Zusammenfassung: | PURPOSE: To provide a simplified method and apparatus high in mass productivity and forming a semispherical two-color ball. CONSTITUTION: Curable liquid colored white and black are supplied to the upper and under surfaces of the disc 56 attached to a rotatable spindle (shaft) 58 by suitable distributing (dispensing) nozzles 52, 54. The liquids receive the influence of centrifugal force to move along the upper and under surfaces and together flow (without being mixed) so as to form a dichroic storage part 60 having parallel outer surfaces at the edge part of the disc 56 and a ligament 62 extends from the storage part 60 to distribute balls 10 at the terminal part of the storage part 60. |
