Description
Title: 2-PIECE CUTTER BLADE FOR PRODUCING
HELICAL VEGETABLE STRIPS
FIELD OF THE INVENTION
This patent application relates generally to an apparatus for mass producing helical vegetable strips, and specifically to a rotating cutter used on such an apparatus. French fried potatoes and other vegetables of generally spiral or helical shape have become increasingly popular.
Consumers like them because of their interesting appearance, and they are appealing to institutional food providers and restauranteurs because a given volume of french fries has more plate coverage when they are of helical shape.
Systems for cutting helical french fries are currently available in the marketplace. The cutters in many of the systems are disk-like in nature; that is, the cutter which slices the potatoes or other vegetables into helical strips is generally a substantially flat or helical circular plate having a knife blade or "slabber blade" extending from the axis of rotation to the periphery of the disk. Mounted directly on the front face of the disk is a plurality of slitter blades. The slitter blades are located at different radii from the axis of rotation and sometimes are spaced with a radial pitch to one another.
The previously described rotating cutters are used in conjunction with various feed systems to feed whole potatoes into the rotating cutter. One such feeding means is a hydraulic feed system. In such a system, potatoes are placed in a hydraulic medium which is pumped through a conduit. The outlet of the conduit is positioned to be in alignment with the rotating cutter. The potatoes are transported to the rotating cutter by the hydraulic medium.
The slitter blades extending from the surface of the cutter first contact the potato and score it. The locations of the slitter blades and their spacing from each other determine the width of each helical potato strip to be cut. The Blabber blade then cuts each helical strip into a desired SUBSTITUTE SHEET (RULE 26)

A problem encountered with this type of cutting system , involves the repair, maintenance or replacement of the slitter blades themselves. The slitter blades are relatively thin compared to the disk and have a tendency to dull, bend or break and must be sharpened, repaired or replaced frequently, often more than once a day.

As a result, the disk which incorporates the slabber blade has to be replaced much less frequently than the slitter blades. Since the slitter blades are mounted or affixed directly to the surface of the cutter disk in the prior art, the entire cutter disk must ordinarily be removed from the feed system in order to resharpen, repair, clean or replace one or more of the slitter blades, thus making the system completely inoperable until maintenance has been completed and the cutter disk replaced in the system. This results in an increase in down-time and a decrease in productivity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Turning now to FIGS. 1, 2, and 3, there is depicted a cutter assembly 20 for cutting potatoes into generally helically shaped strips, which cutter incorporates the features of the present invention. Cutter 20 comprises a circular disk 21 having several apertures 23 in its interior and a plurality of slots, 22a, 22b, 22c, 22d, and 22e, radiating from the center of the disk towards the outer periphery. Preferably, the slots are arranged in a shallow arc. Disk 21 is slit radially to produce a pair of edges 24 and 25 which are substantially parallel, spaced from each other and axially displaced. The leading edge 25 is sharpened to create a cutter blade ordinarily known as a slabber blade. In a preferred embodiment of the present invention, disk 21 has a substantially flat first part extending approximately 100° in an arc between edge 24 and phantom line 29, and a raised second part extending approximately 260° in an arc between phantom line 29 and Blabber blade 25. In another embodiment. disk 21 may be formed into a right helicoid beginning at edge 24 and terminating at raised edge 25 and having a substantially uniform pitch therebetween.
In either embodiment, the slabber blade 25 is integral with and formed from the disk 21 and axially displaced from the front surface of the disk 21.
The Blabber blade 25 is axially displaced from the front surface of the disk so that the cutter disk will cut helical strips of even thickness. The Blabber blade 25 does not have to be integral with and formed from the disk 21, and can be a separate blade axially displaced from and attached to the front surface of the disk 21 by screws or other securing means which are readily SUBST1TLJTE SHEET (RULE 26) _5_ , known in the art. In all embodiments, a quill or center tube 27 projects axially from the center of disk 21. The quill may be solid or hollow.
Turning now to FIG. 4, in a preferred embodiment, five slitter blades, 33a, 33b, 33c, 33d, and 33e, are one piece and formed from a removable slitter plate or insert 33 for mounting on the disk 21. In another embodiment, the slitter blades may be separate from and secured to the plate. The slitter blades, 33a, 33b, 33c, 33d, and 33e, are arranged on the removable insert 33 to correspond and align with the slots, 22a, 22b, 22c, 22d, and 22e, respectively, on disk 21. Slitter plate 33 includes a slot on the side away from blades 33a-a and also two notches 35 on the other side, adjacent blades 33a and 33e, respectively. The removable plate 33 may be secured to the disk 21 by a variety of means, such as by screws and nuts extending through aligned holes in the disk 21 and plate 33. Ln a preferred form, a backing plate 36 is provided to aid in securing plate 33 to disk 21.
The backing plate 36 includes three threaded screw holes which align with three threaded screw holes on the disk 21. Backing plate 36 includes projection 37 centrally on one side and two projections 38 respectively at the ends of the other side. When the parts are assembled, projection 37 is located in slot 34 and projections 38 fit into notches 35, respectively. The backing plate 36 is removably secured to the back surface of the disk 21 with three screws such that the plate 33 opposes the back surface of the disk 21 and the backing plate 36 and is trapped therebetween. Thus, the slitter plate 33 is captured between backing plate 36 and disk 21. Also, projection 37 being in slot 34 and projections 38 being in notches 35, lateral movement of slitter plate 33 is prevented. In this way, no holes have to be made in the insert.
Preferably, the slitter blades, disk, and removable backing plate are made of steel and are approximately 0.89 mm (0.035 inches), 3.56 mm (0.140 inches), and 1.52 mm (0.060 inches) in thickness, respectively.
In operation of the cutting assembly, the cutter rotates counterclockwise. Blade 33a is innermost, and, as the cutting disk rotates, leads blade 33b. In a similar manner, blade 33c is next and trails blade 33b.
AM~NDEO SHEET
WO 96!37349 PCT/CA96/00340 Blade 33d is next and trails blade 33c. Blade 33e is outermost and trails blade 33d. In one operative embodiment, the angles between edge 24 and , the mid-points of blades 33a, 33b, 33c, 33d, and 33e are, respectively, about 44.0°, 30.6°, 19.7°, 10.4°, and 3.1°.
In operation, a potato is propelled into cutter 20 by a feed means (not shown). As the potato approaches cutter 20, it first contacts quill 27 which keeps the potato axially aligned with the axis of the quill.
Because of the rounded shape of the end of the potato, the point of slitter blade 33a first makes contact with the front end of the potato during the first rotation of cutter 20, and blade 33a begins scoring the potato concentrically about the longitudinal axis of the potato. Then blade 33b starts scoring the potato. The slabber blade starts cutting even before the outer slitter blades score the potato. Finally, blades 33c, 33d, and 33e start to cut. As the potato continues to be fed into cutter 20, it contacts edge 25 which begins cutting the potato transversely to the longitudinal axis of the potato, thereby forming helical strips. The widths of the strips are determined by the spacing between adjacent slitter blades. It will be appreciated by those skilled in the art that the number of slitter blades may vary to include more or less than five as a particular application may require.
This construction increases the productivity of said cutter by decreasing maintenance down-time. When one or more slitter blades need to be resharpened, cleaned, repaired or replaced, the removable slitter blade insert can be quickly and easily removed for cleaning, resharpening, repair and immediate replacement with a substitute slitter blade insert. In this way, maintenance down-time is significantly decreased thereby substantially increasing productivity. , What has been described, therefore, is an improved cutter for cutting vegetables into helical strips incorporating a removable plate incorporating slitter blades. Productivity is significantly increased by decreasing maintenance down-time through the use of a removable slitter blade insert.

