Abstract
Abstract A slicing and measuring apparatus for sausage and the like has a table which supports the foodstuff to be sliced and is displaceable back and forth adjacent a blade which is continuously rotated by an electric motor. The motor speed or current consumption is monitored to ascertain when the blade engages the foodstuff being sliced, and similarly the position of the table is monitored by means of a potentiometer. Thus it is possible to determine the diameter of the slice being produced, to square it and multiply it by an appropriate π containing factor and by the known thickness of the slice to determine the volume thereof. Thereafter this volume is mulitplied by the density of the foodstuff to determine the weight of the slice and the weight of successive slices can be added to determine the total weight sliced.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
175 words
A slice-measuring and -weighing method comprising the steps of: supporting a foodstuff to be sliced on a table adjacent a blade; relatively displacing said table and said blade in a predetermined stroke direction past each other to cut a slice from said foodstuff; generating an output when said blade engages into and cuts said foodstuff; continuously monitoring the relative positions of said table and said blade in said stroke direction; generating a width output corresponding to the relative position of said table and said blade on generation of said output and proportional to the width of the cut slice measured in said stroke direction; generating a thickness output corresponding to the thickness of said cut slice measured in a direction perpendicular to said stroke direction; generating a density output corresponding to the weight/volume density of said foodstuff; and combining said width and thickness outputs mathematically to form a volume output corresponding to the volume of said cut slice and combining said volume output with said density output to determine the weight of said cut slice.
Claim 2
Dependent Claim
175 words
A slice-measuring and -weighing method comprising the steps of: supporting a foodstuff to be sliced on a table adjacent a blade; relatively displacing said table and said blade in a predetermined stroke direction past each other to cut a slice from said foodstuff; generating an output when said blade engages into and cuts said foodstuff; continuously monitoring the relative positions of said table and said blade in said stroke direction; generating a width output corresponding to the relative position of said table and said blade on generation of said output and proportional to the width of the cut slice measured in said stroke direction; generating a thickness output corresponding to the thickness of said cut slice measured in a direction perpendicular to said stroke direction; generating a density output corresponding to the weight/volume density of said foodstuff; and combining said width and thickness outputs mathematically to form a volume output corresponding to the volume of said cut slice and combining said volume output with said density output to determine the weight of said cut slice.
Claim 3
Dependent Claim
51 words
