New Sensor Detects Splices in Film & Foil.

A new sensor using electrical resistance technology helps converters and laminators detect splices in both plastic film and metal foil. Model 4020 Splice Detector from R.K.B. Opto Electronics Inc., Syracuse, N.Y., mounts over a non-rubber-coated roll and detects sudden changes in web material thickness due to mill or butt-type splices. The first production model is at Printpack Inc. in Atlanta. Normally splices are detected with capacitors, photo transistors, lasers, or ultrasonics, but none of these work well with both foil and film, R.K.B. says.
