Abstract (en)
A method for controlling a tension of a continuous web (W) comprises: moving said web along a web path; controlling a first actuator of a first dancer mechanism (100) to generate a first force to move first rollers (110) of said first dancer mechanism (100) along a respective first path on a respective first surface, said first rollers contacting said web at a first portion of said web path; and controlling a second actuator of a second dancer mechanism (200) to generate a second force to move second rollers of said second dancer mechanism along a respective second path on a respective second surface, said second rollers (120) contacting said web at a second portion of said web path, said second portion being separate from said first portion. Said first force and second force are determined so that the tension of said web is substantially equal near said first portion and near said second portion.
