Abstract
A liquid material dispensing system provides individually metered streams of liquid material to a nozzle or die tip which dispenses the liquid material in a closely spaced arrangement. In one embodiment, the dispensing system utilizes a series of gear pumps to induce the flow of liquid material through individual dispensing modules. An adapter intermediate the modules and the die tip directs the individually controlled streams from a spacing provided by the modules to a close arrangement, such as may be suitable for coating parallel strands of substrate material.
