Abstract: The knives on the surface of a peeler and grater disc for a vegetable peeling machine are formed from portions of the disc and are integral therewith. The knives are arranged in generally spiral rows from the center of the disc. Upturned reinforcing lips formed from and integral with the disc are located adjacent slots in front of each individual knife. The lips and knives cooperate to define the knife cutting depths. A pair of radially extending ribs on the disc cooperate with spiral ribs along the walls of the peeling chamber to promote circulation and rotation of all the vegetables for uniform exposure of all sides of all the vegetables to the disc.
