Abstract

Methods and apparatuses for cutting food products. The apparatus includes an annular-shaped cutting head having at least a first mounting frame surrounding a central axis of the cutting head and a plurality of cutting tools arranged around the central axis of the cutting head and pivotably coupled to the first mounting frame such that each cutting tool has a pivot axis. The method includes deflecting each cutting tool about its pivot axis by engaging first portions of the cutting tools in proximity to the first mounting frame to deflect the first portions a first radial deflection distance relative to the central axis and engaging second portions of the cutting tools to deflect the second portions a second radial deflection distance relative to the central axis. The first and second radial deflection distances can be adjusted individually or in unison.

First claim

The invention claimed is:

1. An apparatus for cutting food products, the apparatus having an annular-shaped cutting head comprising:
at least a first mounting frame surrounding a central axis of the cutting head;
a plurality of cutting tools arranged around the central axis and pivotably coupled to the first mounting frame such that each of the cutting tools has a pivot axis;
first deflecting units engaging first portions of the cutting tools in proximity to the first mounting frame to deflect the first portions a first radial deflection distance relative to the central axis;
second deflecting units engaging second portions of the cutting tools to deflect the second portions a second radial deflection distance relative to the central axis, the second portions of the cutting tools engaged by the second deflecting units being spaced apart from the first portions of the cutting tools and being positioned farther from the first mounting frame than the first portions such that the first deflecting units and the second deflecting units associated with one of the cutting tools make discontinuous contact with the cutting tool; and
an adjustment mechanism that includes at least one lever to alter the first radial deflection distance and the second radial deflection distance of the first portions and the second portions of the cutting tools, respectively, wherein the adjustment mechanism is operable to alter the first radial deflection distances in unison with each other and the second radial deflection distances in unison with each other.

2. The apparatus of claim 1 , wherein the cutting tools define sequential pairs of the cutting tools in which one of the cutting tools of each sequential pair is a leading cutting tool of the sequential pair and an adjacent one of the cutting tools is a trailing cutting tool of the sequential pair, each of the cutting tools having a cutting blade positioned at a leading side of the cutting tool and a trailing edge positioned at a trailing side of the cutting tool opposite the leading side, the trailing edge of each of the leading cutting tools cooperating with the cutting blade of the trailing cutting tool thereof to define a cutting gap therebetween, each of the cutting tools being rotatable about the pivot axes thereof between a first rotational position in which the cutting gap has a first gap width and a second rotational position in which the cutting gap has a second gap width that is different from the first gap width.

3. The apparatus of claim 2 , wherein the second gap width is less than the first gap width such that the cutting head is configured to produce slices of the food products that are thinner when the cutting tools are positioned at the second rotational positions thereof than when the cutting tools are positioned at the first rotational positions thereof.

4. The apparatus of claim 2 , wherein the trailing edges of the cutting tools are located a first radial distance from the central axis when the cutting tools are positioned at the first rotational positions and are located a second radial distance from the central axis when the cutting tools are positioned at the second rotational positions, wherein the second radial distance is less than the first radial distance.

5. The apparatus of claim 2 , wherein the first deflecting units and the second deflecting units each engage the trailing sides of the cutting tools, and the pivot axis of each of the cutting tools is located adjacent the cutting blade of the cutting tool thereof.

6. The apparatus of claim 1 , further comprising a second mounting frame surrounding the central axis of the cutting head and spaced apart from the first mounting frame along the central axis, wherein the cutting tools are disposed between and pivotably coupled to the first mounting frame and the second mounting frame, and the second deflecting units engage the second portions of the cutting tools in proximity to the second mounting frame.

7. The apparatus of claim 1 , further comprising a biasing member to maintain engagement of the cutting tools with the first deflecting units and the second deflecting units, wherein the first deflecting units and the second deflecting units are formed to serve as adjustable stops for the cutting tools.

8. The apparatus of claim 7 , wherein the a biasing member biases the cutting tools radially outward away from the central axis to maintain engagement of the first deflecting units and the second deflecting units with the first portions and the second portions of the cutting tools, respectively.

9. The apparatus of claim 8 , wherein the biasing member is connected to the cutting tools and engages at least the first mounting frame.

10. The apparatus of claim 1 , wherein the first deflecting units and the second deflecting units each comprise a cam that is rotatable about a camming axis between a first camming position in which the cutting tools are located at a first rotational position and a second camming position in which the cam deflects the cutting tools toward a second rotational position.

11. The apparatus of claim 10 , wherein the cams of the first deflecting units and the second deflecting units are independently rotatable about the cam axes thereof and operable to deflect the first portions and the second portions of the cutting tools so that the first radial deflection distance and the second radial deflection distance are capable of being different.

12. The apparatus of claim 10 , wherein the cams of the first deflecting units and the second deflecting units are coupled to rotate in unison about the camming axes thereof and are operable to deflect the first portions and the second portions of the cutting tools.

13. The apparatus of claim 12 , further comprising a coupler configured to couple and decouple the cams of the first deflecting units and the second deflecting units so that the cams are capable of being independently rotated about the cam axes thereof and operable to deflect the first portions and the second portions of the cutting tools so that the first radial deflection distance and second radial deflection distance are capable of being different.

14. The apparatus of claim 1 , wherein the first deflecting units and the second deflecting units are coupled to operate in unison to deflect the first portions and the second portions of the cutting tools, and the deflection operating system comprises levers coupled to the first deflecting units and operable to rotate the first deflecting units and the second deflecting units in unison to deflect the first portions and the second portions of the cutting tools.

15. The apparatus of claim 14 , further comprising a coupler configured to couple and decouple the first deflecting units and the second deflecting units so that the first deflecting units and the second deflecting units are capable of being independently rotated to deflect the first portions and the second portions of the cutting tools so that the first radial deflection distance and the second radial deflection distance are capable of being different.

16. The apparatus of claim 14 , wherein the adjustment mechanism further comprises a control ring having an axis of rotation about the central axis, the control ring being coupled to the levers to rotate the first deflecting units and the second deflecting units in unison.

17. The apparatus of claim 16 , wherein the control ring is coupled to the levers so as to be secured by the levers to one of the upper mounting frame or the lower mounting frame.

18. The apparatus of claim 1 , further comprising a f
