Claims

[Scope of utility model registration request]

The outer diameter of the paper web is predetermined in a shaft braking device that controls the tension of the running paper fed out from the paper web mounted on the support shaft of the paper feeding device of a rotary press by adjusting the brake torque acting on the support shaft. When applying a brake for a sudden stop when the diameter is larger than the specified diameter, in a tension control device equipped with an outer brake device that acts on the outer circumferential surface of the web and generates a braking torque, the outer circumferential brake device is a tension controller that is in contact with the outer circumferential surface of the web. A tension control device characterized by being provided with a band or brush that elastically generates a braking force.
