At Fortune Roto Control, our Leaf Type Air Shaft is designed to provide smooth, uniform, and reliable core gripping for winding and unwinding applications across various converting industries. The shaft operates through an internal pneumatic bladder system that expands specially designed leaf strips outward, ensuring even pressure distribution throughout the core surface. This advanced gripping mechanism minimizes core damage, improves roll balance, and delivers stable torque transmission during high-speed machine operations. Leaf Type Air Shafts are widely used in paper, film, foil, textile, printing, and flexible packaging industries where precision and smooth performance are essential.
Manufactured using high-quality aluminum or steel construction, the Leaf Type Air Shaft offers excellent durability, lightweight handling, and long operational life under continuous industrial use. Unlike conventional lug-type shafts, the leaf mechanism provides nearly full-surface contact with the core, resulting in better concentricity, reduced vibration, and improved winding quality. The shaft supports quick inflation and deflation, enabling faster roll changes and minimizing production downtime. Its precision-engineered design also helps maintain consistent tension control, making it ideal for sensitive and high-speed web handling applications.
Our Leaf Type Air Shaft is engineered to deliver dependable performance, easy maintenance, and superior operational efficiency in demanding production environments. Available in multiple core sizes, custom lengths, and various mounting configurations, the shaft can be tailored to suit specific machine requirements. At Fortune Roto Control, we are committed to providing innovative and precision-engineered web handling solutions that enhance productivity, improve roll quality, and ensure long-lasting industrial performance.
