Film Edge Detector Compensates for Dust

An IR edge detector for opaque films and light nonwovens has a new two-beam feature that compensates for dust.

An IR edge detector for opaque films and light nonwovens has a new two-beam feature that compensates for dust. It’s the only dynamically compensated IR edge detector on the market, says the supplier, AccuWeb Inc., Madison, Wis. Normally IR sensors must be kept very clean to be accurate, but this one uses one sensing beam to control the web edge, plus an independent reference head to monitor dust conditions. Subtracting the dust factor from the web signal ensures more accurate web position.


AccuWeb also introduced a wide-array IR edge detector, which provides up to 18.4 in. of detection range so web widths can be changed on the fly. Tel: (888) 422-2893 • www.accuweb.com
