S P E C I F I C A T I O N FRENCH FRY CUTTER FOR FOOD PROCESSORS Inventor : Koichiro Shibata ABSTRACT OF THE DISCLOSURE A French fry rotary cutter tool is provided for use in food processors of the type having a working bowl with tool drive means extending into the bowl for rotating the tool in the bowl and a removable cover for closing the bowl when in use with a feed passageway for introducing food material into the bowl. The French fry cutter has a hub removably engageable with the drive means and a disc-like member secured to the hub. The disc-like member has an opening extending from a region near the hub to a region near the periphery and there is an elevated portion on the member located behind the opening with respect to the direction of rotation of the disc-like member. A cutting structure is positioned in the opening for producing multiply closely, spaced elongated rectangular shaped cuts in food items such as potatoes, applied there-to, with the resulting French fry cut food passing through the opening into the bowl. In accordance with the present inven- tion, a cutting structure is formed of a continuous strip of blade metal bent into a rectangular-wave shape (rectangular zig-zag shape) and having alternating, spaced flat, lower portions and spaced, flat, upper portions which are secured, respectively, to the underside and to the elevated portion of the disc-like member. This bent blade strip thus advantageously defines a plurality of spaced, upright, parallel blades extending upwardly, generally perpendicular to, and located between and integral with the spaced flat lower and spaced, flat, upper portions of the bent blade strip. Consequently, the cutting structure has a square-wave appearance as viewed forwardly or rearwardly. The leading, cutting edge of the blade strip is advantageously sharpened before it is bent into shape, and therefore each of the upright blades and each of the flat upper portions have sharp leading edges facing forward in the direction of the rotation of the disc for simultaneously pro- ducing horizontal and vertical cutting in food items applied thereto for forming clean, crisp, neat, elongated, rectangular shaped French fry cuts. The cutting structure is ruggedized by a flat plate-like blade element with a sharpened leading edge which is mounted on and projects forward from the elevated platform portion of the disc-like member. In addition, the trailing edges of the spaced upper and lower portions of the square-wave-shaped, bent blade strip have rearwardly extending integral tongues which are respectively secured to said flat plate-like element and to integral rearwardly extending tongues of said disc-like member. -2-
