Abstract
A bi-chromal ball production apparatus and method where the bi-chromal ball material is fed from opposite sides of the disk, reconfiguring the internal geometry of the apparatus, and precisely configuring the bi-chromal ball material feeding slit. The bi-chromal ball production apparatus has a disk that rotates, a first supply structure that supplies a first bi-chromal ball material to the disk from a first direction, a second supply structure tube that supplies a second bi-chromal ball material to the disk from a second direction and a motor that rotates the disk. The bi-chromal ball production apparatus includes a first reservoir and a first slit defined by the disk and a top body, a second reservoir and a second slit defined by the disk and a bottom body. An inner surface of each of the first and second reservoir is parabola shaped.
