Abstract: An apparatus and method for forming images in pie tops. The apparatus provides a frame, a cylindrical die having an image surface, a cover, a counter surface and a pie top conveyor. The die is rotatably attached to the frame and may be removed to change to other dies having different image surfaces. The counter surface provides resistance to the point of formation in the pie top. The pie top conveyor transports a continuous or non-continuous top sheet of pie dough between the die and the counter surface. The conveyor and die are made with substantially non-compressible and non-stick surfaces. After an image is formed in the top sheet of pie dough, the sheet is transported from the exit of the die to a corresponding pie bottom located on a lower conveyor and then to an oven for baking.

Abstract: A conveyor moves food product, such as pies or cakes, within a cutting range of a knife positioning assembly. The knife positioning assembly supports an ultrasonic knife assembly which has a blade adapted for cutting the food product. The knife assembly is disposed above the conveyor and is moved to the food product in a cutting position therewith when the conveyor has moved the food product within the cutting range. The knife assembly is movable through at least two axes by the positioning assembly for positioning and cutting with the blade.
