A Lug Type Air Shaft is one of the most commonly used shafts in slitting, rewinding, and unwinding machines for handling cores in industries like paper, film, foil, laminates, and flexible packaging.
The shaft works on a simple air expansion system. It has rubber lugs fitted along the body, and when air is supplied, these lugs expand outward to grip the inner diameter of the core. This creates a strong mechanical hold, ensuring the core does not slip during rotation. When the air is released, the lugs retract back, allowing easy removal of the रोल.
In practical use, lug type air shafts are suitable for general applications where consistent grip and reliable performance are required. They are widely used in BOPP film lines, paper mills, and converting machines where moderate to high speeds are involved. The gripping is firm, but slightly point-based (at lug positions), which works well for standard cores.
One of the main advantages is its simple design and easy maintenance. The shaft is rugged, cost-effective, and can handle continuous industrial use without frequent issues. Loading and unloading cores is quick, which helps reduce machine downtime during roll changes.
Overall, a lug type air shaft is a dependable and widely preferred solution for everyday slitting and rewinding operations where ease of use, durability, and consistent performance are important.
