This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.
press & carry material device:it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.
Accumulator frame assemble:It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.
