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.

Method for spraying adhesive

Apparatus and methods are disclosed for spraying an adhesive in a selected pattern on a continuously moving web. The apparatus and methods include at least one nozzle which is supplied with a predetermined volumetric flow of adhesive. A pressure regulating mechanism is used to maintain a back pressure at the nozzle when the nozzle is operated in an off position to provide an instantaneous spray of adhesive from the nozzle when the nozzle is operated from the off position to an on position. The nozzle is configured to spray the entire predetermined volumetric flow of adhesive when operated in the on position.
