Leaf Type Air Shaft

Leaf Type Air Shaft     • Recommend for rewinding work of narrow roll width, multiple cores or thin-wall cores. • Continuous leaf surface and 360-degree radial contact can provide excellent support  and gripping force to thin wall core, and minimize the core deformation and slip. • According to customer’s demand, the leaf can be aluminum or…

Centering Multi Bladder Type

Centering Multi Bladder Type   • Recommend for rewinding/unwinding which requires high precision on diameter. • Suitable for the operation with core tubes in different length. • Two stage expansion- expand first for centering, then gripping. • No roll loping. • Reduces core vibration and machine wearing. • Easy maintenance. Simple bladder replacement takes less than…

Coreless Type

Coreless Type • For coreless winding. Apply to shrink film, landscape film, rubber roofing, plastic fencing or netting, and all other material. • Green technology. Eliminate the disposal of core and save the cost for core. • High production efficiency. No need for taping the web to the shaft. The changeover time is minimized. • Cantilever…
