Great Success for ISRA PARSYTEC: large order for web inspection
and web break monitoring

Fast Inspection for largest Board Machine

Once again ISRA PARSYTEC is able to announce a big success: Bohui Paper has ordered an integrated ISRA PARSYTEC solution consisting of a web inspection system (WIS) and a web break monitoring system (WBM) for one of the world’s largest and newest cardboard manufacturing machines. The Chinese company found the perfect answer to the increasingly demanding requirements placed on the quality of cardboard packaging.

In addition, Bohui is able to ensure the maximum possible degree of production efficiency, by analyzing web breaks within the mill and developing strategies to avoid them. ISRA PARSYTEC proves its world market leadership by installing the solution and ready to be used in summer of 2012.


As the world’s web inspection market leader, ISRA PARSYTEC continues to be successful in Asia. ISRA PARSYTEC received a large order from Shandong Bohui Paper Co., Ltd. Bohui, located about an hour south of Beijing by plane in the heart of the commercially progressive province of Shandong, is the home of Shandong Bohui Paper Co., Ltd., which was founded in 1994. The company, one of the largest paper and cardboard manufacturers in China, owns one of the world’s largest machines for the production of coated cardboard (for folded cartons), with a reel width of 8,6 m and machine speed of more than 1.200 mpm which is regarded as the benchmark for the global paper industry.

There are currently only three other paper machines of this size in the whole world, all of them installed in China. The expectations placed on the quality of paper and cardboard are rising significantly - even in the growing Chinese market. Even small deviations or surface defects result in a reduction of value. For cardboard manufacturers, it is essential to detect defects as early as possible, to avoid expensive customer complaints. It is equally important to reduce unplanned machine down times and web breaks need to be analyzed instantly and the cause removed.


Reliable identification of defects which are difficult
to detect even for the expert eye

For these reasons, Bohui Paper placed an order with ISRA PARSYTEC in August 2011, to equip the cardboard manufacturing machinery with a web inspection system (WIS) and an integrated web break monitoring system (WBM). The solutions will be installed and ready for use in the summer of 2012.

The WIS reliably identifies all defects during cardboard production with extremely high resolution. The decisive factors for the high acceptance and the top performance of the systems are their unique real-time capabilities, as well as their robustness and reliability. High speed cameras with extremely high resolution are applied. These capture the images significantly quicker than those of competing systems. The pioneering and robust software algorithms guarantee extremely precise inspection results. The inspection of the coated surfaces by their reflection properties and the monitoring of the lower surface for holes and structural deformities are carried out with a single high-power LED lighting bar. A decisive advantage of this inspection equipment is the reliable, precise detection of all surface defects. In this way, it is possible to ensure that only fault-free cardboard is released into the printing process.

The web inspection systems measure, analyze and classify all defects automatically. The defects are identified, classified and recorded, then documented in defect statistics, audit records and images of identified defects saved.


WIS and WBM as an integrated solution

The Bohui machinery gains even more benefits from the integration of the inspection system (WIS) with the web break monitoring system (WBM). The IntelliCam-Cameras producing crystal clear images are installed at 24 important process positions in the paper machine – starting at the materials exit point and continuing through to the final rolling machine. This implies that Bohui can systematically monitor the individual production steps. Defects can be analyzed effectively and causes for defects quickly and reliably determined, corrected and also documented. It also facilitates their precise analysis and the conclusions about the development of defects within the equipment. The entire process chain can be monitored and all causes of defects identified with certainty.

A wide range of valuable tools for process analysis and optimization complement the inspection system to create a complete data and process management solution, which looks after the optimization activities throughout the entire process chain.


Added value and sustainability through process optimization

The modern inspection system makes it possible for Bohui Paper to achieve added value as well as sustainability through process optimization. ISRA PARSYTEC thus significantly improves the competitiveness of the cardboard producer, by increasing the product quality and the effectiveness of production. The entire process chain is monitored and all defects identified with certainty. Thanks to this efficient inspection solution, Bohui profits not only through an improved monitoring of the paper quality produced, but also through product optimization along the entire process chain.

ISRA PARSYTEC was able to win a major contract in the world-wide paper industry. The ISRA PARSYTEC experts understand the high requirements set for the manufacturing of cardboard and paper and know how to maximize yields with web inspection.
