Carpet Web Detection
Determining the location of the two edge transitions on carpet web is important in carpet manufacturing: air to selvage and selvage to tufting.
It's much easier and more cost-effective to measure and monitor these transitions while the web is running than risk expensive waste in post-manufacturing inspections.
As the carpet web passes through a pair of EZ-ARRAY measuring light curtains, the two sticks configured for Nap Detection mode monitor the process in action. The EZ-ARRAY detects the selvage edge and tufting edge and sends data to the web control system, which can then make necessary adjustments to keep the carpet in line.
