ABSTRACT:
A cutting apparatus for cutting objects into minute pieces with high exactitude and high precision comprises, as an integral unit, a pair of cutter shafts disposed substantially in parallel to each other, a motor attached to one of the cutter shafts, gears for rotating the other cutter shaft in a direction opposite to the direction in which the one cutter shaft is rotated, a plurality of substantially disk-like cutters fitted around each of the cutter shafts, and a plurality of substantially disklike spacers fitted around each of the cutter shafts. The cutters and spacers around each of the cutter shafts are alternately arranged and brought into intimate contact with each other in the axial direction of each of the cutter shafts. The cutters and the spacers around the one cutter shaft are closely opposed respectively to the spacers and the cutters around the other cutter shaft so as to hold the cutters on the respective shafts in mesh with each other. The cutting apparatus further comprises a dish-shaped shoot which is disposed at a position immediately above the cutters and spacers for effectively guiding the objects onto the cutters and spacers to enhance the cutting efficiency, and a pair of scrapers which are disposed on the sides of the cutters opposite that on which the cutters and the spacers are opposed, and which are provided with corrugated engaging claws for engaging with the cutters and the spacers to effectively prevent the objects from falling from between the cutters and spacers.
