Slitting

Optimized & Industry-ready Solutions

For All Your Complicated Needs

Slitting involves cutting large log rolls of adhesive tape to a specified width. CGS has the custom tape slitting capabilities to convert various flexible materials and pressure sensitive adhesive tape to a customized width.

We use different styles of slitting machines, all of which are equipped with computer-controlled servomotors, allowing us to be able to make the most efficient use of materials. Thus, we can maintain a high standard of quality and provide the best solution for our customers.

01.

Lathe Slitting

Lathe slitting, also known as baloney or single-knife slitting, is a precise and efficient converting method ideal for short runs and fast setups. In this process, master rolls are clamped and rotated on a horizontal shaft, while a sharp, circular blade moves into the spinning roll to cut it into narrower widths. This method offers clean, consistent cuts and allows for excellent control over slit width, making it suitable for high-tolerance requirements.
Thanks to our state-of-the-art equipment, we can slit a wide range of materials, including plastic films such as polyimide, PET, and PTFE, as well as adhesive tapes, laminated materials, and flexible substrates. Lathe slitting is especially useful when working with materials that are sensitive to tension or prone to curling, as the process applies minimal stress to the material during cutting. The result is high-quality, smooth-edged rolls that are ready for use in a wide range of industrial, electrical, and commercial applications.

Rewind Slitting

Rewind slitting, also known as log slitting or roll slitting, is a highly efficient film and tape converting process that produces multiple narrow rolls from a single master roll in one continuous cycle. This method is widely used in industries such as packaging, electronics, insulation, printing, and medical manufacturing. The process begins with the unwinding of a master roll, which is then precisely fed through a set of slitting blades. Once the material is cut to the desired width, each slit section is rewound onto individual cores, resulting in clean, uniform slit rolls that are ready for downstream processing or distribution.

At CGS, we specialize in a wide range of rewind slitting services for materials such as polyimide films (Kapton®), PTFE, PET, PVC, adhesive tapes, laminates, and specialty substrates. Our advanced slitting machines support various cutting methods, including score slitting, shear slitting, and razor slitting, each tailored to specific material characteristics and performance requirements.

Score slitting involves circular blades that press against a metal mandrel, effectively cutting the material as it is pulled through. This technique is well-suited for materials with variable thicknesses or layered structures. Shear slitting operates like a pair of scissors, using two precisely aligned circular blades that meet at a point to deliver clean, burr-free edges. It is commonly used for paper, aluminum foil, non-wovens, and heavier-gauge films. Razor slitting employs stationary razor blades fixed across the web path. The material is pulled through these blades, producing smooth cuts with minimal dust or distortion. Razor slitting is ideal for thin films, flexible plastics, and materials with consistent thickness.

With tight tolerance control, clean edge quality, and fast turnaround times, rewind slitting offers manufacturers a cost-effective solution for preparing materials in custom widths and roll sizes. Whether you need narrow slits, tight core alignment, or bulk roll processing, our slitting capabilities ensure accuracy, efficiency, and material integrity every time.

Benefits of Slitting

Custom Widths for Specific Applications

Slitting allows large rolls to be cut into precise widths tailored for electronics, labeling, insulation, or manufacturing needs.

Improved Handling & Efficiency

Narrower, slit rolls are easier to handle, store, and feed into automated equipment, increasing operational speed and accuracy.

Reduced Waste & Cost

By providing only the size needed, slitting minimizes excess material, reducing both waste and production costs.

Consistent Quality & Clean Edges

High-precision slitting delivers smooth, uniform edges—essential for performance in high-tech or sensitive applications.

Questions

Frequently Asked Questions

What is slitting in film and tape converting?

Slitting is the process of cutting wide rolls of film or tape into narrower rolls with specific widths, often for easier use in manufacturing or application.

What materials can be slit?

Most films and tapes can be slit, including polyimide (Kapton), PTFE, PET, PVC, and specialty adhesive tapes.

How precise is the slitting process?

Modern slitting machines can achieve high-precision cuts with tight tolerances, ensuring consistent roll width and clean edges.

Can I request custom slit widths?

Yes, slitting services typically allow you to choose custom widths based on your application requirements.

Does slitting affect material properties?

No—slitting only changes the width of the material. The film or tape retains its original performance characteristics such as temperature resistance, dielectric strength, or adhesive properties.
