Dukane’s Curved Leg Elastic (CLE) technology redefines how elastic strands are attached in hygiene product manufacturing. By enabling ultrasonic bonding of curved elastics without any hotmelt adhesive, CLE eliminates material waste, simplifies construction, and enhances product performance. For the first time, manufacturers can seamlessly integrate curved and straight elastic strands within the same lamination using ultrasonic technology alone—a breakthrough previously thought possible only with adhesives or complex multilayer designs. CLE, which represents a new standard in sustainable, high-precision elastic attachment, is a finalist for the Hygienix 2025 Innovation Award.

Dukan’es hygiene bonding technologies include:
·       Elastic Waistband Module (EWB): Seamlessly integrates into new or existing baby diaper machinery to create waist pouches or waistbands using elastic strands or film, improving fit and comfort.
·       Rigid Acoustical Module (RAM): Delivers high-speed, high-performance bonding with tailored durability for hygiene products.
·       Optibonder™: A next-generation bonding solution for nonwoven web materials, offering ultra-high speed and precision with Dukane’s proprietary Active Force Control algorithm, achieving position control of 0.1μm and forces up to 4,000 N.
