A method of adaptive guiding of a web on a roller is disclosed. The method includes computing an output of a reference model, reading an output of a sensor that indicates a web position, determining a difference between the output of the reference model and the output of the sensor, and updating a set off controller parameters for the roller based on the difference.

Method for adaptive guiding of webs

A web edge sensor is disclosed. The web edge sensor has a light source directing light incident to an edge of a web. The edge of the web scatters the light and a sensor array that detects a first portion of the light scattered from the edge of the web and rejects a second portion to determine a position of the web edge.
