What is the difference between the circular knife cutting methods of the slitting machine?

Circular knife shearing and circular knife pressure cutting. Circular knife shearing is made by rotating the outer circular tangent points of the upper and lower circular knives to achieve a continuous shearing state. The slit material enters from the tangent direction of the tangent point, and the material is Cut lengthwise. Materials cut with circular knives have clean cuts. It is critical to adjust the coordination of the upper and lower circular knives during use and installation. In round knife pressure cutting, the round knife is pressed directly on the material, and the pressure of the round knife is used to press and cut the material, similar to the principle of cutting vegetables with a kitchen knife. This cutting method is only used in some specific industries, such as paper, tape, non-woven fabrics and other industries.
