Flange safety chuck match with NAB pneumatic brake in unwinding machine
Flange safety chuck is one type of manual safety chuck, it is widely applied in rewinding and unwinding machine for roller material holding. It has FLO/W28, FLO/W35, FLO/W50 and FLO/W75 four models. It is composed of couple, one safety chuck is with an extend shaft, and another one is without extend shaft.

This flange safety chuck is also can be matched with NAB pneumatic brake, manual brake, pneumatic caliper disc brake and etc. They are mainly used in unwinding machine for roller material tension control.

As we know, this NAB pneumatic brake and other brakes are controlled by air, so the air volume determined its braking force. When air pressure larger, then NAB pneumatic brake and other brakes braking force is larger, too, and making roller material unwinding tighter. When air pressure is smaller, then NAB pneumatic brake and other brakes braking force is small, too, and making roller material unwinding smooth. They are usually applied in packing and printing machine.
