Abstract
An apparatus (20) for steering a web (22), including a web path having at least one steering roller (24) and an exit roller (26), each having a mount; wherein the steering roller(s) (26) each have an axis of rotation and wherein the mounts for the steering roller(s) (26) can pivot those axes with a total of two degrees of freedom. An array (30) comprising a plurality of sensors (30a) for monitoring the position of the web (22) is present connected to a controller so as to determine the position and angular orientation of the web (22). The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web (22) at a particular point along the web path.
