Edge trimming of steel coils during processing is standard practice, however, unless edge quality can be continuously monitored, the time delay between a deterioration and rectification can result in excessive amounts of rework or even scrap. Unilux have developed Edge Tech, a camera-based system which continuously scans both strip edges and provides immediate display of edge quality to operators. Extensive data and performance analysis algorithms help provide numerical data on trimming knife settings, trimming performance and coil quality.
