Core Shafts

Piu Informazioni

Core 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.

  • 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).

Mechanical and Pneumatic Mechanical Core Shafts
Pneumatic/Mechanical and Fully Mechanical Core Shafts (for high-speed and/or heavyweight winding applications)
 
  • Mechanical operation for strongest grip.
  • Intended for aggressive applications where rolls are heavy and line speeds are fast.
  • Independent lug action accommodates core variations.
  • Concentric expansion reduces vibration and roll bounce.
  • Roll security is guaranteed because of fail-safe design.
