Abstract
A unique and distinctive adhesive pattern is applied to a base web, such as a nonwoven web. The adhesive pattern can include a plurality of treated discrete areas that can extend parallel in the longitudinal direction of the web. Each treated discrete area can include a head portion connected to a tail portion. The head portion, in one embodiment, can have a greater amount of adhesive composition based on mass per area in relation to the amount of adhesive composition contained in the tail portion. The overall length of the treated discrete area can be relatively short in relation to adhesive patterns produced in the past using conventional slot coating processes. The adhesive pattern provides a secure attachment to an adjoining material and can provide various processing advantages.
