Abstract: An apparatus for topping a succession of regularly spaced pizzapie crusts on a conveyer with sliced topping material, such as cheese, comprising slicing means to cut blocks of the material on the conveyor into slices of appropriate shapes and sizes, and an automatic weighing means to supply appropriate amounts of the sliced material to the pizzapie crusts. The apparatus further includes an electrical control means which controls the operations of the above-mentioned means so that the operations will have a timed relationship with the movement of the pizzapie crusts, thereby placing each amount of sliced material on top of the corresponding pie crust with accuracy and without loss.
