The Lug Type Air Expanding Shaft is a robust and reliable solution designed for efficient core gripping in slitting, rewinding, and unwinding applications. Featuring precision-engineered lugs, this shaft expands uniformly when air is applied, providing strong and secure grip inside the core. It is especially suitable for heavy-duty applications and handling thicker or harder cores in industries such as paper, plastic films, foil, and flexible packaging.
Multi-bladder Aluminium Shaft
Operator-friendly due to their lightweight aluminium construction,
these shafts can be used for light to medium weight winding operations.
Multiple rolls can be wound simultaneously on the same shaft.
Multi-bladder Steel Shaft
Due to their steel construction, these shafts can be used for heavy-duty
winding operations. Multiple rolls can be wound simultaneously on the
same shaft.
• Perfect for roll unwinding and rewinding process
• Body material aluminium with hard Anodized and
Steel (NITRIDING STEEL|41CRALMO7 ) with Hardchrome re grinding or Electroless nickel platting
• Fortune Centrimax system ensures high precision reel centering to guarantee perfectly concentric unwinding and rewinding. Perfect concentricity allows faster machine speeds and reduces stress on the web material.

An Air Valve for Air Shaft is a critical component used to control the inflation and deflation of air expanding shafts in various web handling applications such as slitting, rewinding, and unwinding machines. Designed for precision and durability, these valves ensure efficient air flow management, allowing quick inflation for secure core gripping and easy deflation for smooth roll removal. Manufactured using high-quality materials, air shaft valves offer leak-proof performance, long service life, and reliable operation in demanding industrial environments. Widely used in packaging, paper, plastic, and converting industries, these valves are easy to install, maintain, and compatible with different types of air shafts. Choosing a high-performance air valve enhances the overall efficiency and productivity of your machinery.
The FORTUNE ROTO CONTROL Leaf Air Shafts are thoughtfully designed and recommended for use with thin-walled cores or narrow cores. Our leaf type air shafts have a wide array of applications and can be used with thin-walled paper, steel, plastic, or fiber cores. FORTUNE’s Leaf Shafts are cost effective and lightweight - delivering impressive performance for you operations..
• Leaf-style design delivers more winding surface, and is best for the elimination of thin wall core deformation
The Cantilevered Type / Strip Type Air Expanding Shaft is specially designed for efficient and reliable core gripping in slitting, rewinding, and unwinding applications where one-side support (cantilever mounting) is required. Featuring a strip-type expansion mechanism, the shaft ensures uniform gripping across the core, providing superior torque transmission and preventing slippage during high-speed operations. Its cantilevered design allows quick roll loading and unloading, improving operational efficiency and reducing downtime. Suitable for handling materials like paper, film, foil, and laminates, this air shaft is widely used in flexible packaging, printing, and converting industries. Built with precision engineering and robust construction, it offers long service life, low maintenance, and consistent performance in demanding industrial environments.
The Rubber Tube Lug Type Air Expanding Shaft is a highly efficient and durable solution designed for secure core gripping in various web handling applications such as slitting, rewinding, and unwinding processes. Equipped with a high-quality rubber tube expansion system, this shaft ensures uniform gripping force across the core, providing excellent torque transmission and minimizing slippage during high-speed operations. The lug-type construction enhances strength and reliability, making it ideal for handling paper, foil, and flexible packaging materials. Engineered for precision and long service life, this air shaft offers easy installation, low maintenance, and consistent performance, making it a preferred choice for modern converting industries.
A Cantilever Air Shaft is a specialized shaft designed for easy roll loading and unloading without the need for support on both ends. It is widely used in applications where quick changeovers and efficient handling of rolls are required, such as in slitting, rewinding, and unwinding processes. The shaft operates by inflating an internal bladder, which expands to grip the core securely, ensuring stable and precise web handling.
At Fortune Roto Control, we provide high-performance Cantilever Air Shafts engineered for durability, reliability, and ease of use. Our shafts are designed to improve operational efficiency, reduce downtime, and meet the demanding needs of modern industrial applications.
The 1 Inch Multi-Bladder Air Shaft is a precision-engineered solution designed for secure and uniform core gripping in slitting, rewinding, and converting applications. Featuring multiple inflatable bladders, it ensures even air distribution across the core, providing superior grip strength while minimizing core damage and slippage. Ideal for handling lightweight and narrow rolls, this air shaft enhances machine efficiency, ensures smooth operation at high speeds, and reduces downtime. Manufactured using high-quality materials for durability and long service life, it is widely used in industries such as flexible packaging, paper, and film processing, making it a reliable choice for consistent and high-performance roll handling.
