Passive unwinding refers to an unwinding mode in which a magnetic powder brake or a pneumatic brake is used to control the material roll, and the tension between the material roll and the traction device is ensured through a tension sensor or a floating roller. Center rewinding refers to a rewinding mode in which a motor drives the air expansion shaft to collect the material, and the tension between the material roll and the traction device is ensured through a tension sensor or a floating roller. Friction rewinding refers to a rewinding mode in which a motor drives the friction roller and the air expansion shaft to generate friction to collect the material, and the tension between the material roll and the traction device is ensured through a tension sensor or a floating roller.

Defects and shortcomings of the existing technology:

Passive unwinding: Disadvantages: When the diameter of the material roll is large or the weight is heavy, the magnetic powder brake or pneumatic brake cannot control the material roll, resulting in large tension fluctuations.
