ABSTRACT:
A system for mixing first and second polymer melt flows and directing a mixed polymer melt flow to one and another downstream locations includes a control valve having an inlet port for receiving the first polymer melt flow, and a pair of outlet ports, and a fluidic valve for forming the mixed flow of the first and second polymer melt flows and directing the mixed flow to one of a plurality of downstream locations. The fluidic valve is provided with a primary supply port for receiving the second polymer melt flow, a pair of secondary supply ports which are fluid-connected with the primary supply port at a mixing intersection, and a plurality of discharge ports extending from the mixing intersection. Each discharge port directs the mixed flow of the first and second polymer melt flows to a respective downstream location. A pair of branch conduits is provided which fluid-connect one of the pair of outlet ports of the control valve to a respective one of the secondary supply ports of the fluidic valve.
