The Erhardt+Leimer Group has been using inspection cameras for guiding, web viewing and inspection technologies for over 30 years. The companies’ expertise ranges from hardware development of cameras controllers, trigger boards and lighting technologies, software development for detection algorithms, defect classifications and HMI interfaces, to application implementation and machine integration into varies processes of web and sheet fed industries. This expertise has now been integrated into the world of Corrugating by utilizing proven hardware and software packages and applying them to Corrugating Converting and machinery, such as Printing Machines, Die Cutters, Gluers and Folders as well as Inline Boxmaker machines. The applications range from Print Inspection of print quality, color drift, defects, hickies, scratches etc. “Print to Die Cut Accuracy”, Glue Application Inspection and Manufacturers Gap Inspection of the folded box.


The ELCorrVision-Pattern system automatically inspects the complex shapes, print and die-cut patterns of box production to ensure repeatable quality in the production of corrugated sheets and in the conversion into the finished box processes. Our high-resolution colour camera can be stationary mounted to inspect a defined area or integrated in a moving support to allow full width inspection. Depending upon application requirements, the ELCorrVision-Pattern can be configured with multiple cameras to increase the number of repeats inspected and / or to increase the resolution of the faults being detected. The ELCorrVision-Pattern uses a master template to determine deviation of product quality from the master template. The system is programmable, ensuring action is taken if target tolerances are not achieved. Output signals are available, enabling defective sheets to be removed automatically at a number of process points, or manually, upon an alarm signal with data logging of defective sheets being a further possibility.


Area of use

The ELCorrVision-Pattern system ensures an automatic inspection of various print and die cut patterns in the Corrugating-Converting.



Applicable in both, corrugators and converters at various positions depending on machine specification.
