Abstract

PURPOSE:To obtain an expanded plastic having a pattern with more than one color by a method wherein an undiluted foaming solution is brought into the plural number of discharge nozzles, and a coloring ingredient is injected into >=2 optionally selected from the nozzles in which the ingredient is mixed with the solution. CONSTITUTION:An undiluted foaming solution is brought into a mixing chamber 17 and then the solution is introduced into the plural number of nozzles 4, 5, before being discharged from discharging nozzles 8, 9. At this time, a coloring ingredient is injected into the discharging nozzle 8 from a lead-in tube 6 to mix the ingredient with the solution, using an inline mixing device provided in the discharge nozzle 8, the colored mixture being discharged from the discharge nozzle 8. Next, the solution is allowed to foam, so that an expanded plastic with an entirely new multicolor pattern is obtained.
