A system for dispensing liquid material onto a moving substrate includes a liquid dispenser fluidly connected to a source of liquid material and a source of pressurized air. The liquid dispenser includes a pair of outer liquid material outlets and a plurality of inner liquid material outlets therebetween spaced along a common axis at one end of the dispenser for dispensing a plurality of strands of liquid material toward the substrate. The liquid dispenser further includes a pair of air outlets associated with each of the inner liquid material outlets and a single air outlet associated with each of the outer liquid material outlets for emitting pressurized air that is operable to oscillate the dispensed strands in directions predominantly parallel with the common axis of the liquid material outlets during flight toward the substrate to form an overlapping pattern of liquid material on the moving substrate. Methods for dispensing liquid material onto a moving substrate are also disclosed.