In either embodiment, the slabber blade 25 is integral with and formed from the disk 21 and axially displaced from the front surface of the disk 21.
The Blabber blade 25 is axially displaced from the front surface of the disk so that the cutter disk will cut helical strips of even thickness. The Blabber blade 25 does not have to be integral with and formed from the disk 21, and can be a separate blade axially displaced from and attached to the front surface of the disk 21 by screws or other securing means which are readily SUBST1TLJTE SHEET (RULE 26) _5_ , known in the art. In all embodiments, a quill or center tube 27 projects axially from the center of disk 21. The quill may be solid or hollow.
Turning now to FIG. 4, in a preferred embodiment, five slitter blades, 33a, 33b, 33c, 33d, and 33e, are one piece and formed from a removable slitter plate or insert 33 for mounting on the disk 21. In another embodiment, the slitter blades may be separate from and secured to the plate. The slitter blades, 33a, 33b, 33c, 33d, and 33e, are arranged on the removable insert 33 to correspond and align with the slots, 22a, 22b, 22c, 22d, and 22e, respectively, on disk 21. Slitter plate 33 includes a slot on the side away from blades 33a-a and also two notches 35 on the other side, adjacent blades 33a and 33e, respectively. The removable plate 33 may be secured to the disk 21 by a variety of means, such as by screws and nuts extending through aligned holes in the disk 21 and plate 33. Ln a preferred form, a backing plate 36 is provided to aid in securing plate 33 to disk 21.
The backing plate 36 includes three threaded screw holes which align with three threaded screw holes on the disk 21. Backing plate 36 includes projection 37 centrally on one side and two projections 38 respectively at the ends of the other side. When the parts are assembled, projection 37 is located in slot 34 and projections 38 fit into notches 35, respectively. The backing plate 36 is removably secured to the back surface of the disk 21 with three screws such that the plate 33 opposes the back surface of the disk 21 and the backing plate 36 and is trapped therebetween. Thus, the slitter plate 33 is captured between backing plate 36 and disk 21. Also, projection 37 being in slot 34 and projections 38 being in notches 35, lateral movement of slitter plate 33 is prevented. In this way, no holes have to be made in the insert.
Preferably, the slitter blades, disk, and removable backing plate are made of steel and are approximately 0.89 mm (0.035 inches), 3.56 mm (0.140 inches), and 1.52 mm (0.060 inches) in thickness, respectively.
In operation of the cutting assembly, the cutter rotates counterclockwise. Blade 33a is innermost, and, as the cutting disk rotates, leads blade 33b. In a similar manner, blade 33c is next and trails blade 33b.
