A new edge detector designed to provide web-width and edge position measurements for film extrusion and converting applications features no moving parts and is said to eliminate maintenance. Web Width Monitor from AccuWeb, Inc., Madison, Wis., can accommodate web-width variations of up to 36 in. without moving the edge detector. The system uses patented WideArray edge detectors and a Micro 4000 controller equipped with special software to make accurate web-width and position measurements simultaneously. A three-button remote operator station can be mounted anywhere. A reportedly unique “job recipe” function allows the operator to store and recall tolerance and calibration settings for up to 25 products.
