Apparatus and methods are disclosed for spraying an adhesive in a selected pattern on a continuously moving web. The method includes the steps of: (a) supplying a predetermined volumetric flow of adhesive to a nozzle; (b) selectively operating the nozzle between an off position and an on position to spray the volumetric flow of the adhesive; (c) diverting the volumetric flow of the adhesive from the nozzle when the nozzle is operated in the off position; and (d) maintaining a back pressure at the nozzle when the nozzle is operated in the off position to provide a substantially instantaneous spray of the adhesive when the nozzle is operated from the off position to the on position.
