Abstract
A system and method for detecting unwanted wrapping of one or more of a plurality of strips of material around a feed roller intended to urge the strips of material forward. During proper operation, the strips of material remain to a first side of the feed roller, but an error may cause the material to pass to a second side of the feed roller. The system for detecting this error may comprise a plurality of send optical fibers configured to send light in a direction toward the second side of the feed roller; a plurality of receive optical fibers configured to receive light reflected off of the feed roller and/or any of the strips of material; and an alarm for notifying a user or an automated system if an amount of light received is not a desired amount of light, indicating reflection off of at least one strip of material.
