A sandwich cookie is made of a chocolate-coated bottom biscuit and a plain top biscuit by applying a pair of stripes of molten chocolate to the chocolate-coated surface of the bottom biscuit, placing the biscuits against each other, and cooling the molten chocolate to set it and bond together the top and bottom biscuits to form the desired chocolate sandwich cookie. Apparatus is provided for performing these steps automatically on rapidly-moving trains of top and bottom biscuits. Stepping conveyors and synchronized lugged conveyors move each top biscuit into vertical alignment with a corresponding coated and striped bottom biscuit, whereupon the top biscuit is dropped upon the bottom biscuit and passed beneath a presser spring which urges the top and bottom cookies toward each other prior to cooling of the molten stripes. The bottom biscuits are initially provided with the chocolate coating on their bottom surfaces, and are turned over prior to application to them of the top biscuits, by means of synchronously rotating inverter wheels having recesses for receiving the bottom biscuits and for carrying them around to an inverted, coated-side-up, position prior to their discharge onto the conveyor. |
