In a liquid dispensing system having a dispensing module and a gun manifold, the gun manifold includes a shelf portion that extends outwardly from its front face and the dispensing module includes a correspondingly shaped aperture configured to engage the shelf portion so that the dispensing module rests, or hangs, on the gun manifold without being held into place. From this position, the module can be easily and readily attached to the manifold. The shelf and aperture have complementary shapes and can be keyed so as to require the mating of the manifold and module in only one orientation. Additionally, an adaptor can be provided between the module and manifold so that smooth face manifolds and modules can still be coupled to corresponding manifolds and modules having shelves or apertures.

Method and system for supporting and/or aligning components of a liquid dispensing system

A module or dispenser for dispensing at least one liquid filament onto a moving substrate includes a nozzle body having a liquid supply port, a liquid discharge portion or end, and a liquid discharge passage having an orifice in fluid communication with the liquid supply port. The liquid discharge passage extends along an axis and the opening is shaped asymmetrically about the axis to provide a controlled directional movement of the liquid filament in a desired direction. The asymmetric shape may be formed by a notch or a chamfer or a stepped portion intersecting with the liquid discharge passage, or combinations of these features, or in other manners.
