BOTTOM KNIFE HOLDING AIR EXPANDING SHAFT

The Bottom Knife Holding Air Expanding Shaft is a high-precision solution designed for efficient slitting operations in slitter rewinder and converting machines. This air shaft is equipped with a bottom knife holding mechanism that ensures stable and accurate cutting performance when used with top knives or razor systems. Featuring a pneumatic expansion system, it provides strong and uniform core gripping, enabling smooth torque transmission and minimizing slippage during high-speed operations. Its robust construction, precise alignment, and vibration-free performance make it ideal for processing materials such as paper, film, foil, and laminates. Widely used in flexible packaging, printing, and converting industries, this shaft enhances productivity, ensures consistent slit quality, and requires minimal maintenance.
