Abstract:
A method and devices for dispensing adhesive onto an elastic strand are configured to apply first, second, and third volumes of adhesive onto first, second, and third portions of the elastic strand, respectively. When the elastic strand is adhesively secured to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive or a stronger adhesive material capable of limiting movement of the strand at the opposing ends. The method and devices advantageously use a module and nozzle which maintain separation between first and second adhesive streams received from different adhesive supplies at least until flow within the nozzle. This arrangement enables use of different adhesives to form the first, second, and third volumes, as well as “wet-on-wet” contact dispensing using multiple nozzle outlets.
