Allegro™ Elastic Attachment Nozzles


Patent-pending Allegro nozzles use a novel air-assisted contact coating technology to apply hot melt adhesives to single or multiple elastic strands. This advanced nozzle technology delivers precise adhesive deposition with exceptionally-low variability for elasticized legs, leg cuffs and waist bands on baby diapers, training pants and adult incontinence products.

Integral strand guides stabilize elastic strand positioning while post adhesive-application process air forms molten adhesive around the entire elastic strand. 

Allegro elastic attachment nozzles:

  • Facilitate increased production speeds, up to 650 m/min.
  • Support close center, as near as 2 mm centerlines.
  • Improve creep resistance.
  • Offer durability for easier maintenance and inspection.
  • Stabilize elastic strand position with integral guides.
