1. Free cutting (razor blade)
In this process the web materials are subjected to tensile stress by passing the extremely sharp cutting edge of a thin blade. Is the most simple and cost-effective cutting method and the only method for very thin film.

2. Shear cutting
In rotary shear process the web materials are slit in the nip between two overlapping metal disks which create stress in the shear mode to sever the product. Is the most commonly used method, but is the most demanding to control specific operating parameters for high quality slitting.

3. Crush cutting
In this process the web materials are subjected to compressive stress using a rotary tool and anvil. Less cut quality but user fiendly.
