Abstract
An adhesive dispensing module and method of spraying a plurality of droplets of a liquid adhesive includes a dispenser assembly and a nozzle. The nozzle includes a nozzle body, a dispersion baffle, and at least one channel. The nozzle body includes a nozzle outlet for discharging a liquid adhesive and at least partially defines a gas inlet, a gas outlet, and a gas passage extending therebetween. The dispersion baffle is positioned within the gas passage to define a dispersion chamber and a consolidation chamber. The at least one channel extends through the dispersion baffle to fluidly connect the dispersion chamber to the consolidation chamber to restrict the pressurized gas received within the dispersion chamber and distribute the pressurized gas into the consolidation chamber according to a predetermined flow distribution. Thereby, the pressurized gas sprays a plurality of droplets of the liquid adhesive according to a predetermined pattern.
