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.
