Abstract
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 plurality of liquid material outlets ( ) 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 liquid material outlets ( ) for emitting pressurized air ( ) that is operable to oscillate the dispense 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.
