711MA-MECHANICAL SELF-EXPANDING CHUCKS

The Model 711/MA is recommended primarily for unwinding of both steel and cardboard cores.

It is superior for higher weight, speed and grants a perfect core centering.

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

The flange mounting is always custom-made and the chuck can be stepped for use with different core sizes.
The expanding elements, pin-fitted on a cam, are expanded through the reel rotation combined with the web tension.
