Abstract
Abstract A slicing machine for slicing a product, comprising a blade 1 and a feeding mechanism 8, 9, 11, 12, to feed the product towards the blade 1 also includes a programmed computer 18 to control the feed rate of the feeding mechanism 8, 9, 11, 12 and programmed with a function corresponding to the typical weight distribution of at least one type of product. The computer 18 is programmed to respond to the input of information representing the weight and length of a particular product to modify the typical weight distribution function in accordance with the input values to provide an anticipated weight distribution for that particular product. The computer is also programmed to control the operation of the feeding mechanism 8, 9, 11, 12, so that the product is fed towards the blade 1 at a rate which varies with the anticipated weight distribution.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
A method of slicing a non-uniform product comprising weighing said product, measuring the overall length of said product, using said weight and length measurements in conjunction with a weight distribution function for products of that type to establish an anticipated weight distribution for that said product, and then controlling the feed rate of said product through a slicing machine in dependence upon said established anticipated weight distribution.
Claim 2
Independent Claim
67 words
A method of slicing a non-uniform product comprising weighing said product, measuring the overall length of said product, using said weight and length measurements in conjunction with a weight distribution function for products of that type to establish an anticipated weight distribution for that said product, and then controlling the feed rate of said product through a slicing machine in dependence upon said established anticipated weight distribution.
Claim 3
Dependent Claim
164 words
In a slicing machine for slicing a non-uniform product in accordance with its anticipated weight distribution including a rotatable slicing blade, and feed means to feed said non-uniform product towards said rotatable blade, the improvement wherein the machine also comprises a programmed computer arranged to control said feed means, and input means to input information relating to weight of said non-uniform product into said programmed computer, said programmed computer being programmed with a function corresponding to a non-linear weight distribution for at least one type of product and being programmed to respond to information input by said input means to modify said typical non-linear weight distribution function in accordance with said input information to derive an anticipated weight distribution for said product, said computer being programmed then to control operation of said feed means in accordance with said derived anticipated weight distribution for said product, whereby said product is fed towards said blade at a rate which varies with said derived anticipated weight distribution.
Claim 4
Dependent Claim
164 words
In a slicing machine for slicing a non-uniform product in accordance with its anticipated weight distribution including a rotatable slicing blade, and feed means to feed said non-uniform product towards said rotatable blade, the improvement wherein the machine also comprises a programmed computer arranged to control said feed means, and input means to input information relating to weight of said non-uniform product into said programmed computer, said programmed computer being programmed with a function corresponding to a non-linear weight distribution for at least one type of product and being programmed to respond to information input by said input means to modify said typical non-linear weight distribution function in accordance with said input information to derive an anticipated weight distribution for said product, said computer being programmed then to control operation of said feed means in accordance with said derived anticipated weight distribution for said product, whereby said product is fed towards said blade at a rate which varies with said derived anticipated weight distribution.
Claim 5
Dependent Claim
36 words
The slicing machine of claim 1, wherein said weighing means includes a platen on which said product is placed, and a load cell for producing said first electrical signal, said platen bearing on said load cell.
Claim 6
Dependent Claim
24 words
The slicing machine of claim 3, wherein said platen also includes an abutment, and wherein said length measuring means is associated with said platen.
Claim 7
Dependent Claim
48 words
The slicing machine of claim 4, wherein said length measuring means is formed by a caliper arm and a potentiometer, said caliper arm being movably mounted on said platen and movable with respect to said platen, movement of said arm along said platen effecting actuation of said potentiometer.
Claim 8
Dependent Claim
28 words
The slicing machine of claim 4, wherein said length measuring means includes an ultrasonic distance measuring device mounted adjacent an end of said platen remote from said abutment.
Claim 9
Dependent Claim
38 words
The slicing machine of claim 2, which also includes a jump conveyor, said jump conveyor being located downstream from said blade; operation of said jump conveyor to produce groups of slices also being controlled by said programmed computer.
Claim 10
Dependent Claim
69 words
The slicing machine of claim 7, further comprising a gyratory mechanism driving said rotatable blade, and wherein said computer also controls rotation and gyration of said blade, and, in response to a manual change in the speed of gyration to control the rate at which slices are cut, automatically resets the speed of rotation of said blade to maintain a predetermined ratio between its speeds of rotation and gyration.
Claim 11
Dependent Claim
68 words
The slicing machine of claim 2, wherein said input means comprises weighing means to weigh said product, to produce a first electrical signal representing its said weight and to input said first signal into said programmed computer, and length measuring means to measure the length of said product, to produce a second electrical signal representing its said length and to input said second signal into said programmed computer.
