A device for the production of a food article, in which food material is extruded through a generally arcuate die opening so that a differential in the frictional forces between the center portion and the end portions of the arcuate opening causes the material to curl about an axis transverse to the die axis and thus assume the general shape of a shell. The device lends itself to the fabrication, in an automatic, consistent and simple way, of a food product of a unique structure which has a filling of meat within a covering of dough.
