Abstract: A slicing system for automatically controlling the weight of individually sized portions of a sliced food product includes an automatic electric slicer and a scale operably associated therewith for weighing slices of a food product cut by the slicer. A photoelectric element disposed adjacent the path of the movable pointer on the scale detects the proximity of such pointer at a preselected location corresponding to a preselected weight of food product being received upon the receiving platform of the scale and opens the circuit to the slicer to stop the same. Adjusting means are provided to establish the relative position of the photoelectric element and the scale pointer for causing the circuit to break at such selected position.
