Roll & Core Ejection Chuck
The Duplex mandrel presents a revolutionary design that combines a mechanical expanding chuck, equipped with new high-gripping jaws, and a pneumatic telescopic piston that is concentric to the mandrel. This allows to remove blocked cores and remove rolls on every roll stand safely, since the thrust force of the piston is always coaxial to the roll itself.

100% ADAPTABLE TO ALL ROLL STANDS
