New compact coat weight system for adhesive measurement on coating and laminating lines
Nordson Measurement & Control Solutions developed a new compact coat weight system – CW 9000, for accurate and fast adhesive coat weight and mix ratio measurements of flexible packaging manufactured on coating and laminating lines.
CW 9000 scanner
At the heart of the CW 9000 gauge is Nordson’s infrared sensor engine. Fast bi-directional scanning updates at the end of each scan with maximum coverage of production run. Unique infrared optics are coupled with advanced algorithms to achieve measurement resolution and performance meeting the quality demands of flexible packaging industry.
With CW 9000, key quality indicators can be seen at a glance – coat weight and mix ratio profiles are available after a single scan. A trend display shows if the coating goes outside of tolerance to enable corrective actions before a problem appears.

The sensor helps to shorten startup time, reduce scrap and minimize adhesive usage while maintaining product quality.
Applications include clear films, printed films, aluminum foils, as well as metalized film or paper. The sensor is highly flexible and capable of measuring other coatings besides polyurethane.
More on the system
The system is built upon Nordson’s proven Pro.Net Total Distributed Intelligence system. It includes the new compact CW 9000 sensor combined with the new LPS 1000 Scanner.
The LPS 1000 is a self-contained Low-Profile Scanner that fits inside the frame off compact coating machines. It can perform fast scans and analyze machine direction variations. The enclosed scanning frame prevents dirt from the scanner from falling onto the coating. Precise motor/drive system also delivers optimal positioning.
The Pro.Net user interface provides real-time process quality, automatic coat weight control and alarms. The display is user-configurable, supporting multiple informative display boxes, such as trends, zone data, zone statistics, roll statistics and historical coat weight via colored profile/3D map, all on a single high-resolution screen.
The system also supports multiple recipes and selectable reporting tools. Last but not least, it features an embedded OPC-UA communication package to export/import valuable data and information.
