Core Shafts
Piu InformazioniCore shafts are used throughout the converting and packaging industries to unwind and rewind web material. Winding shafts usually expand to grip the inner diameter of a core to help control web tension.
Double E offers the right core shaft for your converting application.

DLB-2000 Carbon Fibre Expanding Core Shafts
For Unwind and Rewind Applications
CF-1000 Carbon Fibre Through Shafts
(Non-expanding core shafts are available
for through-roll support using air chucks)
- Carbon fibre shaft body provides the strength of steel at a fraction of the weight.
- Proprietary corded polyprene internal bladder expands with air to force the lugs to grip the inner diameter of the core. The special bladder material reduces bladder failure and minimizes maintenance.
- Deep journal insertion and a close tolerance fit provide a high-strength connnection, yet ensures easy maintenance access when necessary.
- Comprehensive two year warranty even includes bladder (most applications).
