Abstract
Abstract A combination bacon slicing, segregating and weighing machine is provided. The slicing machine has a slicing blade and controls for determining the rate of feed of the bacon belly towards the slicing blade and, consequently, the slice thickness. Receiving and conveying structure is associated with the weighing machine and receives the sliced product coming from the slicing machine. Control apparatus is designed for interruption of the operation of the feeding mechanism by appropriate controls when the slices are at a weight less than the prescribed draft weight. The apparatus then provides for weighing and registering the weight of the accumulated light weight group of sliced product and for counting the number of slices in the lighter group. The apparatus calculates by subtracting the weight of the group from a heavier draft target weight and multiplying the weight difference by the ratio of the slices in the lighter group to the weight of the lighter group to determine the number of slices to be added to produce the target weight without changing the slice thickness. The number of slices required for the target weight rounded out to the nearest whole integer is then calculated. Thereafter, the error produced by rounding off to the nearest whole integer is corrected by multiplying the first feed rate by the ratio of the number of slices calculated to produce the target weight by the number of slices rounded off to the nearest integer to provide a new feed rate which will produce a number of whole slices at the right thickness in making up the added weight to produce the draft target weight.

Claim 1
Independent Claim
337 words
A combination slicing and weighing machine comprising: a slicing machine having a slicing blade and a feed mechanism for feeding products to be sliced with the slicing blade; receiving and conveying means for receiving the sliced product coming from the slicing machine; scale means coupled with the receiving and conveying means for weighing the weight of the sliced product, the scale means being so constructed and arranged to weigh the sliced product at an initial lighter group weight below a heavier draft target weight; first control means for interrupting the operation of the feeding mechanism when the scale registers the initial group weight and when a draft has been completed; means for counting the number of slices in the group of sliced product and particularly the number of slices in the lighter group and to be added to reach the heavier draft target weight; second control means for determining the rate of advance of said feeding mechanism towards such slicing blade and, consequently, the sliced thickness, said second control means feeding the product at a first feed rate and a second feed rate; calculating means for subtracting the weight of the initial lighter group from the heavier target weight, and multiplying the weight difference by the ratio of the slices in the initial lighter group to the weight of this group to determine the number of slices to be added to produce the heavier draft target weight without changing the slice thickness; means for calculating the number of slices required to be added for the heavier draft target weight rounded off to the nearest whole integer; and means for correcting the weight error produced by rounding off to the nearest whole integer by multiplying the first feed rate by the ratio of the number of slices calculated to produce the target weight by the number of slices rounded off to the nearest integer to provide a new second feed rate which will produce a whole number of slices at the thickness to produce the draft target weight.
