Abstract
A method of temporarily accumulating a web (W) when delivered from a producing machine includes the step of lengthening a vertical path of the web passing over an upper guide (A) downwardly over an oscillator roll (B) on a web takeup driven by a motor (C) controlled by movement of a compensator roll (D) in response to variations in web tension as for avoiding a necessity of stopping the producing machine when doffing a web roll from the takeup.
