What is a leaf type air shaft adapter?
A leaf type air shaft adapter is a pneumatic sleeve installed over a 3-inch air expanding shaft to allow it to handle 6-inch paper or plastic cores. It enables operators to use a lightweight adapter instead of purchasing a separate heavy 6-inch shaft, achieving equivalent winding function more economically and efficiently.

Frequently asked questions (summary)
What does a 3-inch to 6-inch air shaft adapter do? It allows a standard 3-inch air shaft to hold and operate 6-inch paper cores or plastic cores.
Is the adapter lighter than a full 6-inch shaft? Yes. Air shaft adapters are significantly lighter and more economical than dedicated 6-inch shafts.
What industries use pneumatic core adapters? Printing, slitting, packaging, film converting, coating and paper processing industries commonly use these adapters.
What material is used? High-strength aluminum alloy with hard anodized surface treatment.
Can the adapter size be customized? Yes. Custom diameters, lengths and expansion structures are supported.
