DAWSONVILLE, Georgia - November 12, 2003 - The patent-pending OptiStroke needle stroke detection system from Nordson Corporation (Nasdaq - NDSN) verifies valve actuation and fatigue in demanding manufacturing operations that subject hot melt adhesive applicators to performance limits. Online process control monitors needle stroke action in the applicator valve to assure correct adhesive placement, substantially reducing waste while improving product performance.

The OptiStroke system uses optical needle stroke detection to confirm needle travel and measure compensation times. In the event of a no-stroke or slow-stroke fault, an automatic alarm alerts the operator or stops the line to prevent manufacture of scrap product. Diagnostic software tracks performance trends to identify potential valve fatigue before it may affect production.

Parameter adjustment capability and the availability of up to 12 channels that accept multiple configurations meet specific manufacturing requirements. The system is compatible with many Nordson hot melt adhesive modules and features plug-and-play installation.
