ABSTRACT:
The patterning and blending system according to this invention superimposes two or more lateral channels distributing diverse liquids over a multitude of crosswise oriented feeder chambers with the option to block the flow connection completely or to connect each feeder chamber with any or all of the distributor channels by means of a choice of variable type and calibrated connecting orifices for the predetermined combination of proportional liquid streams of constant and repeatable quality, creating either single flow or striated liquid bundles, which in any feeder are identical to preconceived pattern notations, or to blend such liquid combinations homogeneously between distribution section and application plane on a continuous basis and at a choice variable from feeder chamber to feeder chamber and from pattern to pattern, and with means to supply automatically and under pressure a number of liquids to a constant level staging area where gravity/suction forces take over to provide measured and blended flow in sufficient quantities to satisfy demand at all production speeds.
