Abstract: An apparatus for the production of ravioli and like products characterized by a base, sidewalls rising from the base, a forming roller rotatably coupled to the sidewalls, a platen roller rotatably coupled to the sidewalls in proximity to the forming roller, and means for feeding two sheets of ravioli dough and associated ravioli filling between the two rollers. The forming roller is generally cylindrical and is provided with a cutting grid around its curved surface and a number of ravioli forming areas located within the interstices of the cutting grid. Each ravioli forming area includes a centrally located, saddle shaped relief surrounded by at least one, but preferably two, sealing ridges.

Abstract: A food preparation machine primarily designed for the production of the Italian potato based delicacy gnocchi and characterized by an inclined flouring ramp, a motor driven roller located under the lower end of the ramp, a deflection plate located proximate the roller, and a dough extruder for depositing dough plugs near the top of the ramp so that they roll and slide down the ramp into abutment with the deflection plate and the roller. As the roller is rotated the dough plugs are squeezed through a gap between the roller and the lower edge of the deflection plate to take on the characteristic form of gnocchi. A flouring mechanism is provided to flour the parts of the machine that come into contact with the dough, including the ramp and a rotating knife blade which cuts the extruded dough into the plugs. The roller is threaded from both ends with opposing threads so that the plugs are urged towards the center of the roller as it is rotated.
