However, there is no integrated tension device for such production lines. Usually, two sets of tension devices are used to deal with the production lines for the simultaneous production of two rolls. However, the equipment with two sets of tension devices will lead to a bloated overall structure of the equipment. In addition, there are problems such as complex overall structure of the equipment and inconvenient debugging and control.
