Abstract Automatic machine and method for determining the depth or thickness of a layer of fat on a meat section or cut during transport by a moving conveyor, first through a measuring station involving employment of a bank of individually-operable probes arranged transversely of the conveyor travel and intermittently extendable toward and retractible from the meat section, the probes being used to successively measure a plurality of local values in a plurality of sites as they penetrate the fat layer and generate signals representative of those local values for transmittal to and storage in a memory bank as a profile of the fat layer, and second through a trimming station involving employment of an endless band saw having a working run extended transversely of and above the meat section cooperant with means for effecting lateral displacement of portions of the saw blade from the normal reference position responsive to signals from the memory representative of the profile for the prepositioning of the saw blade relative to the various probed sites of meat section preparatory to the trimming of a predetermined thickness of the fat thereat.
A method of trimming the fat layer from a meat cut comprising the steps of: measuring the local values of the depth of the fat layer by probing the meat cut in a plurality of sites as the meat cut is conveyed past a first measuring station, generating a plurality of signals representing the depth measurements at the respective sites, storing the generated values in a memory as representative of the fat profile, conveying the meat cut past a second trimming station, moving an endless band saw blade in a path transverse to the direction of movement of and around the meat cut with the run of the blade above the meat cut being laterally and vertically displaced along the transverse path from its normal reference position according to the generated fat profile by a profile sensing member activated by and responsive to the values stored in the memory.

In a meat trimming method, the steps of conveying the cut through a measuring station, measuring the local values of the depth of the fat layer by probing the cut in a series of sites as the cut is incrementally conveyed through a measuring station, generating and storing in a memory terminal an ordered succession of value data sequences as a fat profile representative of the generated signals corresponding to the depth of the probes in the respective sites, conveying the cut through a trimming station, cutting the fat from the cut by a series of cuts by a band saw blade driven in an endless path having a run extendable transverse to and above the direction of movement of the cut with the run of the blade being laterally and vertically displaced along the run from its normal reference position responsively to the generated profile created by a profile sensing member activated by and responsive to the value data stored in the memory terminal.
