Code marking occurs immediately following the dry-end WebInspector® cameras, which detect and record any defects. These defects are saved in a defect map and sent to the winder where its machine direction (MD) position is accurately determined by the code reader. Using the AccuStop™ software, the operator can slow down the winder when there are large defects to prevent breaks. If a defect needs to be removed or patched, the AccuStop software allows the winder to accurately stop at this operator identified defect. This allows quality issues down the converting chain to be eliminated.
AccuStop’s code reading system uses a Dalsa 2k Linea linescan camera to read the code marking provided by the Ryeco coding system. Lighting provided by a synchronized WebLED28 light makes installation easy & flexible, and can be installed up to 500mm (20”) from the sheet. The Accustop™ code reading camera system has been specifically developed to work with the Ryeco code marker to provide accurate & reliable code reading under all winder applications. Multiple units can be used for applications needing both edges measured.
