Abstract
A method of forming hemispheric bichromal balls, including the steps bringing together two streams of differently colored hardenable liquids for forming a single side-by-side bichromal stream, expelling said single side-by-side bichromal stream into a fluid as one or more free jets whose forward ends becomes unstable and break up into droplets which form into spherical balls, each of the balls comprising hemispheres of differently colored hardenable liquid, and finally hardening the balls.
Claims7
A method of forming multichromal balls, comprising the steps of
- providing a plurality of streams of differently colored hardenable liquids flowing in substantially the same direction,
- directing the lead ends of the streams towards each other,
- forming a single side-by-side multichromal stream as said plurality of streams merge together,
- moving said single side-by-side multichromal stream through a fluid medium as one or more free jets, so that their forward ends become unstable and break up into droplets which form into spherical balls, each of said balls comprising layers of differently colored hardenable liquid, and
- hardening said balls.
