Nordson Corporation, leading manufacturers of systems used for dispensing adhesives, has launched duet variable dispense applicators to help improve product quality and performance of nonwoven disposable hygiene products.

The patented, dual-module applicators deliver different add-on weights at the ends of an elastic strand than in the middle. This variable add-on produces the high bond strengths needed to secure the ends of elastic to a nonwoven garment while helping retain retractive forces in the center of the elastic strand, Nordson said in a press release.

Applications like elasticized legs, leg cuffs and waistbands on disposable nonwovens infant diapers, training pants, and adult incontinence products are expected to benefit from this new capability.

Duet applicators provide complete adhesive coverage of the entire strand in a single pass using two independently-fed, independently-cycling Speed-Coat modules to optimize adhesive use and deliver excellent cut-off. The lighter add-on weight in the center of the elastic strand provides a stabilizing bond while supporting high-performance elastic features. Meanwhile, heavier add-on weights at the ends of the elastic securely bond the elastic strand to the product to provide durability in use.

The duet applicator is also compatibile with Nordson’s Allergo and SureWrap elastic attachment nozzles, which further improves product quality and optimizes adhesive use. These nozzles use the patented Nordson Universal clamping feature for quick, easy nozzle changes to maximize machine up-time and the patented integral strand guide to stabilize the elastic at the point of application for reliable elastic coating.

Nordson Corporation delivers precision technology solutions that help customers succeed worldwide. The company engineers, manufactures, and markets differentiated products and systems used for precision dispensing of adhesives, coatings, sealants, biomaterials, fluids, and other materials. (GK)
