Abstract
A revolving cylindrical escapement extrusion apparatus for shaping foodstuff articles of the type having a nozzle orifice slot and means for feeding foodstuff material under pressure for extrusion through this elongated orifice. A cylindrical escapement valving member revolves adjacent to the downstream side of an adjustable orifice slot and preferably includes at least two axially spaced and circumferentially overlapping openings in its cylindrical perimeter for shaping foodstuff blanks, and it revolves its shaping openings in front of the adjustable orifice slot for controlling the extrusion of foodstuff material through the slot to shape the material into product blanks. By virtue of having at least two circumferentially overlapping openings in the revolving cylindrical escapement member there is achieved a continuing flow of the material being extruded. As the escapement member is diminishing the flow rate being shaped by one of its openings it is concurrently increasing the flow rate being shaped by another of its openings, thereby producing an aggregate flow which continues and in which the flow rate does not unduly surge.
