Patent ID: 7152815

Claim:
A dispensing system for dispensing a liquid onto a substrate moving in a machine direction, comprising: first and second valve modules respectively including first and second inputs for receiving the liquid and first and second outputs for delivering the liquid under pressure; and a nozzle assembly in fluid communication with said first and second valve modules, said nozzle assembly comprising: a first shim plate defining a first shim output in independent communication with said first liquid output of said first valve module, said first shim output adapted to discharge the liquid onto the substrate in a first pattern extending across at least a portion of the substrate in a cross-machine direction; a second shim plate defining a second shim output in independent communication with said second liquid output of said second valve module, said second shim output adapted to discharge the liquid onto the substrate in a second pattern extending across at least a portion of the substrate in the cross-machine direction, said first shim output at least partially coextensive with said second shim output, said first and second shim outputs capable of selectively discharging the first and second patterns of liquid respectively onto the substrate such that one of the first and second patterns of liquid at least partially overlies the other of the first and second patterns of liquid.
