The current invention is generally directed to apparatuses and methods for controlling tension and tension disturbances in a web being continuously unwound from a roll of spirally wound web material. In accordance with the present disclosure, a rotary dancer mechanism is used for applying active and variable forces to a moving web in response to irregularities, such as variations in tension. In one aspect, the apparatus and method of the present disclosure may be used to attenuate undesired disturbances in the web as the web is being fed into a process.
