ABSTRACT:
An arrangement for controlling the flow of fluid in which the fluid is allowed to flow through a selected number of parallel paths of various flow capacities as determined by restricting orifices and cutoff valves. Accurate volume/length of fluid is dispensed at variable velocities by controlling both applicator velocity and flow rate. An arrangement is also provided for controlling the shape of the deposited fluid employing controlled air flow confinement.
