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