Duplex - roll ejector chuck [3D video]

Duplex is one of a kind roll ejector chuck.
Its patented design combines a core chuck and a pneumatic telescopic piston which is concentric to the chuck.
It has been designed to cope with the difficulties that often occur on roll stand and to ensure:
- Automated ejection of every dimension roll even in the case of damaged cores. The piston’s coaxial thrust force of 2000 kg (first stage) + 1000 kg (second and final stage) is applied directly to the roll.
- Higher #safety level during the roll change as it eliminates the manual intervention with levers or other tools for the discharge of jammed rolls
- Best-in-industry #grip to every material core from first phase of work
- Zero paper #waste. By avoiding slippage and lateral damage, rolls can be used up to the last centimeters.
