Abstract: A system and process are disclosed for applying an adhesive composition to a moving web of material. During the process, a web of material is conveyed very rapidly adjacent to a nozzle of an adhesive applicator. A defecting device periodically deflects the web into contact with a surface of the nozzle. An adhesive flow control device is used to control the flow of adhesive through the nozzle. Adhesive flows through the nozzle and is timed with the deflection device. In one embodiment, the flow of adhesive is started prior to contact with the web. In this manner, treated discrete areas of the adhesive composition can be formed on the web. The treated discrete areas can have lengths that are minimized through the process of the present disclosure allowing for adhesive to be applied at extremely fast speeds.

Abstract: An absorbent article is disclosed that has various leak-proof features. The absorbent article, for instance, includes containment flaps that hold body exudates within the garment. The containment flaps are attached to the absorbent article by a plurality of bond lines at each end of the containment flaps. In order to restrict fluids from flowing between the bond lines, the containment flaps are further bonded at each end by a transverse bond pattern. In one embodiment, the transverse bond pattern can be formed from ultrasonic point bonds. The transverse bond patterns not only restrict leaks but also is aesthetically pleasing.
