A Leaf Type Air Shaft is used in slitting, rewinding, and unwinding machines where uniform gripping of the core is important, especially for thin or sensitive materials. It is commonly used in industries like BOPP film, paper, foil, laminates, and flexible packaging where रोल quality matters.
The shaft works on an air expansion system, but instead of rubber lugs, it uses metal leaves (strips) arranged along the shaft body. When air is supplied, these leaves expand evenly around the circumference, creating a continuous and uniform gripping surface inside the core. This reduces point pressure and helps avoid core damage, which can happen in lug-type shafts.
In practical use, leaf type air shafts are preferred for applications where smooth and even tension is required across the width. Since the gripping is more uniform, it helps in achieving better winding quality, reducing chances of wrinkles, telescoping, or uneven रोल formation.
Operation is simple—apply air to expand the leaves and lock the core, and release air to remove it quickly. This makes roll changeover fast and easy, saving time during production.
Overall, a leaf type air shaft is a good choice when you need better surface contact, uniform expansion, and improved winding quality, especially for high-speed or precision slitting and rewinding jobs.
