Abstract
Abstract The thickness of slices cut by an automatic slicing machine is controlled to produce a draft of slices having a predetermined weight. Desired thickness is determined in accordance with the cross-sectional density of the food product being sliced, which is obtained from the weight and thickness of the most recently cut slice or slices. This information is combined with a desired weight for each of the remaining slices to be cut in the draft to control the rate of advance of the food product into a continuously rotating knife so as to obtain the proper thickness.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A method for controlling the slicing of a food product to produce a draft of slices having a predetermined weight, comprising the steps of: cutting the food product to produce a slice thereof; determining the thickness of said slice; weighing said slice; determining the cross-sectional density of said slice from its thickness; and controlling the thickness of a subsequently cut slice in accordance with the determined cross-sectional density, the desired weight and a number of slices remaining to be cut in the draft to produce a final draft having said predetermined weight.
Claim 2
Independent Claim
92 words
A method for controlling the slicing of a food product to produce a draft of slices having a predetermined weight, comprising the steps of: cutting the food product to produce a slice thereof; determining the thickness of said slice; weighing said slice; determining the cross-sectional density of said slice from its thickness; and controlling the thickness of a subsequently cut slice in accordance with the determined cross-sectional density, the desired weight and a number of slices remaining to be cut in the draft to produce a final draft having said predetermined weight.
Claim 3
Dependent Claim
63 words
The method of claim 1 wherein said controlling step includes the steps of determining a desired slice weight for each of the slices that remain to be cut in the draft, dividing the desired slice weight by the determined cross-sectional density to obtain a desired thickness, and adjusting the speed of product advancement into a knife to produce slices of the desired thickness.
Claim 4
Dependent Claim
41 words
The method of claim 2 further including the steps of determining whether the desired thickness is outside of a range of predetermined thicknesses, and changing the number of slices in the draft when the desired thickness is outside of said range.
Claim 5
Independent Claim
140 words
A method for controlling the slicing of a food product, comprising the steps of: feeding the product into a moving blade at a known speed to cut slices having known thicknesses therefrom; weighing a group of slices cut from the product; determining the weight of a number of the most recently cut slices, which number is less than the total number of slices in said group; determining the cross-sectional density of said most recently cut slices on the basis of their weight and known thicknesses; determining a desired slice weight for the remaining slices to be cut in a draft containing said group of slices; determining a desired slice thickness on the basis of said cross-sectional density and said desired slice weight; and adjusting the speed of the feed rate of the product to produce slices of said desired thickness.
Claim 6
Independent Claim
140 words
A method for controlling the slicing of a food product, comprising the steps of: feeding the product into a moving blade at a known speed to cut slices having known thicknesses therefrom; weighing a group of slices cut from the product; determining the weight of a number of the most recently cut slices, which number is less than the total number of slices in said group; determining the cross-sectional density of said most recently cut slices on the basis of their weight and known thicknesses; determining a desired slice weight for the remaining slices to be cut in a draft containing said group of slices; determining a desired slice thickness on the basis of said cross-sectional density and said desired slice weight; and adjusting the speed of the feed rate of the product to produce slices of said desired thickness.
Claim 7
Dependent Claim
17 words
The method of claim 4 wherein said number of slices comprises only the most recently cut slice.
Claim 8
Dependent Claim
23 words
The method of claim 4 wherein the step of determining cross-sectional density includes dividing the weight of the slice by its known thickness.
Claim 9
Dependent Claim
42 words
The method of claim 4 further including the steps of determining whether the desired thickness is outside of a range of predetermined thickness values, and changing the number of slices in the draft when the desired thickness is outside of said range.
Claim 10
Independent Claim
95 words
A method for controlling the slicing of a food product to produce a draft of slices having a predetermined weight, comprising the steps of: cutting the food product to produce a slice thereof having a known thickness; weighing said slice; determining the cross-sectional density of said slice by dividing its known thickness into its weight; and controlling the thickness of a subsequently cut slice in accordance with the determined cross-sectional density, the desired weight and a number of slices remaining to be cut in the draft to produce a final draft having said predetermined weight.
Claim 11
Independent Claim
95 words
A method for controlling the slicing of a food product to produce a draft of slices having a predetermined weight, comprising the steps of: cutting the food product to produce a slice thereof having a known thickness; weighing said slice; determining the cross-sectional density of said slice by dividing its known thickness into its weight; and controlling the thickness of a subsequently cut slice in accordance with the determined cross-sectional density, the desired weight and a number of slices remaining to be cut in the draft to produce a final draft having said predetermined weight.
