Abstract
The invention provides apparatus and methods for coiling and uncoiling a metal strip in which the angular position of a coiler is measured and an actuator is provided for a moveable roll, the moveable roll position being varied as a function of the coiler. The present invention aims to avoid tension variations in the metal which cause width and thickness variations in rolling operations for instance.
