Abstract:
1. A method for producing solidified articles having a predetermined composite pattern formed of at least two kinds of viscous fluids distinct from each other in color, said method comprising the steps of: supplying at least two kinds of viscous fluids distinct from each other in color separately at a predetermined ratio; introducing each of said separately-supplied viscous fluids into a first nozzle having opposing first and second ends and at least one first discrete passage per each of said viscous fluids for separately guiding throughout an entire length of said nozzle each of the viscous fluids, each of said first discrete passages having at least one first discrete passage inlet formed in said first end of said first nozzle, and a portion of said first discrete passages having a plurality of first discrete passage outlets formed in said second end of said nozzle, while at least one of said first discrete passages having one first discrete passage outlet formed in said second end of said nozzle, guiding each of said separately-supplied viscous fluids separately through said first discrete passages of the first nozzle to branch a portion of said viscous fluids, discharging each of said separately-guided viscous fluids through said first discrete passage outlets in said second end of the first nozzle in a larger number of streams than a number of said first discrete passage inlets, and receiving and solidifying all of said discharged viscous fluids.
