An innovative device from Dynatech, the Ultra Strand Coating System, now allows for greater efficiency in coating elastic strands with adhesives. The device is designed for use in the disposable personal hygiene sector and allows for faster processing times amounting to 1,400 pads per minute. In addition, a Rapid Change Over feature will speed equipment maintenance processes, while Ultra-stich and Ultra-touch nozzles match various manufacturers’ requirements.
Optimal device lifespan, production line efficiency and the application of the least possible volume of adhesive have all been taken into account. Total creep strength has been reduced to 1%, and the larger nozzles are less likely to block, causing production line hold-ups. The equipment was developed using computational fluid dynamics technology, and has been nominated for an award by the Association of Nonwoven Fabrics Industry (INDA). Dynatech’s systems are implemented on a global scale, particularly in the manufacture of disposable diapers.
