Until now, visual surface inspection for doctor-blade stripes or other coating defects on sheet or film had to be performed at the end of the line after the coating had cooled or dried and was no longer shiny, reflecting too much light to be easily inspected. New CoatScan TCS (traversing coat scan) from Mahlo GmbH in Germany (U.S. office in Spartanburg, S.C.) is believed to be the first visual inspection system to detect doctor-blade streaks immediately after the coating head, alerting an operator to correct the problem before much material is wasted. The device traverses on a bar 150 mm from the coating head, with defect resolution near 0.1 mm. (864) 576-6288 • www.mahlo.com
