Mechanical chucks technologies can incur in the incomplete ejection of cores or rolls from the roll stand.

This involves the manual intervention with levers or other tools for the discharge of blocked rolls from the roll stands, which may imply high probability of operator injuries or machine damages and it is not compliant with the Technical Standards ISO 11228 Ergonomic – « Lifting & Carrying’’ and ‘’Handling of loads at high frequency’’.

Duplex, revolutionary core chuck, prevents injuries for the operator as it eliminates the manual intervention and always ensures the automatic discharge of any dimension rolls from the roll stands.
