AccuWeb Inc., Madison, Wis., has developed a digital infrared (IR) edge detector for guiding webs
including light nonwovens, mesh and paper. An array of IR sensors in the patent-pending device
monitors lateral web position and ambient conditions, and will automatically compensate for
passline variations and web flutter, as well as interference from dust and other contaminants. The
IR detector is compatible with AccuWeb’s Micro 1000® and Micro 4000® NET controllers.
