Coil slitting machines are essential equipment used to convert wide coils of film, paper, foil, nonwoven, or composite materials into narrower, precisely cut rolls. These machines support packaging, hygiene materials, Printing, laminating, and multiple downstream processes. For manufacturers like Jingwei — whose product range includes high-precision Slitting and rewinding lines — having the right slitting configuration ensures clean edges, stable tension, and high-speed efficiency.

Below are the major types of coil slitting machines commonly used in industrial production.

1. Manual Slitting Machines

These are entry-level slitting units used when production volume is small and adjustments are manually controlled.

Key Characteristics

• Basic tension system

• Manual blade positioning

• Lower speeds compared to automated lines

• Suitable for small workshops or low-volume custom orders

Ideal For

Light-duty materials, small production batches, or facilities upgrading gradually toward automation.

2. Semi-automatic slitting machines

These machines include motorized unwinding, automatic tension control, and easier blade adjustments.

Key Characteristics

• Improved cutting precision

• Higher speed stability

• Pneumatic blade systems may be included

• Suitable for medium-volume production

Ideal For

Manufacturers producing hygiene films, PE packaging film, or laminated materials that require consistent quality but not fully automated operation.

3. Fully Automatic Slitting Machines

These represent the highest level of automation and are widely used in modern film-production plants.

Key Characteristics

• Automated shaft loading and unloading

• Servo-driven tension control

• High-precision slitting with minimal deviation

• Automatic edge trimming and defect detection

• Remote diagnostics and digital control systems

Ideal For

Large-scale film producers, high-speed PE casting lines, breathable film production, and flexible packaging converters — sectors served by Jingwei’s smart slitting solutions.

4. Razor Slitting Machines

Designed for thin and delicate materials where clean cuts are essential.

Key Characteristics

• Razor blades positioned under tension

• Very fine cutting accuracy

• Suitable for extremely thin films

Ideal For

Breathable films, stretch films, and sanitary-grade PE films — materials commonly processed in hygiene-product manufacturing.

5. Shear Slitting Machines

A widely used slitting method where rotating “male” and “female” knives cut the material like scissors.

Key Characteristics

• Clean edges

• Versatile across many material types

• Ideal for thicker films, laminates, and coated materials

Ideal For

Composite films, laminated structures, and packaging rolls produced on extrusion or lamination lines.

6. Score (Crush) Slitting Machines

Designed for medium to thick, nonwoven, and paper-based materials.

Key Characteristics

• A rotating blade presses the material against a hardened anvil

• Simple and durable system

• Works well on tough materials

Ideal For

Nonwoven hygiene substrates, coated paper, foam-based rolls, and sheet-type composites.

7. Duplex Slitter Rewinders

These machines slit and rewind material onto two separate shafts simultaneously.

Key Characteristics

• High productivity

• Excellent for narrow-width rolls

• Commonly used in flexible packaging

Ideal For

High-volume production where consistent roll tension and fast cycle time are required.

8. Turret Slitter Rewinders

A turret system rotates new cores into position while finished rolls are removed automatically.

Key Characteristics

• Continuous slitting capability

• Minimal downtime

• High-speed production

Ideal For

Factories that require uninterrupted output, such as packaging-film producers and hygiene-film lines.

How Jingwei’s Technology Fits These Machine Types

Jingwei supplies high-speed, high-precision slitting and rewinding equipment designed for:

• Breathable microporous film

Final Summary

Coil slitting machines come in various types — manual, semi-automatic, fully automatic, shear, razor, crush, duplex, and turret systems. The ideal machine depends on material type, required precision, production scale, and automation goals. For international manufacturers seeking advanced, stable, and efficient slitting solutions, companies like Jingwei offer integrated, high-performance systems that support modern smart-factory environments.
