Abstract: The present invention relates to a dynamic weight control system for a slicing machine, used to slice bacon or other food products, that has both primary and secondary weighing systems. The slicing machine has a slicing blade and a feed mechanism for feeding a food product (e.g., a bacon slab) into the slicing blade at a controlled rate. The primary weighing system controls primary slicing and weighing of multi-slice drafts of the sliced products so that each draft is an approximation of a prescribed control weight. The secondary weighing system checks draft weights and supplies data to a computer that computes an average weight for those drafts that are within an acceptable weight range; it also computes the pass ratio of acceptable weight drafts for a sample group of drafts.
