2. Description of the Related Art Conventionally, for example, when a web-shaped film, paper or the like is continuously fed and subjected to a secondary processing of a certain type and wound up, it is preferable that the tension and the meandering range are always constant. If there were fluctuations before and after secondary processing, the original purpose could often not be achieved. In particular, there are many cases where the feeding speed and the winding speed for secondary processing are different, and it is often necessary to control to a constant tension and meandering range for secondary processing, so effective measures are required. This is the current situation.

As a countermeasure against this, for example, a method of simply slacking (suspending) the film, paper, or the like in a pre-processing step, or a method using a dancer roll is used.
In the former slackening method, when the winding speed such as the feeding speed and the secondary processing speed becomes high, the tension is often unstable and the meandering correction is often disturbed. or,
In the latter method using the dancer roll, when the winding speed is high or when the film is intermittently wound, the inertial force of the dancer roll affects the film, resulting in excessive tension or the moving direction of the roll. However, there is also a problem that the device design is limited because it is limited to the vertical direction.
