Duluth, Georgia (PRWEB) August 02, 2012
The new Allegro™ elastic attachment nozzles from Nordson® Corporation (Nasdaq: NDSN) uniformly apply hot melt adhesive to elastic strands using a novel air-assisted contact coating technology for precise adhesive deposition. Concentrated delivery of hot melt adhesive to individual elastic strands enhances bond integrity for improved creep resistance. Applications for single or multi-strand attachment include elasticized legs, leg cuffs and waistbands on disposable nonwovens infant diapers, training pants and adult incontinence products.
The patent-pending Allegro nozzles accommodate high-speed production, speeds up to 650 meters per minute, while supporting elastic centers as close as two millimeters. Integral strand guides stabilize strand position and post adhesive-application process air forms adhesive around each individual elastic strand. Exceptionally-low coating variability is achieved and add-on rates as low as 0.025 grams per coated meter optimize adhesive efficiency and maximize product performance.
The robust design and all-steel construction deliver exceptional durability and resistance to the wear associated with high-speed elastic handling, as well as simplify cleaning and maintenance. And, Allegro nozzles offer a wide operating window, across a variety of process conditions as well as a broad range of elastic and adhesive materials.
Allegro elastic attachment nozzles are compatible with Nordson Universal™ modules. In addition to standard nozzle configurations, special nozzle strand configurations and nozzle lengths up to 175 mm for many-strand applications may be ordered.
