High-precision smart cameras with LED strobe light read codes on winders running up to 3000 m/min (9800 ft/min). Code reading is synchronizing different manufacturing steps with each other.
Code marks placed on the web in an upstream process usually indicate a warning to a downstream operator. With a mark reader the marks can be automatically detected and defect map can be synchronized on spot. A mark reader is closing the loop on your defect detection and removal program.
