Offline coater

Highest product quality and stability at maximum productivity: ISRA systems inspect material on the offline coater with high precision, in order to consistently ensure the highest level of quality.

They are specifically designed for high-speed coaters and deliver accurate inspection results even at high operating speeds.

Typically ISRA solutions for off-line coaters consist of the following three system components:

Web Inspection System

This automatic inspection system for all high-quality coated paper and board types reliably detects and classifies edge cracks, holes, dirt spots, wrinkles, streaks, sratches, and in particular coating defects. 

Web Break Monitoring

Live web monitoring and automatically triggered image sequences due to process disturbances help detect critical situations as early as possible and stabilize processes.

Process Stability due to Precise Pinpointing of Detected Defects

Together with the Unwind Control System (UCS), the inspection system precisely combines the inspection data generated in previous process steps with the data obtained from the offline coater.
