It is used to support tape coil and provide raw materials for production line. The braking mode is controlled by pneumatic brake, which ensures that the strip does not roll loose in the work.

It consists of expanded reel, transmission box body, transmission mechanism, pneumatic drum brake, and centering roller. The motor actively opens the coil head when crossing the coil . When the production line is working continuously, the output shaft of the geared motor is disengaged by the clutch, the motor does not work, and the winding material is driven by the traction leveler or the shearer. The uncoiling tension is provided by the drum brakes.
