A Leaf Type Air Adaptor is used with an air shaft to handle different core sizes while maintaining uniform gripping. It is commonly applied in slitting, rewinding, and unwinding machines in industries like BOPP film, paper, foil, laminates, and flexible packaging where roll quality is important.
The adaptor uses metal leaves (segments) arranged along its body. When air is supplied, these leaves expand evenly around the circumference, creating a continuous contact surface inside the core. This ensures smooth and uniform gripping, reducing point pressure and preventing damage to the core—something that can happen with lug-type systems.
In practical use, a leaf type air adaptor is helpful when frequent size changeovers are required. It allows operators to use the same shaft for different core IDs by simply fitting the adaptor. The uniform expansion also improves tension control and helps achieve better winding results, especially for sensitive or thin materials.
Operation is simple—mount the adaptor on the shaft, insert the core, and apply air pressure. The leaves expand to lock the core securely, and releasing air allows quick removal. This reduces downtime and makes the process more efficient.
Overall, a leaf type air adaptor is a reliable choice when uniform grip, core protection, and consistent winding performance are required in converting operations.
