system employs constant diameter control logic, resulting in a finished roll diameter consistency deviation of less than ±1%. It maintains a flat roll surface even under large-diameter rewinding conditions, facilitating standardized operations in subsequent packaging, dispensing, and transportation processes.

1. Airlaid Nonwoven Paper

In airlaid nonwoven paper production lines, the Paper Slitter Rewinder Machine is primarily used to slit large parent rolls and rewind them to target specifications. The equipment maintains high-speed slitting under low tension, effectively reducing the risk of fiber structure damage and ensuring consistent water absorption performance and finished product dimensions, making it suitable for continuous mass production.

2. Wiping Paper Processing

In industrial wiping paper processing, this equipment is used to slit wide rolls of base paper into multiple finished rolls of various specifications. Through stable slitting accuracy and synchronized rewinding control, it can be directly integrated with automatic packaging or dispensing processes, reducing manual intervention and improving the overall efficiency and consistency of the processing line.

3. Sanitary Paper

For sanitary paper production processes, the Paper Slitter Rewinder Machine can perform high-speed slitting and rewinding while maintaining the flatness of the paper surface. The uniform rewinding tension facilitates smooth integration with subsequent cutting, perforating, or embossing processes, thereby improving overall production speed and operational stability.

4. Absorbent Materials

In the processing of absorbent paper and composite absorbent materials, this equipment is mainly used for size adjustment and finished product rewinding. Stable slitting accuracy helps control the dimensional error of the final product, allowing the finished product to better meet the requirements for dimensional consistency and batch stability in medical, cleaning, and other application scenarios.

5. Paper Product Packaging and Reprocessing

In paper product packaging and reprocessing factories, the Paper Slitter Rewinder Machine can be used as an intermediate process equipment to achieve rapid conversion from large rolls to small rolls. The equipment supports parallel rewinding operations of multiple specifications, facilitating flexible production planning and improving equipment utilization and overall workshop output efficiency.

Q: Is this Paper Slitter Rewinder Machine suitable for processing low-strength paper?

A: The equipment features an independent tension control system designed for low-strength paper, controlling tension fluctuations within ±5%, effectively preventing tearing and wrinkling. It maintains stable operation even when processing soft materials such as airlaid paper.

Q: Is complex machine adjustment required when switching between different materials?

A: The equipment supports parameterized settings, allowing for quick switching between different materials using preset tension and speed parameters. Under normal circumstances, the adjustment time after material change can be kept to a minimum, facilitating continuous production of multiple product types.

Q: Can the slitting width be customized according to requirements?

A: The equipment supports multi-specification slitting configurations. The cutter layout and slitting width can be adjusted according to finished product requirements, adapting to different paper product sizes and reducing subsequent cutting or rework.

Q: Is the rewound finished product prone to loosening during transportation?

A: The rewinding system uses constant diameter and tension collaborative control, resulting in uniform tightness of the finished rolls, with a diameter deviation of less than ±1%. Under normal transportation and storage conditions, loosening or deformation is unlikely.

Q: Does it support OEM or customized configurations?

A: The Paper Slitter Rewinder Machine supports OEM/ODM services and can be customized according to production line layout, material specifications, and capacity requirements, making it suitable for project-based procurement and large-scale production.
