ABSTRACT:
An improved apparatus for cutting and shaping a spherical body of a sticky material, composed of an assembly consisting of a number of rotary polygonal members for collectively forming an enclosure at the center thereof to cut and shape the material passing through the enclosure, each of the members with curved side surfaces being associated such that the enclosure is confined through the exposed part of the curved side surfaces of the polygonal members which pivotally swing to open and close the enclosure, and that the tip of each of the polygonal members tracks the exposed curved side surface of the adjacent polygonal member to scrape off the material adhering thereto, and each of the polygonal members having a uniform thickness that is thick enough to preclude the member from wedging into the material and that decreases toward the tip thereof, so that substantially spherical products can be continuously produced without generating any difficulty caused by the material adhering to the cutting members or by the filling protruding through the coating even when processing very sticky, soft materials.
