A control system for assisting in applying a uniform layer of liquid to a substrate. The control system monitors a fluid pump advantageously integrated directly with an extrusion head. The pump receives the material to be deposited from a remote reservoir and controls dispersion of fluid to the extrusion head. The pump dispense rate is controlled by hydraulic pressure selectively applied by a flow control motor. The control system ensures that a steady-state flow of the liquid is maintained while preventing transient perturbations during initial extrusion startup.

1. A system for extruding material uniformly onto a surface, where the extrusion process is subject to starting and stopping, the system comprising:a pump head for accepting the extrusion material for delivery to the surface; means for selectively directing controlled amounts of accepted material from said pump head to the surface and amounts of said accepted material away from said surface; said selective directing means functionally connected to said pump head; and means for monitoring the amount of extrusion material directed to the surface and monitoring the amount of extrusion material directed away from the surface; said monitoring means functionally connected to said means for selectively directing.
