Abstract
A dispensing system comprising first and second valve modules each having an output for delivering a liquid under pressure, a nozzle assembly coupled to the first and second valve modules, the nozzle assembly having at least two separated, at least partially coextensive outputs respectively communicating independently with the outputs of the first and second valve modules. A nozzle assembly adapted to be coupled to first and second valve modules each having an output for delivering a liquid under pressure, the nozzle assembly having two liquid inputs and at least two separated, at least partially coextensive outputs respectively communicating independently with the two liquid inputs, and the two liquid inputs adapted to be coupled in communication with the outputs of the first and second valve modules. A method of extruding a liquid, comprising delivering the liquid to two separated, at least partially coextensive outputs of a nozzle assembly, discharging the liquid from the outputs, and combining the discharged liquid on a substrate.
