Types of Slitting Rewinding Machines

Each Slitting Rewinding Machine type offers specific functions based on the material to be processed, production scale, slitting method, and desired automation. Below are the most common types categorized by mechanism and application:

1. Surface Slitter Rewinder Machine

Surface slitting rewinding machines use surface-driven rewind shafts to wind the material. Ideal for medium to low tension materials like nonwoven fabric, laminated film, and paper, these machines ensure even tension and clean winding.

Features:

• Surface winding through drum friction

• Ideal for soft materials

• High-speed performance

• Compact design

Application: Paper rolls, nonwoven, light plastic films.

2. Center Slitter Rewinder Machine

In center rewinders, material is rewound directly onto a shaft driven by a motor. These are often used when consistent roll hardness and precise tension are needed.

Features:

• Rewind shaft is driven independently

• Suitable for high-tension materials

• Precision winding and control

• Optional automation features

Application: Heavy plastic films, laminates, and high-density paper.

3. Center-Surface Slitter Rewinder Machine

Combining both surface and center winding, this hybrid model offers versatility in tension control and roll winding. It is ideal for applications needing variable tension and high roll consistency.

Features:

• Dual-drive system (surface + center)

• Highly versatile

• Used for high-end packaging films and labels

Application: PET film, BOPP, adhesive tape, and flexible packaging.

4. Duplex Slitter Rewinder Machine

The duplex model features two rewind shafts operating in tandem. It’s widely used for general-purpose slitting and offers fast roll changes.

Features:

• Two parallel rewind shafts

• Compact and operator-friendly

• Excellent for medium-speed production

Application: Adhesive tapes, plastic films, and paper.

5. Duplex Turret Slitter Rewinder Machine

A more advanced version of the duplex model, the turret slitter includes rotating shafts that allow non-stop roll changes. This increases efficiency for continuous operations.

Features:

• Non-stop turret winding

• Automated roll changing

• High productivity

Application: Large-scale production of laminated film, tapes, and label stock.

6. Razor Slitting Rewinder Machine

Razor slitting involves sharp blades slicing the material. This method is highly suitable for thin materials where precision is crucial.

Features:

• Razor blade cutting system

• Best for thin plastic film and foil

• Minimal dust generation

Application: Plastic film, thin laminates, foils.

7. Shear Slitting Rewinder Machine

Using two rotary knives that act like scissors, shear slitting delivers smooth, burr-free cuts on thicker materials.

Features:

• High precision

• Works well with thicker materials

• Excellent edge quality

Application: Heavy paper, laminates, metalized film.

8. Score Slitting Rewinder Machine

Also known as crush slitting, score slitting uses a circular knife pressed against a hard anvil. It is suitable for materials like adhesive tape and paper.

Features:

• Economical solution

• Easy blade replacement

• Moderate precision

Application: Paper, adhesive tape, cardboard.
