ABSTRACT:
The subject invention involves equipment for precision size reduction of a product, such as cutting string beans lengthwise into strips. More particularly, the invention is directed to improvement in the structure of a circular knife including a novel method of making its peripheral cutting edges by reducing the number of operations required to produce the knife. Previously, as presently known, the peripheral cutting edges of circular knives involves the expense of individually cutting material out of a peripheral area as compared to the unique method of the subject invention which simultaneously shears and forms offset portions and radial portions, and wherein the outer knife ends of these portions are simultaneously sharpened by a common bevel which causes the edges of the sharpened ends of the offset portions to be inset with reference to the sharpened ends of the radial portions. These two significant factors in the manufacture of circular knives constitute a meritorious advance in the art.
