below is pulling roller and recticiation system 

with line rail that to easy put material on 

Main Features
1. Hydraulic cylinder expands the mandrel that automatically centers the coil.
2. The reinforced spindle is capable of loading the coil more than 5tons.
3. AC Drive and proportional speed control combine to provide smooth material payoff.
4. Equipped with inverter and disc brake, MTC models use a manually adjustable speed control knob to make the operator set the payoff speed.
5. Pneumatic press arm and support arm prevent coil from loosening.

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.
