Air Score Blade for Slitting Machine : Air score knife is mainly used to slit adhesive tapes. Air blade is cutting tape on the hard roller system driven by pneumatic. This is also known as Crush cut slitting. This process of using brute force to penetrate the slitter blade through a material. The force is applied via a pneumatic knife-blade holder. The slitter blade will be pressed into the material which will be resting on a hardened anvil roll or other similarly tough surface. Crush cut slitting is usually used on very tough materials such as rubbers and sand papers. However, it’s not unusual for more lightweight materials such as tissues and laminates to be subjected to crush cut slitting too. Pneumatic air knives are a reliable and consistent way to position and hold. They are more precise than manual holders. They are durable and can withstand high pressures and temperatures from many pneumatic applications. They are easy to install and use.
