Simply replace the tension chuck – and NEPATA rewinders can now also process material on 6-inch cores. The new 6-inch tension chuck makes it possible to perform rewinding on materials such as magnetic foil or stone-chip protection film quickly and efficiently.

Why 6-inch cores?

Some media are supplied by manufacturers exclusively on 6-inch cores, including magnetic foil and stone-chip protection film. Until now, we have offered an adapter for unwinding such rolls, which is fitted onto our 3-inch tension chucks. By contrast, the new 6-inch tension chuck offers two key advantages: it allows for higher speeds and, on some models, also enables rewinding.

Applications and compatibility

The 6-inch tension chuck is fitted to the shaft in place of the standard 3-inch tension chucks:

Conversion in just a few minutes

Switching between the 3-inch and 6-inch tension chucks takes just a few minutes. The following video shows how to fit them.

Also suitable for smaller cores

For media wound onto smaller diameters, we also offer 2-inch and 40-mm tension chucks, as well as matching tension shafts. This allows your NEPATA rewinder to be flexibly adapted to a wide variety of sleeve diameters.
