ABSTRACT:
An improved apparatus for cutting and shaping a spherical material, including an assembly consisting of a number of rotary polygonal members for forming and closing an opening at their center to pass the material through the opening and cut and shape it. Each of the members has curved sides that abut each other when the members close the opening. The first side has a convex surface, and the second side has a concave surface. Each member is associated with each other such that the tip of each member tracks the convex surface of an adjacent member and when the members close the opening, the convex surface engages the concave surface so that substantially spherical products bearing no uneven flower patterns on their outer cover can be produced without any interruption of the operation of the apparatus caused by powder burning and sticking to the polygonal members.
