Quick Answer:
Short Answer
Seconds to minutes per width change with moving sensors. Roll-2-Roll® Sensors adjust instantly (milliseconds).
Every width change with traditional moving sensor center guides requires waiting for mechanical positioners to reposition both sensors to the new edge locations. Depending on the distance to travel and motor speed, this can take several seconds to over a minute per changeover. For converters running short production runs with 10-20 width changes per shift, this accumulated downtime can total 30+ minutes daily. Roll-2-Roll wide Roll-2-Roll® Sensors handle width changes electronically in milliseconds with zero repositioning delay.
