New WideArray edge detectors from AccuWeb automatically detect web edges passing within its detection range up to 18.4 inches wide. When positioned on opposite sides of the web in a center-guiding mode, the WideArray’s detection range is doubled, providing 36.8 inches of highly accurate, fully compensated detection. The WideArray allows operators to change web widths on the fly without the need for complicated, maintenance-prone mechanical edge-seeking devices, thereby speeding make-ready time. Since the WideArray does not require manual recalibration, operators can electronically adjust the guide point anywhere within the detection range through the use of an easy-to-mount remote station.
The new detectors feature AccuWeb’s patented compensated array technology that automatically compensates for web flutter and pass-line variances, changes in temperature and humidity, as well as the effects of dust, dirt and other environmental factors. This technology assures precision guiding while eliminating the need for continuous maintenance or potential downtime. WideArray edge detectors are available in both ultrasonic and infrared models to fit every web printing or converting application.
