The Model 714/MZ-A is recommended for unwinding and rewinding where perfect core centering is needed.

It is superior for higher weight, speed, and torque requirements, specially with steel cores.

The body of the chuck and the expandors (leafs) are available in steel only.

The chuck is available in flange or shaft extension type mounting, always custom-made.

Expansion is accomplished by one (or more) air activated pistons that mechanically engage the expandors.
Expansion can be spring-activated so as to grant core is gripped also in case of air leakage in the machine.

The exclusive SVECOM selfexpanding system (activated through the web tension), combined with the pneumaticmechanical system, causes a further expansion of the leafs and ensures a perfect core gripping also in case of heavy duty applications, such as very quick emergency stop.
Standard sizes available for this Model are listed on the download-sheet, but are available in other sizes for a custom order.
