this auto uncoiler is used to support the coil for roll forming machine

1. Automatic uncoiler is an auxiliary equipment for roll forming machine.
it is composed of feed main machine, hydraulic station and control system.
When it works together with roll forming machine and auto stacker, they make up a completely steel panel production line.

2. The working process is loading coil→expanding to fix the coil→uncoiling→feeding the sheet into roll forming machine.
There is a sensor, to keep uncoiler goes at the same speed as roll forming machine.

3.The advantage for automatic uncoiler is, highly automatic, high producing efficiency, and low labor cost.
