Nordson's SureWrap process for elastic attachment

Published on 2003-08-07. Author : SpecialChem


The SureWrap elastic-attachment process from Nordson Corp. uniformly applies hot melt adhesive to elastic strands using integral-strand guiding and dedicated deposition.

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.

Concentrated delivery of hot melt adhesive fibers to individual elastic strands enhances product-feature elasticity for improved creep resistance. Integral-strand guides stabilize strand position, optimizing adhesive placement and eliminating additional guiding devices. As strands pass through the guides, four radially tangential air jets wrap an adhesive fiber around each strand. Discrete bond points and add-on rates as low as 0.025 grams per coated meter maximize product performance.
