Method for stacking substantially flat products such as meat patties. Rows of patties are conveyed under a metal detector and then to a sigmoidal slide. Patties contaminated with metal trigger the metal detector to send a signal to the slide. Upon receipt of a signal from the metal detector, the slide pivots in a manner to dispose of metal contaminated patties. Uncontaminated patties are conveyed down the slide without flipping over and onto a second lower conveyor having a plurality of vertical blades mounted thereto, between which patties are received in stacks. An optical counter is mounted to count patties conveyed down the slide. The counter is in communication with the second indexed conveyor and signals such conveyor to move forward after a predetermined number of patties have been stacked between two adjacent vertical blades on the indexed conveyor. Stacks of patties are then conveyed on the second conveyor to a packing station where workers can grasp the stacks with each of their hands for packing into distribution boxes.
